Abstract

PURPOSE:To obtain a seal such that air in a film is extracted perfectly upon heat shrinkage and a continuous material is closed perfectly upon finishing the shrinkage by a method wherein non-sealed parts for venting the air are formed on a sealing part with a predetermined interval. CONSTITUTION:A side sealing device consists or a pair of upper and lower driving rollers 1, 1' and one of the rollers is provided with notched recesses 7, in parallel to a roller shaft 6 or in diagonal direction with respect thereto, on the peripheral surface thereof with a predetermined interval. Indentations 2 parallel to the roller shaft are provided on circumferential surfaces between respective notched recesses. The indentations are intermittent when they are seen from the side thereof in case the notched recesses are parallel to the roller shaft but they are provided in continuity when they are seen from the side thereof in case the notched recesses are slanted with respect to the roller shaft. The circumferential surface of the opposite roller is flat. Two sheets of resin pressure bonding film 3, 4 are pinched between the upper and lower rollers and these rollers are driven. According to this method, two sheets of the resin film can be sealed while providing them with nonsealed parts for venting intermittently or diagonally on both sides of the films.

More specifically, when covering synthetic resin films with heat shrink processing to prevent contamination of long objects such as scaffolding boards that are transported into RI facilities such as nuclear power plants, as a pre-process of heat shrink processing, Although the four circumferences are sealed, this relates to the sealing devices on both sides.

。(Conventional wave tI) Conventionally, in nuclear power plants, etc., long objects were coated with synthetic resin to prevent contamination using polyethylene resin tubes.
A long object was inserted into this. Moreover, since this work was done manually, not only was the work efficiency low, but the effect of preventing contamination was also low, and there was a need for improvement in the coating work.

がある。Therefore, a method of covering with a resin film and heat-shrinking it has come to be used. To perform heat shrink processing,
As a pre-process, the four circumferences are sealed. In this case, there is a sealing device as shown in FIG. 3 as a device for sealing both sides in the longitudinal direction.

When the upper and lower rollers are driven, a continuous seal portion 5 is formed on the lower resin film.

Under good shrinkage conditions, this hole became smaller after shrinkage, but under some conditions it could become larger. High sealing performance is essential to prevent contamination, and even small holes cannot be left behind when deflated.

The present invention aims to provide a sealing device.

Notches parallel to the roller axis are provided on the circumferential surface between the notched recesses, and when the notched recesses are parallel to the roller axis, these notches are intermittent when viewed from the side, but when the notched recesses are parallel to the roller axis, On the other hand, in the case of an oblique direction, it is provided continuously when viewed from the side, and is not interrupted by the notch recess, and the peripheral surface of the mating opening is flat. By sandwiching two resin pressure films between the lower roller and driving the upper and lower rollers, it is possible to seal the two resin films while providing non-sealing areas for intermittent or diagonal air release on both sides of the film. did.

A notch 2 parallel to the roller shaft 6 is provided in a portion other than the cutout recess 7. The mating roller 1' has a flat circumferential surface. Then, the side edges of the two upper and lower resin films 3 and 4 that cover the covering such as the scaffolding board are sandwiched between the upper roller 1 and the lower roller 1', and when the upper and lower rollers are driven, the upper and lower resin films are separated by reference numeral 5. As shown, intermittent sealing is performed. That is, a non-sealed portion 5' remains which is not sealed.
