Zusammenfassung:	A method of forming bag precursors and individual bags from a supply of polymer sheeting is disclosed. The method includes the steps of folding a polymer sheet in half to form a bottom edge at the fold, two sheet faces, and a top edge opposite the fold; inserting a pre-closed zipper into the top edge between the two folded sheets and fixing the zipper to the inside surfaces of each sheet and with a header space between the zipper and the top edge of the sheet; thereafter opening the zipper and separating the sheets at the zipper; maintaining the open zipper portions and sheets in alignment and applying reinforcing patches to the interior of each sheet at the opening; and thereafter reclosing the aligned zipper portions
