Feed table of sheet feeders known by a drive roller, which has its own single drive. This known device allows the optional operation as a drawing and sliding mark, by the fact that the trained as a micro electric motor single drive the drive roller with this in constant drive connection and that also the pendulum suspended and locked by a set screw side mark of a on the motor shaft of the Micro motor mounted eccentric can v / ground, with the smallest motor, side mark and drive roller attached to a pivot arm and are pivotable about a horizontal axis. This known device also has significant disadvantages. It is not synchronized with the Llaschinenlauf. A repetitive turn-on and turn-off of the motor (at high speeds up to three times per second) does not guarantee the trouble-free exact operation required by a pull-to-go brand. In addition, mechanical control elements, as they are necessary on Ziehmarkenanschlag oran the front line, at most their function in Kartonaber not meet with paper processing. Another disadvantage is that shocks occur at each switch-on and shocks by the one-sided labile storage of Vorrich- 'tion, whereby no perfect passersign alignment of the sheet can be guaranteed.

A substantially improved compared to the preceding devices Seitenbogen.Bogenausrichtvorrichtung is known from DE-Auslegeschrift 19 50 305. In this, the sheet to be aligned is selectively pushed by a driver roller against an adjustable lateral stop or by a sliding mark against an opposite stop. The control movement required transversely to the direction of sheet travel is achieved by means of a cam-like curve.

It is also appropriate that the interacting with the swab rollers sliding plates are interchangeable with sliding marks and stop ».

It has also proved to be advantageous if a side mark with the swab roll can be operated in the drawing mode while the other side mark is not in action. Another feature of the invention is the fact that bei.weggeschwenkten swab rollers on a.Seitenmarke a stop and on the other side mark a sliding mark is used-is. '

According to the invention is also that the one side mark with the swab role in the drawing operation and the other side mark with the swab role in sliding operation by different settings of the cam portions of the associated curves are operable.

Moreover, it is possible that the one side mark with the swab roll in the drawing mode and the other side mark using the slide mark in the combined drawing and pushing operation are operable.

A significant advantage of the invention is that can be printed by the simple changeover of the device from drawing to sliding operation with a high degree of security and accuracy both thin paper existing sheet and so-called cardboard types while avoiding high changeover times by swung the swab role and instead of the die plate cooperating with the swab roll, a slide plate having a sliding edge can be used.

Pig «1 is shown on the right side of a feed table, a right side mark 1. An arc to be aligned is transported approximately perpendicularly to the plane of the drawing on the line 0 illustrated in FIG. 1, against a front mark. In this case, the right edge of the sheet enters a slot formed between a shell 2 and a sliding plate 8. A swab roller 3 rotatably mounted on a swab roller lever 4 is pivotable about an axis 17 and can be placed on the slide plate 8 through an opening in the clam 2.

The distance of the shell 2 to the sliding plate 8 is adjustable by means of a thumbscrew 7 to adapt to the respective sheet thicknesses to be processed.

The contact pressure of the swab roller 3 can be adjusted by turning a threaded sleeve 19. In order to keep this setting fixed, a knurled nut 20, which is rotatably mounted on the threaded sleeve 19, is counter-folded. In the latter, a spring rod 18 is guided, on which a compression spring 6 is arranged. By this arrangement can thus be changed by the swab roller 3 exerted on the sheet to be aligned pulling or sliding effect, so that an adaptation to the sheet thickness ^ and the surface roughness is possible.

On the right side of a synchronized with the Bogenbransportvorrichtung spindle 25, a curve 15 is fixed, so that it rotates with the spindle 25. On the curved path of the curve 15 runs a roller 14, which causes a pivoting movement of the swab roller lever 4 about the axis 17 via a 'guide lever 16 during a rotation of the spindle 25. As a result, in the same rhythm, the swab roller 3 'briefly against a located between the shell 2 and the slide plate 8 bow, pressed. The swab roll

3 is mounted in the swab roller lever 4 on a head bolt 21 with ball bearings.

The spindle 25 also carries a curve 22. The curve 22 and the curve 15 are fixedly connected to the spindle 25 via a guide bushing 5. The curve 22 is fastened by means of screws 27 to the slotted guide bushing 5. As a result, the curve 22 can be rotated on the guide bush 5 in a simple manner by loosening the screws 27.

The curve 22 is provided at its periphery with depressions whose lateral course represents a control range for the drawing operation and a control range for the shift operation. By adjusting, d. H. Turning the curve 22 on the guide bushing 5 »can thus a temporal · control of the lateral movement of the slide plate 8, d. H. in the forward and backward direction transverse to the transport direction of the sheet, are effected.

In the curve 22 is a role. 11, which is connected to a slider 29. The rotation of the curve 22 thus causes a left-right shift of the guided on guide rollers 12 and 24 slide 29. On the slider 29, the sliding plate 8 is fixed by means of a fastening screw 9.

