なる。 Traditionally, hole punching devices for cushioning sheets have been punch-type, in which a cylindrical punch is protruded from the outer circumferential surface of an embossing cylinder, or holes are provided separately from the embossing holes on the outer circumferential surface of an embossing mold. There are some known types that have a suction hole or a blow-out hole.
However, the punch-type punch does not heat the punch, which causes whiskers to form around the punched hole, resulting in poor cutting, and requires post-processing such as removing the whiskers, which is inconvenient. This often occurs especially when the film is softened at high temperatures. Additionally, the punch blade wears out rapidly, and there is a limit to machining speed. Furthermore, when a punch is not used, the embossing cylinder uses an iron roll, which leaves marks on the product. On the other hand, embossing molds with suction holes or blow-out holes may cause curls, wrinkles, or bulges at the perforated part of the product, or the holes may become misshapen. becomes uneven, and processing at low temperatures is not possible. Further, since it is necessary to provide a suction line and a blow-out line separately from those for embossing, the structure of the embossing mold becomes extremely complicated.

いうるようにしたものである。 This idea was developed to eliminate these drawbacks, and an embossing mold was installed next to the main roll that wrapped the film around it and fed it while heating.
On the metal surface of this embossing mold, a large number of recesses for embossing that can be sucked from the bottom are provided spaced apart from each other, and recesses for drilling are provided between the recesses for embossing. A protrusion roll of a metal needle heating type with needles separated from each other and protruding from the circumferential surface is provided so as to be able to come into contact with the surface of the embossing mold, and the circumferential surface of the protrusion roll other than the metal needles is made of silicone rubber, and the protrusion roll is made of silicone rubber. The surface movement speeds of the embossing die and protrusion roll are synchronized so that each metal needle on the roll enters the hole-drilling recess of the embossing die, and at the same time the cushioning sheet is manufactured. This makes it possible to reliably and easily punch holes in the adhesive sheet.

うにした。 The protruding roll 20 has a large number of metal needles 36 having good thermal conductivity protruding from its circumferential surface and spaced apart from each other. The metal needle 36 has a length of 0.5 to 5 mm and a diameter of 0.5 to 5 mm.
The diameter was 5 mm, and the tip was rounded. The cylindrical roll base 37 from which the metal needles 36 are protruded is made of metal with good thermal conductivity, and the outer periphery of the roll base 37 is made of a material that has good releasability, elasticity, heat resistance, and heat insulation, and has a slimy surface. The silicone rubber portion 38 was lined with silicone rubber having a property of adhesion to the film but not adhesion or adhesion. That is, the circumferential surface of the metal needle 36 other than the tip portion was made into a silicone rubber portion 38. In this way, if the surface of the protrusion roll 20 is made of the silicone rubber portion 38, it will have good surface adhesion, so the film will deform and shrink during heating, causing both ends of the film to move inward, causing the film to shrink. The film is dimensionally stable without narrowing or wrinkling, and is heated evenly. Also, after the film is heated and melted, it has good peelability when separated from the roll surface. . 39 is a heating device for heating the metal needle 36 of the projection roll 20. The heating device 39 may be provided inside the protrusion roll 20, as shown by the solid line in FIG. This heating device 39 for internal heating penetrates through the cylindrical rotation center shaft 40 of the protrusion roll 20 and is supported from the outside.
Of course, the heating device 39 may be of a radiant heating type such as an infrared heater provided on the outer periphery of the protruding roll 20, as shown by the two-dot chain line in FIG. A cartridge heater may be embedded from the side, and a slip-ring type energizing device may be connected to this rotating cartridge heater. The protrusion roll 20 has a circumferential speed synchronized with the circumferential speed of the cylindrical embossing die 8 so that the tips of all the metal needles 36 are sure to enter the recesses 31 for hole machining on the surface of the cylindrical embossing die 8. I made it rotate at a faster speed. Further, it was ensured that no holes were made in the five air chambers of the cushioning sheet 1. The diameter and depth of the recess 31 are made larger than the diameter and length of the metal needle 36 that enters the recess 31. The protrusion roll 20 was brought into contact with the surface of the cylindrical embossing mold 8.

ル２３に順次巻取る。 The film 9 delivered from the delivery roll 21 is wound around the main roll 10 and is successively fed while being heated from the outside, and is formed into the cap film 3 on the surface of the embossing cylindrical mold 8. The back film 4 sent out from the delivery roll 22 is laminated onto this cap film 3 to form the cushioning sheet 1. Thereafter, holes 7 are made by the action of the metal needles 36 of the projection roll 20, and the film is wound up. It is sequentially wound onto a roll 23.

けを確実容易に行うことができる。 In this case, a recess 31 for making holes is provided on the metal outer peripheral surface of the cylindrical embossing mold 8, and the tip of the heated metal needle 36 of the protrusion roll 20 is inserted into the recess 31, and the cylindrical embossing mold 8 and the protrusion are inserted into the recess 31. Since the rolls 20 are rotated synchronously, drilling can be reliably and easily performed with a weak force.

The diameter of the iron metal needle 36 is 0.5 to 5 mm, and the diameter of the recess 31 for drilling is 1 to 10 mm, and the depth is 0.5 to 5 mm.
5 mm, and the moving speed of the cushioning sheet 1, that is, the circumferential speed of the embossing cylindrical die 8 and the projection roll 20, is 1 to 30 m/min. In this case, the temperature at the tip of the iron metal needle 36 is 100 to 200°C. It is preferable to apply a release agent to the tip of the metal needle 36, but the application of the release agent is performed on the opposite side of the contact portion with the cylindrical embossing mold 8.
