2. Description of the Related Art Conventionally, a side guide for centering a steel strip to be rolled and taken up by a winder before winding has been used because a short stroke cylinder guides both sides of the steel strip with a constant pressing force. If the tail of the steel strip has a widthwise extension called the bee spread, the side guides do not expand according to the widthwise extension, so the tail of the steel strip has a narrow side guide spacing. Will be forced to enter. For this reason, the steel strip may buckle and come off the side guide, and the centering may not be performed. When the steel strip (particularly the bee-spread portion) comes off the side guide, there is a problem that the edge portion of the steel strip comes into local contact with the side guide to generate a flaw (for example, a crack or the like). Since the tail of the steel strip is free, tension is not applied at the time of winding and it is not possible to tightly wind the coil, or the coil winding shape defect occurs and the coil touches other objects during coil handling, causing quality problems such as In addition, there is a problem that it adversely affects the line passing property at the next process and at the customer.

Next, the present invention will be described in detail with reference to the illustrated embodiment. 1 is a winding machine for winding the rolled steel strip through a pinch roll 2, 3 is a motor for driving the winding machine 1 for winding and driving, 4 is a rotation amount detector for detecting the rotation amount of the motor 3, 5. Is a control sequencer connected to the rotation amount detector 4, and the control sequencer 5 tracks the movement amount of the steel strip based on the rotation amount data detected by the rotation amount detector 4. It detects that the section has reached the position L before the side guide 6.

Further, the control sequencer 5 is provided with a pressure controller 8 to be described later which controls the pressing force of each of two short stroke cylinders 7 for centering and guiding side guides 6 arranged opposite to both sides on the winding machine entrance side. When the end of winding of the steel strip is approaching and the tail part with the bee spreads reaches L before the side guide 6, the rotation amount data of the rotation amount detector 4 is calculated to calculate the movement amount of the steel band. When the tracking is detected by the control sequencer 5, the control sequencer 5 issues a pressure reduction command to the pressure controller 8. This pressure reduction command causes the short stroke cylinder 8
The pressure of the pressing force is controlled. The amount of pressure reduction of the short stroke cylinder 8 by the pressure reduction control is set based on the hot strength in the width direction set by the sheet thickness, sheet width, yield stress, and the like of the steel strip being rolled.

After the pressing force of the short stroke cylinder 8 is reduced in accordance with the hot strength of the steel strip in this way, the tail of the steel strip is interposed between the side guides 6. At this time, the pressure of the short stroke cylinder 8 is controlled to a pressing force corresponding to the hot strength of the steel strip, so that the tail part of the steel strip does not buckle and the side guide 6 is moved by the width of the steel strip in the width direction. The tail portion of the steel strip is accurately guided by the side guide 6. In addition, since the side guide 6 guides the steel strip with the pressing force according to the hot strength, the winding shape of the coil does not deteriorate, and a constant tension is applied to the tail of the steel strip by the pressing force. As a result, the tail portion of the steel strip is also wound tightly. As a result, the number of flaws generated at the edge of the steel strip was reduced from 0.82 to 0.24 per coil. In addition, the occurrence rate of coil winding failure at the tail portion can be improved by 25%.
