Definitions

  • the invention relates to a folding apparatus with at least one cylinder provided with folding jaws, which with an cylinder provided with at least one folding knife of an activated cross cutter for cutting.
  • the paper web cooperates in sheet-shaped products and by means of which at least one delivery station can be loaded.
  • the printed image created on a printed paper web is determined by the division of the printing plate or printing plates used. Depending on the printed image a paper web is therefore cut into sheet-like products the length of an entire plate cylinder circumference or a partial circumference, normally half a plate cylinder circumference.
  • the resulting cut, produced with the cross-cutters, is normally designed as a tooth cut, which is often perceived as optically disturbing.
  • the edge containing the tooth cut must therefore often be removed by a smooth cut.
  • the cylinder provided with folding jaws is assigned a plurality of cross cutters, each with a different cutting format, which can alternatively be activated in that the cylinder provided with folding jaws corresponds to one half of the smallest cutting format, by means of tool receiving points Formed circumferential division that the cylinder provided with folding jaws with folding jaws arranged at a distance from the folding blades of the respectively activated cross-cutter and with relative to them by half the folding jaw spacing in the direction of rotation, can be equipped with scissors-type blades protruding over its circumference and that on the ones provided with folding jaws Cylinder is a downstream of the cross cutters in the direction of rotation, which is or is arranged upstream of the knife carrier cylinder, the circumference of which corresponds at least to the largest cutting format and which can be equipped with scissor cutting knives arranged at a distance from the scissor cut knives of the cylinder provided with folding jaws.
  • the knife carrier cylinder can be used to accomplish an orderly transport of the strips separated by the interaction of the scissor cut knives with its scissor cut knife or its scissor cut knives adjacent, preferably rigidly arranged puncture needles provided behind it, which consist of foamed material on which it cooperates with Folders provided cylinder arranged supports can be assigned.
  • the knife carrier cylinder can simply be suctioned off.
  • a further advantageous measure can consist in that the cylinder provided with folding flaps can at least partially be equipped with removable or exchangeable folding or cutting tools.
  • This measure enables the assembly to be adapted to the requirements of the respectively activated cross cutting unit even with a relatively small cylinder circumference.
  • exchangeable cassettes assigned to the removable or interchangeable folding or cutting tools can be provided for this purpose, which can be inserted into corresponding receiving locations on the cylinder side formed by radial grooves. This measure advantageously enables a very quick changeover.
  • the folder shown in the drawings consists of a central cylinder 1, the circumference of which has a uniform division formed by receiving points for the various folding and cutting elements, and around which two cross cutters 2 and 3, a knife carrier cylinder 4 arranged downstream of the cross cutters in the direction of cylinder rotation, and a belt guide 6 leading to a delivery star 5 and a delivery star 7 arranged directly below it are arranged.
  • the cross-cutting units 2 and 3 each consist of a cylinder 9 having a cutter bar 8 and a cylinder 13 attached to it, one or more cutter grooves 10 assigned to the cutter bar 8 and these puncture needles 11 as well as the area between two successive cutting grooves of folding knives 12
  • a pair of draw rollers 14 is assigned to each cross cutting unit 2 or 3.
  • the cross cutting unit 2 activated in FIG. 1 cuts sheet-shaped products with a length corresponding to half a plate cylinder circumference from the paper web 15 drawn off from a paper former (not shown in more detail here). That activated in Figure 2 Cross cutter 3 produces arcuate products with a format length corresponding to an entire plate cylinder circumference.
  • the cylinders 9 provided with knife bars 8 accordingly have varied diameters.
  • the cutter bar 8 is simply removed and the puncture needles 11 and folding cutter 12 are stopped.
  • the respective associated pair of draw rollers 14 can also be passivated by swiveling off a draw roller.
  • the cylinder 13 of the cross cutter 2 which is assigned to the smaller format and is activated in FIG. 1, is provided with three punctures 11 and folding knives 12 on the circumference.
