ABSTRACT:
A product packaging machine incorporates a pair of conveyor belts which are continuously driven in a given direction at a selected speed. The conveyor belts are mounted on a reciprocable frame and are arranged such that the product being conveyed resides between the belts and a run of each belt firmly engages and transports the product. The belt runs engaging the product can be made to extend and retract in correspondence with the product being packaged reaching and completing a succeeding stage of packaging such as sealing.
