<P>PROBLEM TO BE SOLVED: To provide a method and a device for appropriately preventing meandering of the tail end of a steel strip the end of which is paid off from a pay-off reel when a continuous steel strip processing line has an inlet equipment for paying off the steel strip (coil) alternately from a plurality of pay-off reels, in the continuous steel strip processing line provided with a continuous steel strip processing apparatus for continuously processing the steel strip while conveying the steel strip. <P>SOLUTION: Before the tail end of a preceding steel strip 5a is paid off from the pay-off reel 11, the preceding steel strip 5a is held with pinch rolls 16 between a cutting device and welding equipment and pinch rolls 32 on the outlet side of the welding equipment, the circumferential speed Vr of the pinch rolls 32 on the outlet side of the welding equipment is made slower than the conveying speed (circumferential speed of a bridle roll 33) Vs of the preceding steel strip 5a and the circumferential speed Vq of the pinch rolls 16 between the cutting device and the welding equipment is also made slower than the circumferential speed Vr of the pinch rolls 32 on the outlet side of the welding equipment (that is, Vs>Vr>Vq). <P>COPYRIGHT: (C)2013,JPO&INPIT |
