Patent

CA 2238651

An adhesive tape is provided which comprises a woven cloth, a polymer embedded into the cloth so as to cause the warp and weft fibers of the cloth to bond together at their overlapping points but not to completely encase the fibers, and a pressure sensitive adhesive coated onto at least a portion of the polymer, wherein the adhesive tape is hand tearable in the down-web and in the cross-web direction. A method of manufacturing such a tape is also provided.

L'invention porte sur une bande adhésive comportant une étoffe tissée, un polymère noyé dans cette étoffe, faisant s'assembler les fibres de chaîne et de trame de l'étoffe là où elles se chevauchent mais sans qu'elles ne s'encastrent complètement les unes dans les autres, ainsi qu'un adhésif autocollant déposé sur une partie au moins du polymère. La bande adhésive selon l'invention peut être déchirée à la main, longitudinalement et transversalement. L'invention porte également sur un procédé de fabrication de cette bande.
