Definitions

  • the present invention relates to a folding table according to the preamble of claim 1.
  • Corner fold devices are known which are adapted to fold a flat product, such as a sheet or a signature which has been printed in an offset rotary press. Such a device is known to US 2005/90932 .
  • DE 26 38 784 describes a transfer table.
  • These square fold devices include a folding table, folding rolls and a folding blade.
  • the folding blade is used to push the flat products through a slot in the table in a gap formed by the rollers.
  • the square bend device is provided with flat product conveyor belts for routing on the bending table.
  • the conveyor belts are driven by the product to be folded in a direction transverse to their direction of conveyance. As a result, the belts overlap transversely and create jams.
  • the object of the invention is to increase the time of availability of a folding device, in particular of a right-angle fold device.
  • the object of the invention is a folding table, comprising the features of claim 1.
  • the folding table comprises one or more of the features indicated in the dependent claims.
  • the square folding device 2 comprises a folding table 4, a folding blade 6, and two folding rollers 8, 10.
  • the folding blade 6 is movable back and forth in a folding direction DP and is arranged on one side of the folding table 4.
  • the two folding rollers 8, 10 have parallel axes and form a folding interstice between them.
  • the square crease device 2 comprises lower conveyor belts 12 and upper conveyor belts 14.
  • the conveyor belts 12 and 14 are adapted for conveying flat products to be folded 16, such as signatures or sheets, onto the folding table 4 according to a direction of routing D and in a direction of routing S (see Figure 2 ).
  • the conveyor belts 12 and 14 extend parallel to the conveying direction D and are driven in the direction of conveyance S.
  • the folding table 4 has a folding face 18 facing the folding blade 6 and a lower face 20 facing the folding rollers 8, 10.
  • the folding table 4 defines a folding slot 22 through which the products to be folded 16 are pushed by the blade 6.
  • the folding slot 22 extends parallel to the routing direction D.
  • the folding table 4 is provided with means 24 for guiding the lower conveyor belts 12 in the conveying direction D. These guide means 24 are adapted to oppose a deflection of the lower conveyor belts 12 towards the slot of the conveyor. folding 22, therefore transversely to the direction D, when the product to be folded 16 is pushed by the folding blade 6 through the folding slot 22.
  • the folding table 4 comprises a base body 26 and guide ribs 28 extending in the direction of routing D.
  • the base body 26 has a general parallelepiped shape.
  • the ribs 28 are arranged on the base body 26 and form the guide means 24.
  • the ribs 28 and the base body 26 form the folding face 18.
  • Two adjacent guide ribs 28 form between them a guide channel 30 (see FIG. Figure 3 ) in which extends either a lower conveyor belt 12 or several lower conveyor belts 12. Furthermore, the conveying channel 30 closest to the folding slot 22 receives two lower conveyor belts 12.
  • the two belts conveying 12 in the same conveying channel, on both sides of the fold blade 6, are used for better guidance and better maintenance during the fold phase, notebooks, signatures, sheets, in particular narrow width (small width paper strip).
  • Each guide rib 28 is thus arranged between the associated lower conveyor belt 12 and the folding slot 22 so as to guide the belt 12 during folding.
  • the lower conveyor belts 12 have a first height H1, measured perpendicular to the table plane P, and each guide rib 28 has a second height H2, also measured perpendicularly to the plane P of the table.
  • the second height H2 is either less or identical or is strictly less than the height H1 so as not to disturb the folding of the product to be folded.
  • the guide rib 28 has a height H2 which is between 0, 5 and 0.8 times the first height H1, and thus contributes to supporting the product to bend 16 during the routing.
  • the base body 26 and the ribs 28 are provided with an anti-friction coating 32, which is advantageously made of chromium. This coating 32 promotes the sliding of the conveyor belts 12 and the products to be folded on the table 4.
  • the second height H2 is measured from the free surface of the coating 32 of the base body 26 to the free surface of the coating 32 of the rib 28.
  • the guide ribs 28 are made in one piece and in particular in one piece with the base body 26, which reduces the manufacturing costs of the folding device.
  • the base body 26 and the ribs 28 are made for example of steel or aluminum.
  • the folding table according to the invention reduces with simple and economical means the risk of jamming of the bending machines and thus increases the reliability of the folder.
  • conveyor belts 12, 14 can be replaced by other conveying elements.
