CA 2181716

A revolving mandrel holder (16) is capable of intermittent angular movement about an axis (X-X) inclined at an angle of 45° to the direction (f) of advance of the web material (N) being wound; said mandrel holder (16) carries two winding mandrels (12, 12A) on inclined axes relative to the axis (X-X) about which the mandrel holder (16) moves, so that at the end of each roll winding cycle an angular movement of the mandrel holder (16) brings a free mandrel into the winding position (12), and brings the mandrel with the roll (R) formed upon it into the position (12A) in which the roll can be taken off the mandrel that formed it. A plurality of lines (A, B, C) may be arranged side by side.

Porte-mandrin rotatif (16) apte à effectuer un déplacement angulaire intermittent autour d'un axe incliné (X-X) formant un angle de 45~ avec le sens (f) de l'avance d'un matériau en bande (N) à enrouler. Ce porte-mandrin (16) porte deux mandrins d'enroulement (12, 12A) dont les axes sont inclinés par rapport à l'axe (X-X) de rotation du porte-mandrin (16), de sorte que, à la fin de chaque cycle d'enroulement, un déplacement angulaire du porte-mandrin (16) place un mandrin libre dans la position d'enroulement (12), et place le mandrin sur lequel est formé le rouleau (R) dans une position (12A) dans laquelle on peut retirer le rouleau de ce mandrin. Plusieurs chaînes (A, B, C) peuvent être disposées parallèlement.
