Abstract

APPAREIL POUR L'AMENEE, PAR EXEMPLE A UNE TABLE DE DECOUPAGE, D'UNE FEUILLE DE MATIERE A MOULER, RECOUVERTE SUR CHAQUE FACE D'UNE PELLICULE DE VINYLE ET ENROULEE EN UNE GRANDE BOBINE. ON FAIT EN SORTE QUE LES ROULEAUX 24, 26, D'ENTRAINEMENT DE LADITE FEUILLE DETACHENT ET ENROULENT CHACUN L'UNE DES PELLICULES DE VINYLE FLANQUANT CETTE FEUILLE. CES ROULEAUX SONT MUS PAR UN MOTEUR PNEUMATIQUE ET SOLLICITES L'UN VERS L'AUTRE SOUS PRESSION CONTROLEE PAR UN VERIN PNEUMATIQUE 36. UNE VANNE PNEUMATIQUE A PEDALE 34 PROVOQUE LA ROTATION DES ROULEAUX. CET APPAREIL EPARGNE DES EFFORTS A L'OPERATEUR ET ENROULE PROPREMENT LES PELLICULES DE VINYLE RECUPEREES.APPARATUS FOR SUPPLYING, FOR EXAMPLE TO A CUTTING TABLE, A SHEET OF MATERIAL TO BE MOLDED, COVERED ON EACH SIDE WITH A VINYL FILM AND WOUND IN A LARGE COIL. THE ROLLERS 24, 26, FOR DRIVING THE SAID SHEET, EACH DETACH AND WIND UP ONE OF THE VINYL FILMS FLANKING THIS SHEET. THESE ROLLERS ARE MOVED BY AN AIR MOTOR AND STRAINED TO ONE ANOTHER UNDER PRESSURE CONTROLLED BY A PNEUMATIC CYLINDER 36. A PNEUMATIC PEDAL VALVE 34 CAUSES THE ROTATION OF THE ROLLERS. THIS APPLIANCE SAVES THE OPERATOR'S EFFORT AND WELLS CLEANLY RECOVERED VINYL FILMS.
