Abstract
The invention relates to an apparatus for hydrodynamic entanglement of non-wovens, wovens or knits, comprising a basic drum (1) having a multiplicity of holes (4), on which basic drum (1), spaced apart therefrom, there is arranged a structured drum (6), the spacing between the basic drum (1) and the structured drum (6) being arranged to be produced by a plurality of wires (5, 5′, 5″, 5′″, . . . ) which are arranged on the surface of the basic drum (1) and which are at least in part in material-based connection with the basic drum (1), the wires (5, 5′, 5″, 5′″, . . . ) being arranged in parallel to one another on the surface of the basic drum (1), characterised in that the wires (5, 5′, 5″, 5′″, . . . ) are arranged on the surface of the basic drum (1) at an angle α of from 5° to 45°, preferably 15°, relative to the longitudinal axis of the basic drum (1).
