Abstract
A one step method for integrally attaching a backing cover to a universal fiber-reinforced backing before curing. The manufacturing method includes attaching a porous cover to a reinforcement configuration of fibers and adhesive before curing. The cover is pressed against the fibers and adhesive for compressing, collapsing, and flattening the ends of the stitch portions. The compressing and collapsing actions cause adhesive and fibers to be directed toward and forced into the porous cover. Adhesive and reinforcement fibers provide an integral attachment of the cover to the reinforced backing before and after curing.
