ABSTRACT:
Method for aspirating and propelling waste yarn into extruder or molding machine which comprises using a forwarding jet or yarn aspirator to feed a created wad of yarn into a hopper feeding pellets to an extruder or molding machine or the like, the operation being further characterized in providing and using a hood extending into the hopper to protect the wad until it can be picked up within the pellet mass flowing downwardly over and around the provided hood.
In one embodiment of the method a godet roll is used, powered by a motor, for feeding the yarn to the aspirator at a controlled, desired speed. In a modification of the method, once the wad is being taken into the pellet mass and is being drawn by the extruder screw or by other means feeding a molding machine, etc., the air to the aspirator can be shut down in part or totally.
