Abstract

Tools and methods for making low-density, high-strength, non-woven fabrics from membranes consisting of at least about 5 percent of the two component fibers and The fabric is formed that way in which the membrane is grafted. superimposed on the first conveyor belt The sheer sieve belt is grafted onto the membrane and the membrane and belt are overrun in the line path. The bend is made to draw closer to the heating path when doing it. Provides low melting point components of fused welding fibers with heat into the fibers of the membrane

Claims (4)

With at least 5 percent thermoplastic fibers on the first long conveyor belt (b) over the long conveyor belt. A second, onto the said membrane to create two conveyor belts, with the membrane being sandwiched between the first and second long conveyors (c) at least one such conveyor. Will have a transparent grid structure, formed by positioning The grille is attached to each other in order to indicate the space between the body. (D) the guide of the two belts To move in a continuous drawn path around a section of First and second hot rollers Indented Each other And stay away from each other with enough distance to avoid The compression force between the first and the second hot rollers. The periphery of the first and second hot rollers. Together to achieve that part of the path to Where the articulation of the two belts travels out of contact with First hot roller And the second one as The heating begins on the first side of the membrane in While the two such belts were applied. Goes around the first hot roller and as a result melts The least Thermoplastic fiber attached to the body The grate is pressed against the fibers adjacent to one side of it. And after that the second side of the membrane is heated. While the two such belts Was brought around that roller. The second hot, and as a result, melts at least the strands. The thermoplastic filament is attached to the grate to the wire. The web next to its second side Cause a membrane that has The defined area is a patterned surface, associated with the clear area between the aforementioned grilles that maintain the upper layer. The high and low density of the membrane which is surrounded by And (e) cooling the two plates after they move around the hot roller. One and the second In order to reduce the heat of the fibers in The membranes are between the first and second long conveyors. 2. Method as mentioned in claim 1, where the process This is done by placing the two belt pads around the ball. Third hot roller and fourth hot roller 3. Method as mentioned in claim 2, where the third hot roller is The second one is across the horizontal and vertical crossbars from the roller. The one said The third roller was placed. Above the first roller vertically And the fourth roller It is placed above the second roller vertically, with a few dovetails. Being led along a winding path Where one side of the membrane is heated By the first and third rollers as mentioned and the second The pulp was heated by the second and fourth rollers as mentioned. 4. Method as mentioned in claim 1 where the conveyor Other than that, is placed on the conveyor belt that is Such a transparent grid to create a belt splice that is Lead through the aforementioned path. 5. Method as mentioned in claim 1, where the sieve Of the first conveyor belt is placed in line with the mesh Of the second conveyor While the two belt splice sound It moves along the said path. 6. Method as mentioned in claim 5, where the grid Of the first conveyor belt is placed in line with the mesh Of the second conveyor While the two belt splice sound It moves along the aforementioned path. 7. Method as mentioned in the first claim where the procedure The cooling was done by making the two mesh belts sound. It moves through the coolers. 8. A tool for forming non-woven fabrics consists of Thermoplastic fiber The machine consists of (a) a frame, (b) the first and second hot rollers that are rotated. The ball is placed at a distance of sufficient distance from each other to avoid Avoid compression force between the aforementioned first and second rollers. (C) The first and second long conveyor medium. (D) the second long conveyor center was installed on the frame as To move along that path around the roller part. The first and the second hot That caught in the middle The first such belt (e) at least one of the In the middle of the conveyor belt there is a structure made of a transparent sieve. By placing the grille next to each other to determine the area Air gap between the specified grates (f) Medium for trapping Pulp Minimal composite fibers, 5% of thermoplastic fibers are placed onto the first belt medium so that In the middle of the belt, the first and the second were formed sheets. Splice two belts with the membrane between them. Such two splice plates are moved in such a path. It is said continuously around the part of the hot roller that One such for the heat starts with one side of Such membranes And fused, at least the thermoplastic fibers adjacent to The grate is attached to the fiber adjacent to the first side. Of it and move around the second hot roller part. Said for heating the second side of the membrane and At least fused the thermoplastic fibers attached to the body. Such a sieve with fibers that are attached to its second side to As a membrane with a defined area as a machined surface, related to the clear space between the sieves, which Maintains a high, low density upper layer of the membrane which is surrounded With the area that has been melted along the grid (g) the outer surface of the ball. The first and the second hot roll together to Resulting in the part of the path where the two belts It moves away from contact with hot rollers. The first and the aforementioned second and (h) the medium for lowering the aforementioned slats after it has moved around. The first and second hot rollers thereof to reduce Heat to fibers in membranes that are sandwiched between conveyor belts. The first and second long. 9. Apparatus as mentioned in Proposition 4, where such coolant consists of at least the child. One 0. The tool, as mentioned in claim 4, where the third and fourth hot rollers are attached to the frame. Said in a manner indented to each other The third roller and the The fourth was placed far enough away from each other. Avoid compression force between the first and second rollers as mentioned 1. 1. The tool as mentioned in claim 1, where the third is being rolled, is placed over the first roller. And the fourth roller was placed above The second such vertical roller 1. 2. The tool as mentioned in claim 4, where another long conveyor medium is attached to the frame. Said in order to move along the said path in a timely manner with On the conveyor medium with such a transparent grid structure 1 3. The tool as mentioned in the 4th claim, where the first and second rubber conveying medium have The structure is a transparent grid, determined by the grid attached to it 1. 4. The tool as mentioned in claim 13, where the sieve of the first long conveyor belt medium is as follows. It was arranged the cat to the grid of the medium, the long conveyor belt. The second, while the middle of the first long conveyor belt And the second one follows that path (14 claims, 5 pages, 6 photos).
