There is disclosed a carding cylinder (10) having an internal cooling system arranged to route a flow of coolant to predetermined regions of the cylinder which require cooling and which comprises: a shaft (12, 13) on which the cylinder (10) is mounted; a coolant flow path (15, 17) arranged within the cylinder (10) and having an inlet end and a return end; a coolant inlet (16) and a coolant outlet (18) provided in the shaft and communicating respectively with the inlet and return ends of the coolant path (15, 17); and a centrifugal pump (14) mounted on the shaft (12, 13) to rotate therewith and having a pump inlet communicating with the shaft outlet (18) and a pump outlet communicating with the shaft inlet (16), whereby the pumped supply of coolant to the cylinder is substantially self-adjusting to suit cooling requirements which change as a result of change of cylinder speed. |
