SYSTEM AND APPARATUS FOR ERECTING CASES
First Claim
1. A case forming apparatus that erects cases from knocked-down case blanks, the apparatus comprising:
- a first jaw;
a plurality of stabilizer bars each having a first end mounted to the first jaw, the stabilizer bars being spaced radially from each other and forming concentric segments of circles centered on a pivotal axis;
a moveable second jaw mounted for movement on the pivotal axis relative to the first jaw between an open position where the moveable second jaw is substantially perpendicular to the first jaw and a closed position where the moveable second jaw is substantially parallel to the first jaw, the moveable second jaw including openings through which the stabilizer bars pass as the moveable second jaw moves between the open and closed positions;
wherein at least one of the stabilizer bars has a cross-sectional width that varies over at least one-third of a cross-sectional height of the at least one stabilizer bar.

Abstract
A case forming apparatus that erects cases from knocked-down case blanks includes a first jaw and a plurality of stabilizer bars each having a first end mounted to the first jaw. The stabilizer bars are spaced radially from each other and form concentric segments of circles centered on a pivotal axis. A moveable second jaw is mounted for movement on the pivotal axis relative to the first jaw between an open position where the moveable second jaw is substantially perpendicular to the first jaw and a closed position where the moveable second jaw is substantially parallel to the first jaw. The moveable second jaw includes openings through which the stabilizer bars pass as the moveable second jaw moves between the open and closed positions. At least one of the stabilizer bars has a cross-sectional width that varies over at least one-third of a cross-sectional height of the at least one stabilizer bar.
