Definitions

  • the invention relates to a folding apparatus according to the preamble of claim 1.
  • a glueing device which is arranged between knife cylinder and a collecting cylinder.
  • the glueing device is controllable in such a way that sections which come to rest on the collecting cylinder in collecting mode are glued together before they are transversely folded over a folding jaw cylinder and removed.
  • DE 198 54 053 A1 is a guide device for sheets in a printing unit of a sheet-fed printing machine disclosed. It is arranged in addition to two cylinders forming the printing nip and serves to guide the sheets when entering or leaving the printing nip. It has a multiplicity of openings through which air can flow, for example, bores or porous material, inter alia.
  • the DE 198 29 095 A relates to a sheet guiding device in the gore-shaped input and output region of the printing nip of a sheet-fed printing machine, which is to ensure a concern and thus a smooth running of the sheet in the area pressure point.
  • a housing of the sheet guiding device has at its the sheet-guiding cylinder opposite guide surface of porous, air-permeable material.
  • the invention has for its object to provide a folder with a low-pollution sizing.
  • a sizing device on the circumference of the collecting cylinder following the expiring gusset (but before the place of product intake) is a particularly low-pollution sizing feasible.
  • this region has a guide element, advantageously a non-contact, air-blown guide element, in particular with the formation of microapertures.
  • the sizing can then take place, for example, by an interruption or a recess in the guide element.
  • the folding apparatus shown in a simplified section in Fig. 1 comprises a first cylinder 01, in particular a folding blade cylinder 01, a second cylinder 02, in particular jaw cylinder 02, and a guide element 03, in particular Rescueleitelement 03, in the Meetingzwickel the product transfer gap between the two cylinders 01 ; 02 is arranged.
  • folding blades (not shown) extending from the folding blade cylinder 01 when passing through the product transfer nip (not shown) press a section 04 to be folded, e.g. B. to be folded product section 04 of a printed product, in a jaw (not shown) of the jaw cylinder 02, where it is trapped and forwarded.
  • the further rotation of the two cylinders 01; 02 causes between the surface of the folding blade cylinder 01 and the product section 04, which is deducted from this, a gap 06 is formed, in which the air pressure from the outside must flow to the outside. This negative pressure hinders the removal of the product section 04 resting against the folding blade cylinder 01.
  • the product guiding element 03 is used inter alia. to erfeichtem the removal of this leading part of the product section 04.
  • the surface of the guide element 03 has openings 10, in particular micro-openings 10, through which in operation from an internal hollow or interior 07, z. B. a chamber 07, in particular pressure chamber 07, under pressure against the environment fluid standing, z. As a liquid, a gas or a mixture, in particular air, flows. In the figures, a corresponding supply of compressed air into the cavity 04 is not shown. A fluid cushion is formed by the fluid flowing through the micro-openings 10, thereby preventing the product section 04 from striking against an otherwise common product guide plate.
  • the guide element 03 has the micro-openings 10 at least on a side of its surface facing the product section 04. However, it can also have the openings 10 on other sides not facing the product section 04 or else consist entirely of a material comprising the micro-openings 10 on its longitudinal section cooperating with the product section 04 and form the cavity 07.
  • This simplest embodiment for the arrangement of the openings 10 is made possible by the formation of the openings 10 as micro-openings 10, since hereby a thinner but more homogeneous air cushion created while a required or resulting volume flow and thus a leakage current on the "open" side considerably reduced is.
  • the high resistance of the micro-apertures 10, in contrast to large-cross-section apertures, causes "not capping" a portion of apertures 10 to result in some sort of short-circuit current. In the total resistance of the falling over the openings 10 partial resistance receives an increased weight.
  • the formation of the wall of the guide element 03 in the region of the micro-openings 10 can be carried out in different ways, which is indicated in Fig. 1 with "detail A, B" and shown in Fig. 2 and 3 as a detail for the two versions.
  • FIG. 2 for the micro-openings 10, these are in the form of open pores on the surface of a porous, in particular microporous, air-permeable material 09, eg. B. of an open-pore sintered material 09, in particular of sintered metal 09, is formed.

  • the material 09 is formed with an irregular, amorphous structure.
  • the cavity 07 of the guide element 03 may, at least on its cooperating with the product section 04 area, essentially alone from a Cavity 07 formed on this side final body of porous solid material (ie without further load-bearing layers of appropriate strength) may be formed.
  • This substantially self-supporting body is then formed with a wall thickness of greater than or equal to 2 mm, in particular greater than or equal to 3 mm.
  • the guide element 03 a solid, at least partially air-permeable support 08, in particular support body 08, on which the microporous material 09 is applied as a layer 09.
  • Such a carrier body 08 can be acted upon with compressed air, which flows out of the carrier body 08 through the microporous layer 09 and thus forms an air cushion on the surface of the guide element 03.
  • the porous material 09 is thus not designed as a load-bearing solid body (with or without frame construction), but as a coating 09 on a feedthroughs 15 or through-openings, in particular metallic, carrier material.
  • the carrier body 08 Under "non-bearing" layer 09 i.V.m. the carrier body 08 is - in contrast to known for example from the prior art "supporting" layers - understood a structure, wherein the layer 09 is supported over its entire layer length and total layer width each on a plurality of support points of the support body 08.
  • the carrier body 08 has z. B. on its co-operating with the layer 09 width and length respectively a plurality of non-contiguous passages 15, z. B. holes 15, on.

Particularly advantageous is the air outlet of 3 to 7 standard cubic meters per m 2 .
  • Air that has passed through one of the holes 15 of the support body 08 tends to distribute in the pores of the microporous layer 09 both to the surface and sideways, parallel to the surface. Assuming that the flow resistance in the microporous layer 09 is isotropic, the air passing through a bore of the support body 08 is also isotropically distributed in the layer 09. In order to provide a homogeneous gapless air cushion on the surface of the layer 09, it must Air leak on the entire surface, even in those areas under which there is an impermeable surface area of the support body 08. For this purpose, the thickness of the microporous layer 09 may be at least as great as an average distance between adjacent bores 15 on the surface of the carrier body 08.
