A bag feeder machine feeds plastic film a fixed distance that is set by the
operator. The figure shows a typical bag feeder that is part of the machine.
Bag feeder machines have two modes.
• Without mark: Forward feeds the film a set distance, for films of a flat colour
• With mark: Forward feeds the film to a printed mark on the film.
The program in this section shows the typical code for a bag feeder machine.
