Abstract
The openable end of a collapsed bag is aligned in an alignment station on the base of the bag aligner machine. The bag is removed from a bag pickup station by a pick-off arm and moved to a preliminary position. At this point the bag is transferred to a bag holder which moves upwardly relative to the base to move the openable end of the bag into a bag-edge locator. This locator includes first and second alignment members which are interconnected in generally a V configuration and the bag openable edge is moved by a first motor into the open V end between the first and second alignment members to abut the closed V end under the urging of the first motor and additional urging of resilient means. This positively locates the edge of the bag so that it may be subsequently gripped, opened and then filled at a subsequent filling station.
