Abstract
Abstract A device for forming containers into prismatic packages and thereafter to convey and discharge them utilizing a plurality of U-shaped trays mounted at intervals on an intermittently moving conveyor and is passed by the conveyor between two movable lateral mold plates and under an upper mold plate to form the package molding station, the container being pressed against the upper mold plate by rendering the conveyor vertically oscillatable around a pivot away from the molding station.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
A device for forming containers into prismatic packages and to thereafter convey and discharge them, said device comprising: two lateral mold plates movable towards each other; an upper mold plate positioned above said lateral mold plates, said three mold plates forming a molding station; a plurality of U-shaped trays to receive said containers; a vertically oscillatable and intermittently movable conveyor to lead said trays in succession through said molding station; first actuating means to press a container in one of said trays against said upper mold plate by lifting a free end of said conveyor; second actuating means positively associated with said first means to lift said lateral mold plates concomitantly with said upward lifting of the conveyor and press them against the two sides of an unformed container; Geneva motion means associated with said first and second means, to stop said conveyor when a tray with an unformed container reaches the location of said mold plates and during said container-molding operation and remove it sucessively from said station to convey another tray to said molding station.
Claim 2
Independent Claim
177 words
A device for forming containers into prismatic packages and to thereafter convey and discharge them, said device comprising: two lateral mold plates movable towards each other; an upper mold plate positioned above said lateral mold plates, said three mold plates forming a molding station; a plurality of U-shaped trays to receive said containers; a vertically oscillatable and intermittently movable conveyor to lead said trays in succession through said molding station; first actuating means to press a container in one of said trays against said upper mold plate by lifting a free end of said conveyor; second actuating means positively associated with said first means to lift said lateral mold plates concomitantly with said upward lifting of the conveyor and press them against the two sides of an unformed container; Geneva motion means associated with said first and second means, to stop said conveyor when a tray with an unformed container reaches the location of said mold plates and during said container-molding operation and remove it sucessively from said station to convey another tray to said molding station.
Claim 3
Independent Claim
49 words
A device according to calim 1, wherein said conveyor has two pairs of sprockets and said conveyor is oscillatable around a shaft of one of its sprocket pairs and said first means are a cam and lever unit linked to said conveyor to impart to it said oscillating motion.
Claim 4
Independent Claim
49 words
A device according to calim 1, wherein said conveyor has two pairs of sprockets and said conveyor is oscillatable around a shaft of one of its sprocket pairs and said first means are a cam and lever unit linked to said conveyor to impart to it said oscillating motion.
Claim 5
Dependent Claim
112 words
A device according to claim 1, wherein said second means comprise two vertically reciprocable parallel rods, a lever for each rod linked with one end to said rod and pivoted with its other end to a stationary support, a pin on each rod and rigid with it and engaging in a curved slot provided in a stem of each of said lateral mold plates, the end of each stem being hinged to said levers, whereby the upward movement of said rods will lift said lateral mold plates and swing them against the sides of said container, while the downward stroke of said rods will invert the motion of said lateral mold plates.
Claim 6
Dependent Claim
46 words
A device according to claim 1, wherein said upper mold plate comprises two jaws which are horizontally reciprocable from an open position permitting the passage of an unformed container into a tray underlying said jaws, to a closed position, wherein they form said upper mold plate.
Claim 7
Dependent Claim
26 words
A device according to claim 4, wherein said jaws are cutting jaws, which in their closed position sever said unformed container from those upstream of it.
