Abstract

L'invention concerne une courroie formée d'un matériau polymère thermoplastique ayant une section transversale d'épaisseur généralement uniforme et de configuration ondulée. L'invention concerne en outre un procédé et un appareil pour fabriquer une telle courroie. Cette courroie est fabriquée par un procédé dans lequel une bande 9 formée de matériau polymère thermoplastique non orienté est fournie avec une section transversale de configuration ondulée et d'épaisseur généralement uniforme par passage entre deux cylindres de gaufrage 49 et 51, avec au moins deux positions de cette bande comprimées de façon à orienter les molécules de polymère dans la direction transversale de la bande, après quoi la bande est allongée par passage entre deux cylindres d'étirage 53 et 55 pour orienter ses molécules de polymère principalement dans la direction longitudinale de la bande. On obtient ainsi une courroie 69. Courroie ayant une résistance à la traction élevée et une résistance améliorée au fendillement longitudinal et utilisable pour le serrage des emballages.
