can be moved continuously through the third workstation 48 and on to the fourth workstation 50 referring now to fig7 the fourth workstation 50 is shown the fourth workstation 50 includes a fluid jet 92 at an end of a fluid line 94 that is controlled by a valve 96 the fluid jet 92 is directed downward again the term fluid is used in its engineering sense to encompass both gas and liquid in this example compressed air is again used the air jet 92 can be controlled by articles known in the art in this example a second laser 98 and a second electronic eye 100 are used in the same manner as in the first work station 44 again other controls for the air jet 92 such as limit switches and proximity switches can be used and other methods and articles for sensing the package assembly 10 will be known by those in the art the package assembly 10 can be moved continuously along by the conveyor through the fourth workstation 50 as the package assembly 10 is moved past the fourth workstation 50 the light beam is broken and the second electronic eye 100 sends a signal to the plc which then sends a signal to the second valve 96 the second valve 96 opens and compressed air is released to travel through the air jet 92 downward against the top portion 32 of the bag 14 the compressed air forces the top portion 32 of the bag 14 from its extended position downward into the container 12 such that the entire bag 14 is substantially inside the container 12 while a compressed air jet 92 is depicted other methods to push the top portion 32 into the container 12 such as a ram pushing down on.
