Definitions

  • the invention relates to a type tape for a type tape printer.
  • Usual type tape printers e.g. the IBM type tape printer 3288, 3289) have an all-round type tape, which presents itself as a steel tape with raised print types and tact marks etched out by photochemical means.
  • the following arrangement of the steel strip in relation to a pressure abutment and the record carrier and ink ribbon to be considered is decisive for the printing of a character:
  • the smooth back of the steel strip moves past the pressure abutment.
  • the ribbon and the recording medium are located in front of the front of the ribbon with the raised printing types.
  • the character imprint in a certain printing position is effected by a printing hammer, which strikes the recording medium and presses it against the ink ribbon, the type of steel ribbon to be printed and the platen.
  • Such a polishing process turns out to be very complex and expensive and is also very difficult to control. In other words: the polishing process often does not lead to the desired result.
  • Fig. 1 is shown in a sectional view how the type tape 1 is arranged opposite the platen 2, the ink sheet 3 and the recording medium 4 and the print hammer 5.
  • the hammer 5 strikes against the recording medium 4, the ink ribbon 3, the raised etched print type 6 on the front side 1-1 of the type tape 1 and presses the type tape 1 with its rear side 1-2 against the pressure abutment 6.
  • the type ribbon 1 moves in the direction perpendicular to the plane of the drawing, while the ink ribbon 4 remains relatively stationary.
  • there is a strong lateral stress on the ribbon caused by the sharp printing type edges of the character 6. This stress can ultimately lead to destruction of the ribbon tissue, so that - as already indicated - when using "untreated" type ribbons, the ribbons must be replaced frequently.
  • Fig. 2 is a partial perspective view of the front 1-1 of the type tape with raised etched out types (6-1, 6-2) and timing marks (6-1-1, 6-2-2) are shown.
  • Excerpts of types H (6-1) and I (6-2) can be seen on the front 1-1 of volume 1.
  • the timing marks assigned to these printing types (6-1-1 and 6-2-2) are also etched out. They are used to synchronize the pressure control.
  • FIG. 3 shows a sectional illustration of the type tape along the section line A-A according to FIG. 2. It can be seen that the type and timing mark edges (7) are extremely angular, which ultimately has a destructive effect on the ink ribbon (this sharpness of the printing types naturally also applies to the cutting direction indicated in FIG.
  • PTFE polytetrafluoroethylene
  • a and B show schematic sectional representations of a type tape before and after use, which has been coated with a PTFE-containing material.
  • the section line would correspond to B-B of FIG. 2 if the type tape shown there had been coated.
  • the metallic cut surface is heavily hatched, while the cut surface is only slightly hatched by the layer 12 containing PTFE.
  • the PTFE-containing material is not only deposited on the locations 8 between the type elevations 6-1 and clock mark elevations 6-2, but also at locations 9 on the type surface to be printed, as well as embankment-like at locations 10 on both sides of the types - or time stamp surveys.
  • the material containing PTFE deposited in the areas 9 is rubbed off in the shortest possible time (with high printing performance after a few cycles); it also partially attaches to the embankments 11 (FIG. 4B). From this representation it can be seen that, compared to the representation according to FIG. 3, the effective type and clock mark edges are no longer so sharply formed (embedded in material containing PTFE) and therefore can no longer have such a destructive effect on the ribbon fabric.
  • the PTFE-containing layer must also contain certain additives (resins) that guarantee the abrasion resistance of the layer.
  • resins such admixtures for achieving a higher abrasion resistance are commercially available (eg as "TEFLON S", registered trademark of the Dupont company).
  • the application of pure PTFE required e.g. B. for reasons of liability on the base material before outgoing sandblasting and a high temperature. However, both of these boundary conditions would not be acceptable, particularly for type bands.
  • the layer containing PTFE is applied by spraying with a subsequent moderate heat treatment.
  • the contamination occurring in the area of the type tape is reduced, since fewer type fibers and colored particles are entrained by the type tape in coated type tapes and are only transported to a small extent due to the anti-adhesive properties of the layer surface.
  • the coating on the front of the type tape also leads to a reduction in wear on the surface of the type tape, which is due to the formation of a thin film of the PTFE, which is also to be understood as a dry lubricant, both on the type surfaces to be printed and on the fabric of the ink sheet.
