Patent

CA 2208164

The invention concerns a method in winding, wherein a number of separate rolls (13a, 13b, 13c, 13d, 13e, 13f) are formed side by side around separate roll spools (15a, 15b, 15c, 15d, 15e, 15f) placed one after the other while supported by support members (11, 12). In order to reduce the friction coefficient of the roll spools (15a, 15b, 15c, 15d, 15e, 15f), before, or at the same time as, the roll spools are placed in the winding position, the ends of the roll spools are treated with an agent that reduces the friction coefficient, or pieces of a material that has a low friction coefficient are placed at the ends of the roll spools, and/or the axial thrust force between the roll spools is lowered by passing a pressurized medium through the spool locks.

Procédé de bobinage dans lequel un certain nombre de bobines séparées (13a, 13b, 13c, 13d, 13e, 13f) sont formées côte-à-côte autour d'axes d'enroulement séparés (15a, 15b, 15c, 15d, 15e, 15f) placés l'un derrière l'autre et supportés par des éléments de support (11, 12). Afin de réduire le coefficient de frottement des axes d'enroulement (15a, 15b, 15c, 15d, 15e, 15f), avant de placer les axes d'enroulement en position de bobinage, ou en effectuant cette opération, on traite leurs extrémités à l'aide d'un agent réduisant le coefficient de frottement, ou des pièces d'un matériau présentant un coefficient de frottement peu élevé sont placées aux extrémités des axes d'enroulement, et/ou la force de poussée axiale entre les axes d'enroulement est réduite par le passage d'un fluide pressurisé par les fixations des axes.
