Since the coil material is pressed downward by the dancer roll 180, the lube position of the coil material is detected and the speed of the uncoiler is controlled. In other words, the loop position of the coil material is the 20th loop position.
When in the state shown in Figure A, the loop amount of the coil material is insufficient, so the entire device is brought to an emergency stop. In the state where the loop material is in the mouth, the loop amount is insufficient, so leveler B is driven at high speed to adjust the loop amount to an appropriate level. . In the state C, the loop amount is approximately compatible with the speed of supplying the coil material to the press, and the leveler A may be driven at a low speed. In the second state, the loop amount is a little excessive, so the leveler B is stopped. In state E, the amount of loop is too large, so the leveler is put into emergency stop. In addition, in the condition E of the coil material, the distance between the coil material and the sledding table 171 is extremely small, so the drive motor of leveler B that is normally used will cause the coil material to coast, causing the coil material and the sledding table 171 to coast. 171, resulting in scratches or damage to the coil material. Therefore, the pinch roll 101 of the leveler B,
It is particularly necessary to quickly stop the coil 102 to prevent coasting of the coil material. For this purpose, the leveler drive motor is changed to a motor with a brake 121, and the disc brake 1 is

The functions of the threading table section J, sub-threading table section K, and side guide section L are as follows.

That is, when the coil material is attached to the uncoiler A by the coil force G, the sub-threading table portion K and the side guide table 205 interfere with the movement of the coil force G, so the sub-threading table main body 190 is moved by operating the cylinder 191. Rotate the side guide table 205 to the position shown in FIG.
Rotate it to the position shown by the dashed line in Figure 3. After the coil material is attached to the uncoiler A and the coil member G is moved to the outside, the side guide table 205 is rotated to the position shown by the solid line in FIG. 171 is raised by the cylinder 172, and at the same time, the sub-threading table main body 190 is rotated by the cylinder 191 to the position shown in FIG. The end of the coil material is moved on the subthreading table main body 190 and the side guide table 204, and the coil material is fed into the field roll F. Next, the threading table 171 is lowered, and the sub-threading table main body 1
90 to the position shown in FIG. 21 and drive the leveler B to form a loop in the coil material. It enters continuous operation. Since the present invention is configured as described above, the distance between the uncoiler A and the press machine E can be shortened, and the coil line can be installed in a narrow place.

Also, the snubber roll 64 of the snubber roll mechanism H presses the coil material D, and the coil oven mechanism 1 presses the coil material D.
Since the coil material D can be safely fed out by cutting the bundle, and the curl at the end of the coil material can be corrected by the end bending roller 74, the coil material can be smoothly fed into the leveler B.

1. Also, since the height of the rectangular cross-section coil material passage C can be adjusted by adjusting the distance between the lube table 141 and the upper cover 147 that constitute the coil material passage C, coil materials of different thicknesses can be smoothly handled. can be supplied to
1. Also, by moving the pair of receiving blades 166 of the width adjustment mechanism L toward each other and toward each other, coil materials of different widths can be fed smoothly by regulating their positions in the width direction so that their centers in the width direction always match. Coupled with the above-mentioned height adjustment, it is possible to always smoothly position and feed coil materials of different thicknesses and widths. Also,
Since the coil car G has a structure in which a table 5 is movable up and down on a moving main body 4, the coil material is placed on the table 5 and the main body 4 is moved to below the uncoiler A, and the table 5 is raised. Since the coil material can be pushed up to the uncoiler A, the coil material can be easily attached to the uncoiler A, and the coil material can be passed under the uncoiler A.

Further, since the threading table 171 is vertically movable, it can be adjusted to the height of the sub-threading table main body 190 of the sub-threading table portion K.
The unwinding side of the coil body can be smoothly fed out to the subthreading table body 190.

Further, the sub-threading table main body 190 of the sub-threading table portion K has a second structure that does not interfere with the coil force G.
Since the uncoiler can be rotated to the position shown in FIG.
