2. Description of the Related Art For example, in Japanese Unexamined Patent Publication (Kokai) No. 5-212410, a stainless steel strip 1 is manufactured by using a series of continuous annealing and descaling equipment as shown in FIG. A configuration of a processing line for continuously processing is disclosed. The stainless steel strip 1 is delivered from the payoff reel 2, and the deflector roll 3 changes its traveling direction so as to follow the pass line of the entire processing line. In the pretreatment device 4, the leading zone and the trailing zone of the metal strip sequentially supplied from the pay-off reel 2 are sequentially welded and continuously fed into this processing line.
The looper device 5 supplies the stainless steel strip 1 stored in advance to the subsequent annealing device 6 or below even when the passage of the stainless steel strip 1 is stopped during welding in the pretreatment device 4. It is provided. Since oxide scale is formed on the surface of the stainless steel strip 1 annealed by the annealing device 6, it is chemically or mechanically removed by the descaling device 7. Since the passage time of the stainless steel strip 1 through which the annealing device 6 and the descaling device 7 are passed is strictly defined, a looper device 8 is also provided on the outlet side and the passage of the stainless steel strip 1 is performed on the downstream side. Even if the speed changes, the passing speed is adjusted to be constant in the annealing device 6 and the descaling device 7.

The stainless steel strip 1 whose strip-passing speed is adjusted by the looper device 8 has its length in the strip width direction made uniform by the side trimming device 9 and is introduced into the rolling mill of the first stage stand 11 via the bridle device 10. It The bridle device 10 is used to obtain a rolling tension required for a rolling mill having the first stage stand 11 or lower. Stainless steel strip 1
In some cases, only the temper rolling is performed by the first-stage stand 11 and the welded portion is separated by the shearing machine 12 and wound on the front tension reel 14 via the deflector roll 13. Further, not only the first stage stand 11 but also the downstream side stand 16 is passed through the centering device 15, and further cold-rolled, and then the rear surface tension reel 20 is passed through the pinch roll 17, the shear 18 and the deflector roll 19.
It may be rolled up. The pinch roll 17 is provided in order to give the stainless steel strip 1 a tension necessary for rolling sufficiently by the downstream stand 16. The processing line shown in FIG. 15 has an operation mode in which the front stage tension reel 14 is used to wind up the first-stage stand 11 and an operation mode in which the rear surface tension reel 20 is used to wind up the stainless steel strip 1 using the entire processing line. Used by switching. In order to perform this switching quickly, the front tension reel 14 is provided below the pass line of the stainless steel strip 1 as shown in FIG. 15, for example. The metal strip wound around the front tension reel 14 is a metal strip obtained by cutting the portion where the leading strip and the trailing strip are welded by the pretreatment device 4 again by the shearing machine 12. Winding a metal strip from one coil requires removing the coil and winding the next metal strip onto an empty reel.

A device as shown in FIG. 16 is used for initially winding the leading end of the metal strip on an empty reel. FIG. 16A shows the gripper device 22 provided inside the winding shaft 21 of the front tension reel 14. FIG.
(2) shows an outline of the belt wrapper device 23 that surrounds the outside of the winding shaft 21 and winds the tip of the stainless steel strip 1 around the winding shaft 21. In the gripper device 22, the stainless steel strip 1

In the belt trapper device 23, the tip of the stainless steel strip 1 is continuously fed and wound between the flexible rubber belt 24 and the winding shaft 21. In the gripper device 22, in order to ensure that the stainless steel strip is held by the gripper device 22, the threading is stopped once and continuous winding is started. After the start of winding, the belt wrapper device swings around the shaft 25 and retracts. In continuous rolling of plain steel or the like, a belt wrapper device 23 that does not stop the passing of the strip is often used.

[0005]

The front tension reel 14 as shown in FIG. 15 has one coil winding and
For quick winding of the next coil,
