Abstract: A nonwoven production machine includes a spun-bond tower for extruding filaments and associated apparatus for forming the filaments into a web that is consolidated by water jets, a web that is calendered and then softened by water jets, or a web that is only calendered.

Abstract: The invention concerns an installation for producing a nonwoven fabric comprising a spun bond lathe depositing a web of filaments on a first conveyor, the mat being consolidated on a first mobile element by entangling means. The invention is characterized in that it comprises means for passing, without any change in ratio, the mat of filaments on a first mobile element whereon the mat is consolidated by hydro-entangling means.

Abstract: This non-woven production installation comprises a spunbond tower (1), a device (7, 8) for consolidation by means of jets of water and a device (9, 10) for perforating by means of jets of water, the perforating device comprising three rows of jet outlet orifices.

Abstract: This device comprises a drum having a lateral surface through which fluid can pass, and two flexible belts (2) which pass over the lateral surface of the drum (1) at a distance from one another, each of them on an idle guide roller (3) of its own. Each roller (3) is mounted so as to pivot about a vertical axis (7).

Abstract: The machine for the production of a nonwoven comprises an expanding device which is arranged in-between a first consolidation by water jets and a second consolidation.

Abstract: The use, as the female part of a hook-and-loop fastener, of a nonwoven (25) which has openings, on the lateral walls of which the entangled filaments are intact.

Abstract: A drum for processing nonwovens has a perforated lateral surface and an interior divided into first and second compartments, respectively associated with first and second lateral surface portions of the drum. A partial vacuum in each of the compartments aspirates and secures a tangentially-engaged nonwoven preform against the lateral surface of the drum for further processing. The drum may be incorporated in a production unit or installation including a spunbond tower for spinning filaments to form the nonwoven preform for tangential delivery to the drum. The resulting nonwoven may thereby be provided with uniform properties.

Abstract: The inventive nickel drum comprises a first part whose lateral surface is provided with perforations at the first level thereof and a second part whose lateral surface is provided with perforations at the second level different from the first level. Said invention can be used for producing nonwovens.

Abstract: The invention concerns a machine for producing a nonwoven fabric comprising a conveyor for transmitting a mat to means designed to compact same in thickness and means designed to reduce the speed of the web while it is being compacted, by the compacting means, thereby obtaining an enhanced ratio of properties lengthwise relative to crosswise properties.
