Packaging sealer printer

Abstract

A packaging sealer printer employing a bag sealing mechanism in a printer assembly. The sealer printer transports a web of bags past a printing head and to a filling station and sealer assembly. The bags are sequentially indexed during the transporting operation. At the printing head, information regarding the content and/or recipient of the bag is printed on the bag. The same information is displayed on a video screen when the bag is indexed to the filling station and sealer assembly for filling by the operator. The bag is then sealed by a pressure bar pinching the bag against a spring plate and heater bar. A transfer printing tape is interposed between printing head and the bag to be printed. A low voltage sensing finger rides upon the web of bags and is operative to sense the presence of uniformly positioned apertures along the web of bags to assure and maintain proper registration of the bags with the printing head and filling and sealing stations during operation.
