の摩耗が著しく、コテの寿命が短くなつている。[Prior Art] In order to obtain a wide sheet by joining synthetic material sheets of fixed size, for example, as schematically shown in FIG. 3, the edges of the synthetic material sheets 11 and 12 are overlapped as joining surfaces. A pair of feed rollers 13 and 14 are provided to sandwich this joining surface, and a soldering iron 10 with a wedge-shaped tip is provided close to the feeding roller, and the joined portion of the synthetic material sheets to be welded is connected to the soldering iron 10.
It is inserted between the feed rollers from above and below, and before this insertion, the facing joint surfaces are heated and melted with a trowel 10, and the overlapped joint surfaces are pressed and welded by the feed roller. (Japanese Unexamined Patent Publication No. 63-137829) [Problem to be solved by the present invention] By the way, in order to melt the opposing surfaces of the synthetic material sheet just before inserting it between the feed rollers, the tip of the iron on the roller side must be It is formed into a wedge shape and is placed between the rollers so that its tip comes into contact with the sheet surface, which prevents melted pieces of the sheet from adhering to the surface of the tip of the iron and causing defective melting of the sheet surface. ing. Therefore, it is necessary to frequently remove the molten debris adhering to the iron, and the surface of the iron is polished by rubbing it with a wire brush or by inserting an abrasive cloth called an emery cloth between rollers. For this reason, the tip of the iron made of copper or an alloy is significantly worn, and the life of the iron is shortened.
本考案はこの点にかんがみ、コテ先端部の溶融
片の付着を少なくするものである。 In view of this point, the present invention aims to reduce the adhesion of molten debris to the tip of the soldering iron.

3 is formed into a wedge shape at the tip of the base material 1, and has a thermal sprayed layer 4 of smooth ceramics on the surface, and this thermal sprayed surface is filled with fluorine rubber. 5 is base material 1
A cover made of Cu or a Cu alloy is provided on the part other than the tip 3, and the outside thereof is covered with a heat insulating material 6 made of ceramics. 7 is a mounting piece, and 8 is a mounting hole.

要があるため、このような高温を要する溶着には
使用できなかつた。 The tip 3 of the base material 1 comes into contact with the synthetic material sheet and melts the joint surface of the sheet, so that melted pieces of the sheet adhere. For this reason, coating with silicone rubber or fluorocarbon rubber to improve smoothness and reduce the adhesion of molten pieces may be considered, but the heat resistance temperature of silicone rubber is 250℃, and the heat resistance temperature of fluorocarbon rubber is about 300℃. However, depending on the material of the synthetic material sheet to be welded, it is necessary to heat it up to about 500°C, so it could not be used for welding that requires such high temperatures.

高温にも十分な強度を保持できる。 Therefore, heat resistance and abrasion resistance can be maintained by the ceramics, and smoothness can be improved by the fluorine rubber filled in the porous sprayed layer. Note that the fluorine rubber, which has a low heat resistance temperature, is filled in the lattice-shaped pores of the ceramic sprayed surface, and its combined effect with the ceramic surface causes less wear and maintains sufficient strength even at high temperatures.

It improves the slippage with the synthetic material sheet, reduces the adhesion of molten debris, improves wear resistance, reduces wear caused by abrasive materials when removing molten debris, increases the service life of the iron, and reduces the need for replacement. This has the effect of eliminating the
