ABSTRACT:
A sliver coiling apparatus has a rotatably supported coiler head including a sliver discharge opening travelling in a circular path upon rotation of the coiler head; a first drive for rotating the coiler head; a support for positioning a coiler can underneath the coiler head such that a central axis of the coiler can is eccentric relative to the circular path; a second drive for moving the support for removing a full coiler can from under the coiler head and positioning an empty coiler can thereunder; a position sensing arrangement for emitting a signal when the sliver discharge opening is situated on an inner half circle of the circular path. The signal is applied to the second drive for energizing the second drive to displace the support when the sliver discharge opening is situated on the inner half circle for effecting rupture of the sliver.
