A continuous vertical form-fill-seal packaging machine is disclosed, along with a related method, utilizing a synchronized product clamp for staging/settling each product batch. The film feeding, carriage driving, sealing jaw movement, as well as the clamp operation, are computer controlled. In the continuous film/tube feed mode, the sealing jaws move in a modified sine wave motion with the film; the clamp for staging the product batches moving in a similar manner, but 180 DEG out-of-phase. Each product batch is released by the clamp adjacent to the sealing jaws so that the drop to the blousing plates and eventually into the bag being formed is minimized. The clamp is vibrated to further enhance the coalescing and settling function. |
