ABSTRACT:
A stationary shaft (17) is electrically connected to a roller (18) by a contactor (31) having a first section in the form of a wire loop (32) seated in a groove (32) and a second pointed section (36,37) seated within a conical recess (38) formed in the end face of the shaft and having an apex axially aligned with the axis of the shaft. An intervening section (34) is dimensioned to resiliently bias the pointed section (36,37) into firm engagement with the apex of the conical recess to make good electrical contact with a minimum degree of friction.
