Before the fusion cutting device 10 cuts the double-layer film (b), electricity is conducted to the heater 20 to generate heat in the heater 20, and the cutting knife 12 is heated by the heat The cut surfaces of the upper and lower two-layer films (b) are fused to each other by the heat of the cutter (12) while the cutter (10) cuts the two-layer film (b).

That is, the double-layer film (b) is cut in the longitudinal direction of the double-layer film (b) by the fusion cutting device (10) The upper and lower films are fusion-bonded to each other by the heat of the heater 20 conducted to the upper and lower substrates 12 and 12 to be fusion-cut.

The fusion-spliced double-layer film (c) has a fusion-spliced portion (d) in which the cut surface is welded by the heat of the cutting knife (12) do.

Generally, a method of fusing a two-ply film is a method of fusing two films The width of the fused portion is enlarged because the cut portions of the film are vertically welded at predetermined intervals in a predetermined interval. The present invention is also applicable to a case where the cut knife 12 cuts the double-layer film (b) The fused portion d is formed to have a small width so that it can not be determined whether or not the fused portion d has a configuration.

The sealing bar is elevated and lowered by an actuator such as a pneumatic cylinder, a hydraulic cylinder, and an electric motor. The heater heats the sealing bar to ultimately heat the film material, that is, the double wrap film material, Cools the fused portion which is thermally fused by the sealing bar.

When the double-layered film is positioned between the sealing bar and the cooling bar, the sealing bar heated by the operation of the heater is lowered by the operation of the actuator, so that the double-layered film is thermally fused with the heat- The welded portion is formed with a constant width.

That is, in the general double-layer film fusion, only the film that comes into contact with the upper film, that is, the sealing bar, is melted by the heat of the heater, and the melted portion is fused to the lower film which is not melted, The width of the portion becomes large.

However, the end of the fusing and cutting device 10 of the present invention, that is, the end of the cutting knife 12 cuts the two-ply film b in a sharp state like a blade, (b) is brought into contact with the side surface of the cutting knife (12), at which time the respective cutting surfaces of the two-ply film (b) are melted by the heater row on the side of the cutting knife (12) Are welded to each other to form a very small fused width of the fused portion (d), and the fused films are mutually fused to each other, thereby ensuring fusion, that is, fusion bonding is more reliable than the fusion width.

The bottom surface 14 of the body 11 of the fusion cutting device 10 is formed as an arc in the longitudinal direction and an arc cutting knife 12 extending integrally in the longitudinal direction is formed on the bottom surface of the arc.

The body 11 of the fusion cutting device 10 is configured such that the upper surface 17 is formed in a plane and both side surfaces are planar and a heater hole 13 is formed in the body 11 in the longitudinal direction of the body 11 A heater (20) generating heat by electricity is formed inside the heater hole (13).

The bottom surface 14 of the body 11 of the fusion cutting device 10 is constituted by a plane or an arc surface in the transverse direction or a surface in which the inclined surface and the plane are mixed and the bottom surface 14 is formed by mixing the inclined surface and the plane The inclined surfaces are inclined at both sides of the body 11 so that the distance between the both inclined surfaces becomes narrower from the lower end toward the center of the body 11, and the plane is composed of a plane connecting the ends of the inclined ends.
