摘要： 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.

摘要： A machine for making hanging file folders, each of which folders comprises a folded paperboard blank and a pair of support rods fastened to the upper edges of the folded blanks and includes a rod applicator mechanism comprising a conveyor for moving an unfolded flat blank having glue patterns thereon along a path; a mechanism for momentarily interrupting or stopping movement of the blank along the path; a pair of rod-dispensing magazines adjacent the path; and rod transfer mechanisms for transferring rods from the magazines and applying them to the glue patterns while the blank is stopped, whereafter blank movement resumes. The conveyor includes a pair of separable rollers between which the blank passes and by which it is advanced when the rollers are closed. The mechanism for momentarily interrupting movement of the blank effects momentary separation of the rollers and includes a stop member temporarily movable into the path of movement of the blank to arrest its progress after the rollers separate. Each rod transfer mechanism comprises a reciprocably and horizontally movable grooved rod-holding plate for removing a rod from an opening at the bottom of a magazine and a reciprocably and vertically movable rod applicator for removing (lifting) the rod from the plate groove, for then lowering the rod, and for then applying the rod to a glue pattern on the blank. The rod plate groove and rod applicator each have fluid ports therein which are connectable by appropriate valving to a fluid pump and a vacuum pump, alternately for temporarily holding a rod thereon during movement thereby and to then subsequently enable release of the rod therefrom.
