A plate thickness pressing method for pressing a substantially rectangular material, comprising the steps of: pressing a substantially rectangular material in a widthwise direction to perform width adjustment; andsubsequently applying plate thickness pressing in a plate thickness direction to said substantially rectangular material by using a die having a main processing surface consisting of at least an inclined portion on an input side and a parallel portion following said inclined portion with respect to said substantially rectangular material, wherein a non-steady width change amount &Dgr;W and a non-steady length &Dgr;L generated in at least one of a front end and a rear end of said substantially rectangular material by said plate thickness pressing are predicted by using the following expressions and said front end of said substantially rectangular material is preformed based on this prediction:&Dgr; WH=f1(W,&egr;, Ldt), &Dgr;WT=F2(W,&egr;, Ldt)&Dgr; LH=g1(W, h, Ldt), &Dgr;LT=g2(W, H, Ldt)where &Dgr;WH is a predicted non-steady width change amount generated at said front end of said rectangular material in a moving direction by plate thickness pressing; &Dgr;WT, a predicted non-steady width change amount generated at said rear end of said rectangular material in said moving direction by plate thickness pressing; &Dgr;LH, a predicted non-steady length generated at said front end of said rectangular material in said moving direction by plate thickness pressing; &Dgr;LT, a predicted non-steady length generated at said rear end of said rectangular material in said moving direction by plate thickness pressing; H, a plate thickness of said substantially rectangular material on a press input side; h, a plate thickness of said substantially rectangular material on a press output side; &egr;(=log(H/h)), a plate thickness strain; Ldt, a contact length of said material and said press die in a longitudinal direction; and W, a plate width of said substantially rectangular material. 7. A plate thickness pressing method, comprising the steps of: preforming a substantially rectangular material by pressing in a widthwise direction to effect width adjustment to provide a distribution to a plate width of a steady portion of said substantially rectangular material in a width adjustment direction of plate thickness pressing wherein said width adjustment is carried out by a vertical rolling mill capable of changing an opening during processing; andsubsequently applying plate thickness pressing in a plate thickness direction to said substantially rectangular material by using
