Abstract
A winding station for webs comprises a plurality of knives disposed side by side and which are laterally displaceable along the width of a web to predetermined positions for slitting the web into a plurality of narrower webs. A guide roller is disposed downstream of the knife and a plurality of pairs of winding frames are disposed in at least two rows in a staggered relationship on opposite sides of the guide roller. The winding frames are laterally displaceable into positions corresponding to the positions of the knives by means of servomotors. The winding frames bear projecting chucks for receiving winding spools thereon and gripper cones over the winding chucks which are expandable radially by axial displacement. A program control effects the positioning of the winding frames to align the gripper cones with the knives. A program control utilizes the information of the sensing of the lateral position of the knives for first effecting the displacement of at least one winding frame of each pair to correct the position corresponding to the associated knives and thereafter effecting the displacement of the other winding frame of each pair against the one winding frame until the winding spool that is to be mounted is gripped by the axially moving and simultaneously expanding gripper cones. As a result of this movement, the lateral position of the gripper cones for some pairs of the winding frames are shifted off center.
