Title
(DE) VERFAHREN ZUR HERSTELLUNG VON LEICHTBAUBÄNDERN ODER LEICHTBAUBLECHEN
(EN) PROCESS FOR PRODUCING LIGHTWEIGHT CONSTRUCTION STRIPS OR LIGHTWEIGHT CONSTRUCTION SHEETS
(FR) PROCEDE POUR LA PRODUCTION DE FEUILLARDS LEGERS OU DE TOLES LEGERES
Abstract
(DE)
Verfahren zur Herstellung von coilfähigen Leichtbaubändern oder Leichtbaublechen aus mindestens einem ersten metallischen Gurt (1) und einem zweiten metallischen Gegengurt (5), wobei die Gurte (1, 5) als Blech oder Band ausgebildet sind. Auf einer Oberfläche (1a) des ersten Gurtes werden (1) regelmäßig sich wiederholende Erhebungen (2) durch einen Kalt- oder Warmwalzvorgang erzeugt und diese Erhebungen (2) mit dem Gegengurt (5) verschweißt.
(EN)
The invention relates to a process for producing coilable lightweight construction strips and lightweight construction sheets comprising at least a first metal flange (1) and a second metal mating flange (5), the flanges (1, 5) being in the form of a sheet or a strip. Regularly recurring bumps (2) are produced on one surface (1a) of the first flange (1) by cold or hot rolling, and said bumps (2) are welded to the mating flange (5).
(FR)
L'invention concerne un procédé pour la production de feuillards ou de tôles légers enroulables comprenant au moins une première semelle métallique (1) et une deuxième contre-semelle métallique (5), les semelles (1, 5) se présentant sous la forme de tôle ou de feuillard. Des bosses (2) à récurrence régulière sont réalisées sur une surface (a) de la première semelle (1) par laminage à chaud ou à froid, et ces bosses (2) sont soudées sur la contre-semelle (5).
