ABSTRACT:
A turntable comprising a plurality of transfer roller assemblies of the type disclosed in U.S. Pat. No. 3,804,230. The transfer roller assemblies are mounted in two parallel ranks in planar array, and means are provided for controlling the direction of rotation of the cylindrical rollers and stub rollers in selected subsets of the planar array so as to impart rotary and/or translational motion to an object positioned on the array. A center pivot pad and means for selectively urging the center pivot pad upwardly against an object positioned upon the transfer rollers may be provided to provide resistance to unwanted translation by the object.
