Abstract
In a method for manufacturing a web of a ground covering having a web of pile fabric forming the upper side and cushion elements attached to its underside in grating-type configuration, in order to simplify the manufacturing process, plastic agglomerates corresponding to the cushion elements are produced from a pasty plastics material from which an elastomer is formable by curing, and are deposited in grating-type configuration on an endless conveyer belt; first a reinforcement web with openings therein and next the underside of the web of pile fabric are then placed on the plastic agglomerates such that the plastics material penetrates the openings in the reinforcement web and wets the underside of the web of pile fabric; the plastics material is subsequently cured by heat treatment and the web of pile fabric, the reinforcement web and the cushion elements are thereby firmly bonded to one another.
