Title: Method for controlling width of sheet in hot rolling
Inventor: ISHII ATSUSHI
IPC: B21B37/22
Filed: 1994-05-25
Abstract: PURPOSE:To improve dimensional accuracy and yield by enabling the estimation of the variation of width and calculation of tension control taking the variation of sheet crown ratio as a parameter and executing the setting change of a screw down contoller and sheet crown/shape controller by tension change. CONSTITUTION:The region in the vicinity of roll bite (RB) is analized using of a sheet rolling analyzing system. Width variation on the inlet side of RB and in RB is increased and decreased by the various change in rolling conditions such as a draft, length of arc of contact, tension between stands and variation of crown ratio and its rate is changed by the thickness and deflection resistance of a rolled stock. By taking the variation of sheet crown ratio as the parameter, the highly accurate estimation of the variation of the width and the calculation of proper tension control are enabled and the setting of the screw down controller and sheet crown/shape controller of each stand are changed so as to compensate effect on thickness and the amount of sheet crown by tension change. In this way, comprehensive dimensional accuracy of width, thickness, the amount of sheet crown, sheet shape, etc., is ensured.

Title: Reduction gear in delivery station of machine that processesplate-form article
Inventor: JIYAN KUROODO REBOO
IPC: B65H5/36
Filed: 1995-05-10
Abstract: PURPOSE: To make the additional manual substantially unnecessary by providing a horizontal ramp which works on an upper end of an inclined arm directed upward and toward the downstream, and a downstream portion of the ramp is inclined upward. CONSTITUTION: When a cam 60 presses a lever 62 clockwise, the lever 62 lowers a pulling handle 64, i.e., a bar 66, and at the same time, rotates angularly adjustable levers 73, 74 counterclockwise. As a result, this rotation lowers a lower part tightening tool 76, and downwardly translates a ramp 40 in the perpendicular direction. An inclined arm 24 and a cross bar 11 are rotated counterclockwise by thus lowering the ramp 40 to lower a brush 10 to a sheet deceleration position. The ramp 40 is thus lowered against the effect of a spring 78. On the other hand, when the upper position of the cam 60 is moved farther away from the scanning lever 62, the tension spring 78 elevates the ramp 40, and elevates the brush 10 at the same time.
