The Model A-22 is a versatile, fully automatic machine that features straight-line product flow. Centerfolded film is dispensed from a power unwind to the film inverting head which turns the film inside out, leaving an opening for product insertion. With each machine cycle, the infeed conveyor brings the product to the insertion arm and stops. The insertion arm advances the product into the film and on to the discharge conveyor, and then returns to receive another product. The sealing arm closes to seal the package. When the seal is completed, the arm opens and the discharge conveyor carries the package to the shrink tunnel. Meanwhile, the next product is being fed into the insertion and sealing stations of the machine automatically. The machine does not require a continuous flow of product for proper operation. Changeover takes only minutes.
