Embodiment Construction

[0028] exist figure 1 with 2 A first embodiment is shown schematically in several views in . figure 1 A longitudinal sectional view of this embodiment is shown, figure 2 A top view is shown. The following description applies to both figures, as long as reference is not explicitly made to a certain figure.

[0029] A first embodiment of the device according to the invention for producing fiber products by depositing melt-spun fibers has an air-permeable deposit belt 6 which is guided over a plurality of belt rollers 10.1 and 10.2. The deposit belt 6 is only partially shown and is generally designed as an endless belt and is guided by one or more driven belt rollers.

[0030] On the upper side of the deposit belt 6 there is a spinning device 1 comprising a spinning beam 2 arranged at a distance from the deposit belt 6 . The spin beam 2 has on its underside a nozzle arrangement 3 which in this case serves to melt-blow the fibers from the spinning nozzle and which has two ai...

Abstract

A device is described for producing a fiber product by laying down melt-spun fibers onto a laydown belt. A spinning device is associated with a top side of the laydown belt and a suction-extraction device is associated with the bottom side. A vacuum device has a movable suction chamber which interacts with the spinning device in order to lay down the fibers on the laydown belt. To generate a uniform suction flow in every position of the suction chamber, the suction chamber is formed from a stationary bottom box and a movable top box which are coupled to one another in a pressure-tight manner.

Description

technical field [0001] The invention relates to an apparatus for producing fiber products by depositing melt-spun fibers according to the preamble of claim 1 . Background technique [0002] Such a device for producing fiber products by depositing melt-spun fibers onto a deposit belt is known, for example, from WO 2010 / 054943 A1. [0003] When laying melt-spun fibers on the laying belt, a suction device is provided on the underside of the laying belt, so as to receive and discharge the blowing wind generated during laying on the one hand, and to influence the blown air used to form the fiber product on the other hand. The laying of fibers on the surface of the laying belt. It is necessary here to generate a substantially uniform underpressure in the deposition area on the underside of the deposition belt by means of a suction device, in order not to produce inhomogeneities during the deposition of the fibers and the reception of the blowing air. For this purpose, the known ...
