Abstract (en)

[origin: JPH01124643A] PURPOSE: To provide a method for continuously and efficiently crimping thermoplastic filaments by discharging a heating medium out of all parts of a filament bundle, held by 2 ring-shaped walls as the air passages on a wheel. CONSTITUTION: This method continuously crimps thermoplastic filaments by an apparatus, equipped with 2 ring-shaped walls as the air passages apart from each other on a wheel 5 in a stuffing chamber 3, into which a filament bundle 2 is blown by a jet nozzle in a tangential direction over the wheel. The crimped filament bundle is delivered to a suction drum as the transfer element in a delivery zone C.
