Abstract
A widthwise-compressing machine for applying a compression force through press tools to a material to reduce a width of the material while applying vibrations to said material to forcibly vibrate said material has a compression unit for producing a compression force forming a working force, and a vibration-applying unit for applying the vibration to said material. The vibration-applying unit is provided independently of the compression unit. In the widthwise-compressing machine, when the material is plastically worked, the material can be vibrated at an extremely high frequency to make it possible to resonate the material, thereby allowing the plastic-deformation thereof to be promoted.
