つた。 In the case of artificial leather, cases and the like are also manufactured by the above-mentioned sewing operation, but when manufacturing at low cost and in large quantities, a manufacturing method using high frequency bonding is advantageous. However, if a bead is inserted during this high-frequency bonding, similar to sewing with a sewing machine, the thickness of the joint will increase by the thickness of the bead, which may weaken the bonding strength, reduce the bonding pressure, or increase the bonding strength. Had to increase power for.

The purpose is to provide a joining method, and for this purpose, out of two sheets of artificial leather to be joined, one sheet is folded back to form an overlapping part, the other sheet is overlaid on this overlapping part, and the two facing One of the electrodes is a thin-blade electrode, and this electrode presses the vicinity of the base of the folded bend of one sheet to bond the overlapping part and the other sheet at the same time, and simultaneously bond the folded bend. This is a high-frequency bonding method for artificial leather, which is characterized by forming it into a bead shape.

電極４に接するように置かれる。 In FIG. 1, among sheets 1 and 2 of artificial leather that can be bonded to each other by high frequency (dielectric heat welding), sheet 1 is stacked with its joint edges folded back so that the back surfaces 1b of the artificial leathers face each other, and the bent portion 1c An overlapping portion 1d is provided inside. On the other hand, the joining edge of the sheet 2 is overlapped with the overlapping portion 1d such that the leading end 2b of the sheet substantially coincides with the leading end of the sheet 1 on the folded side. In this case, both sheets are stacked so that the surfaces 1a and 2a face outward as shown in the figure. Next, the overlapped portion of the overlapping portion 1d of the sheet 1 and the joining edge of the sheet 2 is pressed between the high-frequency electrodes 3 and 4 as shown in FIG. 2, and a high-frequency voltage is applied between both electrodes to perform high-frequency bonding. dielectric heat welding). The high-frequency electrode 3 on the side of the sheet 1 is configured as a thin blade electrode with a tip 3a tapered to become thinner toward the tip, and the blade edge 3b of the electrode has a narrow width as shown in the figure. The plane or cross section is formed in an arc shape, and on the surface of the overlapping part approximately twice the thickness of the sheet from the base of the folded bent part 1c of the sheet, that is, the end face 1e of the bent part,
The overlapped portions of both sheets 1 and 2 are positioned so that the electrode edges are in contact with each other. The high-frequency electrode (counter electrode) 4 on the sheet 2 side is formed into a surface electrode with a wide contact surface with the sheet 2, and the back surface of the sheet 2 extends to the vicinity of the end surface 1e of the bent portion 1c as shown in the figure. placed so that it is in contact with

れる。 If the overlapping sheets 1 and 2 are placed between the two electrodes as described above, when they are compressed between the electrodes 3 and 4 as shown in Figure 2, the overlapping portion in contact with the thin-blade electrode 3 will be compressed. At the same time, the artificial leather deforms due to its elasticity, and the bent portion 1c in FIG.
It is formed on the bead 1c' as shown in FIG. In this state, a high frequency voltage is applied between both electrodes 3 and 4,
By dielectric heating, at the same time as the overlapping portion 1d of the sheet 1 is adhered, the sheet 2 is also adhered thereto. In this case, since both sheets are locally heated, the sheet that has been elastically deformed as shown in FIG. 2 is fixed almost in its shape, and the amount of return to its original state can be extremely small. That is, high frequency bonding (induction heating welding) and high frequency forming (induction heating forming) are performed simultaneously.

素となる。 Fig. 3 shows an example in which the joint portion obtained as described above is applied to the crown of a camera case. The bent part of the sheet 1 provided at the joint corner 8 with the artificial leather sheet 1, which forms the part 7 of the upper surface that intersects with the surface of 2, has the appearance as if a bead has been inserted. The beaded edge 1c' formed at the bent portion, together with the edging groove 1f formed by the thin blade electrode 3, becomes an element that provides an aesthetic appearance.

とは勿論である。 As is clear from the embodiment shown in FIG. 2 above, the diameter of the bead formed is approximately determined by the thickness of the sheet. Therefore, if it is desired to reduce the diameter of the bead, the joining edge can be shaved off so that the thickness of the sheet at the overlapping portion 1d including the bent portion 1c is reduced.
Conversely, if you want to increase the diameter of the bead, you can insert another ribbon sheet that can be bonded by high frequency (in this case, it does not need to be made of artificial leather) into the overlapped part to increase the thickness of the overlapped part. Bye. In addition, since the amount of protrusion of the bead 1c' is determined to some extent by the distance from the end surface 1e of the bent part to the tip 3a of the thin blade electrode, the distance can be determined appropriately and the gluing operation can be performed to obtain an aesthetic appearance depending on the surrounding situation. It is done. Furthermore, in addition to being applied to the corners of two substantially perpendicular surfaces as in this example, the joining method for forming a bead according to the present invention is also effective when applied to joining two parallel sheets. It is. Further, the overlapping portion 1d of one sheet may be bonded in advance at several points using an adhesive or high frequency to prevent the sheet from folding back. Furthermore, the artificial leather in the present invention is not limited to a refined natural leather, but may also be a textile-like material with a pattern on the surface, and the material may be impregnated or coated with a resin capable of high-frequency bonding to a fiber material, etc. Alternatively, the material may be attached in advance by coating or the like.
Furthermore, depending on the convenience of the bonding work, it is of course possible to process the electrodes and the sheet completely upside down from those shown in FIG. 1.

い目のような模様にすることもできる。 As described above, according to the present invention, the joining edge of one sheet is folded and polymerized without inserting a bead, and the thin blade electrode is used to connect the other sheet at an appropriate distance from the end surface of the folded and bent part. Since the bent portion is formed on the bead by pressing together with the sheet and performing high frequency bonding, the bead can be formed without increasing the electric power and adhesive pressure during high frequency bonding.
The joints also look beautiful due to the beaded edges, and have a great decorative effect. Furthermore, since the edge grooves are formed in addition to the bead edges by the thin blade electrode, a double frame edge pattern is created, which has the effect of further enhancing the aesthetic appearance. By adding an appropriate tooth profile to the tip of this thin-blade electrode, it is possible to create a pattern similar to sewing machine stitches.
