Friction spinning apparatus.

摘要

The mask sleeve (6) within the perforated roller (2) of each spinning unit of a multi-position friction spinning machine is adjustable independently of that of the other spinning units to move the suction slot between extreme positions (7a and 7b) in which an edge of the slot crosses from one side of the friction spinning nip to the other. Adjustment is effected by means of a rotary adjuster (19) engaging a bifurated end (23) of a carrier (15) which is itself adjustably fastened (by way of a clamp bolt 17) with respect to the masking cylinder (6). 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.
