Definitions

  • the invention relates to a device for the mechanical production of an oblique fold at the beginning of a continuous paper web in a machine for the mechanical folding of sheets such as drawing pauses or the like.
  • Drawing breaks of sizes DIN A 3, A 2, A 1, A 0, 2 A 0 as well as intermediate game sizes are folded according to certain rules (DIN 824) in such a way that they are filed as a package like sheets of size A4 and bound in Condition can also be unfolded. So that the drawing parts folded over the transverse folds are not caught by the stapling mechanism, these parts are folded out of the area of the stapling holes by a diagonal fold as a cover.
  • the longitudinal folds are produced in a continuous process, in which the sheet is inserted into the machine (working at high speed) from stationary feed rollers and the sheet start or part If the folded sheet package is moved back and forth in particular by reversible, that is to say reversible in the rotary movement, but stationary folding rollers, the oblique fold cannot be produced by a triangular table that can be moved up and down, as in the known machine, because this requires the sheet to stand still would. Since it is not possible to start folding at the rear end of the oblique fold (as seen in the direction of travel) when the sheet is running through, the difficulty arises of having to start at the front acute-angled end of the oblique fold.
  • the invention is based on the object of proposing a device for a machine for the mechanical folding of sheets which enables the safe mechanical production of oblique folds even in machines using the continuous process.
  • a fold fold bar arranged spirally on the circumference of a roller and a counter-roller made of resilient material for pre-embossing the diagonal fold of the envelope and a downstream arrangement for folding over the envelope and sharp bending of the pre-embossed diagonal fold.
  • the angle of the oblique fold relative to the sheet edge of the paper web is the same for all formats. This makes it possible for the angle of inclination of the spiral fold fold bar to be the same for all sheet sizes with respect to the axial direction of the roller.
  • the device according to the invention shown in FIGS. 1 to 4 initially contains a pair of inlet rollers 2 with which a paper web 1 (for example a drawing pause) is transported into the device in the direction of the arrow (FIG. 1).
  • a roller 9 arranged at a short distance from the pair of rollers 2 is replaced by an on touring clutch 19 set in rotation.
  • the roller 9 carries on its circumference a spirally arranged fold break bar 5, with which the paper web 1 is pressed into the counter roller 4 arranged below it, which is provided with a resilient covering (for example a rubber covering) (FIG. 2), so that an oblique fold 8 is formed by stamping results in paper web 1.
  • the roller 9 When one revolution has been completed, the roller 9 is stopped and is in the waiting position (FIG. 3).
  • the strip 5 and the counter roller 4 are designed and arranged such that the envelope 6 divided by the diagonal fold 8 is positioned at an angle (upwards) with the impression of the oblique fold 8.
  • the paper web 1 is transported further to the right (as seen in the drawing) and the envelope 6 formed by the oblique fold 8 and still open reaches the area of a brush roller 10.
  • the brush roller 10 is not driven and therefore acts as an inhibitor for the envelope 6 employed , which therefore turns over in its initial region 6a, the brush roller rotating (counterclockwise in FIGS. 1 to 3).
  • the further envelope area 6b reaches the working area of an inclined hold-down rod 12, which also folds the envelope 6 already folded over in the initial area 6a in the remaining area 6b.
  • the rod 12 is also freely rotatable, but is practically still during operation.
  • the front edge of the sheet 11 of the paper web 1 reaches the working area of a pair of rollers 18 connected downstream for sharp bending of the Oblique fold 8. This creates the desired envelope 6 with the oblique fold 8; the pair of rollers 18 also ensures the further transport of the paper web 1.
  • FIG. 5 shows a section of a sheet 30 of size DIN A1 to be folded, in which stitching holes 16 are provided in the lower region on the left sheet edge 11 (binding edge).
  • the transverse folding takes place around the transverse fold 13, so that without the oblique fold 8 the area of the envelope 6 would come to lie in the area of the stitching holes 16.
  • the envelope 6 is formed around the oblique fold 8, which is indicated by the dashed line 15. If the upper part of the sheet 10 is now folded down about the transverse fold 13, the boundaries along the oblique fold 8 are released from the stitching holes 16 in accordance with the dashed line 17.
  • the angle 7 must be at least 6 ° (with DIN 2 A 0 according to DIN 824: 6.72 °).
  • FIG. 6 shows a section of a sheet 40 of size DIN A 0 to be folded, in which two areas have to be folded over in the vertical direction in the transverse folding.
  • the oblique fold 8 has the same angle 7 as in FIG. 5.
  • a folding sheet or another rigid locking member projecting into the path of the folded envelope 6 can also be provided.
  • one roller of the pair of rollers 18 can be designed as a segment roller.
