Abstract: The invention relates to a device for hydroentangling and/or structuring webs that includes an suctioning rotating drum and a structured shell, including at least two rings which can be pushed on and attached to the drum, is disposed at a distance from the cylindrical surface of the drum around. A web can be at least partially looped around the structured shell. At least one water bar including a nozzle strip with a plurality of nozzles is arranged relative to the structured shell to entangle and/or to structure and/or to perforate the web by the water jets. The invention further relates to the structured shell.

Abstract: A method for reducing a disturbance on a signal path is provided. The disturbance is caused by a capacitance (203, 214)of a semiconductor switch (131-133) of an integrated circuit (130). The semiconductor switch (131-133) switches the signal path. The capacitance (203, 214) acts between the semiconductor switch (131-133) and a power supply terminal of the integrated circuit (130). According to the method, the power supply terminal of the integrated circuit (130) is coupled via an impedance (138, 139) to a power supply (137, 140).

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 ? of from 5° to 45°, preferably 15°, relative to the longitudinal axis of the basic drum (1).
