A method for producing a composite nonwoven fabric having at least two layers, wherein a first layer is made of long fibers, and a second layer is made of short fibers. The method includes attaching, in a production line, the short fibers of the second layer to the long fibers of the first layer in a wet laid process via a headbox. The headbox has a round flow or cross flow distributor with a rotating or static turbulence generator.

Method for producing a composite nonwoven fabric and device for producing a composite nonwoven fabric

A system for bonding a first layer having short fibers with a second layer having long fibers into a nonwoven web. The system includes a belt, a headbox, a depositing belt with a delivery strand, a transfer belt with a receiving strand, a device, a pre-bonding unit, and a bonding device. The short fibers are deposited on the depositing belt to form the first layer with the headbox. The transfer belt transfers the first layer to the second layer. The pre-bonding unit has spaced-apart compacting devices which act on the transfer belt to form a lower strand of the transfer belt there between. The bonding device is arranged between the compacting devices. The bonding device bonds the first and second layers. The compacting devices and the bonding device are operatively connected to one another so that they are each always either in an operating state or in a resting state.

System for bonding layers comprising fibers to form a nonwoven web

An apparatus for bonding a first layer having short fibers with a second layer having long fibers into a non-woven web. The apparatus includes a first circulating belt on which the second layer is depositable and displacable, a second circulating belt via which the first layer is transferable at a transition point to the second layer, a pre-bonding unit arranged directly behind the transition point, and a bonding device. The pre-bonding unit has compactors which are spaced apart from one another. The compactors act in one region on the first or second circulating belt. The bonding device is arranged between the compactors and bonds together the first and second layers. The compactors and the bonding device are integrated into the apparatus to together be in an operating state when the first layer is transferred using the second circulating belt.

Apparatus and method for bonding layers comprising fibers to form a non-woven web

A system for bonding at least one wet-laid or dry-laid fiber layer to form a nonwoven web. The system includes a conveyor having a circulating belt which has an upper strand arranged so that the at least one wet-laid or dry-laid fiber layer is deposited and displaced on the upper strand in a production direction, a first bonding device which bonds the at least one wet-laid or dry-laid fiber layer when on the upper strand, a second bonding device arranged so that the at least one wet-laid or dry-laid fiber layer is bonded after leaving the upper strand, and a transfer device which feeds the at least one wet-laid or dry-laid fiber layer to the second bonding device.

System for the bonding of at least one wet-laid or dry-laid fiber layer

A method for an assembly of a device includes providing a nonwoven production device having a supporting structure in a first transport container, the nonwoven production device being pre-assembled, providing an auxiliary unit in a second transport container, removing the nonwoven production device having the supporting structure from the first transport container, removing the auxiliary unit from the second transport container, releasing the nonwoven production device from at least one part of the supporting structure and positioning the nonwoven production device at a top side of the supporting structure, and establishing a fluidic connection between the nonwoven production device and the auxiliary unit.

Device for the production of nonwoven fabric webs and method for installing such a device

A device for the production of nonwoven fabric webs. The device includes a nonwoven production device comprising a supporting structure, and an auxiliary unit comprising at least one liquid tank and a platform arranged on a top side of the auxiliary unit. The nonwoven production device is arranged on the supporting structure in an assembled state. The nonwoven production device and the auxiliary unit are arranged in relation to each other so that, for at least one of assembling, operating, and repairing the nonwoven production device, access to the nonwoven production device is provided from the platform.

Method for producing wet-laid non-woven fabrics, with which an aqueous suspension comprising fibres is laid down on a screen and is dewatered using suction boxes under the screen to form a sheet of non-woven web which is removed from the screen and guided to at least one subsequent treatment unit before the non-woven web can be wound, and transferring of the non-woven web from the screen to the at least one subsequent treatment unit and/or transferring of the non-woven web to interfaces between treatment units on the start of production and/or after an interruption in production, using a web feed, wherein web is fed via a temporarily closed draw of a free draw between the screen and the at least one subsequent treatment unit and/or of a free draw at an interface between treatment units, and the respective temporarily closed draw is produced via air flows, which lift off an end feeding strip as part of the running non-woven web by blowing, adhere same to a transport path device by generating negative pressure and lift up same at the following treatment unit by suction.
