ABSTRACT:
An apparatus for depositing sliver in a coiler can includes a pair of cooperating pressure rolls; a coiler head rotating about a rotary axis and having a sliver inlet for receiving sliver from the rolls and a sliver outlet situated eccentrically with respect to the rotary axis for discharging sliver from the coiler head; a movable coiler can platform disposed underneath the coiler head for receiving an upwardly open coiler can thereon; and a severing device for severing the sliver at a location downstream of the rolls as viewed in a direction of sliver run. The position of the sliver outlet on its circular path, the position of the platform in its motion path and the running length of sliver are determined. Based on these data rotation of the coiler head is stopped when the sliver outlet is in a position corresponding to a predetermined total sliver quantity in the coiler can less a trailing terminal sliver length portion, the platform is moved in a stopped state of the coiler head such that the coiler can outline is out of vertical alignment with the coiler head, whereby a trailing length portion is deposited in the coiler can and a part of the trailing length portion hangs over a top wall edge of the coiler can.
