PROCEDURE AND APPARATUS FOR CONTINUOUS PRODUCTION OF CORRUGATED/UNDULATED SHEETS IN A WINDABLE WEB; WINDABLE THERMOPLASTIC WEB WITH TRANSVERSE CORRUGATIONS/UNDULATIONS

摘要

The wave or zigzag shape of continuous ripple thermoplastic material sheet material production are arranged to its horizontal axis and provide direction, or advance, when the web is by cooperating the cylindrical hole portion for being equipped with the suction unit that slot is connected to and a drawing-die between its moulding cylinder. The corrugated plating is windable, this is conducive to apply, in storage and transportation.
