Abstract
A bag making machine for producing plastic bags by processing plastic films by a processing device, wherein it is intended to accurately process plastic films, to protect the processing device from damage, and to save the required time while decreasing the processing rate as little as possible. A driving mechanism is connected to a processing device to drive the latter. Further, a control device is connected to the driving mechanism. After acceleration (.alpha.1) of the driving mechanism, the mechanism is once decelerated (.beta.1). At the start of the processing of plastic films, the processing device is driven at a low speed (V2). Further, as the processing proceeds, the driving mechanism is reaccelerated (.alpha.2) to drive the processing device at a high speed (V3).
