てなる包装機のフィルム折込装置。The film F is placed in the middle of a pair of side belts 10 and 10 that carry a large number of trays T, T, etc. arranged at equal intervals inside a continuous cylindrical film F, which are held between both sides and carried. In order to cut between each tray, a blade 14 is provided at the lower part and a groove-shaped guillotine 13 is provided at the same upper part, and two suction chambers 17 and 18 connected to a vacuum pump are provided before and after the blade 14, In a packaging machine in which the edges F□ and F2 of the film cut by the cutting mechanism are pulled into the suction ports 19 and 20 on the upper surface of the suction chamber, a film protection plate 27 is installed along the rear surface of the blade 14. The film protection plate 27 is installed such that its upper end protrudes from the upper end of the blade 14 and moves lower than the blade edge in conjunction with the lowering of the guillotine 13.
A roll 23 is provided on the rear side of the inlet 20 across the suction port 20,
A film folding device for a packaging machine, in which an air guide gap 25 is formed between the lower side of the roll and the mouth edge of the suction chamber 180 in the direction of the protection plate 27.
