ABSTRACT:
High speed turning of elongate confectionery bars through 90.degree. is executed in two stages. The bars are turned through an acute angle in a first stage by a timed blast of air from an air jet while the bar are in flight between first and second conveyors and through a further acute angle by a pair of diverging differential speed conveyors. The timing of the air blast is achieved by detecting the leading edge of the bar by sensors prior to projection. The orientation of the bar is checked by further sensors after initial transfer to the differential speed conveyors, and the relative speeds of those conveyors is adjusted if necessary to complete the turn.
