On the outer surface of each side wall 66a, 66b of the cutter portion 60 are cylinders 83a, 83b, 84a.

In order to easily understand the operation of this device, the forward and backward states of the piston rods of the cylinders 64 and 122 are shown in each of FIGS. 78 to 7I. In this case, the stroke amount of the cylinder 64 corresponds to the longitudinal dimension of the intermediate strip region of the covered wires 600a, 600b, and the stroke depth of the cylinder 122 corresponds to the cutting depth of the sheathing portion, which will be described later.

First, before the start of operation, the piston rod of the cylinder 64 is in the advanced position, and the other cylinders 83a, 83b
, 84a, 84b, and 122 are in the retracted position. Also, upstream and downstream clamps 90.1
00's grip on the covered wires 600a and 600b has been released. In this state, the two fl electric wires 600a, 6
00b is fed by a predetermined amount along the wire feeding direction P by the length measuring device 0-raD (and the draw roller 120). next,
As shown in step 821, the covered wires 600a and 600b are held by the upstream and downstream clamps 90, 100 so as to be stretched, respectively. As a result, the tips of the cutting cutters 808 and 80b are respectively disposed corresponding to positions near the downstream end of the intermediate strip area of each of the electrically coated electrodes 1600a and 600b.

Next, as shown in FIG. 7A, cylinder 84a.

84b is advanced and the cutting cutter 80a is operated.

80b, cut the covering part until it reaches the core wire (No. 7A)
In the figure, only one side of the coated wires 600a and 600b is shown, and only one side of each of the two cutters 70a and 80a for cutting and tearing is shown.

is sandwiched between the cutting cutters 70a and 70b, and the entire circumference of the coating at the downstream end position of the planned intermediate strip area is cut until it reaches the core wire (step 52).
3). Next, from this state, as shown in Figure 7F,
The piston rod of the cylinder 122 is moved forward, and the piston rods of the cylinders 83a and 83b are moved backward in synchronization therewith. As a result, the cutting cutters 70a and 70b are opened while moving in the direction of the arrow Q, and the covering portion at the downstream end of the area where the intermediate strip is planned moves upstream while being locked by the cutting cutters 70a and 70b. Pushed in. As a result, the covering portion at the downstream end of the planned intermediate strip region is compressed and separated from the covering portion downstream from it, and is peeled off from the core wire.

On the other hand, due to the advancing operation of the piston rod of the cylinder 122, the tips of the cutting cutters 70a and 70b move to a position corresponding to the upstream end position of the area where the intermediate strip is planned, and then as shown in FIG. 7G. , cylinder 8
Each of the piston rods 3a and 83b is moved forward, and the cutting cutters 70a and 70b cut the entire circumference of the covering portion at the upstream end of the area where the intermediate strip is planned (step 524). In this cutting state, as shown in FIG. 7H, the piston rod of the cylinder 122 is moved backward, and in synchronization therewith, the piston rods of the cylinders 83a and 83b are moved backward. As a result, the cutting cutters 708 and 7ob are opened while moving in the direction of arrow P, and the covering portion at the upstream end of the area where the intermediate strip is planned is moved downstream while being locked by the cutting cutters 70a and 70b. Pushed in. As a result, similarly to the above, the covering portion at the upstream end of the intermediate strip area is compressed so as to separate from the covering portion on the upstream side, and is peeled off from the core wire. In this case, as shown in FIG. 7J, the covering portions of the intermediate strip region are connected at both the upstream and downstream end positions and are integrated surrounding the core wire 131, so that the covering portion of the intermediate strip region part is core wire 1
There's no way he'll drop out of 31.

Next, in step 825, are both clamps 90 and 100 covered?
The grip on the i electric wires 600a and 600b is released.

At the same time, the next intermediate strip area is cut into the cutting cutter 8.
It is fed to the position corresponding to 08.80b. Then, the process returns to step 821, and the above-described operations are repeated to continuously process the intermediate strip area.
