いという重大な欠点があつた。``Prior art'' In the conventional method for manufacturing a heat-generating sheet disclosed in JP-A No. 57-87088, a heat-welding resin sheet such as polyvinyl chloride resin is placed on a mold, and the sheet is penetrated. Then, a large number of pins are protruded from below the mold onto the mold surface, and heating wires are locked and wired to the pins,
Next, another heat-welding resin sheet was placed above the pin and the heating wire, and an integral molding method was used in which the hot plate and the mold were used to press and heat.
Since there are many pin holes in the lower sheet, moisture enters through the pin holes, making it difficult to obtain a sheet generator with high quality in terms of insulation and waterproof properties. Furthermore, in the above conventional method, an air cylinder having a spring action on the spindle is used in order to make the pin protrude above the mold surface and move the pin down below the mold surface during or after heating under pressure. Since the pin is urged upward by the spring, when the heat-welding resin sheet is taken out upward, the pin attaches to the heat-welding resin sheet and rises, and the pin is pulled away from the heat-welding resin sheet. Not only is it difficult, but the molds, equipment, and devices are complex and heavy, and repair is difficult, leading to extreme price differences when producing a wide variety of products in small quantities. In addition, in the conventional Japanese Patent Publication No. 50-27219,
On the workbench, a guide protrusion is placed so as to penetrate through one base fabric and protrude from its surface, and after wiring the heating element while being guided by the guide protrusion, the guide protrusion is placed on top of the guide protrusion. A method for manufacturing an electric heating element such as an electric blanket or electric sheet is disclosed, in which a second base fabric is layered by penetrating the two base fabrics, and then, after these two base fabrics are joined, a guiding protrusion is taken out. However, according to the manufacturing method of the present invention, since the guide protrusion penetrates both of the two base fabrics, holes are formed in the two base fabrics, and moisture enters the interior through the holes, causing electrical insulation to deteriorate. A serious drawback was that only electric heating elements of inferior quality could be obtained in terms of durability and waterproofness.

る。"Means for Solving the Problem" That is, according to the present invention, positioning pins are installed in a mold having self-retaining force, and heating wires are wired to the positioning pins on the upper surface of the mold, and then the positioning pins are A first heat-welding resin sheet is placed on the heating wire, and the heating wire is bonded and transferred to the first heat-welding resin sheet by pressure heating between the mold and the hot plate, and at the same time, the positioning pin is a first step of pressing down and holding the heating wire in the mold, and turning over the first heat-sealing resin sheet on which the heating wire has been bonded and transferred, and placing a second heat-sealing resin sheet on top of the transferred first heat-sealing resin sheet. There is provided a method for manufacturing a planar heating element, characterized in that a second step is performed in which heat-sealable resin sheets are overlapped and heated under pressure between the mold and a hot plate.

Since the heating wire is stopped and held at , the heating wire bonded and transferred to the first heat-welding resin sheet can be easily pulled out from the positioning pin. Furthermore, since the positioning pin does not penetrate through either the first heat-welding resin sheet or the second heat-welding resin sheet, pin holes cannot be made in these first and second heat-welding resin sheets.

ト５を加圧加熱できる。"Embodiment" Below, a first embodiment of the present invention will be described. FIG. 1 shows a heating wire wiring process, in which a rubber plate 1c is sandwiched between two templates 1a and 1b. A self-retaining mold 1 is constructed, and positioning pins 2 are installed in holes drilled in advance in this mold 1, and heating wires 3 are wired to these positioning pins 2. Note that both ends of the heating wire 3 are fixed by wrapping them around the positioning pin 2 on the outlet side. Figure 2 shows the transfer process, and the silicone raw rubber sheet, which is about 0.4 mm thick and constitutes the first heat-welding resin sheet, has notches 4a on the positioning pins 2 and heating wires 3 in Figure 1. 4 is placed and heated under pressure between the mold 1 and a hot plate (not shown). Note that if the silicone raw rubber sheet 4 is reinforced with glass cloth, the mechanical strength will be increased. By this pressure heating, the heating wire 3 is bonded and transferred to the silicone raw rubber sheet 4.
At the same time, the positioning pin 2 is pressed below the mold 1 without making a hole in the silicone raw rubber sheet 4, and is held by the rubber plate 1c inside the mold 1 and stopped at the pressed position. When the silicone raw rubber sheet 4 is pulled upward, the heating wire 3 bonded and transferred to the raw rubber sheet 4 is easily pulled out from the positioning pin 2. FIG. 3 shows the sandwich process, in which the transferred sheet 4 obtained by the process shown in FIG. After sufficiently removing the internal air, the mold is heated under pressure between the mold 1 and the hot plate.
Obtain a primary silicone rubber heater. FIG. 4 shows the terminal connection process, in which the terminals 6 are connected to both ends of the heating wire 3 at the notch 4a,
A lead wire 7 such as a Teflon-coated wire or a silicon-coated wire is connected to the terminal 6. FIG. 5 shows the terminal protection step, in which a small piece of silicone raw rubber 8 is welded onto the notch 4a by heating and applying pressure. After the terminal protection process has been completed, the silicone rubber heater (sheet heating element) undergoes a final heating process and heat curing to obtain a high quality final product sheet heating element with no pin holes. It will be done. In addition, when manufacturing a large number of silicone rubber heaters of the same shape at the same time, a large number of silicone raw rubber sheets 5 are stacked with iron plates interposed between them, and a flexible rod such as a Teflon rod is interposed between the iron plates to efficiently manufacture them all at once. A large number of silicone raw rubber sheets 5 can be heated under pressure.
