A packaging machine for inserting semi-compressible articles into preformed bags comprises an upper gripping member, a lower gripping member which can be raised towards the upper gripping member to clamp therebetween extension portions of a stack of bags, the lower gripping member mounting means for temporarily retaining the bags of the stack of bags relative to the lower gripping member and means for inserting articles through the open end of the upper bag. The arrangement is such that the gripping members grip the extensions of the bags so that articles can be inserted into the upper bag, the articles undergoing limited compression against the end wall of the bag after which the clamping pressure is released. The filled bag then moves relative to the lower gripping member, the force applied to the bag being sufficient to overcome the restraint imposed by the temporary retaining means. |
