The object of the present invention is to on the one hand the danger of this work process «axuuro · and from others the performance of the Hasefci-Re to. increase. To solve this problem, a Haschine dear- mentioned type of the invention -proposed, that the "dssr as Yerssh-sfefiegia" is the same as liedesixalter bam is trained for dan food. are.

In the event of a further spring chamber, the preacaakel is fork-shaped and the fork, in a deflected state, engages in slots in a lower counter-frat / or in the work surface. In the case of a machine with a goal push finger, it is very advantageous that all fights or groups. daron geseinsia adjustable «iad.

In a machine, there is at least one direction of light and a completely additional yorechub limitation device, the latter being formed from a lockable drag seal as well as two separate elements that can be defeated by the material to be cut, in the direction of advance of which there is a spacing from one another very kmäßig that the SehXeppa & beat over a rope pull or the like.

As soon as the distance stop at the rear in the suction direction has reached the Kleaa stop, it has to use it, if it is released, with further Hk & movement. The load is raised via the cable.

According to another embodiment of the invention, in a machine with at least one viewing light direction and a door thrust limiting device that interacts therewith, the latter also has a lockable drag stop and two kit that end together bit the material to be sliced movable spaced from one another in its gate thrust direction The drag stop is connected via a cable pull or the like with a tensioning and sliding weight and is arranged between the two spacer links.When the drag stop is freely movable, it rests against the front spacer connector in the delivery direction due to its constant weight load.

aessfir are assigned. It goes without saying that the two KaS rods extend in the opposite direction to the infeed direction, ie they end with the operator. If there are several directional lights arranged offset in the feed direction, the ** i * i> 0 of the hatred sticks can be increased so that a scale begins with each calibration light. Usually one works bit to the scale beginning as RichtXicht and the feed limitation iehtSBs. The cut edge is determined and the length of the material to be cut measured in the direction of flow can then be read on the first scale. However, tills are also conceivable in which, despite the completely withdrawn transport device for the material to be cut, the latter protrudes too far beyond the light in the feed direction, so that when using the feed limitation device too much would be cut off and the loss of material would be too high. The bit of the beginning at the cutting knife is worked into this pail. KaSstab, which has a larger length with the distance between the viewing light and the cutting knife. As mentioned, the cutting edge is aligned with the cutting knife and the Yorsehubbegrsnzungeeinrichtung does not come into operation in this case *.

The end of the stack aligned in this way or the rear part of a single file in the figure 4 is placed on the rear stop surface 5 of the feed fingers 6. Tucked Vorseiiubflager is also designed as a boiler holder for the material to be cut 7 at the same time. They can be moved up and down in the direction of the double arrow 8 stm cut material or stack and can be rested by means of a corresponding pneumatic system. As specified in particular by the? Igo 5 and 4, the feed fingers 6 have an L-shaped shape, one of which is L-shaped! 9 can be moved up and down vertically to the stack in its longitudinal direction, while the other, designed as a contact arm and which can be raised and lowered transversely zvi its longitudinal direction, points in the infeed direction of the material to be cut. 2er AnpreBscheakel 10 is in sight of the double arrow 11 (Fig. 5) in its longitudinal direction displaceable and lockable. It is particularly important when the rear end 12 of the cutting material is not straight and is therefore not in contact with all four thrust bearings. In such grooves is for security
