Abstract
Abstract The invention is specifically concerned with an improvement in the process of manufacturing reinforced materials. The reinforced materials are conceived to include a wide variety of materials, the most notable being high density compressed gaskets. The improvement comprises mixing a cut solid (generally a cut fiber) with a body material to produce the reinforced materials. The solid is cut into particulates of highly variable size, the range in the size of the particulates being adjusted to optimize the characteristics of the resulting reinforced material. The cut solid is produced utilizing comminuting machines previously used for the recycle of waste products.
