ABSTRACT:
A plant for wrapping products has a packaging machine for packaging groups of products in single packages and a machine for wrapping these packages with a strip of heat-shrinkable material. An apparatus for stacking these single packages to be wrapped is disposed between these machines and comprises a first horizontal conveyor and pair of conveyors adjacent and parallel to the opposite sides of this first conveyor. Each conveyor of the pair is formed by a plurality of conveyor units with their respective upper branches or stretches at different levels and each provided with uniformly spaced lifters disposed opposite one another in a symmetrical manner. These conveyor units have a continuous movement, to maintain the lifting means symmetrically opposite one another in a constant vertical position and the lifters are caused to oscillate about a respective horizontal axis for the takeup and discharge of the single packages being stacked.
