Method for restoring the spinning process after a failure of the automatic bobbin change or in the change of yarn linear density on open-end spinning machines and devices for carrying out this method

摘要

In the event of a failure of an automatic bobbin change on an open-end spinning machine (1), an auxiliary yarn (19) to be drawn off from a supply bobbin (18) is wound onto each bobbin tube (10), where an interruption of the spinning process has occurred during the automatic bobbin change and on the surface of which no yarn is available for piecing, and is severed from the supply bobbin (18), and piecing is carried out at the spinning station by means of a piecing unit (8) or by hand.
