Abstract

The invention can be used in the industry of insulating building materials for forming a fibrous web. The goal is to improve the quality of products by obtaining a canvas of the same total and density. The device comprises means 1 for forming a fiber, a fiber deposition chamber 2, a receiving 3 and an impregnating 4 conveyors, a device for forming the edges of the canvas, consisting of snails 5 for Edge backing and sealing plates 6, placed behind the scrolls above the edges of the exposed canvas. The deposition chamber is made in terms of trapezoidal shape. This ensures that a fibrous web is obtained at the outlet of the deposition chamber in cross section, also in the form of a trapezium, regardless of the number of working fiber forming means. The trapezoidal section of a fibrous canvas allows, after turning its edges, to obtain a canvas of uniform thickness over its entire width. 1 hp f-ly, 3 ill. i (L s

The invention can be used: in the industry of insulating building materials to form a fibrous canvas by melt blown.

The purpose of the invention is povtachenie ka1

the quality of the product by obtaining a canvas of the same thickness and density.

Ia figure 1 schematically shows the device, a general view; figure 2 - the same plan; FIG. 3 shows a fibrous web at the exit of the deposition fiber chamber, a cross section.

sections and so on, which ensures the operability of the device when disconnecting any of the fiber forming means. C, the receiving conveyor grids, the web is fed between two edge shaping devices — snails 5, mounted along the edges of the canvas, in which the edges of the canvas are folded and the canvas extends at a predetermined width with the edges tucked to the same thickness as the material itself. The passage under the sealing plates 6, tucked edges of the canvas

Claims (2)

Claims 1. A device for forming a device for forming the fibers is compacted and the canvas enters the net canvas. contains. means 1 ku impregnating conveyor. for the formation of a fiber, a shaft-type fiber deposition chamber 2, a receiving 3 and an impregnating 4 conveyors, devices for forming edges,; 20 having snails 5 for turning the edges of the canvas and sealing plates 6 installed by snails above the edges of the folded canvas. A device for forming a fibrous web works as follows. The fibers of the fiber forming means 1 are blown onto the mesh of the receiving conveyor 3, the fiber width being determined by the center line of the trapezoidal trapezoidal fiber chamber 2 for forming the fiber, the shaft-type fiber deposition chamber, 25 for shaping the edges and the impregnating conveyor, characterized in that, in order to improve the quality of the articles by obtaining a canvas of the same thickness and density, the chamber 30, the fiber deposition is made in terms of trapezoidal shape with a large base at the exit of the receiving conveyor. precipitation. and the cross section of the fibrous web 7 at the exit of the deposition chamber has a trapezoid shape. The next layer of the similar layer is laid on the first fiber layer. Claim 1. The device for forming is compacted and the canvas is fed to the net of the impregnating conveyor. 15 are compacted and the canvas enters the net of the impregnating conveyor. 20 shaft for fiber formation, shaft-type fiber deposition chamber with a receiving conveyor 25 for shaping the edges and the impregnating conveyor, characterized in that, in order to improve the quality of the articles by obtaining a canvas of the same thickness and density, the chamber 30, the fiber deposition is made in terms of trapezoidal shape with a large base at the exit of the receiving conveyor. 2. A device according to claim 1, characterized in that each of the devices for forming the edges is made in the form of a cochlea and a sealing plate mounted behind it. 35
