Abstract: A carton flap gripping system including an adjustable pin holder is provided.

Abstract: A case sealing apparatus includes a frame structure including a case conveyance path extending from a case infeed station to a case outfeed station. First and second side conveying units extend between the infeed station and the outfeed station. The first and second side conveying units are moveable toward and away from the conveyance path for engaging opposite sides of cases to move cases of various widths from the infeed station toward the outfeed station. A lower tape head assembly is positioned along the conveyance path to apply tape to case bottoms. The lower tape head assembly is movable between a lowered position for taping and a raised position for changing tape. An upper tape head assembly is positioned along the conveyance path to apply tape to case tops. The upper tape head assembly is vertically movable to accommodate cases of various heights. A control system controls movement of the first and second side conveying unit, the upper tape head assembly and the lower tape head assembly.

Abstract: A gripping system uses a pin mounting block having at least one passage for accommodating holding pins of a holding pin member that cooperate with a dome to hold a laminate ply there between, the improvement being a releasable latch positioned to engage the pin member and hold the pin member in an operative positions and being releasable to release the pin member. Various forms of pin members may be used. In a preferred form a gripper is provided positioned adjacent to holding pins and moveable between a retracted position and an operative position wherein the gripper member grips the laminate ply.

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.
