As shown in FIGS. 10 and 11, the work S is placed on the molding surface of the lower mold 71. After arranging and setting the electric wire W above this, the covering crimper 73 and the core wire crimper 74 attached to the ram 72 are lowered to cover the covering barrel piece c and the core wire barrel piece d.
At this time, the electric wire W is pushed into the U-shaped portion to be processed b, and in particular, a part of the core wire n does not protrude outside the core wire barrel D, so that a so-called core wire spill does not occur. An electric wire retainer 75 is provided between the crimper 73 and the core wire crimper 74. The wire retainer 75 is made of a block-shaped plate material, and a tension spring 78 is suspended between the upper portion of the wire retainer 75 and the spring receiving pins 76 and 77 provided on the ram 72, and is biased and attached downward. This electric wire retainer 75 has a lower surface provided with a side surface 79 for moving the electric wire W to the center.
Thus, the electric wire W is moved to the center and then housed in the work S, and subsequently, both crimpers 73 and 74 crimp the processed portion b. As a result, both barrels B,
When C is molded, the electric wire W is housed in the processed portion b and then crimped, so that the core wire is not spilled.
