Under As the apples are I this vibratory movement ,of the brushesfthe apples will be thrown back and forth as they are progressively-fed forward by the conveyor belts and will be continuously turned so that during the progress through tharunways all surfaces. ofv the apples, ,their calyxes, will be presented to endvvise thrusting action of the brushes. Thisturning action of the apples is produced Ein partl,by the fact that the laterally spaced brushes 35 are located low do nZs thattheytend to make, the apples jump to and from the conveyor belts 25. Moreover, the turningof the apples is very greatly facilitatedby the fact that the centralportionso f the flexible coni lveyor belts25 are not solidly supported but are hungover the air channelslfi so that the belts themselves will be: vibrated vertically, thereby causing the apples to r jump upward and more 'or less againstgtheibristl'es of the overlying brushes, In a; flimsily V constructed 7 r machine, wherein the wholemachine is given quite violent vibratory movement, it: ,has
