ABSTRACT:
An apparatus and method for interrupting delivery of sliver to a spinning frame for spinning sliver into yarn and winding the yarn onto a spindle utilizing a sliver stop motion. The sliver stop motion is positioned on a respective drafting system of the spinning frame. The sliver stop motion is mounted to the spinning frame so as to overlie the back drafting rolls for stopping the motion of sliver being drafted by the back drafting rolls responsive to a break in yarn being wound onto the spindle. The stop motion includes an elongate pivoting member which is pivotally mounted to a frame mounting member. The frame mounting member is pivotally mounted to the spinning frame. At the stop motion's proximal end, a yarn contact member extends outwardly therefrom so as to underlie and slidably contact yarn being directed to the respective spindle. A sliver comb is connected to and extends outwardly from the distal end of the elongate pivoting member so as to overlie sliver being drafted by the back drafting rolls. Therefore, during a break in yarn being wound onto the spindle or otherwise, the yarn contact member responsively moves upward from the broken yarn and the sliver comb responsively moves downward to engage the sliver during pivotal movement of the elongate pivoting member. The sliver engaged by the sliver comb is responsively broken under the forces of the continuously operating drafting rolls and the retention of the sliver by the sliver comb.
