CA 2304623

A turret winder (10) for winding web material (40) on spindle-supported cores (32) has a turret (20) which is moveable into three indexing positions (A, B, C), one of which is a web transfer, cutting and winding station (B), and another of which is a winding completion station (C). Frames (12, 13) adjacent to the turret (20) support carriages (65, 70) which support a secondary lay-on roll (80). The carriages (65, 70) include a primary carriage (65) which is moveable vertically with respect to the turret (20) and a lay-on roll carriage (70) which is moveable horizontally with respect to the primary carriage (65). The lay-on roll carriage (70) has an arm (85) which is engaged by the turret (20) during movement of the spindle (29) between the above two positions so that arcuate movement of the spindle (29) is translated to movement of the lay- on roll carriage (70) in such a manner that the lay-on roll (80) accurately follows the movement as the building roll (55) moves to the winding completion station (C).

Enrouleur (10) à tourelle, destiné à enrouler un matériau en bande (40) sur des âmes (32) supportées par des broches, qui comporte une tourelle (20) pouvant se déplacer entre trois positions (A, B, C), dont l'une est un poste de transfert, de coupe et d'enroulement (B) de la bande, et une autre un poste de fin d'enroulement (C). Des châssis (12, 13) adjacents à la tourelle (20) supportent des chariots (65, 70) qui supportent un rouleau de préparation secondaire (80). Les deux chariots (65, 70) sont un chariot primaire (65), qui peut se déplacer verticalement par rapport à la tourelle (20), et un chariot de rouleau de préparation (70), qui peut se déplacer horizontalement par rapport au chariot primaire (65). Le chariot du rouleau de préparation (70) comporte un bras (85) qui peut entrer en contact avec la tourelle (20) durant le déplacement de la broche (29) entre les deux positions ci-dessus, de façon qu'un déplacement arqué de la broche (29) se traduise par un déplacement du chariot du rouleau de préparation (70) et que le rouleau de préparation secondaire (80) suive ce déplacement avec précision pendant que le rouleau d'accumulation (55) se déplace jusqu'au poste de fin d'enroulement (C).
