Apparatus and method for placing bags over insertion tube in bale enveloping apparatus

摘要

An apparatus for placing preformed bags having an open end and a closed end over an insertion tube for inserting a bale therethrough and into the bag. A plurality of fingers are inserted into the bag open end and are extended for engaging the bag. The fingers and bag opening are traversed to the tube thereby inserting the tube end into the bag opening. The fingers are retracted and removed from the bag. The insertion tube is expanded thereby engaging the interior surface of the bag. Roller drive wheels are placed on the bag over the insertion tube and are rotatably driven and are traversed along the insertion tube for collecting the bag thereon. The roller drive wheels and the plurality of fingers are carried on a common assembly movable along the insertion tube.
