Besidesslicing the cane, this appliance serves to beat down and to level the mattedmass of material, thus aiding in maintaining an even feed. The shredder is a torsion machine, which acts on the principle of passing thecane between two surfaces moving at different speeds. The effect of this is to 330 CHAPTER XI twdst the wall of the cyUnder, separating the fibro-vascular bundles whichmake up the wall and destroying the resistance to external pressure. Thefirst patent of this type is due to Faure (3003 of 1879) who employed a rotat-ing drum, on which was cut a series of heUcoidal teeth operating in com-bination with a fixed counter plate set eccentric on the drum. Shreddersas actually used, however, have employed two drums, co-acting with eachother, where the upp
