ABSTRACT:
The invention concerns a feed device for feeding rod or striplike material, the device having two or more feed members which are arranged to lie behind one another along a feed path of the material. Each of the feed members carries a plurality of grippers arranged at equal angular intervals around a central axis of the feed member and is connected with a gearing which imposes on the feed member a rotational motion about its axis and, simultaneously, a circular motion about a fixed axis parallel with its own axis. The arrangement is such that said rotational and circular motions are coordinated so that the grippers of each of said feed members describe a trochoidal path which includes a substantially straight-line section along the feed path. Devices are provided for the automatic actuation of the grippers during their sweep through the straight-line section and the motion of the two feed members is coordinated so that the grippers of one feed member engage the material alternately with the grippers of the other feed member with an overlap in time to provide continuous advancement of the material.
