Abstract

Many of the presently available wide multi-strike inked fabric ribbons employ a costly set of aluminum bars as reversing mechanisms. This article describes an improved reversing mechanism for such ribbons. A common reversing mechanism currently manufactured consists of crimping the multistrike inked fabric ribbon between two aluminum bars. The bars, which extend over the widths of the fabric, are located near each end of the ribbon. When an end is reached, as the fabric is being used, the over-extended aluminum bar trips the gears and the mechanism causes the rolls to reverse direction. As an improvement over aluminum bars, heat and pressure application (essentially, ironing) of a heat- sensitive acrylic adhesive-backed aluminum tape gives the same desired results.

Aluminum Foil Tape As a Reversing Mechanism for Inked Fabric Ribbons

Many of the presently available wide multi-strike inked fabric ribbons employ a costly set of aluminum bars as reversing mechanisms. This article describes an improved reversing mechanism for such ribbons. A common reversing mechanism currently manufactured consists of crimping the multistrike inked fabric ribbon between two aluminum bars. The bars, which extend over the widths of the fabric, are located near each end of the ribbon. When an end is reached, as the fabric is being used, the over-extended aluminum bar trips the gears and the mechanism causes the rolls to reverse direction. As an improvement over aluminum bars, heat and pressure application (essentially, ironing) of a heat- sensitive acrylic adhesive-backed aluminum tape gives the same desired results. A metal sensor is employed rather than a mechanical stop mechanism. One strip of aluminum tape is placed at each end (on one fabric side only) for a total of two per ribbon. The tapes stand up well to the rigors of printer testing and accelerated aging.
