ABSTRACT:
A cutting head for a selective cutting machine includes internally-fed spraying means including a high pressure water control means which is designed in such a way that only spray nozzles adjacent to cutting tools that are actually cutting are supplied with water under pressure. The water under pressure is supplied from a boom to the rotating cutting head via a piston whose free end surface is pressed, by the pressurized water, against a control surface provided on the cutting head. Said free end surface is formed with a control opening which overlaps control ducts provided in the control surface during rotation of the cutting head, thereby controlling the flow of pressurized water to the various groups of spray nozzles. Non-return valves, which keep the control ducts closed, when they are not aligned with the control opening of the piston, are located in the control ducts.
