Abstract
An automatic packaging machine comprises a spaced parallel pair of conveyor chains for transporting a plurality of pallets around an endless path. A pair of guide rails are connected between the conveyor chains for slidingly carrying each pallet. A plurality of control bars are slidably mounted on the guide rails. Two or more cam slots are provided at selected locations along the path followed by the conveyor chains in order to independently control the position of each of the control bars as a function of their instantaneous locations in the packaging machine. A stabilization support system built into the control bars provides enough play to dissipate centrifugal force and thereby enable the machine to operate at a higher speed. An X-Y mounting system may be provided in order to enable the pallets to undertake two dimensional motion. The control bars enable specific points in the surface area of the pallet to undertake specific motions which are independent of the motion of the pallet.
