摘要

Process for the production of light-gauge continuous strip from a bundle of crimped continuous filaments, characterized in that it comprises decomposing the curls of the bundle of continuous filaments; passing an advancing bundle of continuous filaments of decomposed curls through a first spreader stage and extending the bundle to a width approximately 2 to 4 times greater than the width of the bundle immediately before its curls decompose; passing the bundle through a second extender stage and extending the bundle to a width of approximately 2 to 4 times greater than the width after the first spreader stage, to thereby form a web having an average web space of air per filament at least 5 times greater than the average diameter of the filaments of the beam.
