ABSTRACT:
A wrap-around packing machine wherein the packing station and the station which supplied prefabricated blanks are separated from each other by a treating unit having a pair of tools serving to provide successive prefabricated blanks with additional fold lines in positions depending on the dimensions of commodities to be wrapped. To this end, the tools are movable toward and away from each other by a reversible motor which receives signals from photocells monitoring the height of commodities to be packed while such commodities advance toward the packing station. The photocells are mounted on a carrier which is movable up and down by the reversible motor so that the photocells come to a halt when they assume certain predetermined positions with reference to the commodities whose height deviates from the height of previously supplied commodities.
