ãã Generally, it is difficult to obtain thick plastic sheets of approximately 1 mm or more by directly molding a wide sheet from a molding machine, and the width of a thick sheet directly molded from a molding machine is approximately 200 cm in the largest class.
Because of this, the manufacture of thick plastic sheets with wide widths was accomplished by laminating and connecting multiple sheets together.

ããšã¯ã§ããªãã€ãã However, as a method of bonding and connecting thick plastic sheets, for example, the method of heat-sealing the thick sheets is usually used, but this heat-sealing has poor thermal conductivity of the thick sheets. It is extremely difficult, and in reality, it is only carried out in factories equipped with special equipment (there is also a width limit for factory-produced sheets, which can only be about 10 meters wide at most).
However, it has not been possible to easily connect long thick sheets at construction sites for irrigation rivers, ponds, etc.

ãã ããæ¬çºæãå®æããã The inventors of the present invention have conducted intensive research on a method for connecting thick plastic sheets (thickness: 1 to 4 mm) easily even at construction sites. The tape is used to temporarily bond the heat-sealing tape to the edge of the thick plastic sheet by a specific temporary bonding device at a low temperature of about 50-110â, and then at a high temperature of about 120-250â. The present invention was completed by discovering a method for connecting thick plastic sheets by heating the heat-sealing sheets and thermally bonding them together.

ã®ã§ããã As described above, the method of the present invention allows the heat seal tape to meander by simply moving the temporary connection device, which can be easily moved linearly without meandering, along the overlapped portion of thick plastic sheets. By using this temporary adhesion method, the subsequent main adhesion work can be done without causing wrinkles or misalignment of the heat seal tape. This can be done effectively without creating bubbles or peeling between the heat-sealing tape and the thick sheet.Moreover, since the thick sheet is not exposed to excessive heat history, the thick sheet itself can be sealed. will not be thermally deformed (curled), wrinkled, or melted and torn.
It hardly impairs the durability of thick sheets.

It consists of a straight (cylindrical) roll made of metal. Further, the elastic roll 34 is
It connects to the metal roll 32 to perform secondary temporary bonding of the heat seal tape 2, is provided at the rear of the bottom of the temporary connection device 3, and is made of foamed urethane. The roll 32 provided at the front is a metal straight roll, and the roll 3 provided at the rear is a metal straight roll.
The reason why 4 is an elastic roll is because the front roll 32
is required to be heat resistant to the heating of the preheater 33, and the temporary connection device 3 can be moved without meandering to connect the front roll 3 as shown in FIG.
2, the heat seal tape 2 is temporarily attached to the upper part 11a of the step in the overlapping portion 11, and the rear roll 34 is used to temporarily adhere the heat seal tape 2 to the remaining lower part 11a' of the step. By doing so, the heat seal tape 2 is reliably and easily temporarily bonded to correspond to the step difference in the overlapping portion 11 without meandering.

This makes it possible to preheat uniformly and reliably across its width. Incidentally, the preheating of the heat seal tape 2 may be performed before the heat seal tape 2 is pressed by the metal roll 32. Therefore, the preheating by the preheater 33 is performed so that the heat seal tape 2 is heated as shown in the figure. For example, instead of pre-heating the adhesive layer of the heat-sealing tape 2, the overlapping portion 1 may be heated immediately before the temporary connection device 3 is suspended on the temporary connection device 32.
This may be carried out by preheating the surface of the heat seal tape 1 or by preheating both the surfaces of the adhesive layer of the heat seal tape 2 and the overlapping portion 11.

The ends of the thick plastic sheets 1, 1' are heated to a high temperature of ~200°C and pressed with a pressing roll 6 such as an elastic roll or sponge roll, preferably a stepped pressing roll 6 as shown in the figure. The edges and the heat seal tape 2 are bonded (fused) by heating as shown in FIG. In this case, in order to prevent the flame of the gas burner 5 from reaching both sides of the temporarily bonded heat seal tape 2, an appropriate flameproof wall, flameproof screen, etc. should be installed, or a flameproof sheet or board should be installed. It is appropriate to arrange these on the surfaces of the thick sheets 1, 1' on both sides of the overlapped portion 11 of the heat seal tape 2. Further, the above-mentioned preheating and the above-mentioned high-temperature heating are not only carried out using the flame of the above-mentioned gas burner, but also using other known heating means, such as electric heaters, infrared heaters, other hot wire heaters, heating rolls, This can be done by using an electric iron, spraying a heating medium, etc. Other pressing means may also be used for the pressing roll 6. Furthermore, in the method of the present invention, for example, after completing the temporary bonding work of the heat seal tape 2, the subsequent heat bonding work at a high temperature may be performed, or both processes may be performed almost simultaneously with a slight time difference. It can also be carried out in close succession.

ãã§ããã In addition, when manufacturing the heat seal tape 2, for example, a polyolefin film or sheet is formed by extrusion molding from the above-mentioned polyolefin resin composition, and an adhesive is coated on the film or sheet by a lamination method in which an adhesive is extruded. Form an adhesive layer, and then crosslink the laminate (sheet) from the adhesive layer side with an electron beam or the like to produce a tape consisting of a partially crosslinked adhesive layer and a crosslinked polyolefin layer. In addition, heat seal tapes are made by separately manufacturing a cross-linked polyolefin film or sheet and an adhesive sheet, and then pasting them together to form a laminate (sheet), and then attaching the adhesive layer side to the adhesive sheet. It can also be produced by crosslinking with electron beam irradiation or the like.

The thickness of the crosslinked polyolefin layer is about 0.1 to 4.0 mm, particularly about 0.1 to 3.0 mm,
The thickness ratio of the adhesive layer and the crosslinked polyolefin layer is about 1:10 to 3:1, and the total thickness of the heat seal tape 2 is about 0.5 to 5 mm.
In particular, a thickness of about 1 to 4 mm is preferable because it has flexibility that is convenient for handling, or because it has sufficient mechanical strength after connection. In addition, the width of the heat seal tape 2 (the length in the direction perpendicular to the longitudinal direction of the tape) is approximately 5 to 50 cm, especially 10 to 50 cm.
