ABSTRACT:
A case forming machine for erecting cases from knock down case form to an open form and move an opened case downward to a bottom forming station using a fixed and a moveable jaw system is improved by providing a plurality of radially spaced, concentric stabilizer bars fixed to the fixed jaw and arranged to form concentric segments of circles centered on the pivotal axis of the moveable jaw and having their bottom edges in a radial plane relative to the pivotal axis. Also provided is a micrometer type adjustment mechanism that is used for adjusting the gap between the fixed and moveable jaws when the jaws are in the parallel pick-up position.
