Abstract
In a sliver conveying and depositing device, the sliver is guided from the carder through a draw frame to a can coiler. A first deflection device mounted on the free end of a pivotable arm is arranged between the last driven roller pair of the draw frame and the can coiler. The sliver is guided across the first deflection device and the arm exerts a counter pressure onto the sliver for maintaining sliver tension. The first deflection device is displaceable for compensating the sliver length between first and second end positions, wherein signal transducers emit a signal when the first or second positions are reached. The speed of the can coiler drive is changed when a signal is received from the signal transducers, wherein a time interval elapsed since the last signal has been received from one of the signal transducers is taken into account for changing the speed.
