Definitions

  • the invention relates to an endless arrangement of form sets according to the preamble of claim 1.
  • the impact of workplace printers is generally sufficient for six to sevenfold sets.
  • the form guide In the form guide, the form set is usually drawn in via spiked tractors, directed around a platen roller at the printing point and led out at a different point by a spiked tractor.
  • the angle of the deflection between the two tractor guides is sometimes over 180 °. Due to this strong deflection, the lower paper web lying against the platen roller runs a shorter distance than the upper webs of the form set.
  • the endless webs are all made of the same length for manufacturing and measuring reasons, the lower webs move so far after a few form lengths that the edge holes are covered and the form set jumps out of the tractor guide.
  • a bead can also form on, in front of or behind the platen roller, which staples the webs and causes them to run sideways.
  • a first, obvious option is to use only form sets with a small number of copies.
  • the shift explained above is insignificant; in the case of two breakthroughs, it is just bearable under favorable conditions.
  • the obvious disadvantage of this solution is that one or two copies are rarely sufficient.
  • this multiflex stapling does not prevent moving, but only provides a somewhat greater resistance. Often you have to attach the Multiflex stapling again in the opposite direction. This then reduces the shift even further and prevents jumping out of the form guide; the above-mentioned bulge and the resulting shift in the print image remain. There are also wrinkles that affect the appearance and the
  • carrier sheet sets consist of an endless carrier web, to which individual sentences are glued. This prevents bulging.
  • the disadvantage of a shift of the print image to the one below the other beating remains however.
  • the carrier tape sets can only be produced with such large stand tolerances in the print that a division of the pre-printed area by lines is forbidden, unless tolerances of ⁇ 2 mm or more are available.
  • the invention is therefore based on the object, while avoiding the shortcomings described, to form an endless arrangement of form sets in such a way that the formation of a bulge in the lettering in the printer is avoided even when there are a plurality of webs arranged one above the other, no shifting of the print image occurs and also at Using an easily releasable stapling (like the crimplock stapling) there is no risk of stapling in the printer.
  • V d.U.K + 2nd.U. (1 E -K), r
  • d thickness of all webs in the form set from the first to the last but one web (in mm)
  • V difference in length between the top and bottom lanes (in%)
  • K coefficient of friction (can take values between 0 and 1)
  • the sheets arranged one above the other are stapled in such a way that - with uniform distribution of the entire length difference over the individual form sets - the dividing lines between successive form sets for all sheets lie one above the other.
  • the above-mentioned clamping length E is to be understood as the length of the form web clamped in the printer, starting from the point at which the webs have to lie one above the other for the first time to the point at which this must be the last case.
  • length is to be regarded as the clamping length in the different types of form guides.
  • the wrap U (expressed in% of 360 °) in the above formula is the angle which is formed between the point of first contact of the form web with the platen roller and the point of last contact.
  • the coefficient of friction K can take values between 0 and 1 depending on the conditions. 1 extremely high friction (stationary platen, fixed stapling, rough papers) and 0 extremely low friction (moving platen, without stapling, extremely smooth papers).
  • the coefficient of friction K is taken from tables that were determined by tests.
  • the lengthening is greater, the smaller the clamping length and the radius of the platen and the greater the wrap of the platen and the thickness the papers is.
  • the extension is also greater the smaller the coefficient of friction K to be taken into account.
  • the variation of the length of the individual webs provided according to the invention does not interfere with the stacking of the form sets in the zigzag stack.
  • the change in length is compensated for in each outer fold.
  • a certain problem is the gathering of the webs in the production of the endless arrangement of form sets and the attachment of the set connection (stitching on the edge of the form).
  • An expedient embodiment of the invention therefore relates to a device for stapling the webs of the endless arrangement of form sets according to the invention.
  • This device is characterized by the features of claim 2.
  • FIGS. 1 and 2 are schematic diagrams for explaining the endless arrangement of form sets according to the invention.
  • FIG. 3 shows a schematic diagram of various form guides in workplace printers
  • FIG. 4 shows a schematic of a device for stapling the webs of the endless arrangement of form sets according to the invention.
  • 1 shows an endless arrangement 1 of form sets according to the invention before stapling. It consists of a plurality of continuous webs 2a to 2k arranged one above the other, the thickness being calculated from the uppermost web 2a to the second-lowest Lane 2i is designated d.
  • the length of the individual tracks 2a to 2k is stepped uniformly, being between the uppermost, longest track 2a and the lowest, shortest
  • Lane 2k there is a percentage difference in length V.
  • FIG. 2 illustrates the endless arrangement 1 'in the stapled state.
  • the individual form sets are labeled 1a to 1m, the dividing lines between successive form sets are labeled 3a to 3n.
  • the webs 2a to 2k arranged one above the other are stapled such that the
  • Separation lines 3a to 3n between successive form sets for all lanes lie exactly one above the other. This means that the entire length difference V of the form set (see Fig. 1) was evenly distributed to the individual form sets 1a to 1m during stapling. Since the length difference V is of the order of a few percent, it cannot be seen in the schematic illustration in FIG.
  • 3a to 3d form guides with tractors 4, pressure rollers 5 and pressure rollers 6,
  • Fig.3a 180o a pressure roller fixed b pressure roller movable
  • Fig. 4 illustrates in a schematic form
  • Device for stapling the webs of an endless arrangement of form sets contains a support roller 8 partially wrapped by the endless arrangement, with which a stitching roller 9 interacts. Furthermore, two transport elements 10, 11 in the form of spiked wheels are arranged on the inlet and outlet sides of the support roller 8. These transport members 10, 11 are pivotable in the direction of the double arrows 12, 13, so that their relative position or their distance can be adjusted. As a result, the angle at which the endless arrangement 1 wraps around the support roller 8 can be set to the desired value.
  • the webs 2a to 2k running in through the transport member 10 are stapled on the edge of the form by the stapling roller 9 and placed in a zigzag stack 14 after the transport member 11.
  • the wrap angle of the support roller 8 is adjusted by means of the adjustable transport members 10, 11 so that the dividing lines between the successive form sets for each web lie exactly one above the other .
  • the printing press is set precisely to the form length of the individual web (when the webs 2a to 2k of different lengths later lying one above the other are thus printed, one is carried out Correction of the press setting).
  • This can be done in a simple manner, for example by means of a measuring rail of approximately 3 m in length made of metal, which contains pins at one end for receiving the edge perforation and at the other end after exactly 10 pre-printed forms at a height of 12 "(standard format) a scale that is ten times extended , on which the length can then be read.

Abstract

Disposition sans fin de liasses de formulaires, où la longueur des différentes feuilles superposées est graduée régulièrement, une certaine différence de longueur existant entre la feuille supérieure la plus longue et la feuille inférieure la plus courte. Cela permet d'éviter les difficultés (formation de bourrelets, dégrafage, sortie du guide de formulaires) qui survenaient jusqu'à présent lorsque l'on remplissait des liasses de formulaires au moyen d'une imprimante de table.
