Abstract
The present invention is a system for loading and dispensing flexible thermoplastic bags having at least two oppositely disposed walls movable with respect to each other to provide an open mouth for packing. The system includes a bag supply support which supports a supply of bags with one of the walls facing a packaging work area for opening the bag. The system also includes a bag opening means having a bag-attaching element and a pivotal arm on which the bag-attaching means is disposed for contacting the bags. The arm is actuable between a bag-engaging position wherein the bag-attaching element contacts an exposed wall of the bag and attaches it. The arm is also actuable to a bag-loading position wherein the bag-attaching element maintains the attached wall a distance away from a non-attached wall for loading.
