Abstract
An endless woven garniture tape or belt for cigarette making machines comprising a combination of natural, chemically modified, and synthetic fibers in a unique blend and arrangement which possesses properties that result in superior wear life performance without sacrificing other performance criteria. The warp is made from combed sak cotton fiber threads, with a multiplicity of such threads mercerized and plied together to form each warp thread. The filling threads are made up of a multifilament synthetic core wrapped with cotton fiber with a multiplicity of such wrapped threads plied together to form each filling thread. Endless belts made according to this invention have a wear life approximating three times the normal wear life of conventional belts used on cigarette making machines.
Claims6
An improved garniture belt for cigarette making machines having optimum properties of wear and abrasion resistance, flexibility, tensile strength, and dimensional stability, comprising a narrow endless woven fabric belt of predetermined length made from specially structured warp and filling threads, said warp threads consisting of a plurality of sak cotton fiber threads plied together and mercerized to form each warp thread, said filling threads consisting of a plurality of synthetic core threads plied together to form each filling thread, each said core thread comprising a multifilament synthetic core overwrapped with a sheath of cotton fibers, and said woven belt impregnated with a sizing solution and cured to stabilize the belt to the desired dimensions.
An improved garniture belt for cigarette making machines having optimum properties of wear and abrasion resistance, flexibility, tensile strength, and dimensional stability, comprising a narrow endless woven fabric belt of predetermined length made from specially structured warp and filling threads, the weave type of said belt selected from the group consisting of plain, modified plain, and twill, each said warp thread consisting of from 3 to 4 sak cotton fiber threads plied together and mercerized, each said filling thread consisting of from 3 to 6 synthetic core threads plied together, each said core thread comprising a multifilament synthetic core overwrapped with a sheath of cotton fibers, said core comprising from 34 to 72 filaments selected from the group consisting of polyester and polyamide filaments, and said woven belt impregnated with a polyamide sizing solution and heat cured to stabilize the belt to the desired dimensions.
