ラツキが大きくなりがちであった。In the above-mentioned method, since the degree of heat applied is different between the outside, the inside, and the inside of the reel winding of the cable, there is a tendency for variations in the pitch dimension between the conductors of the parallel fusion portion to become large. It was

ないほどの不良品となる恐れがあった。Also, due to the waiting time until the user uses the reel-wound product after shipping, the pitch between conductors of the parallel fusion portion changes with the passage of time, and sometimes the variation becomes too large and the connectors are collectively packaged. There was a risk that it would be a defective product that could not be connected.

く。Then, the twist flat cable 3
The basics of twisted flat cables are made by repeating from 1 twisted portion to twisted portion-untwisted parallel portion-twisted portion, and the cores are heated by pressing the untwisted parallel portion with the mold 2 to heat. A parallel fusion-bonded portion 4 is formed so that the two insulators fuse together, and the insulation fusion machine 5 pulls the parallel fusion-bonded portion 4 to produce a predetermined twist flat cable.

付けるものである。In the process of forming the parallel fusion-bonded portion 4, the die 2 is subjected to rapid thermal deformation of the cable insulator to obtain a predetermined fusion-bonded structure. However, in order to remove the heat stress, a blower heater 6 is arranged between the mold 2 and the take-up machine 5, and the hot air 7 obtained thereby is directly applied to the entire width of the twist flat cable 3 in progress. It is something to spray.

Since it is possible to burn the cable, it is advisable to provide an exhaust heat outlet 6c so as to face the hot air outlet 6b so that the exhaust heat 8 is released during the stop. Hot air 7
To switch between the exhaust heat 8 and the exhaust heat 8, a means for changing the flow of the air may be added, such as a switching valve provided at the connecting portion between the hot air outlet 6b and the exhaust heat outlet 6c.
