Patent ID: 7318254

Claim:
A sliver conveying and depositing device to be connected to a carder, wherein a sliver exiting from a carder exit passes through a draw frame comprised of at least two driven roller pairs and then reaches a can coiler, wherein the draw frame has a main drive for the at least two driven roller pairs and a regulating drive for a last one of the at least two driven roller pairs in a sliver conveying direction; the device comprising: a first deflection means arranged between the last one of the at least two driven roller pairs and the can coiler; an arm that is pivotable about a pivot axis wherein the first deflection means is arranged at a free end of the arm; wherein the sliver is guided across the first deflection means at a deflection angle; wherein the arm exerts a counter pressure onto the sliver for maintaining a sliver tension; wherein the first deflection means is displaceable for compensation of a length of the sliver and has a first end position and a second end position; signal transducers for emitting a signal when the first end position or the second end position of the first deflection means has been reached, respectively; means for changing a speed of a can coiler drive when one of the signal transducers emits the signal, wherein a time interval elapsed since the last signal has been emitted by one of the signal transducers is taken into account for changing the speed; wherein two of the signal transducers are arranged slightly displaced relative to one another for detecting the first end position and for detecting the second end position, respectively.
