ABSTRACT:
A sliver coiler for depositing a running sliver into a coiler can includes a driven roller pair including two cooperating rollers arranged for advancing the sliver passing therebetween in a feed direction; and a sliver trumpet supported upstream of the roller pair as viewed in the feed direction and having a passage through which the sliver runs. The sliver trumpet has a first position in which the sliver exit of the passage immediately adjoins and faces the roller pair of a second position in which the sliver exit is at a greater distance from the roller pair than in the first position. The coiler further has a coiler head arranged downstream of the roller pair and arranged for receiving the sliver and forwarding the sliver into a coiler can; a drive for displacing the sliver trumpet between the first and second positions; and a clamping arrangement for grasping the sliver at a location between the sliver entrance of the sliver trumpet and the roller pair. The clamping arrangement has a clamping position in which the sliver is grasped thereby and an open position in which the sliver is released.
