Embodiment Construction
[0042] The drawing shows a plant for the production of nonwoven products made of continuous filaments, in which there is a spinning device 1 configured as a spinneret for spinning the filaments and a cooling device for cooling the filaments. Furthermore, a depositing screen 3 is provided, on which the filaments can be deposited in a depositing region 4 to form a nonwoven web 5 . Expediently and in the embodiment according to the figures, the apparatus is a spunbond apparatus in which a drawing device 17 is provided for drawing the filaments. Suitably, the continuous filament is a monocomponent filament made of at least one thermoplastic material. The cooling device 2 preferably and in an exemplary embodiment has a cooling chamber 18 through which the continuous thread is guided for cooling. Preferably and in an exemplary embodiment, two air supply compartments 19 , 20 are arranged one above the other on opposite sides of the cooling chamber 18 , from which air supply compartm...

Abstract
The invention relates to an apparatus for manufacturing a nonwoven article made of continuous filaments. A spinning device for spinning filaments and a cooling device for cooling the filaments are provided. Furthermore, a laying screen belt is provided, on which the filaments can be laid in a laying region to form a nonwoven web. The laying screen belt can be deflected in a deflection region from the transport direction of the laying screen belt by at least one needle roller. There is at least one subsequent device for the non-woven web connected downstream of the laying screen belt in the transport direction of the non-woven web. The nonwoven web can be separated from the lay-off screen belt upstream of a diverting region and then transferred to a subsequent device. In order to separate the non-woven web from the laying screen belt, at least one lifting roller is provided, which is arranged or can be arranged above the laying screen belt. By means of the at least one lifting roller, the non-woven web can be separated from the laying screen belt in a separation area which is arranged at a distance A from the needle roller.
Description
technical field [0001] The invention relates to a plant for the manufacture of nonwoven products made of continuous filaments, wherein there is a spinning device for spinning the filaments and a cooling device for cooling the filaments, wherein, in addition, there is a laying A deposit screen belt, on which the filaments can be deposited into a nonwoven web in the deposit zone. In this case, the depositing belt can be deflected in the deflection area by at least one needle roller from the direction of transport of the depositing belt, and there is a non-woven belt connected downstream of the depositing belt in the direction of transport of the nonwoven web. At least one subsequent device for weaving the web. The invention also relates to a method for transporting and handling a nonwoven web made of continuous filaments. Continuous filaments are distinguished from staple fibers by their virtually continuous length, which have significantly smaller lengths, for example 10 mm t...
