MANUFACTURE OF SHEET BUNDLE OF INK RESERVOIR

摘要

PROBLEM TO BE SOLVED: To provide a method of performing securely fitting lamination for an arbitrary necessary sheet of sheet bundles. SOLUTION: The manufacturing method of sheet bundles is done by repeating the formation of sheet bundles subjected to fitting lamination while being pressed by an outer periphery punch having a projection similar to a punch formed with a cut-raised part 21, and rotation of dies after the sheet bundles fitted and laminated reaches an arbitrary number of sheets in a process in which the sheets 20 are pressed in dies in a process of progressive press work.
