Abstract
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.
