Abstract

A yarn false twist crimping machine which comprises a processing frame which mounts the yarn processing components, a creel for mounting the yarn packages, and a take-up frame which is laterally spaced from the processing frame on the side thereof opposite the creel so as to define an operator aisle therebetween. An elongate heater is mounted to the take-up frame and an elongate cooling plate is mounted to the processing frame, and a false twist unit is mounted to the processing frame below the outlet end of the cooling plate. The yarn is guided from the creel in a generally planar arrangement across the operator aisle and to a first yarn feed system which is mounted on the take-up frame. The yarn then advances through the heater and cooling plate to the false twist unit and so as to loop back through the plane defined by the yarns being fed from the creel. Two such machines may be mounted in a mirror image relationship so as to define a service aisle which is bordered by the take-up frames of the two machines, thereby providing for the efficient servicing of the take-up devices of the two machines.
