摘要： PURPOSE:To synchronously travel a snubber roll truck and a coil car to prevent the scratching of a strip coil by the traveling slippage between a snubber roll and the coil by setting the traveling resistance force of the snubber roll truck smaller than the frictional force between the snubber roll of the snubber roll truck and the coil. CONSTITUTION:A shifting air cylinder and a hydraulic cylinder are driven in the state where a frictional force is worked between a strip coil C and a snubber roll 1. At this time, since the traveling resistance force of the snubber roll truck 4 or the driving force of the shifting air cylinder 3, namely, the traveling driving force of the snubber roll truck 4 is smaller than the frictional force between the strip coil C and the snubber roll 1, the strip coil C is carried out by the driving force of a coil car 10, and the snubber roll truck 4 follows the coil car 10 moved through the strip coil C. Therefore, the traveling slippage between the snubber roll 1 and the strip coil C and the scratch of the strip coil C are never caused.

摘要： PURPOSE:To provide a simple device which permits simultaneous swiveling and lifting with a simple driving system by engaging an inside cylinder which is erected, is successively provided with a swiveling arm in the upper part and can be driven to move upward or downward and an inside cylinder which is fitted and fixed thereto by a spiral guide groove and engaging member. CONSTITUTION:The outside cylinder 12 is fixed to a hearth 27 as a fixing member and an electrically driven cylinder 13 is attached to the lower part. The spiral guide groove 15 is fixed to the surface of the inside cylinder 14 and the swiveling arm 16 is successively provided to the upper part. The cylinder 14 is connected via a bearing 17 to the cylinder 13. A swiveling guide roll 18 is attached as an engaging member to the upper step part A of the cylinder 12 and is made rollable in the groove 15. Four supporting rolls 19 are attached to the upper and middle step parts A, B of the cylinder 12 so as to contact with the cylinder 14. The cylinder 13 is risen in order to rise and swivel the arm 16. Then the cylinder 14 rises as well and the force in the swiveling direction is applied to the cylinder 4 by the engagement of the roll 18 with the groove 15, by which the cylinder 14 and the arm 16 are risen and swiveled. The descending and swiveling of the arm 16 are executed by the same principle.

摘要： PURPOSE:To prevent wrinkling of intermediate paper and rupturing of the paper even during such high-speed taking up as in a cold rolling stage at the time of inserting the intermediate paper among strips by moving a guide roll according to increasing of a coil diameter and adjusting the length of the intermediate paper between the guide roll and the coil. CONSTITUTION:Since the guide roll 1 is pressed to the intermediate paper P arriving at the coil C from a paper winder 7, the length to free the intermediate paper P up to the coil C is shortened to (a). The wrinkling and rupturing of the intermediate paper P are, therefore, prevented. Further, the length (a) at which the intermediate paper P is free, i.e., the length of the intermediate paper P between the guide roll 1 and the coil C, is adjusted by moving the guide roll 1 according to increasing of the diameter from the state at the time of starting taking-up of the coil C to the state at the time of ending of the taking-up, by which (a) is adequately maintained throughout the taking-up operation of the strip S.

摘要： PURPOSE:To enable highly efficient grinding by bringing the dresser edge neer to the surface of a grinding tool for a belt-like metallic body for detecting contact between both, finding circularity of the tool while using the contact point as a reference, and sending the dresser edge forward after a cutting quantity is determined so that prescribed circularity can be obtained. CONSTITUTION:A dresser 19 is moved forward to a grinding roller 1 by a guiding device 13, and the dresser edge 22 is contacted with the grinding roller 1, and contact is detected by a vibration sensor 23. A sound caused by the contact between both is detected by an acoustic sensor 24. Circularity S is found according to an equation I and an expression II by using a distance (r2) between the rotation center of the roller 1 and the dresser edge 22 at this time, a distance (r1) between the rotation center of the roller 1 and a surface of a belt-like metallic body, a grinding load F of the roller 1 and the ratio K of a radial directional disto tion quantity caused by elastic deformation to this grinding load, and a cutting quantity C is set from it and target circulariry E. The dresser edge 22 is sent forward according to this cutting quantity C, and grinding is carried out.
