Abstract
A machine for forming individual packages from a web of preopened and interconnected bags one at a time is disclosed. A web is fed along a path of travel from a supply to a load station. A pair of nip rolls are positioned along the path near the load station. A printer is positioned along the path between the supply and the nip rolls. A nip roll drive is provided for rotating the nip rolls selectively and one at a time at a printing rate for the feed of the web when the printer is operating and at a faster feed rate for positioning a bag at the load station when the printer is not operating. A supply station tensioner is provided for tensioning a web along the path such that the printer when operating prints a section of a tensioned web.
