Abstract
An apparatus consisting of a stuffer box crimping device of a conventional type with a cooling device immediately following thereafter and designed as a sieve drum under a suction draft. The dense crimped parcel, conducted to the sieve drum surface from the crimping chamber optionally by way of a chute is seized by the cooling air, thereupon cooled, and continuously transported. The thus set crimped structure can then be deposited without problems onto an endless belt arranged at a spacing therefrom.
