Abstract
The present invention relates to a continuous shear deformation device. In order to occur shear deformation at the position at which a material is inserted into a molding path from a rotary guide apparatus for the purpose of solving the problem that the amount of shear deformation of a material is non-uniform and insufficient due to the gap between the curved portion of the molding path and the lower parts of the material, there is provided a continuous shear deformation device, characterized in that a curved portion is constructed by collaboration between the rotary guide apparatus and the molding path. In addition, there are provided additional constructions for effectively performing shear deformation by a small power by reducing the friction at the molding path excepting the curved portion. The present invention thusly constructed can be utilized for continuously and effectively mass-produce sheared materials.
