Embodiment Construction

[0049]figure 1 Shows a device according to the invention for the production of non-woven fabrics 1 from thermoplastic fibers, wherein the fibers are preferably continuous filaments 2 in the embodiment, more precisely, according to recommendations and in the embodiment have eccentricity The core-sheath-structure of the two-component filament. The continuous filament 2 with an eccentric core-sheath structure which is particularly preferred within the scope of the present invention will also be explained in detail below. According to the recommendations and in the embodiments, the device of the present invention is configured as a spunbond device for manufacturing spunbond nonwoven fabrics.

[0050]figure 1 A spinning device 10 for spinning continuous filaments 2 is shown. Preferably and in the embodiment, the spun continuous filament 2 is introduced into a cooling device 11 having a cooling cavity 12. Suitably and in the embodiment, two opposite sides of the cooling chamber 12 are provid...

Abstract

The invention relates to a device for producing a nonwoven fabric made of fibers, wherein at least one spinning device for spinning the fibers and an air-permeable laying conveyor for laying the fibers as a nonwoven fabric web are provided. According to the invention, at least one suction device is provided, by means of which process air can be suctioned through a laying conveyor in a main suctionregion in a fiber placement region. The main suction region is defined below the laying conveyor in the inlet region of the laying conveyor and in the outlet region of the laying conveyor by a suction partition wall, respectively. A vertical distance A between the conveyor-side end of the at least one suction partition wall and the laying conveyor is between 10 mm and 250 mm.

Description

Technical field[0001]The present invention relates to an equipment for manufacturing non-woven fabrics made of fibers, especially thermoplastic fibers, in which at least one spinning device for spinning out fibers and at least one for laying fibers into Non-woven webs or non-woven, air-permeable laying conveyors, especially laying screen belts. In addition, the present invention also relates to a corresponding method for manufacturing such a non-woven fabric from fibers. According to a particularly preferred embodiment of the present invention, the fibers constituting the nonwoven fabric are continuous filaments. Continuous filaments are distinguished from short fibers due to their almost infinite length, which have a much smaller length of, for example, 10 mm to 60 mm. The nonwoven fabric manufactured according to the present invention is preferably composed of such continuous filaments and the nonwoven fabric manufactured using the apparatus of the present invention or the method ...
