Another further scheme is possible.

Component can be the rubberized fabric for offset printing appts.Utilize functional polymer can change the hardness of the elastomeric cover of rubberized fabric.The adjustment of hardness can be carried out according to printable fabric, prints described printable fabric with rubberized fabric.Different rubberized fabric hardness can be regulated for different printable fabrics.The advantage drawn thus is, no longer needs multiple different rubberized fabric for different printable fabrics, but needs only one and identical general purpose rubber cloth.Therefore, rubberized fabric storage level and the storage area that for this reason arranges can be made to minimize.Attendant advantages eliminates debug time, needs described debug time when usually changing rubberized fabric between the print job with different printable fabrics.By field being applied to the hardness that functional polymer can change rubberized fabric.At this, described field can be changed about its intensity and/or frequency and be applied in pulse.Described field can be applied to, so that the elastic hardness of the expectation of adjustment means with different impulse forms and pulse duty factor (pulse interval ratio).Described field is applied on functional polymer on the position that the character expected changes; Described functional polymer is impression gap when rubberized fabric.By electroactive polymer (EAP) as in functional polymer, described field is electric field.In use magnetic living polymer (MAP), described field is magnetic field.Different printable fabrics needs surface pressings different between rubberized fabric and printable fabric and different contact zones width in impression gap, therefore, refers to the ellipticity of the rubberized fabric in impression gap.When being expressed on printable fabric by rubberized fabric with predetermined extruding force, utilize functional polymer can change the elastic hardness of rubberized fabric and change surface pressing and contact zones width in addition.Under predetermined " theoretical body invades " (be provided to by the blanket cylinder with rubberized fabric in the counter-pressure cylinders with printable fabric and cause compression distance thus), functional polymer is utilized to change the elastic hardness of rubberized fabric and change surface pressing in addition.Utilize functional polymer not only can change contact zones width between rubberized fabric and printable fabric and surface pressing, and the contact zones width that can change between rubberized fabric and clearer and surface pressing.If rubberized fabric is not positioned on blanket cylinder (offset cylinder), but be positioned at (such as anilox printing unit) in ink application roll, so by utilizing described field to manipulate functional polymer, the contact zones width between ink application roll and plate cylinder and/or between ink application roll and silk screen roller and/or surface pressing can be regulated in roller gap.

In order to change the elastic hardness of character, the in this case rubberized fabric of component, there are two kinds of basic possibilities by means of the functional polymer being configured to EAP.Or, such as, when described functional polymer is insulating polymer, directly voltage is applied on functional polymer by means of electrode.Or functional polymer stands outside electric field non-contactly, described electric field produces the tensile force of so-called inside by making dipole orientations that is that respond in functional polymer (EAP material) or permanent magnetism.In the modification with electrode, described electrode can be configured to integrated surface electrode, and described surface contacts with the EAP layer of electrode elastic.Corresponding surface electrode can be structurized and on the whole surface of EAP layer or only extend in the part on described surface.Also the surface electrode that can contact multiple, separated from one another can be arranged on the one or both sides of EAP layer.But flexible EAP layer is also by the end contact of electrode and rubberized fabric.Or the electrode contact of local is possible, or be possible in the whole length of rubberized fabric or at the whole electrode contact circumferentially of cylinder or roller, rubberized fabric is positioned on described cylinder or roller.The electrode contact of local can be fixing contact or slidingly contact.When the superiors of rubberized fabric are made up of EAP layer, described layer can thereon on side by with described upside Mechanical Contact and the matrix that can fully conduct electricity, i.e. so-called subtend part switch, and to be switched by the surface electrode be integrated in rubberized fabric on the downside of described layer.In the modification with electrode contact, the electrode that can contact multiple, separated from one another can be arranged on end face.

