Abstract

L'invention concerne un procédé de production d'un câble multiconducteur, notamment d'un câble plat pour obtenir un câble multiconducteur hautement flexible et de grande qualité destiné à des tubes de câbles universels de manière avantageuse en termes de technique de production. Les conducteurs d'un faisceau de conducteurs sont serrés dans deux zones de faisceau distantes lorsque les sections de conducteurs situées dans les zones de faisceau sont orientées parallèlement et les sections de conducteurs du faisceau de conducteurs situées entre les points de serrage sont tendues par augmentation de la distance des points de serrage. Les sections de conducteurs tendues sont revêtues d'un plastique hautement élastique traité selon le procédé de coulée. A cet effet, les sections de conducteurs tendues traversent une zone de coulée d'un moule en deux parties.
