摘要： PURPOSE:To prevent meandering and breakage of a strip during conveying by supporting the metal strip conveyed from a cooling roll to a spool with an air floater having little air blowing at center part. CONSTITUTION:The metal strip rapidly cooled and solidified on cooling single roll surface is detached from the roll with an air knife and caught with pinch roll on a conveying truck. The conveying truck is shifted to the spool to wind the metal strip. During conveying this, the metal strip is supported with the air floater, which distribution of the air blowing rate in the width direction of metal strip is less as coming to the center part. By this method, the conveying and coiling of strip are steadily executed. The air floater is desirable to be about 0.1 - 5 mm diameter of the air blowing hole and the pitch of the holes is preferably about 1.5 - 15 times the diameter of hole.

摘要： PURPOSE:To economically and accurately produce a metallic thin band by irradiating the metallic thin band running at high speed with parallel rays having a certain intensity from one side and converting the light which passes a hole to a current in a photomultiplier by a light receiving head on the other side to detect whether the hole exists or not. CONSTITUTION:The device consists of a light projecting system 10 consisting of a light source 11, a shutter 12, and a light shielding cover 13; and a light receiving system 20 consisting of a light receiving head 21, a photomultiplier 22, and an optical guide 24. When a metallic thin band 1 is inserted between the light source 11 and the light receiving head 21, the light of the light source 11 passes the optical guide 24 and is made incident on the photomultiplier 22 to detect a hole if the hole exists. Thus, the metallic thin band 1 while being carried at high speed without breaking can detect the hole.

摘要： PURPOSE:To pass a metal strip through a conveying guide under non-contacting condition and to prevent breakage by adjusting blowing quantity of air at the time of detaching a rapid solidified metal strip with a cooling roll by blowing air and introducing into a pinch roll after guiding in the conveying guide. CONSTITUTION:Molten alloy is injected on the cooling roll 1 from a pouring nozzle 9 and the rapid solidified amorphous strip 2 is detached with an air knife 3 and this strip 2 is guided into the conveying guide 4. Then, at the time of flying in the conveying guide 4, in order to prevent this strip from colliding to inner wall of the guide, by advancing/retreating an adjusting plate 11 in the conveying guide 4, gas stream width from an air knife 3 is adjusted to control so that the strip 2 glides in the guide under non-contacting condition. Successively, the strip is introduced to the pinch roll 5' constituted with a brush under opening condition and a solid roll 5, and after passing the strip between the rolls, the cast strip 2 is caught with pressing down of the pinch roll 5'. The cast strip 2 in the conveying guide 4 is passed through without breakage under non-contacting condition with upper and lower faces and side face of the inner wall of the conveying guide and further, the tension is given to the strip with the pinch roll 5' to obtain the strip.

摘要： PURPOSE:To prevent a metallic extremely thin plate from being cut and damaged by using jointly a pressure type floater with a tension adjusting device and a differential roller, controlling gas blowout pressure or a flow rate from the floater and adjusting temporarily its tension. CONSTITUTION:Air of prescribed atmospheric pressure and flow rate is fed to air floaters 10, 13 and 14 by an air feeding device 32, and while blowing it out of an exhaust nozzle 1a, it is fed from a quenching extremely thin band plate casting machine. Subsequently, a quenching extremely thin band plate W is wound round and run by non-contact, tension is measured by a tension detector 30 and a hydraulic device 33 is operated through a control panel 31, the air floater 10 is allowed to ascend and descend by a hydraulic cylinder 12, and by adjusting temporarily its running speed and while adjusting to prescribed tension, the band plate is taken-up like a coil by a take-up machine B. In such a way, a shock which is generated by tension shortage and a sudden increase of tension at the time of winding can be absorbed by a cushion effect caused by gas blowout pressure, and it can be prevented that the metallic extremely thin band plate is cut and damaged.

摘要： PURPOSE:To prevent the tail end cracking and deterioration of winding state by wrapping the coil with a metallic belt just before finishing the winding and winding while sliding the periphery of the coil with the metallic belt. CONSTITUTION:An upper arm 1 is rotated in a prescribed angle according to the diameter of the coil W1 by a hydraulic cylinder, 22, further, a top end arm 2 and lower part arm 3 are rotated until a steel belt 10 wound around the rotating axis 4 and idle roller 5 is contacted with the coil W1 through air cylinders 23, 24. Then, the coil W1 is wrapped with the belt 10 perfectly remaining a feeding clearance for the quick cooling thin belt W. At this time, winding shaft 6 is rotated in the direction shown by an arrow to draw out the belt 10 wound. When the coil 1 becomes into a prescribed diameter and the fed thin belt is cut by a cutter 32, the tail end of the coil slides between the belt 10 and the periphery of the coil W1 to be wound, the belt 10 and coil W1 slide until the rotation through the inertia is stopped. When the rotation is stopped, the belt 10 is returned, preventing treatment for loosening winding is performed.
