げ”方式加工法がある。In the press brake or the like having the above-described structure, when the work W has the same plate thickness, the pressing force required for the bending operation of the upper table 1 for the bending work is determined by the bending of the work W. As the bending length increases, the pressing force increases in proportion to the length, and the deformation (bending) force of each upper / lower table 1/2 also increases. It has to be strong enough to withstand tonnage, and accordingly, the apparatus and related members have been increased in size and the cost has been forced to increase. As a method for solving the above problems, there is a so-called intermittent "feed bending" method as shown in the conceptual diagram of FIG.
