Therefore, the heating jig 3 is moved from the center of the heat-shrinkable tube 2 toward one end, and the tube 2 is sequentially shrunk from the center toward the ends. Next, the motor 9 is reversed and the heating jig 3 is returned to the center of the heat-shrinkable duplex 2. At this time, the heater power is turned off.) Then, the heater power is turned on and the same heating process is performed in the opposite direction to the previous one. Do this.
以上で熱収縮デユープの加熱収縮が終了し、この後加熱
冶具を上記チューブより取り外し全作業が終る。This completes the heating contraction of the heat-shrinkable dupe, and then the heating jig is removed from the tube to complete the entire work.
