Abstract
METHOD AND APPARATUS FOR MAKING A BRUSHING TOOL
Abstract of the Invention A method is disclosed for making a brushing tool having a hub and a plurality of bristles extending from the hub. A mold defines a cavity which is divided into a closable mold cavity and a bristle cavity. At least one bristle locating pin is disposed within the bristle cavity.
At least one bundle of bristles is inserted into the bristle cavity adjacent to the at least one bristle locat-ing pin so that one end of the bristles is disposed within the mold cavity. The mold cavity is then closed so that the ends of the bristles within the mold cavity are gener-ally clamped together near the interface of the mold cavity and the bristle cavity. A thixotropic material in liquid form is injected into the mold cavity so that a portion of each bristle disposed within the mold cavity is surrounded by the thixotropic material. When the thixotropic material hardens, the portion of each bristle on the mold cavity becomes embedded in the hardened material, the hardened material thereby forming the hub of the brushing tool. In a preferred embodiment, the method is applied to a rotary brushing tool having a central hub and a plurality of bristles extending from the hub.
