WATER-PERMEABLE DRUM FOR THE HYDRODYNAMIC NEEDLING OF WEBS OF TEXTILE MATERIALS, AND METHOD FOR THE PRODUCTION OF SAID DRUM

摘要

A water-permeable drum assembly for the hydrodynamic needling of textile materials in order to reinforce and structure the textile materials or refine the surface thereof has an intrinsically stable sieve drum provided with apertures and an outer tubular sieve-type cloth made of intersecting wires and pulled across and fixed to an outer surface of the drum. The outer sieve-type cloth has a coating that stabilizes intersections of the wires.
