Title: Rolling device
Inventor: MIYASHITA TOSHIO
IPC: B21D1/02
Filed: 1983-11-10
Abstract: PURPOSE:To prevent occurrence of distortion of shape of a rolled material and to improve yield of production of the rolled material by detecting amount and position of generation of sag due to deviation of tail end of the rolled material when taking up the rolled material came out from a finishing mill, and controlling movement in axial direction and gap of a pinch roll accordingly. CONSTITUTION:The rolled material 2 that comes out from a group of finishing mills 1 is pulled out through pinch rollers 4, 5 and wound on a winder 18. The moment the rolled material 2 passed the group of finishing mills 1, if the tail end of the rolled material 2 is deviated sideways and sag is generated in the direction of width, the size and position of sag are detected by shape detectors 10, 11 provided in downstream side of the second pinch rollers 8, 9 at respective place. The amount of movement in axial direction and gap of the second pinch rollers 8, 9 are controlled by the detected value, and the sag is removed before the rolled material 2 passes the pinch rollers 4, 5 or during passing. Generation of drawing flaws due to shape distortion during winding of the rolled material is prevented, and lowering of yield of product of the rolled material is prevented.

Filed: 1985-09-26
Abstract: PURPOSE:To protect a data recording area on a magnetic disc by making move a magnetic head to a head landing area by the second movable carriage after the completion of the operation of a device. CONSTITUTION:Immediately after the completion of the operation of the device, conduction to an electromagnet 10 is cut off, and the second movable carriage is released by the force of a fixing claw spring 9. The released second movable carriage is moved in the direction of the head landing area by the force of a spring 5. At such a time, a head movable carriage 4 is pushed and moved with the second movable carriage and a magnetic head 3 is moved to a head landing area 2. At the start-up time of the device, the head movable carriage 4 moves the magnetic head 3 to the most outside peripheral cylinder by the gear operation of the device main body. At such a time, by the appropriate setting of the force of the spring 5, the second movable carriage 7 is also moved simultaneously with it. Since the electromagnet 10 is energized at the start-up time of the device, a fixed claw is attracted, fixing the second movable carriage at the outermost periphery.
