Abstract:

Carriers of the top gripping type and having downwardly depending side and end walls and stacked in collapsed condition in a hopper are fed in sequence by oscillatable feeder means which engages a lower planar element of the lowermost carton in the stack of cartons and draws that element outwardly from its associated face contacting element by means of inwardly extending projections fixedly mounted on the hopper and arranged to engage parts of the upper planar elements which coincide with edge notches formed on the lower planar element so that movement of the lower planar element away from the upper planar element initiates setting up of the carrier and also effects withdrawal of the lowermost carrier from the hopper.
