Abstract
Apparatus for spinning yarn from roving including a spinning frame with spinning units arranged thereon. The roving to be drawn is fed from a common double-roving bobbin to each of two neighboring spinning units, further referred to as spinning units pair. At least one stopping device is assigned to each of the spinning units of the spinning units pair, to stop and release again the roving feed to the two drawing frames of the respective spinning units pair. The purpose of the stopping device is to reduce the loss of roving and to avoid the danger of yarn lapping on the drawing rollers. The stopping device can be actuated by each of two yarn break sensors of the spinning units pair for the simultaneous arrest of the roving. In a second embodiment a yarn-setting carriage is provided on the spinning frame to correct a yarn break, such correction occuring only when all correction hindering conditions are absent.
