Abstract: A punch apparatus for punching and laminating simultaneously a plural number of thin sheets is disclosed. This punch apparatus includes a punch provided on an upper portion of the punch apparatus, a die provided on a lower portion of the punch apparatus and used for punching a material to be processed, a stripper for guiding the punch during punching operation, a device for laminating punched materials using the punch as a laminating axis, a device for adjusting a relative position between the punch and the stripper when the upper and the lower portions of the punch apparatus are separated, and a device for adjusting a clearance between the die and the stripper during punching operation. The punch apparatus can open precisely almost straight very fine through-holes of a diameter of 100 ?m or less even in a sheet of thin, soft and deformable material.

Abstract: A punch die for punching and laminating simultaneously a plural number of thin sheets is disclosed. This punch die 10 comprises: a punch 10 being provided on a upper portion of a die, a die 12 being provided on a lower portion of a die and used for punching a material to be processed, a stripper 11 for guiding the punch 10 during punching operation, a device for laminating punched materials using the punch 10 as a laminating axis, a device for adjusting a relative position between the punch 10 and the stripper 11 when the upper and the lower portions are separated, and a device for adjusting a clearance between the die 12 and the stripper 11 during punching operation. The punch die can open precisely almost straight very finer through-holes of a diameter of 100 &mgr;m or less even in a sheet of thin, soft and deformable material.
