PURPOSE:To improve the precision of cutting and to increase the number of times of reciprocation of the blade with less stroke even though the weight of multiblade assembly is made greater by making the length of blade less and the width of that greater to provide a greater stiffness to the blade. CONSTITUTION:Blades 1 and spacers 2 are alternately piled, the lower end of the multiblade assembly 3 held in the state of raising the blade 1 is supported by the parallel plate springs 4, 4' through the fixtures 5, 5', the lower ends of plate springs 4, 4' are attached to the base 7 with the fixtures 6, 6'. Also a plunger 8 with high permeability is fixed to one side of the assembly 3, it is attracted by the solenoid 9 supported by the stand 10 through the holder 11. A spring 14 is put in the cylinder 13 of the upper end of the work cutting bed 12 which is movable up and down, the supporter 16 of a work 15 is inserted in the cylinder 13 to put itself on the spring 14. |
