Abstract
An automatic bagging machine comprising a collector for receiving a predetermined number of articles to be placed in a single bag therein. A trap door is disposed under the collector. A first bag on a wicker is opened, filled through the trap door, and dropped onto a first bag support platform. A clamp retains a top end portion of the bag on a clamping surface after it has been filled and the support platform is displaced to a sealing station where a section of the top end portion of the bag, spaced from the mouth opening, is guided in a bag gathering mechanism to gather that section. The gathered section is then heat sealed. During the sealing operation, a second bag support platform is positioned under the trap door. After another filled bag is dropped onto the second support platform, both platforms are displaced with the sealed bag being retained by the sealing mechanism and supported for a predetermined number of time to cause the heat seal to properly fuse and thereafter release the bag onto a discharge conveyor.
