ABSTRACT:
A method and apparatus is disclosed for use in weighing products having circular or oval footprint configurations. A conveyor having a pair of parallel conveyor elements arranged to underengage the footprint only adjacent the periphery thereof transports the products one at a time across a planar surface of a weigh pan or scale device. The surface of the weigh pan is shaped and the transverse spacing between the conveyor elements is adjustable in order to permit lengths of the surface of the weigh pan engaged by the conveyor elements to be selected to correspond essentially to dimensions of differently sized products to be weighed.
