ABSTRACT:
For the monitoring of the lap formation in the case of delivery bottom rollers of drafting units, sensing elements are provided which, when a lap is formed, as a result of the enlarged diameter at the delivery bottom roller, are moved radially away from this delivery bottom roller. The sensing elements are used as switching elements for an electric circuit to which a number of sensing elements, and preferably all sensing elements of the spinning machine, are assigned. When a lap is formed, the assigned electric contact is opened by the shifting movement of the sensing element so that the electric circuit is interrupted. The interruption of the electric circuit causes the triggering of a signal.
