    Abstract: Apparatus for applying plastic handles to tubular plastic bag stock. A drive mechanism feeds the bag stock through the apparatus intermittently in discrete lengths and each length corresponds to the length of a bag. A float piece is positioned inside the bag stock and is restrained to remain in a predetermined position as the bag stock is fed over the float piece by the drive mechanism. A handle transport mechanism feeds pairs of handles to respective positions one at either side of the float piece immediately adjacent respective outer sides of the bag stock and a clamping mechanism moves axially to apply a compressive force whereby the bag stock is clamped between respective handles and the float piece. A cutter is movable to pierce the bag stock inside the handles and an actuator is provided to move the clamping mechanism and the cutter assembly in sequence to first create said compressive force and then to pierce the bag stock. The float piece has a central main portion adapted to combine with the restraining means and a pair of relatively thin wing members dependent from the main portion in a substantially common plane. Heating elements and associated parts are provided to heat the bag stock for welding the bag stock to the handles from within the bag stock.

    Abstract: An apparatus and a method for attaching at least one carrying handle to a bag, such as a shopping bag, grocery bag, or the like. Individual handles are severed from a continuous web of handle material. Bags are conveyed at a predetermined velocity, with a longitudinal axis of each bag substantially perpendicular to the bag's direction of travel. Each carrying handle is transported proximate a front or back surface of an associated bag, and in a direction of travel wherein a longitudinal axis of the carrying handle is substantially parallel to the direction of travel of the bag, and substantially perpendicular to the longitudinal axis of the bag. The handle is transported at a velocity substantially equal to the predetermined velocity of the bag. The handle is applied to the bag when a handle accepting region of the bag contacts an attachment panel portion of the carrying handle.

    Abstract: The handles of bags, provided with legs, are cemented to both sides of the opening sides of the bags. The handles are U-shaped handles made of strip-shaped material. Parts of the handles are folded over onto the side walls of the bags and fastened with adhesive spots to the side walls of the bags or to the non-folded over segments of the legs. After the legs have been glued to the continuously conveyed bags, the handle parts are folded over onto the side walls of the bags around prerupture lines of the legs in the direction of transport. The handle parts are folded over by at least one fold-over rod extending at a right angle to the direction of transport.

    Abstract: An easy opening plastic bag includes a plastic front panel, a plastic rear panel, and plastic left and right end panels coupled to the front and rear panels. A plastic gusset is formed at the top of the bag and is joined to the front, rear, left, and right panels. A first frangible portion is disposed near a top of the front panel, and a second frangible portion is disposed near a top of the rear panel. The first and second frangible portions lie in a plane which allows a portion of the bag to rotate away from the remainder of the bag about an axis parallel to the plane. A third frangible portion is provided in the bag and extends substantially perpendicular to the plane of the first and second frangible portions.

    Abstract: This invention is a novel plastic bag and method of making it with a handle that extends upward through a folded-back top compartment, and the end of a front of the bag has a pocket with a similar folded-over top edge of the back of the bag. The bags of this invention are made from a continuous sheet, preferably a roll of plastic web that has its opposite side edges folded inwardly along opposite edges of the web to make the folded edges at the front and back sides of the bag. The web is then folded along its longitudinal center region with a gusset that forms the bottom of each bag. The bags have surfaces that are welded together to join areas of the front and of the back where necessary to weld plastic areas together, and certain areas do not weld where the plastic sheet is coated on areas that prevent heat applied to the plastic from fusing together.
