PURPOSE:To correct deflection and to obtain a product having good accuracy by rotating an eccentric shaft to generate a relative displacement in a vertical direction between an apron and supports. CONSTITUTION:When an eccentric shaft 9 is rotated, a sliding body 7 slides longitudinally according to a rotating angle and at the same time a relative displacement in a vertical direction arises between an apron 1 and front and rear supports 3, 5. The distortion is applied to the apron 1 and the same effect as the effect of an adjustable intermediate plate or shim is obtd. It is also possible to operate automatically the rotation of the shaft 9 by detecting the pressure in the lower part of the apron 1. |