Due to the arrangement of the curve 15 and the curve 22 on a common synchronized with the sheet transport spindle 25 is now by the shape of the curve areas a vote of the time at which the swab roller 3 sets on the sliding plate 8 ^ with the forward and / or or backward movement of the sliding plate 8 in an advantageous manner possible. If now the right side mark 1 is to work in the drawing mode, the curve 22 on the guide bushing 5 must be rotated so that the curve area, for example

the range of 0 to 180 °, a displacement of the slider 29 and the slide plate 8 in the reverse direction, d. H. to the right, -ausführt when the swab roller 3 is lowered by the 'curve' form on the curve 15. As a result, the arc located with its right edge between the swab roller 3 and the sliding plate 8 is pulled against a right stop 28.

If the right side mark 1 is to work in the push mode, the curve 22 must be shifted on the guide bush 5 so that a curve area, for example between 180 and 360 °, a movement of the roller 11 and thus> the slider 29 and the slide plate 8 in Forward direction, d. H. to the left, executes at the time at which the swab roller 3 controlled by the curve 15 touches the slide plate 8. Characterized a lying with his right, edge between the swab roller 3 and the slide plate 8 bow is pushed to the right against a located on the opposite side of the feed table stop.

By using different, but synchronously trained control cam areas, preferably on a curve 22, thus can be adjusted only by turning the curve 22 on the spindle 25 and on the guide bush 5, the side mark 1 of drawing operation on shift operation and vice versa. A shift of the separated by a spacer sleeve 13 from the curve 22 curve is not required. As shown in detail in FIGS. 5 and 6, the adjustment of the cam 22 can be facilitated by the use of alignment marks 26.

Advantageously, the side mark shown in Fig. 1 can be used both on the right and on the left side of a feed table. In Fig. 2 is a

1. 10. 1980 57 635 27

Side mark 30 shown, which is arranged on the left side of the feed table. Since the structure of the side mark 30 of FIG. 2 is substantially identical to the structure of the side mark 1 in Fig. 1, the same reference numerals have been used for each corresponding parts. Since the side marks 1 and 30 used on both sides of the feed table are respectively controlled by curves 15 and 22 which are located on a common spindle 25, an automatic synchronization of the two side marks results, whereby different operating possibilities are adjustable.

5 shows on the left the curve 22 belonging to the side mark 30 (FIG. 2) and on the right the curve 22 belonging to the side mark 1 (FIG. 1). The positions 45; 47 of the two curves 22 apply to the drawing operation. As shown in Fig. 2, the swab roller 3 can be pivoted about the axis 17, so that the side mark 1 in Fig. 1 operates separately in the drawing operation at a setting of the curves 22 of FIG. In the same way, the swab roller 3 can be placed in Fig. 2 and the swab roller 3 are pivoted in Fig. 1, so that the side mark 30 operates separately in the drawing operation.

Fig. 6 shows the adjustment of the curves 22 to the "bushings 5 for the pushing operation." With this setting, for example, the side mark 1 shown in Fig. 1 can operate in the sliding mode, the swab roller being brought out of action in Fig. 2 by pivoting. In the same way, the side mark 30 in Fig. 2 can operate by means of the swaging roller 3, sliding operation · the swab roller 3 of the side mark 1 is swung up in Fig. 1. The arrows 3S to 44 and 49 show the position of the setting marks in the various Curve settings 45 to 48.

A further advantageous operating possibility results from the use of the shift mark shown in FIGS. 3 and 4. In Fig. 3 a sliding mark is shown, which consists of a sliding plate 37 and a cover plate 36. The sheet is pushed in an advantageous manner by a arranged on a sliding edge leaf spring 35. The sliding plate 37 can be placed on the slider 29 on one of the two side markers 1 or 30 with each swivel roller 3 swung away or removed instead of the sliding plate 8 with the screw 9. For this purpose, reference is made to US Pat 3, the stop 32 shown in Fig. 4 can be used on the opposite side when using the sliding mark 37. This stop 32, which is provided with the cover plate 31, is mounted on the slide plate 10 of a side mark Screws 33 are firmly connected in Fig. 2 in Fig. 2, the sliding mark shown in Fig. 3 is mounted with swung-swab 3.

V / eitere operating possibilities are obtained using the sliding mark shown in FIGS. 3 and 4 in combination with a swab roll 3 Thus, for example, the swab roll 3 on the one hand in the drawing operation, while on the other side either the swab 3 in the Sliding operation operates, or the swab roller 3 is reset, and in its place the sliding mark (Fig. 3) is mounted. In such an operation, the curve 22 on the side mark 30 (Figure 2) is according to the cam position, * 45 (Figure 5) and the curve 22 on the side mark 1 (Figure 1) according to the cam position 48 in Figure 9. · Set 6. In a mirror-image operation, the curve 22 of the side mark 30 (Figure 2) is to be adjusted according to the cam position 47 (Figure 5) and the curve 22 of the side mark 1 (Figure 1) according to the cam position 46 (Figure 6).
