Definitions

  • the invention relates to a variable folding apparatus with a collecting cylinder, to which a folding jaw cylinder is assigned, the circumferential section lying in front of the folding jaw cylinder is wrapped in band guide belts and which, with the holding devices for the leading edges being controlled by it, fed by the band guide belts during each revolution, in a lying state on the Folding jaw cylinder is provided for strand sections to be transferred.
  • the layer of the multilayered material strand fed to the cross cutter is assigned to the cover and consists of thicker material than the other layers, this results not only in a thicker cover sheet, but also in a thicker inner sheet, which is undesirable. For this reason, the complete manufacture of such products in the folder has not yet been possible. Rather, it is necessary to collect the cover sheets and the inner part in a bookbindery, which requires a high outlay on personnel, transport and storage.
  • variable folder of the type mentioned at the beginning, with which the production of complete products with an inner part and an envelope consisting of material different from the inner part is possible in the folder and which is nevertheless simple in construction and one high operational reliability and manufacturing accuracy guaranteed.
  • the collecting cylinder interacts with two circumferential sections lying one behind the other in the direction of rotation in a slip-free manner, and from which the rear circumferential section in the direction of rotation rotates looping tape guide with strand sections to be collected on it in the course of successive revolutions, forming the inner part of a booklet to be produced, and from the band guide looping around the front peripheral section rotating in the direction of rotation, while observing the gaps corresponding to the gathering process, at least with a cover of the strand sections forming the respective booklet to be produced, and that the holding members assigned to the sheet leading edges can be activated with each revolution of the collecting cylinder in the area of the circumferential section wrapped by the band guide assigned to the envelopes and can be passivated in the circumferential area behind the folding jaw cylinder each time the strand sections lying on top of one another are transferred to the folding jaw cylinder.
  • the holding members of the collecting cylinder which can be designed as flat single grippers, which grasp with each revolution of the collecting cylinder, carry out this re-gripping process in an advantageous manner when all strand sections of the complete booklet lie on top of one another, which ensures reliable transfer to the folding jaw cylinder despite the separate feed the cover sheet here possible collective production for collating the inner part ensures that with the help of a printed paper web, which can be processed in an advantageous manner on a printing press, a high total number of pages of the inner part can be achieved.
  • the separately supplied envelopes can be removed from a prefabricated roll, which can not only have a positive effect on the operational process, but at the same time advantageously ensures that the color in the area of the envelope sheets has already reached a high degree of dryness, so that a high acceleration in the The area of the tape guide for producing gaps corresponding to the gathering process in the area of the inner part is harmless.
  • the advantages that can be achieved with the invention can therefore be seen in particular in excellent economy.
  • the belt guide belts of the two belt guides interacting with the collecting cylinder can be laterally offset from one another at least by the belt width. This is a mutual, galvanizing-like engagement of the two belt guides possible, so that there is advantageously only a very small distance between the circumferential sections of the collecting cylinder which are wrapped by the two band guides, which means that high operational reliability and reliability can be expected.
  • the small gusset between the two tape guides can be bridged simply by curved guides, preferably designed as stationary guide tongues.
  • the band guide belts on the mutually facing sides of the two band guides can be guided on the collecting cylinder side via deflection rollers which are arranged next to one another and are preferably arranged on a common axis and which advantageously have different diameters.
  • a further advantageous embodiment of the superordinate measures can consist in that the strand plane of the strand of material passing through one of the upstream of the belt guide in the direction of rotation, preferably arranged above the collecting cylinder, cuts the collecting cylinder like a secant. Compared to the previous arrangements, in which this strand plane tangentially touches the collecting cylinder, this advantageously results in an upward enlargement of the possible collecting cylinder wrap.
  • the holding members of the collecting cylinder are designed as preferably flat single grippers ensures that no collisions wrap around the front circumferential section
  • the gripper that can be activated with the band guide associated with the cover sheet and the band guide bands are to be feared.
  • a stapling device assigned to the collecting cylinder it can advantageously be arranged in the region of the peripheral section wrapped by the band guide assigned to the envelopes. This ensures that stapling only takes place when all the layers of a booklet lie on top of each other. On the other hand, this results in a very compact arrangement in which no significant space requirement is required between the end of the above-mentioned cover-side tape guide and the folding jaw cylinder.
  • a preferably optically acting scanning device that scans the position of the envelopes can be provided in the area of the band guide assigned to the envelopes, by means of which a cross cutter arranged upstream of the band guides assigned to the envelopes and / or the material strand assigned to the envelopes and / or the band guide assigned to the envelopes can be actuated for advancing or resetting, which can be expected to increase the manufacturing accuracy.
