METHOD OF FORMING A CHAIN OF COUPLING ELEMENTS IN MEANDRO FOR ZIPPER CLOSURES.

摘要

A METHOD FOR FORMING A CHAIN OF ZIG-ZAG COUPLING ELEMENTS (E) OR SINUOUS FOR ZIPPER CLOSURES, INCLUDES THE DIVISION OR BIFURCATION OF A CONTINUOUS LENGTH OF MULTIFILAMENTARY (M) SECTIONAL MULTIPLE TRANSVERSAL CIRCULAR MIRROR 10A, 10B) OF SUBSTANTIALLY SEMI-CIRCULAR CROSS SECTIONS, PRIOR TO THE INTRODUCTION TO A TRAINING DEVICE (12). THE IDENTICAL HALF (10A, 10B) MAY BE PROVISIONALLY UNITED TOGETHER TO PROVIDE A SECTIONALLY CROSS-CIRCULAR MONOFILAMENT (10), DIVIDED INTO THE RESPECTFUL HALF-MIDDLE LAYERS (10A, 10B) COUPLING ELEMENTS (E) FOR ZIPPER CLOSURES.
