Abstract
An apparatus (10) is disclosed including fixtures (32) mounted to carrier bars (30) removably secured to roller chains (24) extending in parallelogram-shaped closed loops. In a first, vertical portion of the closed loops, bags (12) are loaded into the fixtures (32) in a folded condition by a loading device (50). Guides (274) prevent the bags (12) from moving from the fixtures (32) when the fixtures (32) move from the first, vertical portion to a second, horizontal portion. The bags (12) are opened by suction cups (104, 106) and filled with product and then collapsed and sealed in the horizontal portion. Guides (184) prevent the bags (12) from moving from the fixtures (32) when the fixtures (32) move from the second, horizontal portion to a third, vertical portion and bend the portions of the bags (12) extending out of the fixtures (32) at a nonlinear angle to the fixtures (32). The bags (12) are ejected from the fixtures (32) in the third, vertical portion by reciprocal pushing plates (172, 174). The bags (12) are ejected into pockets (186). Lugs (230) extending from lands (228) push the bags (12) from the pockets (186) in an inverted position as the lands (228) move from an inner position to an outer position. The free ends of fingers (294) abut with the bags (12) as the lands (228) move from the outer position to the inner position to position the bags (12) on a conveyor (200) and under slide bars (240).
