Definitions

  • the invention relates to a form separation device for perforated continuous forms with tear-off perforations, which can be used on typewriters and printers, in particular on matrix printers, consisting of a form guide with tractors and tractor flaps and a guide grill located above the machine housing.
  • Such form separating device serve to tear off the finished or finished printed single-layer or multi-layer forms by hand and without a tear-off rail, which complicates the design of a typewriter or a printer and makes it more difficult and less convenient to use.
  • the structure of such a form separator is also designed for processing the forms in a stretched state.
  • the stretched state is advantageous when tearing off, because then in the case of multi-layer forms, the cover sheet to the end sheet is not displaced by unevenly long distances.
  • Formufar entry with tractors and tractor flaps are known (DE-OS 30 36 642).
  • the tractor flaps can be swiveled out to insert the perforated form sheets into the paper guide. After the paper webs have been inserted, the pins on the tractor guide the paper and transfer the required feed force to the paper web.
  • This type of paper web guides requires a gap between the tractor flap and the paper surface, which partly ensures that there is no braking friction on the paper web by contact with the tractor flap, that only the pins in the edge perforation transmit their full feed force and that one or multilayer paper webs can be processed. Such multi-layer paper web completely or partially fill the gap.
  • the invention has for its object to separate a finished or finished printed continuous form using the perforation (so-called.quick tear), without the arrangement of a tear-off rail complicating the structure of the machine, which is to go as far as the tear-off rail dispense.
  • a clamping drive is arranged on the outside of the machine housing, that the clamping drive is connected to a clamping shaft running on the front of the operator and that the clamping shaft is assigned clamping elements by means of which the continuous form in the area of the tear-off perforation for the tear-off process can be firmly clamped.
  • a quick disconnect is particularly z. B. with tickets of great advantage.
  • the transfer of the clamping force is supported by the fact that pressure pieces are inserted in the tractor flaps and that the pressure pieces are operatively connected to the clamping shaft.
  • the clamping element consists of a profile rail fastened to the clamping shaft, which in the clamping position is opposite an anvil bar, which forms a support for the continuous form on the machine housing.
  • the clamping shaft is rotatably mounted in a mounting housing and that an automatically resetting operating lever is attached to at least one end of the clamping shaft.
  • the form separator can therefore also be retrofitted to office machines.
  • the arrangement of the controls and the accessibility of the paper guide are further favored in that the mounting housing and the length of the clamping shaft correspond to the full width of the typewriter or the matrix printer.
  • the attachment housing is made of transparent material.
  • the form separator shown can be used for all writing office machines, such as. B. typewriters, printers, matrix printers and the like.
  • NEN endless forms 1 with perforations 2 are used.
  • Such endless forms 1 are each divided by tear-off perforations 3 into identical or different forms with a repeating text or delimited from one another.
  • the continuous form 1 is advanced line by line or at greater intervals by two tractors 4 assigned to the edge perforations 2, the tractors 4 being equipped with tractor flaps 4a (FIG. 3).
  • the continuous form 1 is guided outside the tractors 4 through the guide grille 6 fastened to the machine housing 5, the printed continuous form 1 leaning against the guide grille 6 at an inclination of 10 ° away from the operator and not tipping against the operator, moreover maintains an approximate flat position and is therefore also easy to read in the machine and maintains a favorable starting position in the tear-off process to be described.
  • the mounting housing 7 is detachably placed on the machine housing 5 and can be removed in order to insert the continuous form 1 with its beginning into the tractors 4.
  • the insertion takes place by rotating the platen roller 8 with the attachment housing 7 removed.
  • the platen roller motor (not shown) drives the drive shaft 11 for the tractors 4 via the transmission 10, which consists of several gear wheels, which in turn each have a spiked belt 12 the pins 12a to transport the continuous form over the edge perforation 2.
  • a clamping drive 13 is provided according to FIG. 3, after its actuation the tractor flaps 4a hold the continuous form 1 so that it can be effortlessly moved with one hand and without a tear-off rail in direction 9 (FIG. 1) can be separated.
  • the clamping drive 13 can be actuated by means of the clamping shaft 16 running on the front of the operator 15, the clamping shaft 16 advantageously having a round profile 16a flattened on one side, the rotation of which, by means of resilient operating levers 17 fastened to the ends 16b and 16c, exerts the compressive force on the pressure pieces 14 . While the operating lever 17 is turned with one hand, the form can be separated with the other hand in a quick tear movement.
  • the clamping shaft 16 is supported in rotary bearings 18 which are located on the mounting housing 7. Due to the full extension of the clamping shaft 16 over the operator front 15, the operating levers 17 are advantageously located on the end faces 5 a of the machine housing 5.
  • the clamping force for tearing off at the tear-off perforation 3, in particular for multi-layer continuous forms 1, is further increased by (FIGS. 4 and 5) the clamping shaft 16 being combined with a profile rail 16d and an opposite anvil bar 5b being present on the machine housing 5, on which in FIG Clamping position, the profile rail 16d clamps the continuous form 1 and thereby replaces a tear-off rail.
  • the operating lever 17 is advantageously arranged projecting to the rear (FIG. 4).
