Abstract

A mat consists of filament loops, which are irregular in shape. The loops are produced through the winding in coils of several thermoplastic filaments with large loop openings. The loops are joined to each other by their intersecting parts. The process for mfg the mat involves a continuous production of several filaments at a distance from each other in the longitudinal and lateral directions. The filaments are produced by means of extruding a synthetic thermoplastic resin, e.g. PVC, out of a T-shaped nozzle unit.
