Definitions
- the invention relates to a folder on web-fed rotary printing presses according to the preamble of claim 1.
- Known folders of this type are usually referred to as fixed-format flap or puncture folders (magazine: "Der Polygraph", Issue 13, 1954, pp. 742-745, Fig. 5).
- the section lengths separated from the knives of the knife cylinder are taken over by controlled punctures on the collecting cylinder and, after collecting by a folding knife in the collecting cylinder, are folded into a folding flap on the flap cylinder and then z. B. designed via a paddle wheel.
- These known folders are not able to lay out trimmed products because the puncture marks are present on the folded product and must be removed by trimming in a separate operation.
- Another known version of a folder (DE-PS 16 11 283) also shows a fixed-format folder with controlled grippers and a trimming device for the folded products. In this version, an additional pair of cutting cylinders is provided and there is no possibility of collecting the specimens.
- the version of a folder shown in CH-PS 477 979 is a variable gripper folder in which different section lengths can be cut, collected and folded. Folders of this type are considerably more complicated and expensive and are therefore used only on rotogravure printing presses of variable size.
- the object of the invention is to provide a folder in which the by a longitudinal folding device, for. B. a funnel, longitudinally folded paper web cut into individual copies and once are collected and in which the collected specimens are glued together and laid out trimmed.
- Another advantage of the described embodiment according to the invention is that no controlled punctures are provided in the collecting cylinder, so that a largely closed hardened outer surface could be achieved.
- the cylinder can be manufactured practically without imbalance and can therefore work largely free of vibrations. Since no control forces for the puncture control can act on the cylinder body, the vibrations that occur as a result are also avoided, so that an exact cutting of the paper web is ensured.
- the folder shown in FIG. 1 uses a funnel 2 for the longitudinal folding of the paper web 1.
- the folded paper web 1 is fed via the pulling rollers 3, 4 to the collecting cylinder 5, which cooperates with a knife cylinder 6.
- Pressure rollers 7, tongues 8 and a ribbon line 9 are provided on the collecting cylinder 5 to support the paper transport.
- the circumference of the collecting cylinder 5 corresponds to three format lengths, so that accordingly three rows of dots 10, 10 ', 10 "are provided.
- the circumference of the knife cylinder 6 corresponds to two format lengths, so that two cutting devices 11, 12 are provided a double knife 13, while the cutting device 12 is provided with a single knife 14.
- the trimming strips 15 separated from the double knife 13 on both sides of the puncture rows 10 are taken over by a brush strip 16 on a carrier shaft 17 rotating in the opposite direction of rotation to the collecting cylinder 5 and fed to a container 19 by scrapers 18.
- the trimmed and collected specimens 20 are fed to the delivery 24 via the brush rollers 21, 22 and the ribbon line 23.
- the drum 25, which is driven via the intermediate wheels 26 and 27, is used to drive the band line 23.
- the individual specimens 20 are placed in a scale on a delivery belt 28 and are distributed leads. Guide tongues 29 are provided over the delivery belt 28.
- the pulling roller 4 is assigned an adhesive device 30, with which an adhesive strip is applied cyclically to every second section length in the region of the longitudinal fold edge, so that after cutting, the two collectibles are glued together via the adhesive strip.
- FIG. 2 differs from that described above in that a folding knife cylinder 31 and a folding jaw cylinder 32 are arranged downstream of the collecting cylinder 5 and the knife cylinder 6 in the device for the delivery.
- the belt line 33 wrapping around the brush roller 21 and the band line 34 wrapping around the brush roller 22 feed the collected specimens with the assignment of a tongue 35 to the gripper row 36 of the folding knife cylinder.
- the collecting cylinder 5 has a smooth, hardened outer surface, in which slots 42 are provided at a certain distance, in which the circumference is offset by 120
- Puncture strips 40 are arranged.
- further slots 42 are provided in the cylinder jacket, offset by 30, in which the puncture strips can likewise be accommodated. It is thus possible in this embodiment to shift the three rows of punctures 10, 10 ', 10 "each by 30 ° and to turn the cylinder accordingly with respect to the knife cylinder, so that the puncture strips 40 are always in the slots 42 opposite the knives 13 of the knife cylinder 6
- the collecting cylinder 5 can be rotated by 30 in each case, so that a new cylinder jacket surface interacts with the knives 13, 14.
- the slots 42 which are not required can be filled with filler pieces 43
- Both the puncture strips 40 and the filler pieces 43 are fastened to holders 44, which are each screwed onto both end faces of the collecting cylinder 5.
- the puncture strips 40 and filler pieces 43 are fastened to the holders 44 by means of screws 45.
- a separate individual copy is located in front of the cutting device 11 on the lateral surface of the cylinder, which is guided through the row of dots 10 'and covers approximately 120 of the lateral surface.
- a collective copy is applied to the already existing specimen and taken over by the puncture row 10, which after a rotation of about 120 ° is separated by the cutting device 12.
- the two specimens described last are removed as a collected product by the brush rollers 21, 22.
- the collecting cylinder 5 has an odd number of rows of dots installed in the cylinder, these being permanently installed in the exemplary embodiment shown.
- the knife cylinder 6 has an even number of cutting devices for the longitudinally folded paper web.
- a spacer bar 46 is provided between the double knives 13, which is centered on the body of the knife cylinder 6 via the centering 47.
- Clamping rails 48, 49 are provided on both sides of the double knives 13, the outer surface of which is adapted to the knife cylinder 6.
- the two clamping rails 48, 49 can be braced against one another by means of the screws 50, as a result of which the double knives 13 are also held.
- Both the two clamping rails 48, 49 as well as the double knife 13 and the spacer bar 46 form a unit that can be aligned and adjusted outside the knife cylinder 6.
- the height of the double knife 13 can be set very precisely here.
- the unit itself is then attached to the body of the knife cylinder 6 by means of screws 51. It is possible to change the distance between the two double knives 13 by means of spacer strips 46 of different widths.
- FIG. 5 differs from the embodiment of FIG. 4 in that here the individual knife 14 rests on a spacer bar 52 which also receives a centering 53.
- the individual knife 14 can be clamped with the spacer bar 52 and the two clamping rails 54, 55 via the screw 50.
- the setting, adjustment and fastening of this unit is carried out exactly as described in connection with FIG. 4.
