The Model FR-2 is a computer aided general purpose packaging machine. In conventional packaging machines, the sealing pressure is determined on the basis of the operator’s skill and experience. In this model, numerical packaging data for each product to be packaged are stored in the memory, and so the machine is adaptable for different product with ease and can be controlled accurately by the numerical control system. Change of the bag length, and adjustment of the position of the l - notch, perforation, and cutoff can be made merely touching the display of 9.5 inches with your finger. Fine adjustment can be made in a similar way even during operation of the machine. Anyone can operate the machine safely and correctly. To satisfy the user’s needs, an l - notch depth adjusting device has been incorporated into this machine.
