Abstract
An apparatus and method that apply retention aid material to an inner diameter of an apertured part, such as a washer, a collar or the like. The method can include: moving a apertured parts linearly, optionally horizontally, along a conveyor, each apertured part defining an aperture and including upper surface and opposing lower surfaces with an inner diameter surface therebetween; dispensing a liquid retention aid material from a dispenser so that the material engages and/or spatters against the inner diameter surface as the apertured parts move linearly, optionally horizontally, along the conveyor; and curing the material to join it with the inner diameter surface, thereby forming a resilient retention aid projection extending inward from the inner diameter surface. The apparatus can perform the method, which can include seeping the material under the lower surface to form a seepage portion. An apertured part with a retention aid is also provided.
