Definitions

  • the height of the exit slot of the paper web guide above the base can be changed, for which purpose the length of the vertical section of the paper web guide is changed in order to adapt to the different height of the entry slot for the paper web in different printers. It can also be created by arranging paper web guides in different levels, to feed the paper web from the front or from the rear, depending on whether the paper web guide having the feed slot at the front or the paper web guide having the feed slot at the back is used. Frictional forces act on the paper web, which has to be moved through the space between the paper web guides and fed to the feed elements of the printer during threading, and are exacerbated when the paper web is deflected from the horizontal direction of movement.
  • the paper web undulates between the point of application of the feed forces and the insertion slot into the paper web guide, which leads at least to transportation difficulties, if not to a prevention of transportation and to a crumpling of the paper web.
  • the feed forces must be applied at a relatively large distance from the insertion slot, since this is covered by the base of the printer.
  • the guide parts are adjustable in length, for example by telescoping into one another, usable intermediate parts or the like.
  • the guide can be adapted to practically any length of the support for the printer, thereby ensuring that the insertion slot is actually freely accessible, preferably at the end, ie to lie in the area of the free edge of the support comes, so that it is sufficient to insert the end of the paper web into the insertion slot of the guide facing the operator, preferably at working height (sitting position), and to advance it by means of forces applied by the operator's fingers near the insertion slot until the free end of the Paper web protrudes at the other end of the guide and thereby already enters the feed area of the printer in order to be then pulled further by it.
  • the light distance between the guide parts by adjusting means such as adjusting screws, cam levers or the like. is adjustable.
  • the guide parts or openings or the like are formed parallel to the feed direction of the paper web. for manual paper web transport. In this way the threading of the paper web between the guide parts and the transport to the printer can be further improved.
  • the security that can be achieved by the measure according to the invention when feeding the paper web to the printer table also allows, in a further embodiment of the invention, to arrange a plurality of guide parts, essentially parallel to one another, in order to be able to guide one of different paper webs to the printer in each guide thus formed, each of which Guide with retaining elements, e.g. clamps, clamps or the like. is provided for the end of the paper web not required.
  • the paper web already threaded in the uppermost paper web guide is not a hindrance to the introduction of a further paper web into an underlying paper web guide
  • the guide lying under the top paper web guide or the guides lying there are laterally open. This configuration enables a new paper web to be inserted from the side, so that the uppermost paper web guide does not constitute an obstacle to the insertion of paper webs located below.
  • the guide located under the top paper web guide or the top paper guide or the bottom guides is or are arranged so that they can be moved laterally around a new paper web next to the to be able to insert a stationary paper web from the side.
  • the guide parts are mounted on the table in a height-adjustable manner, in order to - as is known per se - the Bring the printer-facing slot to different heights. As soon as the slot has reached the correct height, the guide is fixed opposite the printer table or the surface on which the printer is standing.
  • the height adjustability can be achieved in that the guide parts in the area of the paper insertion slot in a pivot bearing on Table stored and can be locked in any angular position relative to the table level, for example by clamping.
  • a mechanical drive e.g. in the form of drivable rollers, grippers or the like.
  • the drive having a freewheel position, e.g. in such a way that the drive is brought into and out of engagement with the paper web in order to carry out the paper transport through the printer, or the drive for the transport of the paper web can be switched off so that the paper web can also be pulled out of the paper web guide by hand.
  • a mechanical drive e.g. in the form of drivable rollers, grippers or the like.
  • the drive having a freewheel position, e.g. in such a way that the drive is brought into and out of engagement with the paper web in order to carry out the paper transport through the printer, or the drive for the transport of the paper web can be switched off so that the paper web can also be pulled out of the paper web guide by hand.

  • FIG. 4 shows a printer 1 with the feed opening at the rear, in the case of a table 2 with an opening 4 as in FIG. 1.
  • the guide 6 with its parts 7, 8 is each in the form of a J; the longer legs 9, which are fixed on the underside of the table 10, are connected to the shorter legs 11 via web parts 15.
  • the guide 6 can have a pivot bearing 16 at the free end of the legs 9 in order to adapt the guide, namely its exit slot, to different heights of the feed opening of the printer 1.
  • the other end of the legs 9 can be fixed in the height position required in each case by means of locking elements, in the example shown a screw spindle.
  • a guide according to FIG. 4 is also provided in the arrangement according to FIG. 6, the longer legs 9 of the guide 6 extending between the upper side 3 of the table 2 and the lower side of the printer 1 and ending with the front wall thereof.
  • the guide 6 can be provided in a recess 14 in the table 2, analogously to FIG. 3.
