in winding machines , known roll systems are used that contain a number of freely rotatable roll segments , which are situated next to one another face to face and mounted in a manner that enables them to move perpendicular to their rotation axis . according to the invention , the roll segments are mounted so that only one respective face is mounted on a bearing journal , which is fastened in an interspaced manner to a bearing plate that can move perpendicular to the rotation axis . an annular slot is fashioned in at least one inner side of each bearing plate , and the end of a roll segment can rotate without touching inside this annular slot .
