Definitions

  • the present invention relates to an ink ribbon and, more particularly, to an ink ribbon which has a large resistance against hitting for printing and is capable of extending the life of its cloth.
  • the resistance against hitting for printing (hereinafter referred to as “hitting resistance” simply) is meant by the number of hits for printing characters until a hole of 0.3 mm or more in diameter is made in the hit portion of an ink ribbon on the condition that hitting for printing 10 characters on one line is repeatedly carried out with the ink ribbon kept stationary.
  • hitting resistance simply is meant by the number of hits for printing characters until a hole of 0.3 mm or more in diameter is made in the hit portion of an ink ribbon on the condition that hitting for printing 10 characters on one line is repeatedly carried out with the ink ribbon kept stationary.
  • the size of one character is 3 to 4 mm, and the number of hits is counted on a NLQ-mode printing basis.
  • endless ink ribbons and seamless ink ribbons for use with a printer or the like have employed a weave structure of plain, twill, sateen or the like.
  • Fig. 7 is an explanatory plan view of such a conventional ink ribbon
  • Fig. 8 is an explanatory sectional view of the same.
  • the conventional ink ribbon of a plain weave structure is obtained by weaving the warp 11 and weft 12 each composed of synthetic fibers such as nylon, polyester and rayon, natural fibers or the like to form a cloth and heat-cutting the cloth to a width of a desired ink ribbon.
  • the warp is meant by a yarn extending perpendicular to the advancing direction of the ink ribbon.
  • the dot pin 13 moving to the right and left is likely to scratch the warp 11 thereby exerting a substantial force thereon.
  • the warp 11 is cut off with the weft 12 possibly cut, whereby the ink ribbon is no longer usable.
  • the hitting resistance of the conventional ink ribbon depends on durability of the warp 11 and, hence, it is difficult to improve the hitting resistance.
  • an object of the present invention to provide an ink ribbon having an increased hitting resistance and offering an extended life.
  • an ink ribbon comprising warp yarns extending perpendicular to a direction in which the ink ribbon advances, and weft yarns extending parallel to the direction, wherein (1) the warp yarn is thinner than the weft yarn, or (2) picking density of the weft yarn is larger than that of the warp yarn.
  • Fig. 1 is an explanatory plan view showing an embodiment of an ink ribbon according to the present invention, wherein a plain weave structure is employed.
  • a warp yarn 1 and a weft yarn 2 are each composed of synthetic fibers such as nylon, polyester and rayon, natural fibers, or like fibers.
  • the warp yarn 1 and weft yarn 2 are woven with a usual weaving machine.
  • the warp yarn 1 is thinner than the weft yarn 2, and is preferably woven at a relatively high tension.
  • the weft yarn 2 is thick relative to the warp yarn 1, and is preferably woven at a relatively low tension.
  • the warp yarn 1 is usually 30 to 50 deniers, while the weft yarn 2 is usually 30 to 150 deniers.
  • the weft yarn 2 is about 1.1 to 3 times, especially about 1.5 to 2.2 times as thick as the warp yarn 1.
  • the warp yarn 1 is set back from the surface of the ink ribbon in section, as shown in Fig. 2. Consequently, the probability that a dot pin 3 comes into direct contact with the warp yarn 1 is reduced and, hence, the hitting resistance of the ink ribbon can be improved.
  • such probability can also be reduced by making the picking density of the weft yarn 2 larger than that of the warp yarn to increase the proportion of the weft yarn 2 to the whole woven cloth.
  • the picking densities of the warp yarn 1 and weft yarn 2 are usually 100 to 180 yarns/inch and 110 to 500 yarns/inch, respectively.
  • the picking density of the weft yarn 2 is about 1.1 to 3 times, especially about 1.5 to 2.2 times as large as that of the warp yarn 1. In this case too, the probability that the dot pin 3 comes into direct contact with the warp yarn 1 is reduced and, hence, the hitting resistance of the ink ribbon can be improved.
  • Figs. 3 and 4 are explanatory plan view and explanatory sectional view, respectively, of another embodiment of an ink ribbon according to the present invention.
  • a twill weave structure is employed.
  • this embodiment is of a sectional structure wherein the areal proportion of the weft yarn to the surface area of the ink ribbon is large as compared with the conventional ink ribbon. Therefore, the probability that the dot pin comes into direct contact with the warp yarn is reduced.
  • Figs. 5 and 6 are explanatory plan view and explanatory sectional view, respectively, of still another embodiment of an ink ribbon according to the present invention.
  • This embodiment employs a sateen weave structure and exhibits an effect similar to those of the preceding embodiments.
  • ink ribbon of the present invention has been described by way of the embodiments respectively having plain, twill and sateen weave structures, the present invention is not limited to such embodiments and can, of course, employ other weave structures.
  • the proportion of a weft yarn in the surface area of the ink ribbon is increased by using a warp yarn thinner than the weft yarn or making the picking density of the warp yarn smaller than that of the weft yarn. For this reason, the probalility that a dot pin comes into direct contact with the warp yarn can be remarkably reduced as compared with the conventional ink ribbon. Thus, it is less likely that a dot pin moving to the right and left scratches the warp yarn thereby exerting a large force thereon. Hence, the hitting resistance can be greatly improved.
  • the ink ribbon can offer an extended life and, further, if it is supplied with ink by reinking, the life thereof for printing can also be made longer than that of the conventional ink ribbon.
