Abstract
Abstract A bagging apparatus having means for advancing a bag in a flat or collapsed condition to a station where it can be opened for charging, means for retaining the bag in open position, mouth uppermost, and means for advancing the bag, when charged, and while retaining the charged bag in upright condition. Preferably air jet means are provided at the opening station for opening the leading bag of a spring-urged closely packed set of flat or collapsed bags on a holder means being provided for securing the front panel of that bag while the rear panel of said bag is retained on the holder. Conveyor means which can be stopped as required, e.g., at the opening and charging station, are provided for conveying the charged bag from that station.
