ABSTRACT:
A device for moving a curved plate bent in a substantially arcuate-shape along a curved path, in which a lift arm pivotably supported on a pivot is operatively connected at one end thereof to a lift arm bracket having a bent end portion in such a relationship that the extension line of the bent end portion of the lift arm bracket makes an acute angle with the axis of the pivot supporting the lift arm. Due to the fact that the lift arm is connected to the bent end portion of the lift arm bracket by means of a guide pin which is guided in a predetermined direction along a slot provided in the bent end portion of the lift arm bracket and the extension line of the bent end portion of the lift arm bracket makes the acute angle, namely an angle less than 90.degree. with the axis of the pivot supporting the lift arm, the end of the lift arm connected to the lift arm bracket can also make arcuate movement not only in the direction perpendicularly intersecting the thickness of the curved plate but also in the direction of the thickness of the plate, and therefore, the curved plate moved in a predetermined direction with the movement of the lift arm can be guided along the curved path of the guide runs without imparting any stress to the device.
