Abstract: An apparatus for the application of strips of material to a heat-shrinkable web of wrapping in packaging machines with a tunnel furnace for the formation of the handle of the wrapped products. The apparatus has a wheel assembly supported to rotate about a horizontal axis with the wheel substantially tangential to a substantially horizontal section of the heat-shrinkable material strip, a feeder for the supply of a tape of adhesive material to the periphery of the wheel with the adhesive surface facing outwardly, a container for the supply, in spaced succession, of strips of material to the adhesive surface of the tape of adhesive material, a cutter for cutting the adhesive tape between two successive strips along the path of the wheel and a pressure roller which may be radially displaced with respect to the wheel to apply, by adhesion, the adhesive end areas of the sections of adhesive tape having a corresponding strip applied to them to the strip of heat-shrinkable material.

Abstract: An improved machine for wrapping continuously moving articles with heat-shrinkable material comprising a series of at least three horizontally aligned coplanar longitudinally spaced conveyors provided with a monodirectional continuous movement and with the adjacent sections of the two conveyors furthest downstream wound on at least a corresponding pair of return rollers supported by a support carriage which may be moved in an alternate manner parallel to the conveyor direction, means for supplying sheets of wrapping material and a pair of winding bar means caused by conveyor means to move continuously around the article being supplied on the intermediate conveyor such that during each rotation, while one of the bars takes a sheet of wrapping material and brings it across the path of a following continuously moving article so as to wind this material about three faces of this article, the other bar winds the material about the fourth face of the preceding article and, by means of the two adjacent conveyors fur

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.
