Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a method of manufacturing an electric blanket that is bonded and fixed using an adhesive or the like.

Conventionally, electric blankets were made by forming a loop in the raw cloth in advance and inserting a heating wire into the loop, but the work of inserting the heating wire was done manually, reducing productivity. It was low. Furthermore, the raw cloth through which the heating wire is inserted is made by joining two pieces of raw cloth and placing the inside of the raw cloth in the gap between the two pieces so that the gap is large enough to pass the heating wire through. The length of the heating wire is not constant, and when electric blankets are mass-produced, the length of the heating wire is not uniform, so when comparing each electric blanket, there is a difference in the length of the heating wire, and the quality is poor. It was inconsistent.

The present invention improves the above points and makes it possible to consistently manufacture electric blankets.The drawings are examples showing the method for manufacturing electric blankets of the present invention, and FIG. , a process diagram showing a method for manufacturing an electric blanket. FIG. 2 is a plan sectional view showing the joining of raw cloth. 3 and 4 are plan sectional views showing the arrangement of heating wires. Figure 5 shows the completion of fixing the heating wire.
FIG. From each figure, the electric blanket uses raw cloth such as raised cloth or non-woven cloth, and two sheets of raw cloth (Ll, (
Layer 2) on top of each other, and first add the raw cloth (1).

The - side of (2) is joined to form a first joined part (6), and inside the raw cloth (]) of this joined part (6), (2), the joined part (6 ) along which the heating wire (5) is arranged. The heating wire (5) is fixed between the first connecting portions (6) by a second connecting portion (7), and the heating wire is connected along the second connecting portion (7). (5) is provided. Since the second joint (force) is located within the raw cloth (+7, (2)), the heating wire (5) is folded back and follows the second joint (7). Next, a third connecting part (8) is provided to fix this heating wire (5), and the heating wire (5) is folded back along this third connecting part (8). Then, repeat the arrangement of the fourth connection part (9) and the heating wire (5), and the fifth connection part (10) in order, so that the final shape becomes a loop shape. are arranged in the raw cloth (IJ, (2)) and the parts except the heating wire (5) are connected. In other words, the heating wire (5) is arranged and fixed, and the raw cloth (+1,
Since the connection in (2) can be performed in the same process (3), it is possible to perform continuous production, and the connection and heating wire (5) can be performed either before or after the installation process (3). Then, cutting step (4) of raw cloth flJ (2) is added. In addition, when raw cloth (1) and (2) are made of nonwoven fabric,
Punching with a needle punch or joining with adhesive is possible.

Furthermore, if the raw fabric (]) or (2) is a raised fabric, it can be tied by sewing. Furthermore, according to the method of manufacturing an electric blanket of the present invention, a sensor wire can be disposed at the same time as the heating wire (5), and the heating wire (5) and the sensor wire are connected to the first connecting portion (6). ), second connecting part (7),
Continuously with the third connecting part (8) and the fourth connecting part (9),
Since they can be placed along each joint, the length of the heating wire (5) and the sensor wire in the raw cloth (1) and (2+) can always be uniform, so the length of the finished cloth can always be uniform. Each electric blanket has a uniform heating wire (5) and a uniform sensor wire, making it suitable for mass production.

Furthermore, the heating wire (5) and the sensor wire may be formed coaxially.
