Claims

[Scope of utility model registration request]

a work clamp device that clamps a plate material between rotatable pads from both sides; a rotation drive device that indexes and rotates the pad; an angle detector that detects the rotation angle of the pad; A plate material rotating device comprising: a control device that lowers the rotational speed of the pad by the rotational drive device after the rotation starts and before the rotation stops than at an intermediate time.
