Abstract

Whenever possible, it Is desirable to increase the life of an ink ribbon used in printing applications. One significant reason for the failure of printer ribbons is that the ribbon material itself is destroyed by the constant pounding of the print mechanism against the ribbon. This is particularly true in wire matrix printers. The plastic strands which constitute the ribbon material are cut by the action of the print wires.

Improve Life Ink Ribbons

Whenever possible, it Is desirable to increase the life of an ink ribbon used in printing applications. One significant reason for the failure of printer ribbons is that the ribbon material itself is destroyed by the constant pounding of the print mechanism against the ribbon. This is particularly true in wire matrix printers. The plastic strands which constitute the ribbon material are cut by the action of the print wires.

Referring to the figure, a laminate composed of an ink ribbon and a plastic tape bonded to the ribbon with an adequate adhesive may be fabricated to increase the life of the ribbon. The tape may be fabricated of a suitable tough material such as a polyethylene terephthalate film. The tape may have an adhesive backing to facilitate manufacturing of the composite. The use of the laminate, as shown in the figure instead of a present ribbon improves the resistance of the composite to failure. An additional laminate will increase the stiffness of the part, which may result in the improvement of the dynamic performance of the ribbon.

Also, the use of a laminate, which is tougher and more resistant to puncture than the present ribbon, may improve the life of the printer by reducing the number of wire breakages that are due to a wire being caught by the ribbon.
