Abstract: Water needling is used to constantly subject the entire surface of a width of a goods line to water jets. However, it is also advantageous for units of commodity goods that are to be consolidated and optionally, if a cover nonwoven supporting these goods only needs to be consolidated around them or if a cover nonwoven is to be bonded around the goods. All possible patterns, such as line or strip consolidation, are advantageous. This is made possible by the invention, which provides for measures which specifically control, e.g. partially impede and/or interrupt the flow of the water jets from a water beam. This can occur by means of cover panels which advance with the line, supported by a screen or by means of a screen alone. Individually movable, computer-controlled nozzles are also advantageous for partial consolidation.

In a preferred embodiment, the decoration shell (7) comprises a counter-toothed ring (9) and the screening drum (6) comprises a toothed ring (8), said rings positively engaging in each other in such a way that a rotation of the decoration shell (7) and the screening drum (6) in relation to each other is prevented.

Abstract: A hydrodynamic needling apparatus for use on a textile web moving in a longitudinal web-travel direction has a first array of needle-jet orifices emitting respective needle-jet sprays extending in the travel direction between the respective orifices and the web, the array extending transversely across a full transverse width of the web at a substantially constant spacing therefrom with the sprays forming an angle greater than 0° and less than 90° with the web-travel direction. There is a similar second array of needle-jet orifices, but with it the orifices are directed at the same angle but oppositely to the sprays of the first array. Thus the sprays of the first array are directed to one side and the sprays of the second array to an opposite side from the respective arrays.

Abstract: A suction apparatus for an elongated water beam that extends transversely to and directs a liquid jet at a longitudinally passing textile web. The apparatus has a suction chamber extending transversely of the web adjacent the jet and having a perforated lower wall, means for withdrawing air from inside the chamber and thereby aspirating spray from adjacent the jet through the perforated lower wall, and an air-displacement body inside the suction chamber oriented for generally uniform suction across the perforated lower wall. Thus uniform suction effect is guaranteed across the entire width and/or length of the perforated suction surface formed by the lower wall.

Abstract: A suction apparatus for an elongated water beam that extends transversely to and directs a liquid jet at a longitudinally passing textile web has a suction chamber extending transversely of the web adjacent the jet and having a perforated lower wall. Air is withdrawn from inside the chamber to aspirate spray from adjacent the jet through the perforated lower wall. A slot passage opens at a location between the liquid jet and the suction chamber. A blower supplies air at superatmospheric pressure to the slot passage and therethrough to the location between the liquid jet and the suction chamber.
