Abstract: The packaging machine for wrapping several articles (c) together includes an infeed section (12) with a conveyor (18) to continuously feed wrapper blanks (b) in a flat condition toward and out-feed section of the machine. Other conveyors (22,24) continuously feed a linear series of containers to be wrapped into longitudinal alignment with the wrappers, so that each container is placed above a blank. - A loading section (20) places each container in a wrapper base panel aperture (a) before passage to a forming station in which the blank panels are folded to complete the package. The containers enter the loading section above the wrappers. The latter are progressively raised to the level of the containers during conveying in synchronism to locate the containers in the apertures.

(11pp Dwg.No.0/2) - EP-149351 B A machine (10) for wrapping a plurality of cup-shaped containers (c) arranged in two rows in a wrapper (b) of the type having a base panel (p), side wall panels joined to the base panel along longitudinal side edges thereof, and top wall portions joined to said side wall panels along fold lines remote from said edges of the base panel and arranged to be folded into overlapping relationship, said base panel being provided with two rows of apertures (a) for receiving the lower portions of said containers and reinforcing tabs (t) struck from said apertures and joined thereto along fold lines remote from said longitudinal side edges of said base panel and substantially parallel thereto, which machine comprises, (a) means (18) for continuously feeding a series of wrapper blanks in substantially flat condition from an infeed section (12) toward an outfeed section (b) means for folding said reinforcing tabs out of the plane of said blanks into substantially upright position (c) means (22,24) for simultaneously advancing two linear series of containers into longitudinal alignment with said wrapper so that each container is moved into a position directly above said wrapper, (d) means (e) for causing each container to be located in one of said apertures while the containers and said wrapper are conveyed in synchronism through a loading section of the machine, (e) means for folding the upper portions of said reinforcing tabs outwardly to overlie the tops of the associated containers (f) means for folding the side walls into substantially upright position and folding one of the top wall portions into generally horizontal position to overlie the tops of adjacent containers (g) means (40) for applying adhesive to the exposed horizontal surfas of said reinforcing tabs and to said one wall portion (h) means for folding the other top wall portion into face contacting relationship with the exposed surfaces of said reinforcing tabs and overlapping relationship with said one top w USAB- US4571923 A The packaging method comprises continuously feeding a series of wrapper blanks in flat condition from an infeed section toward an outfeed section of a packaging machine, and folding reinforcing tabs out of the plane of the blanks into upright position. The method also involves simultaneously advancing two linear series of containers into longitudinal alignment with the wrapper and directly above it, and causing each container to be located in one of several apertures while the containers and the wrapper are conveyed in synchronism. - The method also comprises folding upper portions of the reinforcing tabs outwardly to overlie the tops of the associated containers, and folding side walls into upright position. After folding top wall portions they are secured together in overlapping relationship.
