Abstract:
1. A method for automatic loading of a paper bale bag having a top portion with an opening for loading and an apeture located in the top portion on one side thereof, comprising: hanging the paper bale bags on a single stationary protruding member sized to fit through the aperture in the bags thereby supporting the bags in a vertical orientation; activating a vacuum-operated engagement member at a first position to provide suction to engage a first one of the bags on a first side of the bag opposite the side of the bag having the aperature; reciprocating the engagement member to a second position while maintaining the activation of the suction to open the bag with the second position being spaced apart from the first position such that the engagement member opens the bag but does not remove the side of the bag containing the aperture from the protruding member wherein the bag is opened by the engagement member and the protruding member, the protruding member alone retaining the side of the bag containing the aperture while the bag is being opened; gripping left and right side portions of the open bag to retain the bag; and loading the first bag while the engagement device is at the second position and the side of the bag containing the aperture remains on the protruding member.
