Definitions

  • the invention relates to a superstructure according to the preamble of claim 1.
  • DE 24 35 583 C2 and DE 24 35 972 C2 also show a folder superstructure that can be switched over to two operating modes.
  • inlet rollers arranged in two rows are provided.
  • this known arrangement also has a comparatively large overall height.
  • the web feed is different and difficult for the different types of production.
  • the measures according to the invention enable a very low overall height, in particular above the folder inlet.
  • the second turning bars to be arranged above the folder inlet and the deflecting rollers which can alternatively be approached can therefore advantageously be at a height which does not exceed the height of the turning bar register containing the first turning bars.
  • the folding apparatus 1 on which FIG. 1 is based is arranged transversely to the longitudinal direction of the upstream printing press, which is only indicated by its side walls 2, 3, i.e. the direction of delivery of the folder 1 is transverse to the transport direction of the paper web in the area of the printing press.
  • the folder 1 has an inlet 5 provided with pull rollers 4, to which a strand package 6 is fed.
  • the drawing rollers 4, like the other rollers and cylinders of the folding apparatus 1, run in the transport direction of the printing press, that is to say at right angles to the cylinders and rolls of the printing press.
  • the strand package 6 consists of a plurality of strands 6b, lying one on top of the other, into which the paper web 6a printed in the printing press is separated by longitudinal cuts. Magazine production is simply wide, loosely stacked poles. Funnel production is a double-width strand with a funnel longitudinal fold.
  • the folder 1 is inserted under a superstructure 7, which is provided with guide members for the individual strands.
  • the folder 1 is arranged so that its inlet 5 is laterally offset from the central longitudinal plane of the printing press.
  • the superstructure 7 has, in the region of the outlet of the paper web from the printing press, the first and the highest turning bars laterally offset from one another 8, which deflect the strands passed over them by 90 and have a mutually covering strand guide Act.
  • nine first turning bars 8 are provided, ie the paper web can be separated into nine strands.
  • the first turning bars 8 are, as can best be seen from FIG. 2, designed as overhung rapid turning bars which are adjustable transversely to the running direction of the incoming paper web.
  • the first turning bars 8 are assigned cross members 9 attached to the side walls 2, 3 of the printing press or corresponding extensions of these side walls, on each of which a ship 10 provided with a first turning bar is slidably received.
  • five second turning bars 11 are also provided, which are laterally offset from the top five first turning bars 8, that is to say transversely to the running direction of the paper web running out of the printing press.
  • the extent of this lateral offset is chosen so that the second turning bars 11 are outside the turning path of the first turning bars 8, ie at least laterally outside the working area of the printing press.
  • the offset is chosen so that the second turning bars 11 are already laterally outside the plane of the adjacent side wall 3.
  • the second turning bars 11 can, as can also be seen in FIG. 2, be designed as overhung rapid turning bars.
  • the second turning bars 11 are not laterally adjustable, but are fixed against each other.
  • a fixed, ie stationary, arrangement above the folder inlet 5 is provided.
  • An end wall 12 running transversely to the machine side walls 2, 3 is provided for receiving the second turning bars 11, which are arranged here in a fixed manner. This can simply be attached at right angles in the region of the rear end of the side walls 2, 3 to one of these side walls, here to the side wall 3.
  • a driven pull roller 13 and a subordinate register roller 15 which is adjustable to and fro according to arrow 14 are provided.
  • These pulling and registering rollers 13, 15 are thus located in FIG. 1, 2 in the area between the first turning bars 8 and the stationary, second turning bars 11 offset laterally against them.
  • the pulling and registering rollers 13, 15 can also be as Figure 2 shows further to act on overhung paper guide members.
  • the pull rollers 13 can be mounted on the end wall 12 just like the second turning bars 11.
  • the adjustable register rollers 15 are received on guides 16 aligned with the end wall 12 and also fastened to the machine side wall 3.
  • inlet rollers 17 offset in terms of height from one another are used above the inlet 5, over which such a strand runs in each case.
  • the inlet rollers 17 are aligned parallel to the pull rollers 13 and register rollers 15, over which the strands folded over by the first turning bars 8 also run.
  • two rows of the inlet rollers 17 flanking the center plane of the folder inlet are provided, which are approached from the right or left.
  • the inlet rollers 17 facing the pull rollers 13 are acted upon by the four lower pull rollers 13 or the register rollers 15 arranged downstream of them.
  • the inlet roller 17 of the opposite row is acted upon by the five upper pulling rollers 13 or register rollers 15, and in order to guide the relevant strands over the folder inlet instead of the second turning bars 11 to the inlet rollers 17 or the pulling and registering rollers 13, 15, parallel deflection rollers 18 Use.
  • the inlet rollers 17 provided above the folder inlet 5 are replaced by one or more former 19.
  • two former 19 are provided.
  • a cassette 20 is provided above the folder inlet 5, which contains the folder hoppers 19 and the feed rollers 17 which are required as an alternative and which can be displaced along a longitudinal guide 21 provided in the superstructure 7 in such a way that in a In the first working position, the former 19 and in a second working position, the inlet rollers 17 above the folder inlet 5 are in position.
  • the longitudinal guide 21 assigned to the cassette 20 runs, as can be seen from FIG.
  • the strands fed to the formers 19 run parallel to the longitudinal direction of the printing press.
  • the strands which are deflected by 90 ° by means of the first turning bars 8 are accordingly guided over the second turning bars 11 to bring about a further 90 ° diversion and then, as can best be seen from FIG. 2, offset relative to the second turning bars 11 in the longitudinal direction of the printing press , deflection rollers 22 arranged perpendicular to the pull rollers 13 or register rollers 15 are fed to the former 19. These deflecting rollers 22 are also overhung here.
  • a side wall 23 of the superstructure 7 running parallel to the machine side walls 2, 3 and perpendicularly abutting the end wall 12 is provided. This side wall 23 lies in FIG. 2 within the deflection rollers 18 provided for magazine production and is accordingly provided here with a passage window 24 for the strands leading to the deflection rollers 18 past the stationary, second turning bars 11 during magazine production.
  • FIG. 3 does not differ in terms of its basic structure and mode of operation from the embodiment described above with stationary second turning bars and alternatively deflecting rollers for magazine production which can be acted upon. Accordingly, the following description only refers to the existing structural deviations. the same reference numerals being used for the same parts.
  • the second turning bars 11 and an equal number of deflecting rollers 18 which can be acted upon in magazine production as an alternative to the second turning bars 11 are accommodated on a pivoting wing 26 which is pivotably mounted about a standing axis 27 .
