Abstract

A stitching method and a wire stitcher having a stitching head for stitching sheet-like materials using annular-eyelet staples, includes a staple support with a supporting body in the stitching head. The staple support supports a region of the annular eyelet during a driving-in operation and is moved out of the annular eyelet only when legs of the staple passing through the sheet-like material, have been largely bent over.
