Document Type and Number:
Japanese Patent JPH0669405
Kind Code:
B2
Abstract:
A method of forming a chain of meandering or zig-zag coupling elements (E) for slide fasteners comprises dividing or bifurcating a continuous length of substantially cross-sectionally circular monofilamentary material (M) axially into identical halves (10a, 10b) of substantially semi-circular cross-section immediately prior to introduction to a forming apparatus (12). The identical halves (10a, 10b) may be provisionally joined together to provide a cross-sectionally circular monofilament (10) and divided back into respective halves (10a, 10b) immediately prior to formation thereof into respective rows of coupling elements (E) for slide fasteners.
