The rotating cam disk 44 acts on the roller 43 (FIG. 2) seated on the axis of the bracket 37, the console 37 begins to move forward, and this with its sprung, between the teeth of the disk 29 engaging pawl 35, the disk 29 of the drum set in rotation the rotation of the drum, the pawl 35 goes out of engagement with the teeth of its disk 29 and shifts until it falls into the gap between the following teeth, in this way the The rotary movement of the cam disk 44 is converted into a periodic rotation of the drum. The console 37 is in the period where the pawl 35 comes out of engagement with the tooth of the disc 29 by the on her attached coil spring 40 is withdrawn, and when the cam disk 44 by means of the roller 43 the disk pushes forward, the helical spring 40 softens the impact of the pawl 35 against the tooth, whereby a smooth transition of the same from one tooth of the disk 29 to the other is ensured.

As a result, the displacement of the device 5 for the piece-wise output of the rod elements with the Rotation of the drum and the storage container 2 synchronized

During the oscillating movement of the bunker 2, the rod elements are grasped by the plates 14 and by these poured into the fixed part 20 of the storage container 2. From this part, the rod elements pass into the channels 4. Since these channels 4 are inclined, the rod elements move in them up to the point at which the device 5 is located. During the displacement of the device 5, ie the bar, its inclined slots 23 (Fig. 1) piece by piece capture the rod elements from the channels 4, which then pass through these slots 23 and into the remaining part of the channel 4 and then from these channels in the additional guide tubes 21 arrive. The rod elements pass from these guide tubes 21 into the bores 68 arranged in the bar 47, specifically with the same mutual spacing in relation to one another as the holes 32 are arranged in the radial row A of the disk 29.

At the moment when the ball 49 of the fixing catch engages in the bore 48 of the disk 29, the drum stops for a certain period and the radial row A of the holes 32 of the disk 29 is coaxially aligned under the bores 68 of the bar 47 with the ends of the tubes 21 set. After this, all rod elements from all bores 68 simultaneously enter all holes 32 of the radial row A and enter the tubes 7, through which the rod elements move in an oriented position and via the holes 33 of the lower disk 30 into the coaxially arranged holes 55 ( Fig. 7) and 66 of the cassette 34 got into it.

In this way, a number of holes in the cassette 34 can be filled with rod elements at the same time take place.

When all the rod elements are in the holes 32 of the radial row A , the drum begins to rotate until the ball 49 of the fixing notch of the bar 47 moves the drum into the coaxially aligned position of the bores 68 of the bar 47 with the following row A. the holes 32 of the disc 29 has fixed again.

If the cassette 34 is filled with the rod elements, it is removed without stopping the rotating drum, the projection 65 (FIG. 6) of the plate 62 being grasped with a finger and pushed towards the body, ie in the direction indicated by arrow C. Here, the holes 66 (FIG. 7) are partially displaced with respect to their holes 55 of the base body 53, whereby they clamp the rod elements. The cassette 34 (FIG. 1) is then removed by pressing it down slightly, the balls 58 leaving the annular groove 52 of the rods 51.

The cassette 34 removed with the rod elements is then turned with the plate 62 pressed on and places it in the inverted position on one with perforated holes, but not in the figure shown, the same shape as the cassette having a die of a press, whereupon the The finger from the projection 65 of the plate 62 releases it by being under the action of the spring 67 (FIG. 5) in the Starting position moves the bar elements releases The bar elements released fall into the holes of the Die, while the cassette, which has been freed from the rod elements, is again attached to the lower disk 30 attached to the drum. A rubber pad is placed on the bar elements that have remained in the die, after which the press plunger is inserted Movement displaced which when moving with its rod with holes on the rubber pad if this pushes against the die and goes back

Thus, the rod elements are hammered into the Cushions in the whole group at the same time. Then the finished rubber cushion with the rod elements removed from the die, whereupon it is ready for another work cycle.
