Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
179 words
In a machine for packaging elongated articles having a plurality of work stations, wherein a package is formed from a blank which is automatically folded, filled and closed, comprising in combination: a rotatably disposed conveyor wheel arranged in a vertical plane perpendicular to its axis of rotation, said wheel having a plurality of radially extending pockets provided along the periphery thereof; each said pocket being defined in part by a forward and a rear wall, at least one of said walls being pivotably arranged within said pocket and effective to temporarily hold the blank in a clamping position; a plurality of folding and blank closing tools operably associated with said conveyor wheel; radially movable slides operably associated with said wheel to rotate therewith and arranged adjacent to a pocket; a packaging material feeder disposed parallel to the axis of rotation of said wheel and including means to sequentially cut the blanks from a continuous web; and a pair of tongs pivotably mounted between said wheel and said feeder for transferring the blanks at right angles to the conveying direction.
Claim 2
Dependent Claim
