Abstract

Selon l'invention, on réduit une zone de projection vue depuis une direction perpendiculaire à la direction de rotation d'un archet (11) pour un flyer, c'est-à-dire que l'on crée une forme de section trapézoïdale permettant de réduire la résistance à l'air sans limiter la productivité. Cet agencement permet d'économiser et de mieux utiliser l'énergie lors de la production d'un câblé en acier servant à renforcer une gomme.
