Device for interrupting the feed of a roving to drafting units of a spinning machine

摘要

The invention relates to a device for interrupting the feed of a roving in drafting units of a spinning machine, in which, in the event of a thread break, the roving is clamped by means of a clamping segment on the entry side of the drafting unit and is no longer transported any further. In addition, the pair of delivery rollers of the drafting unit is assigned a suction appliance which sucks off the part of the roving transported further by the drafting-unit rollers located downstream of the clamping device.
