Patent

CA 2239678

A plastic bag making machine is disclosed, and includes a dancer assembly that receives film from which the bags are to be made. The film travels from the dancer assembly to a drum-in nip and then to a sealing drum. After the sealing drum, the film travels to a drum-out nip. Then the film travels to a device-in nip, vertically through a processing device, and then to a device-out nip. A controller is connected to and controls the drum-in nip, the drum-out nip, the device-in nip, the device out nip, the dancer assembly and the sealing drum (including the seal bars and/or the sealing blanket drives). The controller includes a memory in which at least one set of operating parameters used to control the machine is stored.

Machine à fabriquer des sacs en plastique comprenant un rouleau danseur qui reçoit la pellicule avec laquelle les sacs seront fabriqués. La pellicule est acheminée depuis le rouleau danseur jusqu'à une pince de tambour-entrée et un tambour de scellement. La pellicule est alors acheminée vers une pince de tambour-sortie pour se diriger ensuite vers une pince de dispositif-entrée, à la verticale, à travers un dispositif de traitement, et vers une pince de dispositif-sortie. Un contrôleur commande la pince de tambour-entrée, la pince de tambour-sortie, la pince de dispositif-entrée, la pince de dispositif-sortie, le rouleau danseur ainsi que le tambour de scellement (y compris les barres de scellement et/ou les commandes de blanchet de scellement) et est relié à ces derniers. Le contrôleur comprend une mémoire dans laquelle au moins un jeu de paramètres de fonctionnement utilisé pour commander la machine est enregistré.
