Setting a procedure on air jet spin device, including main distortion zone having stretching unit and a pair of delivery rollers, comprises propelling the delivery rollers against their normal acting rotating system

摘要

A stable fiber assembly (2) is placed at the beginning of the distortion zone (11) and finely spun fiber end piece (1) is located at the beginning of the assembly against its normal operating system. The end piece is led back into the distortion zone. The pair of delivery rollers (9, 10), preceding the rollers (5, 6) of drafting equipment (4), is propelled for retreating the fiber assembles against operational direction of rotation. A reversible driving motor (15, 16) causes the propelling.