  • the belt guide assigned to the envelopes can consist of at least two successive sections, each of which the front section in the transport direction can be driven faster than the respective upstream section.
  • the turn-over of the strand sections takes place in several stages to achieve the required gaps, what a high degree of protection can be expected.
  • the successive sections can expediently each have tape guide belts which are laterally offset from one another by the bandwidth and, with their end regions facing one another, engage in one another in a galvanizing manner.
  • Another advantageous measure can be that the rear upper belt roller of the front, faster section of the multi-part belt guide is adjustable in height. These measures enable fine adjustment of the acceleration in the transition area.
  • a further expedient measure can consist in that a start stop which intervenes periodically in the transport plane is provided in the area of the front, faster belt guide section, the speed of which is preferably slightly reduced compared to the belt speed. This measure enables a highly precise clocking of the cover sheets.
  • the folding apparatus shown in Fig. 1 consists of a collecting cylinder 1, which is provided with adjustable holding members 2 in the form of grippers and with folding knives 3 arranged between these grippers and detecting the leading edges of the strand sections supplied in each case.
  • a folding jaw cylinder 4 is set on the collecting cylinder 1, the folding jaws 5 of which take over the sheet packets transferred from the folding knives 3 to form a transverse fold.
  • the cross-folded products are designed in a manner known per se by means of a band guide which interacts with the folding jaw cylinder 4 and is no longer shown here and a paddle wheel.
  • the collecting cylinder 1 is assigned two belt guides 9 and 10, which loop around two circumferential sections 11 and 12 of the collecting cylinder 1, which are arranged in front of the folding jaw cylinder 4.
  • the band guides 9 and 10 are preceded by cross cutting devices 13 and 14, respectively, which subdivide a respectively supplied strand of material 15 and 16 into arcuate sections, which are accelerated to the peripheral speed of the collecting cylinder 1 via the band guides 9 and 10 and transferred to the latter.
  • the belt guides 9 and 10 are driven so that they work together with the collecting cylinder 1 without slipping. With the belt guide 9 wrapping around the rear circumferential section 1 in the direction of rotation of the collecting cylinder 1, the collecting cylinder 1 is loaded with strand sections of the strand 15 which are to be gathered together to form the inner part 8 of strand 16 to.
  • the envelopes 7 are cut from a pre-made narrow paper web.
  • the strand 15 containing the inner part 8 consists of several layers which are formed by strips into which a wide printed paper web is divided.
  • the paper web giving off the strand 15 is printed in such a way that two or more strand sections of the strand 15 are collected with the aid of the collecting cylinder 1 in a manner known per se, ie can be placed on top of one another.
  • the fold Knife 3 controlled in a manner known per se so that not every sheet package taken over is immediately released again, but remains on the collecting cylinder 1 during two or more revolutions, so that several sheet packages are placed on top of one another.
  • the envelopes 7 are fed in such a way that an envelope sheet is placed only on each inner part package formed by collecting.
  • the speed of the strand 16 and the cross cutting device 14 is therefore correspondingly reduced compared to the speed of the strand 15 and the cross cutting device 13.
  • the sections of the strand 16 forming the envelopes 7 are accelerated to the peripheral speed of the collecting cylinder 1, gaps being created between two successive strand sections.
  • two sections of the strand 15 are to be collected to form an inner part 8.
  • the collecting cylinder 1 is provided with a five division.
  • the folding knives 3 are controlled so that every second folding knife is activated when the folding jaw cylinder 4 is passed.
  • the speed of the strand 16 and the cross cutter 14 is 50% of the speed of the strand 15 and the cross cutter 13 assigned to it.
  • the required gaps between two successive sections of the strand 16 forming an envelope 7 each correspond to a section length.
  • the required acceleration therefore advantageously remains within limits. If a simple collecting process is not sufficient to achieve the desired number of pages of the booklet 6 to be produced, multiple collecting can take place
  • the grippers forming the holding members 2 are designed in the exemplary embodiment shown as flat single grippers. These first capture the first strand section passed through the belt guide 9 to the collecting cylinder 1 and take effect in the subsequent collecting process. The gripping takes place in the area of the front circumferential section 12 which is wrapped in the band guide 10, all layers of the inner part 8 and the sheet forming the envelope 7 lying on top of one another and being detected.
