METHOD AND APPARATUS FOR MANUFACTURING THERMOPLASTIC MATERIAL WITH LUDER SURFACE

摘要

In a method and apparatus for making a pile-surfaced thermoplastic material by a tack-spin technique the laminate of backing web and adhered pile is hauled off from the heated drawing surface over a rod or bar which fixes the point at which the laminate separates from the heated drawing surface and which directs cooling fluid from an aperture in the rod or bar and onto the back of the backing web and into the fibril-forming area.
