ABSTRACT:
A tobacco shredding machine wherein the cutting edges of orbiting shredding knives are sharpened by the undulate annular surface of a grinding wheel which is reciprocated forwardly and backwards in parallelism with the axis of the holder for the knives and is retracted from the circular path of the cutting edges during each return stroke of its support. The speed of forward movement of the support while the grinding wheel sharpens the cutting edges is such that the support covers during each revolution of the holder a distance which equals or is a whole multiple of the width of an undulation on the grinding surface. The axes of the grinding wheel and of the holder for the knives are located in a common plane.
