Title
(DE) System zur Steuerung der Stichverteilung für Stopfmaschinen
(EN) Stitch distribution control system for tufting machines
(FR) Système de commande de distribution de maille pour machines à tufter
Abstract
(EN)
A stitch distribution control system for a tufting machine for controlling placement of yarns being fed to the needles of the tufting machine by yarn feed mechanisms to form a desired pattern. A backing material is fed through the tufting machine at an increased stitch rate as the needles are shifted according to calculated pattern steps. A series of loopers or hooks engage and pick loops of yarns from the needles. The yarn feed mechanisms further can be controlled so that selected loops of yarns can be back-robbed so as to be hidden from view in the finished patterned tufted article.

(FR)
L’invention concerne un système de commande de distribution de maille pour une machine à touffeter destiné à commander le placement des fils à amener aux aiguilles de la machine à touffeter par des mécanismes d’amenée de fil pour former un motif souhaité. Un matériau de support est amené à travers la machine à touffeter à une vitesse de maille accrue à mesure que les aiguilles sont déplacées en fonction des étapes calculées du motif. Une série de mailleuses ou crochets se mettent en prise avec des boucles de fils provenant des aiguilles et les lancent. Les mécanismes d’amenée de fil peuvent en outre être commandés de sorte que les boucles de fils sélectionnées puissent être repoussées à l’arrière de manière à être dissimulées une fois l’article touffeté et à motif terminé.
