and B, the feed rollers, and emerge between B and 

 C, the megass roller. The distance between A and 

 B is so arranged that the canes shall enter with 

 sufficient freedom to ensure good feeding, and at 

 the same time be subjected to a certain degree of 

 pressure, while B and C are set as closely to-
