A removal element which is mounted rotatably on a driven support is driven by a cam mechanism comprising a fixed double-cam wheel 53 having two superposed cams 27,28 on one side and two sets of followers 24a,24b,25a,25b,26a,26b which are mounted by means of a support element 51 on the drive shaft 6 of the removal element or a bearing shaft 50 which is coupled to the shaft 6, and due to positive engagement with the two cams 27,28 during rotation of the support 1 ensure the positive motion of each removal element over its entire path of revolution. For the purpose of a simple and compact construction of the labelling station, the drive or bearing shaft 50 terminates before the plane in which the first cam 28 nearer said shaft 50 is situated and the followers 24a,24b which are assigned to the other, second cam 27b are mounted on a bridge member 52 which is situated outside of the said plane and is borne by the followers 25a,25b,26a,26b of the first cam 28. Because of the shaft-less central space 56 between the followers 25a,25b,26a,26b in the region of the first cam 28, this cam may also be fully developed and reach into this free space 56. …<IMAGE>… |
