In order to solve this problem, the present invention utilizes the contrasting physical properties of a glass material and a metal fixing pin, and the glass material is rich in brittleness.
While it is easy to crush, metal fixing pins have high viscoelasticity and ductility, making effective use of the difference in physical properties that easily undergo plastic deformation, apply concentrated stress of pressure and compression to the object to be processed, and seat the glass material. Bending crushing and buckling deformation of a metal fixing pin cause thorough dissociation due to shear stress at the joint interface generated due to the difference in physical behavior.

By the way, when a roller is used as the pressure dissociation device, if the outer diameter of the processing object is too large with respect to the roller gap size, the processing object which does not pass through the roller gap is generated. Naturally, the applicable range of the input processing object tends to be narrow. In view of this, the invention according to claim 3 has a form in which two or more rolls are combined as shown in FIG.
