摘要： PURPOSE:To obviate the generation of surface defects by chemical conversion treatment stains by dropping of a chemical conversion treating liquid to the front surface side of a band-shaped body from the ceiling of a chemical conversion treatment tank at the time of the chemical conversion treatment of the band-shaped body. CONSTITUTION:This device is provided with a shielding member 3 so as to extend in the transverse direction of the band-shaped body. The free end of this shielding member 3 is connected to a moving truck and the other end thereof is wound on a taking up device 5 and is adjusted to comply with the width of the band-shaped body. The chemical conversion treating liquid blown up from a spray nozzle 12 is shielded by this shielding member, by which the infiltration of the chemical conversion treating liquid to the front surface side of the band-shaped body is prevented. As a result, the generation of the surface defects by the chemical conversion treatment stains does not arise any more. The surface condition of the product is improved and the yield is improved as well.

摘要： PROBLEM TO BE SOLVED: To improve yield by preventing occurrence of such troubles as running failure, scratch accompanied therewith, bending, and material jamming when sheets such as a steel strip, especially a thin material and a very thin material are transported on a hot-run table. SOLUTION: Multiple water screens 2 are arranged between multiple carrying rollers 1. A sheet 6 during being carried in brought into contact with the water face or the water of the water screen 2 and guided. Since the sheet 6 is brought into contact with the water screen 2, the sheet 6 is not scratched and the yield is greatly improved. By carrying the sheet on the water screen, such troubles as sheet bending and material jamming are prevented and running failure after rolling is solved, whereby such troubles as line stopping and operation stopping are avoided.

摘要： PURPOSE:To prevent broken flaws based on buckling and to reduce adherence flaws by providing an auxiliary roller in contact with the external circumferential surface of a strip on the side of the progressive direction of the strip from a separation line in the width direction occurring at a place where the rewound strip is separated from a coil. CONSTITUTION:When the strip 11 is pulled out of the coil 10 and rewound on a tension bridle roll 110, a frame 40 stands up vertically and both rolls 20, 30 do not come into contact with the strip 11. Thereafter, the frame 40 is titled by a tilting cylinder 42 to the side of the coil 10 and the auxiliary roller 20 presses the external circumferential surface of the coil 10 from a separation line X' in the width direction of the coil 10 in the progressive direction of the strip 10 along this separation line X'. The winding restraint in the width direction of the strip 11 by the auxiliary roller 20 is enlarged and a separation position of the strip in the width direction is arranged forcedly. The frame 40 is titled by the tilting cylinder 42 to the coil side with the small change of the diameter of the coil 10 to touch the auxiliary roller 20 to the external circumferential surface of the coil 10. In this way, scratches based on the deviation of the coil, etc., are prevented.
