The two revolutions serve to translate the stoker shaft carried by the traveling brackets 52 and 54 to the next adjacent column of rounds together with the last extracted round of the previous column; i.e.
  • the stoker shaft does not rotate, even though it is meshed with the continuously rotating acme screw shaft, because the rotation of the stoker shaft caused by the translation of the stoker shaft along the longitudinal axis of the acme screw shaft exactly cancels the rotation of the stoker shaft caused by the rotation of the acme screw shaft about its own axis.
