Patent

CA 2273041

To roll paper or cardboard sheets (1) into reels (3) known winders have devices to turn the reel (3) and generate tension along the sheet (1) during rolling, as well as a contact roll (4, 19) that contacts the reel (3) under pressure. The contact roll (4, 19) together with the reel (3) forms a nip through which the sheet (1) is fed towards the reel (3). According to the invention, so as to carry at least part of the reel weight, at least one additional support reel (16, 20, 25) is placed underneath the reel (3). This support reel extends parallel to the axis of the contact roll (4, 19), is mounted in such a way that it can rotate freely or can be switched to free- wheel position, and on its outer surface has a deformable coating (18, 24) made of a cellular plastic material comprising numerous evenly distributed pores and having a compression modulus of less than 10 MPa.

Afin d'enrouler des bandes de papier ou de carton (1) pour former des rouleaux bobinés (3), on connaît les bobineuses qui comportent des éléments pour faire tourner le rouleau bobiné (3) et pour produire une tension dans la bande (1) lors du bobinage, ainsi qu'un cylindre de contact (4, 19) se trouvant sous pression contre le rouleau bobiné (3). Le cylindre de contact (4, 19) forme conjointement avec le rouleau bobiné (3) une ligne de contact entre rouleaux, dans lquelle la bande (1) du rouleau bobiné (3) est acheminée. Selon l'invention, pour recevoir une partie du poids du rouleau bobiné en dessous dudit rouleau bobiné (3), il est prévu au moins un rouleau de soutien (16, 20, 25) supplémentaire qui s'étend parallèlement à l'axe du cylindre de contact (4, 19), est monté de manière à tourner librement ou est commutable en roue libre et présente sur sa surface extérieure une couche (18, 24) apte à la déformation composée de matériau plastique alvéolaire comportant une pluralité de pores répartis de manière homogène et un module de compression ? de moins de 10 MPa.
