  • Patent number: 5984547
    Abstract: An object of the invention is to provide a seamless ink ribbon which makes it possible to markedly prolong the printing life, even with rather rough-faced printing paper such as paper made in China as well as a method of manufacturing the same.The seamless ink ribbon of the invention comprises a statically hot-pressed seamless woven fabric with multifilament yarn as warp and as weft. This ribbon is manufactured by subjecting a seamless woven fabric obtained by double weaving using multifilament yarn as warp and as weft to static hot pressing, without applying any shearing force, to thereby reduce the thickness of the fabric by 15 to 50% as compared with the thickness before pressing. The seamless fabric is fuse-cut to the ribbon width either before or after hot pressing.