When MAP layer, contactlessly magnetic field can be applied to described layer, described magnetic field is through MAP layer.The both sides of MAP layer can or directly be close to MAP layer ground or arrange soft magnetic materials contiguously with MAP layer.According to pole shoe principle use, soft magnetic materials is used as the booster in magnetic field.The coil using magnetic layer and flow through by electric current in another modification.Magnetic layer is arranged in cylinder gap, such as impresses on the side in gap or roller gap, and coil is arranged on its other side.The both sides in gap refer to two sides be radially spaced apart from each other.Magnetic layer such as can be positioned on the side of blanket cylinder, and coil can be positioned on the side of counter-pressure cylinders, and described counter-pressure cylinders forms impression gap together with blanket cylinder.In the layout that coil is right, there is another kind of possibility, namely described coil is to encirclement cylinder gap and roller gap.Coil is to being preferably configured for the Helmholtz coil producing uniform magnetic field.If form two cylinders in gap and roller has the diameter be equal to each other, should elastic hardness being changed in the region in described gap, so utilizing unique coil can produce very large magnetic field for activating MAP material.The cylinder of two equal diameters or roller can be such as ink application roll and half tone roller or can be such as blanket cylinder and plate cylinder or can be such as blanket cylinder and impression cylinder.In conjunction with EAP material use described in be used herein to and arrange that electrode and the layout modification for contacting also are applicable to use MAP material in the meaning of remodeling.The electrode material of the conduction used when using EAP material must be substituted by soft magnetic materials when using MAP material.Such as with high concentration, soft magnetic granules can be added in described layer on two of a MAP layer side respect to one another.

Form and utilize functional polymer to change the cylinders of printing press cylinder dressing of component of character or printer roller roller shell not necessarily as the ground periphery of hectographic printing ink of constituent components, in this case cylinder or roller when rubberized fabric, but also can be liner or mat, described liner or mat are arranged in below cylinder dressing on cylinder or roller or roller shell, and described roller shell forms ink transfer cylinder periphery.Function polymerization can be such as the part of rubberized fabric liner, and described rubberized fabric gasket arrangement is below rubberized fabric.When liner, described liner comprises functional polymer, such as EAP material or MAP material, and utilizes described functional polymer to change the elastic hardness of liner.Consequent advantage is, separates and can be replaced when reaching the limit of wear, and also need not change liner at this and therefore change functional polymer through frayed outer cylinder dressing or roller shell and the liner be positioned at below it.Such as when replacing the rubberized fabric of wearing and tearing by also very new rubberized fabric, the functional polymer liner below the rubberized fabric being arranged in the wearing and tearing on cylinder is retained on cylinder.By described use, for one of rubberized fabric of multiple nonfunctional polymer and identical functional polymer liner reduce and replace component costs and operating cost.

Another further scheme relates to the compressibility by manipulation function polymers to alter component, and described component is equipped with described functional polymer.In described further scheme, described component also can be already described conveying cloth or rubberized fabric.Described rubberized fabric can have the compression layer be made up of the polymer foaming, and wherein, the polymer of foaming is the functional polymer of foaming.The functional polymer of foaming can be the EAP of foaming or the MAP of foaming.By using EAP material or MAP material in rubberized fabric, the compression layer of rubberized fabric is changed in its compressibility, and therefore can change compression distance under predetermined extruding force, or changes extruding force under predetermined compression distance.The compression layer comprising the functional polymer of foaming can be the part of the liner below cylinder dressing or roller shell, and in this case, described roller shell does not need to comprise the compression layer with functional polymer.Form that component by liner, the compressibility of described component can be changed by means of functional polymer.Rubberized fabric such as can have the compression layer of nonfunctional polymer, and the liner be arranged in below the described rubberized fabric on cylinder can have the compression layer of the functional polymer of band foaming.That Binding change elastic hardness has been carried out, to forming the possibility of contact surface and electrode and being also applicable to change compressibility in the meaning of remodeling to applying and changing the explanation of Electric and magnetic fields for the possibility of manipulation function polymer.Can be such as in the machine of electrofax work, provide the configuration changing compressibility by the machine construction of processing printable fabric.The machine of this electrofax work has conveying cylinder, and described conveying cylinder receives printed patterns and outputs on printable fabric in the second conveying gap in the first conveying gap.Realize printed patterns to be transferred on conveying cylinder in the first conveying gap under by the support of electric field.Conveying cylinder can cover conveying cloth or rubberized fabric, and described conveying cloth or rubberized fabric have the compression layer that is made up of functional polymer or be arranged on liner, and described liner has the compression layer be made up of functional polymer.In the first conveying gap, need the high compressibility of rubberized fabric, so that tolerance balancing and make surface pressing minimize.In the second conveying gap, need low compressibility in contrast, to realize high surface pressing.By correspondingly manipulation function polymer, on two conveying gaps, the compressibility of compression layer can be regulated independently of one another.At this, functional polymer is configured to MAP and has advantage and be, do not affect electric field by the magnetic field for manipulating MAP in the second conveying gap, described electric field is supported printed patterns to be transferred on conveying cylinder in the first conveying gap.But in principle in the described situation of the machine of described electrofax, also functional polymer can be configured to EAP.At this, can be guaranteed by the measure determined, in the first conveying gap for the electric field needed for hectographic printing pattern can not by the second conveying gap for activate compression layer EAP needed for electric field weaken.The top of compression layer and/or the integrated surface electrode of rectangular structureization belong to this measure.Another measure of integrated electrode is not needed to be the field parallel ground orientation of being carried by the electric field and first in the second conveying gap in gap.

