    摘要: An uninterrupted bag making machine includes a conveyance unit, a conveyance unit driving means, a sealing unit having sealing assemblies, a sealing unit driving means, a perforating unit having a cutting device, a perforating unit, a perforating unit driving means, a breaking unit, and a control unit. With the conveyance unit, a film tube is conveyed to pass through the sealing unit, the perforating unit, and the breaking unit. Furthermore, with the control unit in cooperation with various driving means, the sealing assemblies can be moved in the direction of the film tube being moved, and the cutting device of the perforating unit is rotated in synchronous with the film tube being moved. As such, the film tube can be processed with sealing operations, perforating operations, and breaking operations at predetermined locations along the film tube without an interruption, so that the production rate and capacity can be increased.
