Abstract
A fixed cutter is provided on a top surface of an adsorption type carrying belt that carries a film. A cylindrical cutter holder having a rotary cutter is provided in the vicinity of the fixed cutter. The fixed cutter has nearly a triangular cross section, and includes an inclined surface that guides the film on the top surface of the belt to a blade edge and a flank relief having nearly a V-shaped cross section. A blade edge of the rotary cutter is disposed at an offset position. The film is cut by a relative operation of the blade edges while rotating the rotary cutter with respect to the fixed cutter. Both of the cutters are installed in a cutter unit, and are fixed to a frame part of a packaging machine while performing positional adjustment.
