Abstract

La présente invention concerne un procédé pour éviter l'enroulage en ruban lors de la fabrication de bobines réceptrices qui sont bobinées aux postes de travail de machines textiles fabriquant des bobines croisées à bobinage croisé au hasard, par modification de l'angle de croisement avec lequel le fil est enroulé sur la bobine réceptrice, les postes de travail présentant chacun un entraînement à moteur individuel, commandable de manière définie, pour la rotation de la bobine croisée et un entraînement à moteur individuel, commandable de manière définie, pour un guide-fil à va-et-vient. Conformément à l'invention, on détermine les diamètres (DSP k) de la bobine croisée (8), particulièrement importants pour l'enroulage en ruban, dépendant de la largeur (BSp) de la bobine croisée (8) ainsi que d'un angle de croisement (α) sélectionné lors du bobinage de la bobine croisée (8), juste avant que l'on obtienne un tel diamètre critique (DSP k), on modifie l'angle de croisement (α) à une valeur (α1) qui exclut la formation d'un enroulage en ruban dans cette plage de diamètres, et après le passage au-delà du diamètre critique (DSP k), on ramène l'angle de croisement (α1) à sa valeur initiale (α).
