PROBLEM TO BE SOLVED: To prevent deformation of a soft packing object so that a load is not applied to a folding-in margin of an end part of the packing object by a constitution of a film folding-in mechanism.SOLUTION: A film folding-in mechanism 5 is provided so that an endless reed screen conveyor 7 is arranged in a lower part, and a suction chamber 8 for sucking a folding-in margin 4 of a packing object 1 is arranged inside the reed screen conveyor 7, and a side conveyor 6 for carrying the packing object 1 covered with a film is arranged in an upper part of the reed screen conveyor 7, and the speed ratio of a carrying speed Vw of the packing object 1 by the side conveyor 9 to a moving speed Vt of a reed screen opening part 10 of the reed screen conveyor 7, is set in response to a dimension Dt[mm] of the folding-in margin.SELECTED DRAWING: Figure 3 |
