ABSTRACT:
A card package production system (20) for producing card packages (22) with cards (26) mounted to bifold carrier forms (24) with a pair of parallel, spaced, preweakened fold lines (33) and (34) dividing the body (32) of the carrier forms into leading end (35), middle (36) and lagging end (37) sections, a card carrier form folding apparatus (30) having a stop member (46) located extending downwardly into a blocking position along a folding path (44), a plurality of rollers (38)(39) and (40) for moving the carrier forms (24) along the folding path (44) and into the stop member (46) to buckle the leading end (35) and middle section (36) away from the folding path (44), a pushing member (56) driven by an electric motor (57) engaging the lagging end section (37) to push the carrier form (24) along the folding path (44) to pivotally swing the stop member (46) to a nonblocking position enabling the middle section (36) to fall back against the lagging section (37) folding the carrier (24) along fold lines (33) and (34) a transporting pushing pin member (74) interconnected with a circulating chain linkage (76) extending through a slot opening (242) in the folding path (44) to turn the folded carrier (24) about a pivot pin (220) for ejectment to a folded carrier outlet station (240).
