Abstract
A package-conveying apparatus, which is useful with a wrapping-machine of a type capable of wrapping a package with stretch film from a roll moving in an annular path, comprises an elongate table with two front ledges, a pair of endless belts for conveying a package toward the ledges, and a pair of package pushers. Each pusher includes a leg with a pivotable foot, a double-acting piston-cylinder mechanism for driving the leg frontwardly and backwardly, and a double-acting piston-cylinder mechanism for pivoting the foot upwardly into an operative position and downwardly into an inoperative position. In the operative position, the foot can engage a package to enable the leg when driven frontwardly to push the package from the endless belts onto and from the ledges. In the inoperative position, the foot clears a package on the endless belts when the leg is driven backwardly.
