PURPOSE:To improve a cut work in quality ever so better, by coupling a load outputting part, outputting load to be secured from weight of a weight 2, and a load acting part to a work material with each of piston at both sides of a cylinder and transmitting the load to them via a transmitting fluid. CONSTITUTION:The vicinity of a left end part of a lever arm rod 51 of an automatic weighter 30 is set down to a fulcrum 0, and an intermediate part of the rod 51 is pivotally connected to an upper end of a driving rod 15, making it a working point P. Each weight 2 is made to act as a force point Q capable of shifting along the rod 51 free of forward and backward movements. These weights 2 are connected through a cord 54 of the length specified, and when it moves in an arrow C direction along the rod 51, load of a piston 5 follows movement of a self-propelled type weight 2a, and after moving a portion for length of the cord 54, this load increases according to movements of both weights 2a and 2b, whereby the load is transmitted to a piston 6 via oil 14 and given to an elastically rocked material 3 by a support device 29, thus a bound shock of the material 3 is absorbed. |
