(EN) METHOD FOR PRODUCING A MATERIAL WEB, USE THEREOF AS A REINFORCING PLY FOR AN ELASTOMER ITEM, AND VEHICLE PNEUMATIC TYRES
(FR) PROCÉDÉ POUR LA FABRICATION D'UNE BANDE DE MATÉRIAU, SON UTILISATION COMME NAPPE DE RENFORCEMENT POUR UN OBJET ÉLASTOMÈRE ET PNEUMATIQUE POUR VÉHICULES
Abstract:
(DE) Verfahren zur Herstellung einer Materialbahn (1) aus in eine Kautschukmischung eingebetteten parallel zueinander verlaufenden Festigkeitsträgern (2) aus Stahl, mit folgenden Schritten: •d) Herstellung einer eine Oberplatte (3) bildenden Kautschukmischungsbahn und einer zweiten, eine Unterplatte (4) bildenden Kautschukmischungsbahn, • e) unter Spannung Hindurchführen einer Festigkeitsträgerbahn (2a) aus einer Vielzahl von parallel zueinander verlaufenden Festigkeitsträgern (2) durch den Walzenspalt eines Walzenkalanders (5), • f) Hindurchführen der Oberplatte (3) von der einen Seite und der Unterplatte (4) von der anderen Seite der Festigkeitsträgerbahn (2a) durch den Walzenspalt des Walzenkalanders (5) unter Zusammenfügen mit der Festigkeitsträgerbahn (2a). Die Festigkeitsträgerbahn (2a) wird vor oder bei ihrem Eintritt in den Walzenspalt mit im Wesentlichen quer zur Erstreckungsrichtung der Festigkeitsträgerbahn (2a) kontaktierenden Fäden (7) versehen, welche aus elektrisch nicht leitenden textilen Trägerfäden bestehen, die mit einer Beschichtung aus einem elektrisch leitenden Material versehen sind.
(EN) The invention relates to a method for producing a material web (1) from steel reinforcement elements (2) embedded in a rubber mixture and extending parallel to each other, said method comprising the following steps: d) producing a web of rubber mixture web forming an upper plate (3) and a second web of rubber mixture forming a lower plate (4); e) guiding a reinforcing web (2a) consisting of a plurality of parallel reinforcement elements (2) under tension through the roll gap of a roll calender (5); and f) guiding the upper plate (3) from one side and the lower plate (4) from the other side of the reinforcing web (2a) through the roll gap of the roll calender (5) with connection to the reinforcing web (2a). Before or during the insertion of the reinforcing web (2a) into the roll gap, the reinforcing web (2a) is provided with threads (7) that make contact substantially transversely to the direction of extension of the reinforcing web (2a) and consist of non-electroconductive textile carrier threads provided with a coating consisting of an electroconductive material.
(FR) L'invention concerne un procédé pour la fabrication d'une bande (1) de matériau constituée par des supports de renfort (2) en acier incorporés dans un mélange de caoutchouc, s'étendant parallèlement les uns aux autres, présentant les étapes suivantes, consistant à : - d) fabriquer une bande de mélange de caoutchouc formant une plaque supérieure (3) et fabriquer une deuxième bande de mélange de caoutchouc formant une plaque inférieure (4), - e) faire passer sous contrainte une bande (2a) de supports de renfort constituée par une multitude de supports de renfort (2) s'étendant parallèlement les uns aux autres à travers la fente de laminage d'une calandreuse (5) à cylindres, - f) faire passer la plaque supérieure (3) d'un côté et la plaque inférieure (4) de l'autre côté de la bande (2a) de supports de renfort à travers la fente de laminage de la calandreuse (5) à cylindres tout en les assemblant avec la bande (2a) de supports de renfort. La bande (2a) de supports de renfort est pourvue, avant ou lors de son entrée dans la fente de laminage, de fils (7) de contact, transversalement par rapport à la direction d'extension de la bande (2a) de supports de renfort, qui sont constitués par des fils support textiles électriquement non conducteurs, qui sont pourvus d'un revêtement en un matériau électriquement conducteur.
