Definitions

  • the invention relates to a tear-off device with a tear-off rail for form webs, which extends transversely to the direction of transport.
  • tear-off rails are also known, for example in the case of adding machines, typewriters, teleprinters, automatic text machines or the like, which allow an endless form web to be torn off along a tear-off rail extending transversely to the transport direction of the form over the form web.
  • the tear-off rail is between two. Swivel levers attached, which are mounted on an axis behind the paper roller. On the swivel levers, tongues are provided at the front which carry pressure rollers, as is customary in typewriters for the upper pressure rollers. The distance between the swivel levers determines the width of the form to be inserted. The adjustability of the distance between the swivel levers is limited. Moreover, it is necessary with this tear-off device to pivot the pressure rollers with the tear-off rail to insert the form web, because the clean insertion of a plurality of forms to be labeled between the pressure rollers in contact and the platen roller is not possible.
  • the object of the invention to provide a tear-off device for form webs which does not hinder the insertion of the form webs in any way, which therefore does not need to be pivoted away for the insertion of the form webs and which can be used for any possible form web width.
  • the tear-off device should also be designed in such a way that the forms are not relative to the printing unit during the tear-off process resp . can move the printing document.
  • the invention is based on a tear-off device in the form of a flap which is provided with a tear-off rail at the longitudinal edge facing away from its pressure point and which is provided with a holding rail or retaining lugs for the form web during the tear-off process at its longitudinal edge facing the pressure point and which is characterized in that the bearing and pivot points of the flap in the context of the printing device between the two longitudinal edges, so that the flap pivots through the tearing process from the normal position in which the retaining rail or tabs are ineffective into the tear-off position in which the holding rails or lugs are effective.
  • the storage of the tear-off device By designing the storage of the tear-off device according to the invention, it is possible to introduce form webs of any width without the tear-off device having to be pivoted away by simply inserting the form webs between corresponding guide slots.
  • the tearing-off device In the tear-off process itself, the tearing-off device is pivoted in such a way that the parts of the form web remaining in the machine are then automatically clamped, so that it is not possible to move it relative to the printing unit.
  • an elastic friction support is provided as an abutment either on the frame part guiding the form web or on the holding rail or on the holding lugs, which compresses when the form web is pivoted and thereby compresses it Keeping the form web relieved.
  • Abutment also preferably consists of several parts which can be moved on a guide axis and which are adjusted to the width of the form web.
  • Figure 1 is a representation of the tear-off device in the rest position
  • Figure 2 is a representation in the pivoted working position '.
  • FIG. 2 shows the print head 1, which uses letters or other printing elements to print letters and numbers on a printing pad 2.
  • the form web is moved between two guide parts 9 and 10 and by means of a funnel 11, which is delimited on the one hand by the guide part 10 and on the other hand by a frame part 12, the tear-off device 13.
  • the guide parts 9 and 10 can also be connected to one another and form the side edge guide for the form web 8. In this case, the parts on the axis 23 can be moved together.
  • the form web 8 leaves the printing device between a housing part 14 and the tear-off device 13.
  • the tear-off device 13 consists of a flap 15 which on the one hand has a tear-off rail 16 designed as a sharp edge and on the other hand a holding rail 17. Instead of the holding rail 17, holding lugs could also be provided.
  • the flap 15 is connected on both sides via bolts 18 to holding parts 19 which are pivotally mounted on further bolts 20 on the frame part of the machine, not shown.
  • This type of mounting of the flap 13 has the advantage that when the flap is pivoted the paper web does not move relative to the tear-off slide ne 16 panned.
  • An abutment 21 in the form of an elastic friction pad is also arranged on the guide part 10.
  • a sealing strip 22 is provided on the frame part 12, which is used for noise insulation.
  • the guide part 10 can be connected to the guide part 9 and laterally adjustable on an axis 23 in order to be able to be adjusted to different form web widths.
  • an abutment 21 which extends over the entire width of the web
  • two abutments which only engage laterally on the form web are cheaper because the holding rail 17 may bend when pressed and then may no longer lie laterally.
  • the tearing device 13 is in the position shown in FIG. 1.
  • the form web 8 is loosely guided between the guide parts 9, 10 and the frame 12, 14 and the tear-off device 13. If a form web is to be torn off, for example along the weakening lines normally provided in these form webs, then. this form path is gripped between the thumb and index finger and pulled to the right in FIG. 2.
  • the flap 15 pivots and the holding rail 17 comes into engagement with the form web 8 and the abutment 21.
  • the part of the form web 8 remaining in the machine is thus fixed in the printing device between the transport rollers 3 and 4 and cannot be warped. It is now possible, by exerting a greater pull on one side edge of the form web, to tear off the part of the form web that has emerged from the device along the tear-off rail 16.
