Abstract

The wear resistance of inking cloths is increased by warp and weft threads being positioned at an angle of 45o to the direction of movement of the type carrier. To date, the inking cloth has been moved with the warp and weft threads at an angle of 90 and 0Œ, respectively, relative to the direction of movement of the type carrier. When the type impacts the inking cloth, the warp threads, as the full tensile stress is absorbed by the weft threads, are taken along in the direction of movement of the type carrier, so that gradually a gap is formed in the inking cloth into which the type penetrates, tearing the warp threads. Subsequently, the weft threads are destroyed by the type, and a hole appears.

Inking Cloth With Increased Wear Resistance for High-Speed Printers

The wear resistance of inking cloths is increased by warp and weft threads being positioned at an angle of 45o to the direction of movement of the type carrier. To date, the inking cloth has been moved with the warp and weft threads at an angle of 90 and 0OE, respectively, relative to the direction of movement of the type carrier. When the type impacts the inking cloth, the warp threads, as the full tensile stress is absorbed by the weft threads, are taken along in the direction of movement of the type carrier, so that gradually a gap is formed in the inking cloth into which the type penetrates, tearing the warp threads. Subsequently, the weft threads are destroyed by the type, and a hole appears. By arranging warp and weft threads at an angle of 45OE to the direction of movement of the type carrier, the take-along force, caused by the type, is absorbed by warp and weft threads to the same extent, so that the fibers are no longer shifted against each other and a gap, in which a hole may appear, is prevented.
