Said tool for installing a seal in a groove comprises a pad having a smooth planar upper sliding surface (20) and a lower surface on which are arranged successively, in the longitudinal sliding direction of the pad, a driving dog (21) and a ramp (25) that moves away from the upper surface (20) as it moves away from the dog (21).
摘要:
The invention concerns a machine for producing a nonwoven fabric comprising a conveyor (7) for transmitting a mat to means designed to compact same in thickness and means (8) 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.
摘要:
The invention relates to an equipment that comprises a first member (1) movable in a displacement direction and through which a fluid can flow, a second movable member (2), and a device (3) for projecting a jet of fluid, characterised in that the first movable member (1), when viewed in the direction of the jets of the projection device, is provided between the projection device (3) and the second movable member (2) at the jet projection point on the first movable member (1).

The invention relates to a machine for production of non-woven material, by projection of a spunbond of filaments from a tower (1 to 4) into the gap between two rollers (6, 7) and taking the layer formed in the gap on a horizontal conveyor (19), by means of application of a vacuum to the interior of one of the rollers (6).
摘要:
The invention concerns a method for producing a nonwoven web formed at least partly with hydrophilic elementary fibres which consist in: producing by carding a textile layer (10) which is then compressed and moistened; subjecting it to a bonding treatment using water jets acting at least against one of its surfaces; and transferring said bonded layer to a unit (32, 33) to be dewatered and dried. Said method is characterised in that, after the bonding treatment (20) with water jets and before drying and delivery, the pre-bonded and moistened layer is transferred to a supplementary unit (28) to be treated by the action of one or several series of water jets, said unit comprising a mobile suction surface in the form of a drum covered with an open-work structure (30) consisting of a wire-mesh fabric, comprising successive raised and recessed zones.

The invention concerns a water spraying device comprising a filter (10) and a perforated plate (15) which can be removed by being slid respectively through an opening (17) or a hole (22) emerging into a well (18) provided in the body (1), a pin (20) being inserted in the well (18) to maintain two plugs (19, 21) of the opening (17) and of the holes (22) when the pin is entirely inserted in the well (18).
摘要:
The invention relates to a compacting device comprising means (12) for positioning a roller (11) so as to alter the size of the arc according to which a first conveyor (4) is applied to a cylinder (15).
摘要:
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 (5); and finally, receiving the bundle of filaments in the form of a web on a mobile conveyor belt (7). The invention is characterised in that it consists of an assembly (6) arranged downstream of the outlet of the drawing assembly (5) and separate therefrom, said assembly comprising, arranged in the proximity of the drawing slot (F) outlet, a diffuser (10) comprising an intake zone (13) 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 (11) electrostatically charging the filaments before they are received on the receiving belt (7).