  • the diameter of the cylinder 13 is therefore three times the diameter of the associated cylinder 9 receiving the cutter bar 8, the circumference of which corresponds to half the circumference of the plate cylinder.
  • the cylinder 13 of the cross cutter 3 activated in FIG. 2 and assigned to the larger format has the same diameter as the assigned cylinder 9, which is dimensioned here in accordance with the plate cylinder diameter, and is equipped with a puncture 11 and a folding knife 12 opposite it.
  • the folding blades 12 of the respectively activated cross cutter 2 or 3 work together in a known manner with assigned folding jaws 16 of the cylinder 1.
  • the folding blades 12 and associated folding flaps 16 are arranged so that they pass through the contact area between the cylinder 1 and the respectively activated cylinder 13 together, the sheets held by the punctures 11 at their front end correspondingly releasing the folding blades 12 to form a Cross fold in the respective adjacent flap 16 are pressed in.
  • the punctures 11 which detect the sheets cut from the paper web 15 at their front end also enable a plurality of sheets to be collected one above the other, which are then transferred together to the cylinder 1.
  • the collected products can be stapled together at the point of the later cross fold. In the exemplary embodiment shown, this is only desired in the area of the cross cutting unit 2.
  • a cylinder 17, which has the same diameter and accordingly has three stapling stations, is assigned to the cylinder 13 of the cross cutting unit 2.
  • the cylinder 1 is provided with these scissors-type cutters 18, each of which is arranged in the direction of rotation.
  • the scissor cut knives 18 cooperate with a second scissor cut knife 19 arranged on the knife carrier cylinder 4 to produce a smooth cut parallel to the transverse fold in the region of the rear edge of the products located on the cylinder 1 and held by the folding jaws 16. With this smooth cut parallel to the transverse fold, the edge can be removed with the tooth cut generated in the respectively activated cross cutter 2 or 3 and the punctures generated by the punctures 11.
  • the cylinder 1 has such a circumferential division that when interacting with the cross-cutter 3 associated with the larger format, as can be seen from FIG. 2, at least two and when interacting with Corresponding to the cross-cutting unit 2 assigned to the smaller format, as can be seen from FIG. 1, there are a plurality of folding jaws 16 which are evenly distributed around the circumference, and scissors-type cutters 18 which are arranged downstream of these at half the folding jaw spacing.
  • the cylinder 1 is provided with a 45 0 -division, resulting in eight tool holder bodies whose spacing corresponds to half of the corresponding average format generated on the activated in figure 1 cross-cutting unit 2, the half-plate cylinder screen.
  • the cylinder 11 is accordingly equipped with four folding jaws 16, which are offset by 90 ° relative to one another, and four scissor-cut blades 18, which are each arranged 45 ° behind them.
  • the cross cutter 3 according to FIG. 2 When the cross cutter 3 according to FIG. 2 is activated, two folding jaws 16 offset by 180 ° and scissors-type cutters 18 which are moved back by 90 ° are used.
  • the rest of the existing tool receiving points of the cylinder 1 can be unoccupied or occupied with other tools, as will be explained in more detail below.
  • each folding flap 16 and the respectively assigned scissors-type cutting knife 18, which is arranged in the direction of rotation there is a free tool receiving point, which in the exemplary embodiment shown is equipped with a cassette 21 with a folding knife 22 for producing a second transverse fold.
  • the knife carrier cylinder 4 can also be retrofitted such that a second scissor-cutting knife 19 is available when a scissor-cutting knife 18 passes through.
  • the effective scope of the knife carrier cylinder 4 corresponds to the larger cutting format generated on the cross cutting unit 3 activated in FIG.
  • the knife carrier cylinder 4 as can be seen from FIG. 1, is equipped with two opposing scissor cutting knives 19 which can be expediently removed. In order to convert to the mode of operation according to FIG. 2, a scissor-cut knife 19 is removed.
