Device for bonding textile fibers by means of hot gases

The invention relates to a device for producing a nonwoven composite fabric. A nonwoven fabric layer is applied onto a support structure layer and connected to said layer by means of water jet needling. According to the invention, the following are provided:

Device and method for producing a nonwoven composite fabric

The invention relates to a suction device for liquids in hydroentangling machines, in which more than one water bar, which generate jets of liquid, are allocated to the exterior of the suction device. The suction device consists of a suction tube comprising one or more axial suction openings for each water bar, said openings being located along the working length of the tube. The liquid is sucked from the allocated water bar through said openings as a result of the negative pressure that is created in the tube. According to the invention, the suction openings that extend over the entire working width are configured to be sealed in relation to each respectively allocated water bar.

Suction device for liquids, in particular hydroentangling machines

The invention relates to a device for decorating and fixing a non-woven material () in the form of a web of endless fabric, said device comprising a screening drum () and a decoration shell () which surrounds the screening drum () from outside. The fibres () of the non-woven material, located on the decoration shell (), are needled and fixed according to the decoration formed by the holes of the decoration shell () by means of energy-rich water jets () or air flows. The invention is characterised in that the decoration shell () and the screening drum () are interconnected by mechanical means () that can be easily detached. In a preferred embodiment, the decoration shell () comprises a counter-toothed ring () and the screening drum () comprises a toothed ring (), said rings positively engaging in each other in such a way that a rotation of the decoration shell () and the screening drum () in relation to each other is prevented.

A nozzle beam formed with an annular groove is fitted with a seal ring by an apparatus having an elongated support bar, a pair of holders fixed on the bar spaced apart sufficiently that the seal ring can be stretched between them, and a release element for pushing the seal ring off one of the holders.

A drum for forming relief patterns on a surface of a textile web has a tubular jacket rotatable about an axis and having a substantially cylindrical outer surface centered on the axis and formed with an array of raised portions separated by lands and with a multiplicity of radially throughgoing holes. The holes are elongated and extend at angles between 20&#xb0; and 170&#xb0; to midplanes extending perpendicular to the axis, the web engaging the drum. Liquid jets are directed radially inward at the web where it engages the drum for impressing the raised portions into a face of the web. Liquid is aspirated inward through the holes from the web where it engages the drum.

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.

Method for hydrodynamically subjecting a goods line, optionally with finite preproducts, to water jets and nozzle device for producing liquid jets

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&#xb0; and less than 90&#xb0; 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.
