Material which can be processed: short fibres, medium fibres, polyester, wool and cotton. The CD2-S2 and CD2-S4 is a special carding machine suitable for all materials in short fibres (wool, cotton, waste, etc.). and in particular to polyester fibres. It is composed by two stages of carding with adjustable speed (from 2,400 to 3,800 revolutions per minute) and you can change the distance between the two discs and the caps of carding, to better adapt the machine, depending on the type and length to be processed. The particular shape of the hopper prevents accidental contact of hands with moving parts. The machine can be switched on from a remote location for better integration in a system composed of several machines. You can connect two machines in series (for a total of 4 stages of carding) to get a better opening of the fibres (thereby improving performance) and increase the production. The two machines keep the variation of speed in an independent way.
