Definitions
- the invention relates to a folded product and a method for its production and a device for carrying out the method according to the preamble of claims 1, 3 and 4.
- the disadvantage here is / that the folded products after a successful cross folding bulge near the Querfalzkante, which may result in further processing and further transport to difficulties.
- the invention has for its object to provide a folded product and a method and an associated device with which an arching of the folded product in the vicinity of the transverse fold largely avoided.
- FIG. 1 is a side view of two opposing jaw elements in connection with a folding knife and a signature, in an enlarged view
- FIG. 2 is a view A of FIG. 1 showing a first profile of the jaw elements according to the invention
- FIG. 3 is a perspective view of a jaw element with the first profile according to the invention
- FIG. 4 is a view A of FIG. 1 showing a second profile of the jaw elements according to the invention
- Fig. 5 shows a cross section VV through the profi liert
- FIG. 6 is a perspective view of a first jaw element with a second profile according to the invention.
- FIG. 7 is a perspective view of a second jaw element with a second profile according to the invention.
- Fig. 8 is a perspective view of a folded product produced according to the invention in a reduced view.
- a folding jaw cylinder 1 has, in a known manner, a plurality of folding jaw systems distributed over its circumference.
- Each jaw system consists of a first row of jaw elements 4 lined up on a support and pivotable in a known manner, which interact with a second row of cylinder-fixed Gegenfa Izk lappene elements 3. Both rows of folding jaw elements 3, 4 can also be arranged pivotably.
- each folding jaw element 4 or each counterfeit Izk lappene element 3 consists of a fastening plate 5, 10 and a folding tool carrier 15, 10.
- the mounting plate 10, 5 each
- Each folding tool carrier 15, 20 has a beveled folding surface 11, 12 or 13, 14. At least one fold surface 11 or 12 or 13 or 14 is profiled therefrom. If two fold surfaces 11, 12 and 13, 14 are profiled, then both fold surfaces 11, 12 and 13, 14 can be brought together in a comb-like manner when the fold jaw is closed.
- both fold surfaces 11, 12 carry z. B. high-lying parts 16, 18 with a rectangular cross-section (Fig. 2), extending from an outer retaining edge 21, 22 over the folding surface 11, 12 with a length l, z. B. 4 mm towards an inner folded edges 23, 24.
- the high lying parts 16, 18 each have a width e and are each separated or adjacent by low lying parts 17, 19 with a width d.
- the high lying parts 16 of the Gegenfa Izk lappene element 3 are in meshing engagement with the closed jaw 8 with the ni edri gli lying parts 19 of the jaw element 4.
- ni edri gli egenden parts 17 of Jacobfa Izk flap element 3 with the high parts 18 of the Fa Izk lappene element 4 meshing so that a signature 7 after transverse folding by means of a folding knife 6 to a folded product 9 also receives short longitudinal embossments 26 (FIG. 8).
- the longitudinal embossments 26 do not run parallel to the fold edge 23, 24, the so-called transverse fold edge.
- the high-lying parts 16, 18 and the low-lying parts 17, 19 run from the outer holding edge 21, 22 at an angle alpha ⁇ 180 °, z. B. from 10 ° to 170 ", but preferably at an angle alpha of 90 °, to the fold edge 23, 24 of the fold surface 11, 12 (FIGS. 1 to 3).
- the fold product receives 9 embossments 26, which are preferably in transport direction G of the folded product 9 or in the direction of movement F of the folding knife 6.
- the embossments 26 are rectangular in cross-section, so that the section modulus 26 of the folded product 26 is increased in its transport direction G.
- the low ed lying parts 17, 19 have the same level difference compared to the lying parts 16, 18 over the entire length l of the folding surface 11, 12.
- the high lying 16, 18 with respect to the low 11 parts 17, 18 from the outer retaining edge 21, 22 to the inner folded edge 23, 24 of the folded surface 11, 12 each extend at an angle Beta, z. B. of 4 ° (Fig. 1 and 3).
- the high lying parts 16, 18 are from the outside Retaining edge 21, 22 towards the inner fold edge 23, 24 of the fold surface 11, 12 is increasingly wedge-shaped, ie the surface of the fold surface 11, 12 increases continuously in the direction mentioned.
- each pivotable Falzklappenelement 4 carries on its rebate surface 14 protruding parts 27 each having a triangular uer4.000 Q.
- Each cylinder-fixed Gegenfa Izk lappene element 3 has on its fold surface 13 grooves 28 which can be brought into positive engagement with one another when the fold jaw 8 is closed, ie the distance between the fold surfaces 13, 14 is zero.
- the grooves 28 can be continuous, i. H. be formed with a width h over the entire length l. The same then applies to the protruding parts 27, which are positively engaged with the grooves 28 when the jaw 8 is closed.
- protruding parts 27 or grooves 28 run from the outer retaining edge 21, 22 at an angle alpha ⁇ 180 °, z. B. from 10 ° to 170 °, but preferably at an angle alpha of 90 ° to the inner fold edge 23, 24 of the fold surface 13, 14th
- the protruding parts 27 and the grooves 28 on the outer retaining edge 21, 22 still have a distance h, z. B. of 12 mm from each other while they end up the fold surface 13, 14, on the fold edge 23, 24, touch each other.
- the surface of the fold surface 13, 14 increases continuously in the direction mentioned.
- a pitch angle beta e.g. B. of 4 ° exists between a protruding part 27 and the bottom of the groove 28 (not shown).
- the method according to the invention consists in that one in the folding jaw 8
- Fold k l appensys t ems is folded across by the signature 7 introduced signature 7 and thereby receives wave-like embossments 26. Due to the embossments 26, the paper fiber bundle is at least partially stretched. It becomes a permanent deformation, i. H. achieved an embossing.
- the embossments 26 each extend in a length l, preferably in the direction of movement F of the folding knife 6.
- a folded product 9 designed in this way in the immediate vicinity of the outer folding edge 2 has an increased section modulus in the transport direction G of the folded product 9.
- embossing thus gives all the sheets of the folded product 9 lying on top of one another a permanent deformation without the individual sheets being connected to one another in any way, as would be the case with adhesive ripping.
