Abstract
An apparatus and method is provided for fabricating storage bags that have complementary sealing ribs out of stock material which may be a tubular extruded stock. When produced according to this apparatus and method, the storage bags have open mouths, that is, the sealing ribs are not engaged. The apparatus includes a separator bar to separate and disengage the sealing ribs prior to transversely joining the tube to form the side edges of the bag. Guide plates and a platen maintain alignment of the separated sealing ribs when the side edges are formed. The formed bags are then sequentially cut from the tube.
