According to the invention, this object is trimmed in order to solve the parallel running edges 3 that a rotatable longitudinal rail is provided on the sides of the conveyor device and 4 along the lines A 'and Y as cutting lines, which can be produced in FIG. For this purpose, the large direction of the width and in an essentially plate 1 via conveyors 5 and 6, eg vertical arrangement to transverse seams 5 len, is movable from the direction of the arrow set in broken lines in a large plate, the cutting set arrow Moved forward from Fig. 1 and introduced in directions each with a motor for 'moving a device according to the invention, are equipped in along its longitudinal rail, one with which large panels can be trimmed. In this detector provided with a differential transducer for the case, the center line of the large plate 1 introduced in this way to determine the degree of rotation of the longitudinal rails does not necessarily match, and a deviation detector with several differentials overlaps the center line of the conveyor at a stop line to stop a. Consequently, the arrangement of the large plate of the large plate being conveyed and the detection of the load provided by a deviation detector to be explained later on the deviation of the stopped plate are reproduced in such a way that longitudinal rails are there. 15 measure of the detected deviation can be rotated.

Between these rollers, the edges of the cross rail 8 are also from above and held down and from both sides. At the table 11: st one attached to the lower end of the longitudinal rail 15 Support 74 held, in which a groove 75 with a right-angled cross-section according to FIG. 6 trained is. A roller 76 attached to the surface of the table 11 is disposed in the groove 75, whereby the table 11 in the direction of the arrow in FIG. 7 is moved when the longitudinal rail 15 turns. Bearings denoted by the reference numeral 77 serve to reduce the friction between the supports 74 and the table 11 during the rotary movement of the longitudinal rail 15.

After the construction has been described, the cutting process is then carried out by means of the Device explained.

When the large plate 1, which is arranged on the conveyor between the longitudinal rails 15 and 35 (e.g. a disc roller conveyor) is moved into the cutting device is inserted a further movement of the large plate 1 by a precautionary arranged on the stop line 7 Stop (not shown) interrupted. Simultaneously with the stop of the plate, the deviation becomes the position of large plate 1 (the deviation of the center line of the stopped large plate from the center line of the conveyor) by means of the differential converters 23 and 24 of the large plate 1 contacting deviation detector 22 and the differential converters 27 and 28 of the rail rotation detecting detectors 25 and 26 determined. As a result, the longitudinal rails 15 and 35 in the Weie adjusted so that they are arranged perpendicular to the seams 19, 20 and 21 in the large plate 1.

Then the cutting devices 14 and 34 move along the longitudinal rails 15 and 35, respectively, so that the torches of these cutters with

ίο mechanical accuracy and high efficiency remove the desired amount of material from the side edges of the large plate 1 so that parallel running edges arise. In this case, however, it is not necessary that the cutting devices 14 and 34 are operated synchronously.

From the above it can be seen that the device according to the invention for trimming large panels is designed in such a way that the deviation from the center line of the conveyor

the amount of material from both ends of the large plate can be removed by the cutting devices to produce parallel edges. It there is the advantage that large plates of improved quality by greatly improved parallel running Edges are generated. Furthermore, the efficiency is increased by the automatic processing.
