An apparatus is provided for producing nonwovens. The apparatus includes a card drum that is rotatable in a first direction of rotation, a transfer cylinder that is rotatable in a second direction of rotation opposite to the first direction of rotation, at least one doffer, at least one condenser, at least one stripper roll, a first endless conveyor belt, a suction drum and a second endless conveyor belt.

Apparatus and method for producing nonwovens

A water extraction facility comprising a suction box having a suction opening and a chamber () arranged above the suction opening by means of a connector () and a perforated sheet metal element () creating head loss is mounted in the connector ().

Water extraction facility

An installation for drying a non-woven web includes a device (), a diffusion chamber () having an outlet fitting () in which there is mounted a perforated sheet () creating a drop in pressure.

Installation for drying a damp non-woven web

An installation for drying a web of non-woven material includes a fan (), a heating oven (), an outlet pipe (C) which puts the outlet of the oven () in communication with the intake of the fan (), a branch pipe (C) branching from the inlet pipe (C) upstream of the heat source () putting the pipe (C) in communication with the inlet of a drying device (), a pipe (C) for the extraction of air from the drying device () and a humidity level probe () mounted in the extraction pipe (C).

Method and installation for drying a damp web

The invention concerns an installation for producing a spunbonded fabric web comprising a diffuser defining for the filaments a passage with diverging cross-section, and mounted a certain distance from the slot attenuator, and a conveyor for receiving the filaments coming out of the diffuser. The uniformity of the web is enhanced by means of a device separating the filaments by electrostatic process mounted at a higher level than the bottom of the passage.

Installation for producing a spunbonded fabric web whereof the diffuser is distant from the drawing slot device

The invention concerns an installation for producing a spunbonded fabric web comprising a diffuser defining for the drawn filaments a passage with diverging cross-section, and mounted a certain distance from the slot attenuator, and a conveyor receiving the filaments coming out of the diffuser. The uniformity of the web is enhanced by means of a device separating the filaments from each other by electrostatic process mounted at a higher level higher than the bottom of the passage.

Installation for producing a spunbonded fabric web with filament diffuser and separation by electrostatic process

The invention concerns a device for opening and distributing a bundle of filaments when producing a nonwoven textile web by a technique which consists in: extruding melted organic polymer through a die perforated with holes, so as to form a bundle or curtain of filaments; then directing the extruded filaments by drawing by means of one or several fluid jets; and finally, receiving the bundle of filaments in the form of a web on a mobile conveyor belt. The invention is characterised in that it consists of an assembly arranged downstream of the outlet of the drawing assembly and separate therefrom, said assembly comprising, arranged in the proximity of the drawing slot outlet, a diffuser comprising an intake zone shaped as a convergent nozzle extending over the whole width of the installation opposite the drawing slot outlet producing the web, extended by a divergent nozzle, said assembly being associated with a ramp electrostatically charging the filaments before they are received on the receiving belt.

Device for opening and distributing a bundle of filaments when producing a nonwoven textile web

A mechanism for the treatment of materials by pressurized water jets includes a body ( ) for supplying water under pressure which includes a feeding chamber ( ) extending over the whole length of the body, and wherein water under pressure is fed to the feeding chamber through a filter ( ). The body also includes a distributing zone for distributing water under pressure over a whole treatment length against a plate ( ) provided with micro-perforations which define water needles ( ) directed against the surface (S) of the material to be treated. The material is supported by a carriage element subjected to a suction source eliminating the treatment water. Further, water transfer from the intake chamber ( ) to the perforated plate ( ), is done through a channel ( ) with a rectangular cross-section extending over the whole length of the injector, from the periphery of the feeding chamber ( ) up to the surface or the perforated plate ( ), wherein the spacing between the side walls ( ) of the channel and the height thereof produces a unidirectional and stable stream of water without turbulence.
