ABSTRACT:
A rod feeding and placement mechanism for use in apparatus for making hanging file folders comprises a magazine wherein a plurality of flat, elongated, metal rods are vertically stacked, one above another. A pair of laterally spaced-apart, horizontally disposed, slightly convergent, contra-rotating de-stacking screws located below the magazine engage the lowermost rod in the stack and advance or feed it laterally along a rod-path. Another pair of laterally spaced-apart, horizontally disposed contra-rotating top screws above the de-stacking screws then receive the rod from the de-stacking screws and advance or feed it further along the rod-path to an at-rest position located above a flat paperboard blank. Guide rails and magnetic strips support the rod as it advances along the rod-path. The rod is releasably maintained for a moment in the at-rest position by permanent magnets. An air-driven reciprocably movable placement member initially located above the at-rest position is then moved downwardly to engage a rod in the at-rest position and to move it downward to a specific location below the at-rest position, i.e., onto a glue strip along the edge of a stationary blank being fabricated into hanging file folders. The placement member has a port on the surface thereof which confronts the rod. The port is vacuumized as the placement member moves downward so as to hold the rod and prevent it from falling after it is disengaged from the permanent magnets. Just prior to upward reciprocal movement of the placement member, the ports are pressurized to release the rod from the placement member.
