ABSTRACT:
Textile strands are compressively crimped by propelling them lengthwise, as by a fluid jet, into a rotating cylindrical chamber having a foraminous surface. Rotation of the chamber aids in collection and temporary retention of the crimped strand until it is withdrawn therefrom at the leading edge of the strand accumulation after about half a revolution. The crimped strand is withdrawn between an edge of the chamber and an adjacent solid surface rotating therewith, as by conical rolls.
