ABSTRACT:
A first sliver in an exhaust can (2F) is introduced and held in a recess (38a) of a sliver piecing unit (38) while gripped by a sliver gripper (34). The first sliver is severed by the displacement of the gripper (34) away from the recess (38a) so that a trailing end of the first sliver is formed in the recess (38a). Next, a second sliver in a reserve can (2B) is introduced and held in the recess (38a) in the same way as for the first sliver and a leading end of thereof is formed in the recess (38a) so that the sliver ends overlap each other. The piecing operation is carried out on the overlapped sliver ends in a known manner.
