ABSTRACT:
A coiling device for depositing sliver in a canister has a rotary cage having an axis of rotation; a mechanism for rotating the cage; an inlet opening through which the sliver is introduced into the cage; an outlet opening in the cage eccentrically thereof for discharging the sliver in a path orbiting about the cage axis. There is further provided a first calender roll supported in the cage; a drive mechanism connecting the cage with the first calender roll for rotating the first calender roll about its longitudinal axis upon rotation of the cage about the cage axis; a second calender roll supported in the cage on a pivotal shaft mounted in the cage and spaced from the second calender roll. The second calender roll is urged against the first calender roll for generating a clamping force. The second calender roll and the pivotal shaft form part of a pivotal unit. The two rolls constitute a cooperating calender roll pair between the inlet opening and the outlet opening for drawing, by means of the clamping force, the sliver through the inlet opening and advancing it through the outlet opening. The axis of the pivotal shaft is so oriented in the cage that the centrifugal force generated by the rotation of the cage and exerted on the pivotal unit has a sole direction of action which leaves the clamping force unaffected.
