Abstract:
The suction unit at a water jet needling machine, to bond nonwoven fabrics and the like, has a suction tube with a number of axially aligned suction openings for each water beam. The suction openings along the whole working width can be closed in relation to their associated water beams, by a shoe moving through the tube without any openings. At the sliding mechanism a closure rail (22) is in horizontal recesses (7',8') in the vertical walls (7,8) flanking the suction slit (9), radially inwards from the cleaning bar, with a slit passage (23) for the extracted water. Piston units (24) are on both sides of the closure rail, along its length, with a hydraulic drive action to push the rail into the recesses.
