The conveyor belt 2 is associated with a chassis 1 which can be displaced vertically on a pair of lateral guides 3 which are closed at their upper end, forming a type of bridge which frames the aforesaid conveyor belt 2, the aforesaid chassis being suspended inside said guides 3 by means of chains or other similar elements which, associated with an actuating means, such as, for example, a manual actuation wheel, allow said chassis to be pulled or retracted, with the resulting rise or fall of the conveyor belt 2 in order to adapt it to various sizes of bag. In addition, the actual chassis 1 also has secured to it the striker/compactor mechanism 18 which acts on the bags in the stage in which they are filled so that, in parallel with the height-adaptation of the conveyor belt 2, the height-adaptation of the aforesaid striker/compactor 18 is also automatically brought about. <IMAGE>
