ABSTRACT:
The mask sleeve within the perforated roller of each spinning unit of a multi-position friction spinning apparatus is adjustable to move the suction slot of that roller between extreme positions in which an edge of the slot crosses from one side of the friction spinning nip to the other. Adjustment at each spinning unit is effected independently of the various other units of the machine by means of a rotary adjuster engaging a bifurcated end of a carrier which is itself adjustably fastened (by way of a clamp bolt) with respect to the masking cylinder. The adjuster and the carrier are outside the machine and allow adjustment of the positioning of the slot deep within the spinning unit for fine tuning purposes.
