Definitions

  • the invention relates to the folding rollers of a device for longitudinal folding the preamble of claim 1.
  • DE 38 36 342 C2 describes a device for longitudinal folding of at least one Once the printed copy has been folded by means of a print copy between the Folding rollers pressing folding knife known.
  • the folding rollers have a first circumferential section forming the fold and subsequently one second circumferential section with recesses and residual surfaces, the The remaining areas fix the printed copy during further transport, as is then at least one folding roller except for that for the Conveyor belt system required guides with one in the longitudinal direction continuous, completely releasing the printed copy from the folding rollers Recess equipped.
  • the invention has for its object to fold a device for To create longitudinal folds according to the preamble of claim 1, which is high Folding speed enables unbalance and for processing Print copies of different section lengths are easily convertible. This object is solved by the characterizing features of claim 1.
  • the one for different section lengths of the printed copy in different Available split intermediate ring is available in conjunction with the axial Slidability of the adjacent pull ring with little effort Can be easily mounted radially on the respective folding roller. It is for high Folding speeds required freedom from unbalance of the folding rollers in any case given since both the one with the fold bar for the smallest section length equipped folding roller without intermediate ring as well as the respective intermediate ring with the section of the folded strip which is all the way apart are unbalanced.
  • the manufacturing effort for the few recesses is also Folding rollers relatively small, especially mainly with the width through cutouts equipped with axially attachable pull ring and Intermediate ring can be efficiently manufactured separately from the rest of the roller body can.
  • Fig. 1 shows a folding knife 1 of a folding drum 2 in the folding position in which it a not shown, folded at least once, in time on the folding table 3 printed copy fed and slowed down to zero stops between two with a fold bar 4; 5 equipped folding rollers 6; 7 presses. The folded printed copy is then between the folding rollers 6; 7 partially wrapping conveyor belts 8; 9 led downwards.
  • folding roller 6; 7 consists of an axis 10 with a base body 11, a centrally divided, radially attachable to the axis Intermediate ring 12 and two pull rings laterally delimiting the roller body 13; 14, of which the pull ring 13 adjacent to the intermediate ring 12 is axial is slidably disposed on the axis 10.
  • the fold bar 4 radially screwed to the base body 11; 5 continuously arranged for which the base body 11 and the intermediate ring 12 with a axially parallel groove 15 (Fig. 4) are equipped.
  • the Basic body 11 and the fold bar 4 5 annular, continuous incisions 16; 17 for guiding the conveyor belts 8; 9.
  • the folding roller 6; 7 has a first circumferential section U 1 which forms the fold of the printed copy and which is formed from the fold bar 4; 5 and in each case a first peripheral section of the pull rings 13; 14 exists.
  • a second circumferential section U 2 of the folding roller 6 which fixes the printed copy after folding during further transport; 7, which consists of the respective second peripheral section of the pull rings 13; 14 and one each axially parallel to the fold bar 4; 5 there is a second circumferential section of the intermediate ring 12 and the base body 11, which is adjacent in the circumferential direction, the diameter of the intermediate ring 12 and the base body 11 compared to the diameter of the pull rings 13; 14 on the one hand avoiding pressing and thus wrinkling of the printed copy and on the other hand ensuring its guiding during further transport is slightly reduced by a fraction of a millimeter - for example 0.2 mm.
  • At least one folding roller is provided, at least in the edge region R 1 that cooperates with the open side of the printed copy, with one completely of the folded rollers 6; 7 releasing recess Au equipped, which is in each case composed of a third peripheral portion of the intermediate ring 12 and the adjacent pull ring 13. This will damage the printed copy due to Whip effect "avoided at the particularly vulnerable corner of the open side of the printed copy.
  • the cutout Au can, however, also on the edge area R 2 cooperating with the closed side of the printed copy, as shown in dash-dotted lines in FIGS. 3, the third circumferential section of the opposite pull ring 14 and a section of the base body 11 adjacent to it are extended in order to exclude damage to both corners of the printed copy with certainty.
  • the only loose guidance of the printed copy outside the edge areas R 1 ; R 2 wrinkling in this area is not limited.
  • the folding rollers 6; 7 allow processing of Printed copies of different section lengths Al.
  • the Intermediate ring 12 and the fold bar 4; 5 in different versions with the Width B or length L corresponding to the respective section length Al interchangeable.
  • Unbalance of the folding roller 6; 7 to ensure this is with a folding strip 4, which closes on both sides with the base body 11; 5 for the smallest section length Al of the printed copy and the pull rings 13; 14, but without the intermediate ring 12 and the respective intermediate ring 12 with the proportion of the folding strip 4 based on its width B; 5 for yourself separately unbalanced.
  • the intermediate ring 12 is made for mass compensation for the recess Au Made of aluminum with a relatively low density and has this adjacent to recess Au cavities 21, which with a balancing mass 22 made of steel are filled with a relatively high density.
  • the intermediate ring 12 in its half opposite the cutout Au several the mass reducing cavities 23 (Fig. 4). With the latter cavities 24 too the respective recessed pull ring 13; 14 equipped (Fig. 5).