Another further scheme relates to the change as cylinder dressing or the rubberized fabric of roller shell or the resilience of conveying cloth.Resilience is such numerical values recited for this reason, and namely how soon the material of component, in this case rubberized fabric rebounds when moving out from described gap in cylinder gap or roller gap, such as in described material press-in or flattening after impressing in gap.MAP as functional polymer is very well applicable to the change of resilience.Change about the intensity in the magnetic field be applied on MAP can change the loss modulus of MAP.Change the following time by changing loss modulus, MAP or the rubberized fabric being equipped with it need the described time again to have its initial shape after being pressed in cylinder gap or roller gap at MAP.Therefore, the trend of surface pressing changes in cylinder gap or moving out in region of roller gap.

In another further scheme, the thickness of component is the character that enough can change by means of functional polymer.By using electroactive polymer (EAP) and/or magnetic living polymer (MAP), can by electric field and/or magnetic field are applied to expect change character position on the thickness of modification layer.By using EAP material and/or MAP material, such as carry the flexible of cloth and/or compressible layer can be changed on its thickness, and under predetermined extruding force, therefore change contact zones width and the surface pressing of conveying cloth and other matrixes, such as printable fabric or clearer, or change surface pressing under the matrix of predetermined theory invades (supply, compression distance).But functional polymer is not only to be used as the adjusting device regulating continuously thickness, but also can be used as the switching device shifter be switched to by component in two switching states.Be in when being formed on the impression cylinder in gap, such as blanket cylinder when carrying cloth, two switching states can be that printing is started and printing stops.Printing is started and printing stops to be switched by the variable thickness of conveying cloth or the liner under being arranged on it.For by the example carrying the functional polymer of cloth or the functional polymer of liner to be used for step-less adjustment being the adjustment to the feeding of the printing degree of depth.When regulating printing degree of depth feeding, according to the thickness of printable fabric, the spacing between such as page Zhang Houdu adjustment conveying cylinder and the counter-pressure cylinders of cooperation.The thickness of conveying cloth or liner changes and can or carry out in conveying gap or impression gap, or circumferentially carry out the whole of conveying cylinder simultaneously only partly, such as.The Another application that the thickness caused by means of functional polymer changes is in the gap extending longitudinally transverse to print direction, such as to produce variable internal field by the array of electrode or such as produce local magnetic field by the array of coil.This can produce carries each little region of cloth for contacting with subtend part, such as ink application roll or printable fabric, to produce each printing points or printed patterns by this way from uniform ink layer.Another application is the unevenness compensating subtend part or conveying cloth transverse to print direction.Usually beat or other unevenness can be rotated along print direction compensation, such as, to make surface keep constant relative to the spacing of discontiguous write head, such as injection array or LED array by regulating.About the active material (functional polymer) for changing thickness possible configuration, with the possible contact of described active material and be applied on described active material field in, with reference to the explanation that the change in conjunction with elastic hardness and compressibility has provided, described explanation is also applicable to change thickness in the meaning of remodeling.

Another further scheme comprises the coefficient of friction on the surface changing component by means of functional polymer.Electric field and/or magnetic field are applied to the coefficient of friction that the layer be made up of EAP material and/or MAP material may be used for modification layer surface.This change can according to the material on layer surface by changing elastic hardness and/or surface roughness realization.Such as carry the superiors of cloth can by using EAP material and/or MAP material and being changed in the coefficient of friction of the described the superiors by electric field and/or magnetic field being applied on described material.Concrete application example is as follows: the surface of conveying cloth should have high as far as possible coefficient of friction for the rotary actuation realized by friction by the roller clinged on conveying cloth, however have for the interaction of cleaning element for little as far as possible coefficient of friction.By means of the functional polymer of conveying cloth, described functional polymer surface can be converted alternatively in the coefficient of friction on described surface on the high coefficient of friction for roller and the low coefficient of friction for cleaning element.

Changing the component comprising functional polymer of character by functional polymer is not can be only conveying cloth or rubberized fabric, but instead can be that forme or printing are touched version and also can be arranged in the liner below this forme yet.It is also possible that described component is liner, such as impression cylinder cylinder dressing below printable fabric.
