Abstract
A device for interrupting feed of a roving on a drawing frame, having a feed roller pair, e.g., a powered bottom roller and a top roller tensioned against the bottom roller by springs, includes a clamp for lifting the top roller away from the bottom roller and clamping the roving against the circumference of the top roller. The clamp is disposed on a lever pivotable about an axis parallel to the axes of the feed roller pair and is shiftable with respect to a clamping edge, in the feed direction of the roving, toward the circumference of the top roller. The clamp includes a tongue which initially engages in the nip between the rollers and a portion having a toothed profile which cooperates with the clamping edge by engaging the roving.
