A flow wrapping apparatus displaces a number of packs from a first location where the packs are self-standing on their lower region to a second location where the packs are on edge to form a substantially horizontal stack. The apparatus includes first and second conveyors with a number of individually displaceable hands. The hands of the first conveyor displace packs from a first location where the packs are self-standing on their lower region to a second location where the packs are on edge. At least one of the hands of the second conveyor cooperates with at least one of the hands of the first conveyor to hold packs on their edge to form a substantially horizontal stack. A pair of individually displaceable hands of the second conveyor displace the stack towards a flow wrapping station.
