CA 2205795

A roll-forming apparatus is disclosed which forms individual rolls of material from continuous or interleaved webs. The apparatus includes a conveyor which directs each web of material to an associated intermittently indexed turret assembly. The turret assembly includes a plurality of rotatable spindles thereon for respective formation of rolls of material from the individual webs. The apparatus includes various drive arrangements so that the surface speed of each spindle is matched to the speed of the apparatus conveyor during transfer of each web to a respective one of the spindles. Separate drive systems are preferably provided for effecting driven rotation of each spindle during winding of the rolls, and for effecting intermittent, indexed movement of the turret assembly. An additional drive mechanism desirably effects reverse rotation of each spindle to facilitate removal of the completed roll therefrom.

Machine pour former des rouleaux individuels de bandes de matériau continu ou interfolié. La machine comporte un convoyeur qui dirige chaque bande de matériau vers une tourelle à mouvement indexé. La tourelle comporte une pluralité de broches pour la formation de rouleaux à partir des bandes individuelles de matériau. La machine permet divers réglages de l'entraînement, de sorte que la vitesse de rotation de chacune des broches est adaptée à la vitesse de transfert de chaque bande de matériau. De préférence, la rotation de chacune des broches durant la formation du rouleau et le mouvement indexé de la tourelle sont assurés par des systèmes d'entraînement distincts. Un mécanisme d'entraînement supplémentaire pourra assurer la rotation inverse des broches pour faciliter l'enlèvement des rouleaux de matériau.
