Abstract

Staple (optionally crimped) fibres formed during the conversion of a tow of continuous synthetic e.g. cellulosic such as cellulose triacetate, polyacrylic, polyamide, polyester, polyolefin, vinylic, filaments, by passage between cutting and anvil rollers in a Pacific Converter, are "debonded" or separated by subsequent passage through the nips of successive roller pairs the distance between which is preferably slightly less than the fibre length. Each pair comprises an upper roll with a hard e.g. steel, helically threaded surface mating with a cushioning roll having a resilient e.g. rubber, surface and the second pair is driven at the faster speed; some fibres are gripped between flat (helical) lands in the first pair (but are not gripped between the second pair) and other fibres are passed without gripping in the helical troughs between the lands in the first pair but are gripped at the second pair, with the result that some fibres are moved longitudinally relatively to other fibres.
