Title
(EN) REWINDER LOG CONTROL
(FR) DISPOSITIF DE CONTROLE DE L'ENROULEMENT D'UN ROULEAU
Abstract
(EN)
A rewinder log control for decelerating soft paper logs (54) including a pair of log control fingers (152, 154) having opposed distal concave portions defining a cylindrical cavity for contacting a spinning log after a rewinding operation. The log control fingers also have proximal convex portions for nesting in adjacent diameter control roll grooves to permit positioning the log control fingers out of the way for core insertion and log rewinding. A cam plate (164) having a cam track (174) is mounted on the rewinder machine frame and a cam follower (176) coupled to the log control fingers moves along the track as the machine moves through its rewinding cycle to move the fingers between a first or clearance position and a second or deceleration position.
(FR)
Un dispositif pour contrôler la décélération de rouleaux (54) de papier doux comprend deux doigts de contrôle (152, 154) ayant des portions distales concaves opposées délimitant une cavité cylindrique et venant en contact avec le rouleau en rotation après l'opération d'enroulement. Les doigts de contrôle du rouleau ont également des portions proximales convexes venant se loger dans des rainures de rouleaux adjacents servant au contrôle du diamètre, pour écarter les doigts de contrôle afin de pouvoir insérer le noyau et procéder à l'enroulement. Une plaque-came (164) ayant un canal (174) est montée sur le cadre de la machine à enrouler et une contre-came (176) couplée aux doigts de contrôle suit le canal à mesure que la machine à enrouler effectue le cycle d'enroulement, pour amener les doigts de leur première position dégagée vers une seconde position de décélération.
