<p>Apparatus for transporting knives, sockets, holders and analogous devices for severing, supporting, transferring and/or otherwise manipulating rod-shaped articles which constitute or form part of smokers' products has first and second disks which are rotatable about parallel axes and carry sets of levers each pivotable about an axis which is parallel to the axes of the disks. Each lever of one disk is coupled to a lever of the other disk by a crank unit one pin of which carries a tool. One of the disks is driven and transmits torque to the other disk by way of the levers and crank units whereby the crank units orbit and their pins hold the tools against any change of orientation. Stationary cams have congruent grooves for roller followers which are provided on the levers of the first and second disks, and the cam grooves are configurated in such a way that the cams can reduce or increase the absolute speed of movement of crank pins by moving the pins toward or away from the axes of the respective disks. The tools can transfer rod-shaped articles from a conveyor which transports the articles axially to a conveyor which transports the articles sideways, or vice versa. Also, the tools can constitute sockets which prop spaced-apart portions of a continuous tobacco or filter rod during severing of the rod. The severing mechanism can employ a second apparatus which is mirror symmetrical to the apparatus whose crank units support the sockets, and the tools of the second apparatus include rotary knives cooperating with successive sockets to sever the rod at desired intervals.</p> |
