A pivoted stop motion particularly adapted for each of a plurality of ends of sliver or the like is operatively associated with a rotatable guide for sliver having little tensile strength to stop the drawing frame if an end of sliver breaks or becomes slack. An electrically charged contact rod extends over a row of pivoted sensors perpendicularly to the path of the sliver, the several ends of which are separated from each other by discs fixed to a rotatable shaft. Breakage of an end of sliver causes its corresponding sensor to engage the contact rod to stop the machine.
