Deep-drawing packaging machine
A deep-drawing packaging machine includes a sealing device that clamps and seals a top film and a bottom film by an upper mold and a lower mold, clamping tabs that clamp both-side edges of at least one of the top film and the bottom film, and a carrying device that carries at least one of the top film and the bottom film clamped by the clamping tabs. The clamping tabs are configured such that a gap is generated between the clamping tabs and the top film and the bottom film, positioned in a range clamped by the upper mold and the lower mold, when the upper mold and the lower mold of the sealing device are closed.
1. A deep-drawing packaging machine comprising:
a sealing device that clamps and seals a top film and a bottom film by an upper mold and a lower mold;
clamping tabs that clamp two side edges of at least one of the top film and the bottom film;
a carrying device that carries the at least one of the top film and the bottom film clamped by the clamping tabs; and
a cutter that cuts the sealed top film and bottom film at a predetermined position;
wherein:
a gap is generated between (i) the top film and the bottom film and (ii) each one of the clamping tabs that is positioned along a range of the top film and the bottom film that is being clamped by the upper mold and the lower mold, when the upper mold and the lower mold of the sealing device are closed; and
a gap is also generated between (i) the top film and the bottom film and (ii) each one of the clamping tabs that is positioned along a range of the top film and the bottom film that is in contact with the cutter.
