Abstract
Abstract Method and apparatus for assembling a composite container which consists of a cup-shaped inner shell and a sleeve-type overwrap adhesively bonded to the exterior sidewall of the shell. Sleeve blanks are cut to shape, formed into their final configuration and inserted into a cup-shaped recess in a holder mounted upon an endless conveyer. The abutting edges of the inserted sleeve are axially aligned and the sleeve is accurately seated within the holder. The holder then carries the sleeve beneath a cup transfer mechanism which deposits the cup-shaped inner shell of the composite container into the sleeve. Prior to its insertion in the sleeve, the exterior side surface of the cup is coated with a suitable adhesive. After the cup is placed within the sleeve in the holder, the holder passes beneath a cup tamping mechanism which axially presses the cup downwardly into the sleeve to firmly bond the sleeve and cup to each other.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
161 words
Apparatus for forming and inserting a frusto conical sleeve into a holder having a frusto conical sleeve receiving recess comprising blank feeding means for feeding to a ready position a blank of sheet material shaped in the form of a development of said frusto conical sleeve, a frusto conical mandrel mounted for movement along an endless path extending through said ready position and a transfer station, drive means for driving said mandrel along said path to convey said blank from said ready position to said transfer station, conveying means operable in synchronism with said drive means for locating a holder adjacent said transfer station with the axis of the holder recess coaxially located relative to said mandrel, sleeve shaping means for wrapping the blank completely around the mandrel at said transfer station to form the frusto conical sleeve, and stripping means at said transfer station for axially stripping the sleeve from said mandrel and depositing the sleeve in the holder recess.
Claim 2
Dependent Claim
161 words
Apparatus for forming and inserting a frusto conical sleeve into a holder having a frusto conical sleeve receiving recess comprising blank feeding means for feeding to a ready position a blank of sheet material shaped in the form of a development of said frusto conical sleeve, a frusto conical mandrel mounted for movement along an endless path extending through said ready position and a transfer station, drive means for driving said mandrel along said path to convey said blank from said ready position to said transfer station, conveying means operable in synchronism with said drive means for locating a holder adjacent said transfer station with the axis of the holder recess coaxially located relative to said mandrel, sleeve shaping means for wrapping the blank completely around the mandrel at said transfer station to form the frusto conical sleeve, and stripping means at said transfer station for axially stripping the sleeve from said mandrel and depositing the sleeve in the holder recess.
Claim 3
Dependent Claim
72 words
Apparatus as defined in claim 1 wherein said sleeve shaping means comprises first means extending from said feeding means along opposite sides of said endless path to said transfer station for bending the blank partially around said mandrel as said mandrel moves from ready position toward said transfer station, and second means at said transfer station for completing the wrapping of said blank around said mandrel to form the frusto conical sleeve.
Claim 4
Dependent Claim
78 words
Apparatus as defined in claim 2 wherein the axis of said frusto conical mandrel extends in a direction normal to its path of movement, and said feeding means comprises a platform extending generally perpendicularly across said endless path and having an opening therethrough accommodating passage of said mandrel through said platform, and said blank advancing means is operable to advance blanks across said platform to said ready position wherein the blank spans said opening in symmetrical relationship thereto.
Claim 5
Dependent Claim
40 words
Apparatus as defined in claim 3 wherein said first means comprises a pair of guide rods fixed to said platform at opposite sides of said opening and extending therefrom in uniformly spaced relationship along opposite sides of said endless path.
Claim 6
Dependent Claim
62 words
Apparatus as defined in claim 3 wherein said platform lies in a generally horizontal plane, said path of movement of said mandrel being a circular path having a horizontal axis with the axis of the mandrel extending radially of said horizontal axis, said conveying means being movable along a second path extending beneath said transfer station with said recess axis extending vertically.
Claim 7
Dependent Claim
67 words
Apparatus as defined in claim 2 wherein said second means comprises a pair of star wheels mounted for free rotation about spaced parallel axes perpendicular to said path of movement of said mandrel, the periphery of said star wheels having semi circular recesses formed to cooperatively circumferentially surround said mandrel and the blank thereon when the mandrel axis passes through the plane containing the star wheel axes.
Claim 8
Dependent Claim
60 words
Apparatus as defined in claim 6 wherein said stripping means comprises a pair of wheels mounted for rotation at opposite sides of said path and spaced from each other to frictionally engage opposite sides of a sleeve on said mandrel and means for rotating said wheels in opposite direction to frictionally drive an engaged sleeve axially clear of its mandrel.
