Title:
METHODS OF MANUFACTURING METAL PART AND SHEET RETAINING FOIL AND PRINTER
Document Type and Number:
WIPO Patent Application WO/1999/046068
Kind Code:
A1
Abstract:
Methods of manufacturing a metal part and a sheet retaining foil capable of reducing manufacturing costs and improving production efficiencies by forming them, even if they are fine, only by plastic working such as stamping, and a printer incorporating the foil as a sheet feed mechanism; the method of manufacturing a metal part by performing a plastic working on a metal sheet, comprising a first forming step of performing blanking for roughly forming at least part of an outline shape of a metal part, a second forming step of performing thinning by surface-extruding at least an outline edge portion and a third forming step of reforming the outline shape by blanking.
