ABSTRACT:
A device for interrupting the feed of a roving to drawing frames of a thread spinning machine of the type wherein each drawing frame comprises a plurality of pairs of upper and lower drawing rollers, of which the lower drawing roller, located on a roving in-feed side of the drawing frame, is provided with a clamping segment for interrupting the roving feed in a released position thereof in response to a broken-end detector, which monitors the presence of a spun thread, is improved by the provision of a suction device, associated with the drawing rollers on a thread formation side of the drawing frames, for collecting rovings present in a drawing frame when the roving feed thereto is interrupted. In accordance with a perferred embodiment, the suction device comprises suction tubes which are mounted for movement away from the drawing rollers and lockable in respective operating and nonoperating positions. According to another feature, the broken-end detector is mounted to an end of the suction tubes which face a drawing roller, which is downstream-most in a direction of the roving feed.
