Open end spinning apparatus |
摘要 |
An open-end spinning device wherein yarn is produced in a spinning compartment and withdrawn therefrom by yarn-withdrawal rollers and a winding device. The yarn storage device is interposed between the yarn-withdrawal rollers and the winding device. A knock-off motion is positioned between the spinning compartment and the yarn withdrawal rollers for producing a signal responsive to changes in tension in the yarn. THe yarn storage device includes a roller storage which is driven in a forward direction for accumulating a supply of yarn that is to be fed to the winding device. The roller storage can also be rotated in a reverse direction for withdrawing yarn therefrom during a piecing operation. A yarn gripper is provided for gripping the yarn upon a change in tension in the yarn.
