ABSTRACT:
Bag handling apparatus for sequentially selecting bags from a supply thereof and positioning them for subsequent opening and filling has a vertically-movable slider positioned above a stack of horizontal closed bags. A carriage is pivotally secured to the slider and by links to a fixed point. Upward movement of the slider causes the carriage to be moved angularly from a downwardly directed position adjacent the stack of bags enabling the carriage to pick up a horizontal top bag to a forwardly directed position to cause the carriage to present the bag in a vertically-oriented position for subsequent opening and filling.
