Title
(EN) WEB TENSION EQUALIZING ROLL AND TRACKING APPARATUS
(FR) ROULEAU REPARTITEUR DE TENSION DE BANDE ET APPAREIL DE SUIVI
Abstract
(EN)
A web tracking and repositioning apparatus having at least one pivoting conveyor roll (10) pivotable and rotatably supported at its center about a bearing assembly (218) through which extends a longitudinal fixed shaft (12). The bearing assembly connects to the conveyor roll (10) which is positioned at its weighted center about the bearing assembly. The ends of the conveyor roll extend outward toward fixed support members (152) and extend through and coaxially mount a pair of oppositely disposed guide blocks (310) which are pivotally mounted to the support members. A web of material conveyed over the conveyor roll is steered centrally following misalignment due to uneven tension in the conveyed web of material.
(FR)
L'invention concerne un appareil de suivi et de repositionnement de bande comportant au moins un rouleau de transport pivotant (10) pouvant pivoter et supporté rotatif par son centre grâce à un ensemble galet (218) à travers lequel s'étend un arbre fixe longitudinal (12). L'ensemble galet est relié au rouleau de transport (10) qui est situé de manière à ce que son centre de gravité se trouve au niveau de l'ensemble galet. Les extrémités du rouleau de transport débordent vers des éléments de support fixes (152) et passent, en montage coaxial, à travers une paire de blocs de guidage (310) opposés montés pivotants sur les éléments de support. Suite à un décentrage provoqué par des tensions inégales dans la bande de matière transportée sur le rouleau de transport, celle-ci est ramenée au centre.
