Title
(EN) VERTICAL DANCER WITH CONSTANT TORQUE
(FR) DANCEUR VERTICAL A MOMENT DE TORSION CONSTANT
Abstract
(EN)
A dancer assembly (10) for feeding a web of film (12) having ports extending therefrom to a former (16) for folding the web of film (12). The apparatus includes a dancer (20) having a roller (26) located between two tracks (51, 53) that allow the roller (26) to move vertically along the tracks (51, 53). The web of film (12) is fed around the roller (26) and vertically upwards toward the former (16). A quarter turn member (18) is further provided for changing the flow path of the film (12) from a substantially horizontal flow path to a substantially vertical flow path. And a member for moving horizontally, as a unit, the dancer (20) and quarter turn member (18) while maintaining a fixed spacial orientation of the dancer (20) and the quarter turn member (18) is provided. A method of feeding a web of film (12) to a former (16) is also provided.
(FR)
L'invention concerne un danseur (10) destiné à acheminer une bande de film (12), comportant des orifices, jusqu'à un cylindre enrouleur (16) destiné à plier ladite bande de film (12). L'appareil comprend un danseur (20) comportant un rouleau (26) situé entre deux pistes (51, 53) le long desquelles ledit rouleau (26) se déplace verticalement. La bande de film (12) passe autour dudit rouleau (26) et monte verticalement vers ledit cylindre enrouleur. On a également prévu un élément (18) à quart de tour destiné à changer la trajectoire du film (12) d'une trajectoire en gros horizontale à une trajectoire en gros verticale. On a également prévu un élément destiné à déplacer horizontalement et en une seule fois ledit danseur (20) et ledit élément (18) à quart de tour, tout en maintenant une orientation spatiale fixe du dit danseur (20) et dudit élément (18) à quart de tour. L'invention concerne également un procédé d'acheminement d'une bande de film (12) jusqu'à un cylindre enrouleur (16).
