Abstract:
1. Suction device for fluids, especially on water needling machines, to which device a water manifold for generating fluid jets is attached, comprising a non-rotatably-mounted suction tube with suction holes arranged over the working length of the tube, through which holes the fluid is extracted by a partial vacuum generated in the tube, and wherein slide strips are arranged on both sides and parallel to the holes, and radially outside the tube, to support a transport means, such as a perforated drum, for the web-like material to be needled, characterized in that the inner circumferential surface of the suction tube is provided with a cleaning device which is insertable through a hole incorporated in a shaft at a front end of the suction tube, is movable within the suction tube and uses a cleaning fluid such as water to treat the interior side, at least of the suction openings of the suction tube.
