Definitions

• the present invention relates to a method for producing a folded sheet, wherein the sheet is fed, aligned and folded.
• a device for producing a folded sheet in particular for carrying out the method, with a feed, an aligning device and at least one folding device specified.
• the known device basically comprises a feeder, an alignment device and a folding machine and already allows a fold obliquely to an edge of a rectangular arc.
• a multiply folded product requires in the known method a plurality of process steps, in particular two alignment steps and at least two different folding devices and is therefore costly.
• Another disadvantage is that the skew is necessarily tied to the Messerfalzautomaten and thus initially leaves no choice with regard to the folding device.
• the invention has for its object to provide a method and apparatus of the type in question, which simplifies the production, made more flexible and reduces costs. According to an alternative device, a reduction of manufacturing costs by quality improvement should be achieved.
• the above object is achieved with respect to the method by the features of claim 1.
• a method of the type in question is designed such that during the feeding the sheet is brought into an inclined position to the running direction, that the skewed sheet is aligned and that the aligned sheet is transferred to a folding device to at least one fold generate, which extends angled to the edges of the sheet.
• a device of the type in question according to the first alternative is designed such that the folding device is a pocket folder, whose first pocket is tuned in the shaping on brought into oblique edges of the sheet.
• a device of the type in question according to the second alternative is configured such that the alignment device has stops which are rotatable about a rotation axis in the direction of the aligned sheet.
• a pocket folder is provided whose first pocket is matched to the inclined edges of the sheet.
• a first pocket is provided, which the oblique edges of the aligned
• the production costs can be minimized by improving the quality if the separate alignment device according to the invention has special stops.
• the peculiarity of these attacks is directed to their novel mobility. Stops according to the prior art known from practice, are moved vertically down to the support surface of the sheet down to release the path for the sheet to a next processing station. This can lead to damage of the sheet edges.
• the device according to the invention according to the second alternative now provides stops that are rotatable about an axis of rotation in the direction of the aligned sheet. The stops are swung away without being in contact with the sheet edges. As a result, damage is advantageously excluded and costs reduced by avoiding waste products.
• the alignment device could advantageously be present as a separate structural unit, which can be combined with different feeders and / or folding devices.
• the movement of the conveyor belts could be exploited to continue to drive the sheet when entering the alignment.
• the sheet could partially remain on the conveyor belts when entering the alignment device and be acted upon by these with feed force.
• a vacuum could be applied to the sheet to maintain the desired position so that it is fixed in the alignment created by the stops.
• an intake belt or a suction roll could be provided.
• the stops are to be removed from the transport path, so that in this way the way to release to the folding device will release.
• the transport to the folding device could take place via the suction belt or the suction roller.
• the suction belt could already be in motion when the sheet comes from the feeder.
• only very low speeds of at most 1 m / min come into consideration so as not to obstruct the intake process.
• the sheet could be folded at least once, angled to the edges.
• a plow folder is selected according to a variant of the method, then either a pre-grooved sheet is to be used or the sheet must pass through a groove work before entering the plow folder.
• the plow folder can be equipped with two parallel shaped sheets and form two folds with one pass and fold the sheet accordingly.
• a pocket folder is selected as folding unit, it is possible to carry out several folding operations in different pockets of the pocket folder.
• the first pocket of the pocket folder must be shaped to match the skewed edges of the sheet. Quasi an "over-corner" recording must be provided within the bag.
• the corner opposite the first fold can also be folded without special internal shaping of the second pocket by driving over the first fold into the second pocket without further ado, but increasing the run-in length to form the second fold parallel to the first fold. If it is then desired to fold or fold the two remaining 90 ° corners in this quadrangular arc, then the double folded sheet in this example can leave the pocket folder and be transferred to a second pocket folder whose first pocket is a The second pocket folder could be positioned at 90 ° to the first pocket folder so that the sheet no longer needs to be turned, it being understood that the folds are removed from the fold.
• the aligning device downstream Taschenfalzwerk and / or another Taschenfalzwerk could have up to twelve pockets.
• a plurality of folds can be formed directly within a folding device, and complex shapes can arise that may be of particular interest for advertising broadcasts.
• the alignment device could have stops which are tuned to the skewed edges of the sheet.
• the stops could be rotatable about axes of rotation in the running direction of the aligned sheet.
• the stops are unceremoniously swung away without being in contact with the sheet edges.
• the axis of rotation of the stops extends transversely to the direction of the aligned sheet. If the stop is fixed below the support plane of the bow, it is pivoted downwards. If the stop is fixed above the support plane of the sheet, it is rotated to release the path to the folding device upwards.
• a control could be provided which coordinates the movement of the stops at the right time.

• Fig. 1 the steps of the method and the device according to the invention are schematically sketched. It is about the production of a four-fold folded sheet 1 in this embodiment, which is first fed, aligned and finally lent be folded.
• the sheet 1 is brought during feeding by means of conveyor belts 7, 8 in an inclined position to the direction A, wherein the sheet is rotated in the direction of rotation B exactly 90 °, so that a corner of the quadrangular here arch 1 in the direction of Aligning device 2 has.
• the conveyor belts 7, 8 shown in FIG. 2 have different speeds in order to realize the rotation in the direction of rotation B. Specifically, the conveyor belt 7 runs faster than the conveyor belt 8.
• the slanted sheet 1 is now aligned in the aligning device 2 and then transferred to a folding device 3, to produce a fold 4 always shown in phantom or a fold along this fold 4, which extends at an angle to the edges 5, 6 of the sheet 1.
• the alignment device 2 is a separate structural unit that can be combined with different feeders and / or folding devices 3.
• the sheet 1 partially remains on the conveyor belts 7, 8 when it enters the alignment device 2 and is acted on by these with feed force.
• the sheet 1 reaches up to the three stops 9 of the alignment device 2, at which the edges 5, 6 of the sheet 1 are aligned.
• a vacuum is applied to the sheet 1, so that this in the 9 through the attacks generated alignment is fixed.
• the vacuum is applied via four suction belts 10 which transfer the sheet 1 to the folding device 3 after the path has been cleared by the temporarily removable stops 9.
• the sheet 1 is first folded once according to fold 4 angled to the edges 5, 6 folded.
