If the problem arises of providing the finished corrugations with very short protruding wire ends, that is to say shortening the otherwise resulting longer wire ends, the pliers are provided with cutting edges 70 at the ends. These cutting edges 70 cause the wire to be notched and torn off when the last piece of the wire end is pulled out. The length of the wire ends to be cut is determined by the time at which the rotary movement begins when sledding and by the pressure during the closing movement or the length of the closing path.

Abstract

Procédé pour relier deux barres qui se croisent (61, 62), en particulier des fers d'armature dans une construction en béton armé, et installation pour réaliser ce procédé. Le procédé recourt à un outil en forme de tenailles (4) qui est tout d'abord fermé autour des barres à relier; un fil de fer (59) est ensuite avancé, cisaillé et serré, après quoi les tenailles sont rouvertes et les deux barres sont repoussées de la zone des tenailles grâce à un poussoir (36). Finalement, les tenailles se referment pour exécuter un mouvement de rotation afin de torsader les extrémités du fil autour des fers d'armature à relier. L'installation pour réaliser ledit procédé présente, en tant qu'éléments constitutifs, des canaux d'amenée de fil de fer (45, 46) complètement fermés et placés dans les deux bras de tenailles (5, 6) de l'outil en forme de tenailles et ces bras de tenailles (5, 6) permettent de commander le dispositif de serrage (18) ainsi que le dispositif de cisaillage (14, 48).
