A plastic bag making machine is disclosed, and includes a dancer assembly (203) that receives film (201) from which the bags are to be made. The film travels from the dancer assembly to a drum-in nip (205,206) and then to a sealing drum (208). After the sealing drum, the film travels to a drum-out nip (210,211). Then the film travels to a device-in nip (215,216), vertically through a processing device (218), and then to a device-out nip (219,220). A controller (221) 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 input is used to select one of a set of operating parameters and to enter at least one set of operating parameters, and a memory that stores the at least one set, and at least one output for controlling the machine. <IMAGE> |