  • the flat single grippers can reach out without risk of damage, i.e. under the sheet packs pressed by the band guide 10 o
  • the grippers are opened as soon as the downstream folding knife 3 is activated and engages with the opposing folding flap 5.
  • a stapler 17 assigned to the folding jaw cylinder 1 is provided, which is provided in order to achieve a high degree of compactness and space-saving arrangement in the area of the front peripheral region 12 wrapped by the band guide 10.
  • the staples are attached in the area between two tape guide tapes.
  • the cross cutter 14 assigned to the cover-side strand 16 is offset in parallel therewith.
  • the plane of the strand 15 passing through the cross cutter 13 intersects the collecting cylinder 1 like a secant.
  • the belt guide 10 which wraps around the front circumferential section 12 is guided from the side to the collecting cylinder 1 and therefore has a 90 ° deflection.
  • the tape guides 9 and 10 each consist of two consecutive sets of tapes of different lengths formed from adjacent tape guide tapes.
  • the longer, outer set of straps wraps around the assigned circumferential section of the collecting cylinder 1.
  • the shorter, inner set of straps ends in the circumferential area upstream of the wrapping.
  • the outer band set 18 of the band guide 9 assigned to the rear circumferential section 11 and the inner band set 19 of the band guide 10 assigned in the front circumferential section 12 engage with one another.
  • the band guide bands of the band guides 9 and 10 are therefore offset from one another by approximately the band width on the collecting cylinder side and are deflected by means of deflecting rollers 20 which are arranged next to one another and which are on a common, extending across the entire machine width axis can be arranged.
  • the diameter of the rollers 20 assigned to the band guide bands of the inner band set 19 of the band guide 10 is slightly smaller than the diameter of the rollers assigned to the band guide bands of the outer band set 18 of the band guide 9, as a result of which collisions of the band set 19 with the collecting cylinder 1 which does not unwind thereon are reliably eliminated are.
  • sheet guides 21 formed by stationary guide tongues are provided here. It would also be conceivable to press the sheet packs in the intermediate area onto the circumference of the collecting cylinder by means of an air stream or the like.
  • the tape guide 10, through which the cover sheets are accelerated to achieve the gaps required in accordance with the collective production between two consecutive sheets, as well as the tape guide 9 for feeding the strand sections emitting the inner part 8 can be formed in one piece. Since the envelopes 7 can be cut from a prefabricated roll, there is no risk of smearing even at high accelerations in the area of the belt guide 10.
  • the belt guide 10 consists of two successive sections 10a, 10b, the speed of which is graduated so that the front section 10b in the transport cylinder direction runs faster than the rear section 10a on the cross cutter side.
  • the sections 10a and 10b of the band guide 10 can simply be arranged one behind the other at a small distance, where the distance is bridged by stationary guide tongues or the like.
  • the tape guide sections 10a and 10b arranged one behind the other engage with one another in a galvanizing manner with their mutually facing end regions, which allows a direct transfer of the transported strand sections while maintaining their positive guidance and thus their alignment their width offset against each other.
  • the length of the galvanizing-like engagement ie the overlap area of the band guide sections 10a and 10b arranged one behind the other, can be changed in accordance with the product length.
  • the transport planes of the belt guide sections arranged one behind the other run in the overlapping area, which results in a smooth transition.
  • the rear belt roller 22 associated with the inner belt set 19 can be adjusted in height. This results in a particularly gentle handling of the strand sections to be transported while maintaining their positive guidance in the transition area between the sections 10a and 10b.
  • a stop 23 which intervenes periodically in the transport plane of the tape guide and which runs at a somewhat reduced speed compared to the tape speed and on which the leading edges the strand sections transported by the belt guide 10 run up and thereby experience an exact alignment and exact timing.
  • a rotating shaft 24 is provided in the exemplary embodiment shown, on which disc-shaped plates 25 which are set against the associated band guide bands are placed, which reach radially between each two bands and have the stop 23 forming radially projecting fingers.
  • the shaft 24 can advantageously be driven continuously.
  • the position of the strand sections each forming an envelope 7 is scanned by an optical scanning device 26 in the region of the front section 10b of the band guide 10 which wraps around the circumferential section 12 which is in the direction of rotation of the collecting cylinder 1, as a result of which an exact superimposition of the sheet package emitting an inner part 8 and the associated one Envelope is ensured.
  • the cross cutter 14 is moved forward or backward via the scanning device 26. Accordingly, the strand 16 must also be moved forward or backward, which can be done by appropriately controlling the strand feed members 27.
  • the tape guide 10 could simply be the front tape guide section 10a forward or back accordingly.
