Abstract

A stretched fiber band is deposited in a can, located in the filling station of a can exchanger of a draw frame, by means of a turntable. The rotational axis of the turntable exhibits an equal to or less than distance from the rotational axis of the can exchanger than the distance from the center point of the can found in the filling station to the rotational axis of the exchanger. Upon the substitution of the filled can by an empty can held in a ready-state position, the operation of the can exchanger on the rotation of the turntable is designed in such a manner, that the fiber band is deposited into the full can exiting the filling station, until this can leaves the zone of the turntable. The fiber band is then deposited into the empty can which has been brought into the filling station II, as soon as this empty can reaches the zone of the turntable. To enable this procedure, the empty can to be delivered to the filling station is temporarily moved with increased speed, and the spatial interval between the empty can to be delivered to the filling station and the full can which is leaving the filling station is reduced.
