Definitions

  • the invention relates to a folding apparatus for the production of folded products which are leveled with a transverse parallel parallel cut with at least one cylinder provided with folding jaws, which is attached to a cylinder with at least one folding knife and which in the area between its folding jaws is each equipped with a scissors-type knife which is equipped with a counter knife cooperates, and with controlled eye movements that intervene in the Falskisppen, which deliver the cross-fold products.
  • the excavation tongues are arranged in a stationary manner outside the respectively assigned flap cylinder in the direction of rotation.
  • the scissor cut knives protrude slightly beyond the circumference of the assigned flap cylinder, the lifting recesses engaging in the flap cylinder must, if they are arranged on this scissor cut knife, which is the case with folders with only one flap cylinder, with each end of a scissor cut knife with their end engaging in the fold flaps the scissors cutting knife passing by should be lifted away to prevent collisions between the excavation bars and the scissors cutting knife passing by.
  • At least one stationary guide table is provided in the area in addition to the circumference of the cylinder receiving the jaws cooperating with the lift flaps, and that the lift tabs are received on the cylinder carrying the assigned jaws and can be activated when passing each guide table .
  • the lifting tongues advantageously have the same speed as the folding products to be lifted out of the assigned folding jaw, so that during the lifting process there are no significant relative movements between the lifting tongues and the folding products, which is very gentle affects the products and the printed image.
  • the excavated products are handed over to a standing guide table, which ensures reliable guidance and at the same time allows sufficient space for unhindered passage of the scissors-cutting knife.
  • These can therefore be arranged on the last jaw cylinder in the working direction, which is inevitably the case where only one jaw cylinder is provided.
  • the measures according to the invention can therefore be used with particular advantage in the case of folding apparatuses for producing once folded products and provided with a smooth cut that is parallel to the transverse fold.
  • the stationary arrangement of the associated guide table ensures a constant distance between the table support and the belts going over it.
  • the tapes of the upper set of tapes that go beyond the guide table can rest snugly on the associated folding jaw cylinder, which ensures that the products are reliably drawn into the tape guide.
  • the stationary control tables also require relatively little space, so that as a result, the accessibility of the associated jaw cylinder is practically not impaired.
  • the guide table or the guide tables with their contact surface can be oriented approximately tangentially to the circumference of the assigned folding jaw cylinder, which practically results in a deflection-free drawing of the products into the belt guide.
  • a further advantageous measure can consist in that the guide table or the guide tables is or are tapered in the manner of a wedge flap cylinder. This ensures that the contact surface of the guide tables can reach up to the area of the cylinder surface and nevertheless sufficient stability is ensured.
  • control table or the control tables can consist of guide tongues arranged next to one another at a distance. These can come into rake-like engagement with the lifting tongues that are received on the folding jaw cylinder and move past them, which ensures trouble-free insertion of the products into the belt guide.

  • a further expedient further development of the superordinate measures can consist in the fact that the lifting bar is pivotally mounted in the lateral cylinder flanges and is connected outside of it with a pivoting lever which is provided with a feeler element which scans a control curve arranged fixed to the frame.
  • control curve can be adjusted about the axis of the assigned jaw cylinder. This measure advantageously enables activation of the excavations at different points, so that alternatively operable displays can be provided.
  • a guide table is expediently provided in the area of each delivery.
  • the folding apparatus shown in FIG. 1 consists of a folding jaw cylinder 1 which is provided with two folding jaws 2 and against which a folding knife cylinder 4 provided with a folding knife 3 is employed, which in turn cooperates with a cutting cylinder 5 to form a cross cutting device.
  • the 'cutting cylinder 5 is provided with a cutter bar 6 which cooperates with a cutting groove 7 provided on the folding measuring cylinder 4.
  • the paper web 8 entering the cross cutter, which is to be guided over a folding former 9 to produce a first longitudinal fold, is divided into arcuate products, the front end of which is received by punctures 10 arranged on the folding knife cylinder 4 and acting in the direction of rotation behind the cutting groove 7.
  • the arcuate products are folded against the folding knife 3 to form a transverse fold Hand over the overlying jaw 2 of the jaw cylinder 1.
  • the once cross-folded products are removed from the folding jaw cylinder 1 and either inserted as so-called tabloid products in a paddle wheel 11 arranged below the folding jaw cylinder 1 or fed via a belt guide 12 to a shear folder 13 for producing a second longitudinal fold.
  • the cross section caused by the interaction of knife bar 6 and cutting groove 7 usually has the shape of a so-called sawtooth cut.
  • the punctures 10 cause permanent punctures in the area of the leading edges of the sheet. It is therefore often desirable to remove the rear product ends after the transverse fold has taken place by means of a clean, smooth cut.
  • the jaw cylinder 1 is equipped in the area between its jaws 2 with scissor cut knives 14 which cooperate with a counter knife 16 arranged on a cutting cylinder 15 arranged on the jaw cylinder 1 and arranged downstream of the jaw cylinder 4 in the direction of rotation of the jaw cylinder.
  • the rear ends of the folding products held with their folding edge in the folding flap 2 which respectively precedes in the direction of rotation are cut off in the form of a smooth cut by the scissors cutting knife 14 and the associated counter knife 16.
  • the separated strips are picked up on the cutting cylinder 15 by, for example, needles arranged downstream of the counter knife 16. then sucked off from this.
  • the cutting cylinder 15 is immersed in a suction channel 17 that can be subjected to a vacuum.
  • a guide table 18 is provided which is fixed to the frame walls and whose table support 19 is oriented approximately tangentially to the circumference of the folding jaw cylinder 1.
  • the jaws 2 of the jaw cylinder 1 are opened automatically.
  • lifting tongues 20 are provided on the folding jaw cylinder 1 in the area of each folding jaw 2, which with their ends engage under the folding products which protrude into the respectively assigned folding jaw 2 and when they pass the relevant control table 18 from the assigned one Lift out jaw 2 and hand it over to control table 18.
  • the guide tables 18 can expediently be formed by a plurality of tongues which are arranged next to one another at a distance and are laterally offset in the axial direction with respect to the guide tongues 20, so that the activated lifting tongues 20, which in the activated state assume approximately the position indicated by broken lines in FIG. 1, hereby can come into arithmetic engagement, which enables a reliable transfer of the products to the respective control table 18.
  • the cylinder-side end of the guide tables 18 is so far apart from the circumference of the adjacent jaw cylinder 1 that the scissors-type cutters 14 projecting slightly over the circumference can pass unhindered.
  • the guide tables 18 are tapered wedge-like on the cylinder side, so that the required distance from the folding jaw cylinder 1 is minimized.
  • the band guide 12 leading to the sword folding mechanism 13 consists of an upper band set 21 and a lower band set 22.
  • the bands of the upper band set 21 lie snugly on the flap cylinder 1 and run with a small distance corresponding to the product thickness, which is the distance between the facing bands corresponds to the upper and lower belt guides 21 and 22, respectively, over the bearing surface 19 of the guide table 18 arranged at the entrance to the belt guide 12.
