ABSTRACT:
A plurality of separate synthetic plastic fibers are advanced through respective discrete guide passages of a housing towards a crimping chamber. The housing is provided with bores for supplying a stream of hot gas into each of the passages to thereby plasticize the fibers. Thereafter, the fibers pass into the crimping chamber, where the gas entering this chamber is withdrawn, so as to crimp the fibers. The housing is provided with another passage, which connects the opposite end of the crimping chamber with the exterior of the housing. This passage receives the fibers in crimped condition and allows them to be wound onto takeup spools individually.
