A manufacturing method for a voluminous fabric with a smooth surface, a high compression resistance, a small residual deformation after repeated compression and with a minimum thickness of 2 mm consists in that a strip of planary fabric, produced by bonding of a fibrous web, composed of perpendicular or random oriented fibres in its whole thickness, is split by cutting, resulting in at least two layers of planary voluminous fabric products with a smooth surface, parallel to the plane of the planary fabric strip. A device for manufacturing voluminous fabrics with a smooth surface consists of a pair of conveyors (1 and 2) whose vertical and horizontal position to each other is controllable, and also of at least one endless steel blade strip (3) with a cutting edge, guided in between the outlet of the conveyors (1 and 2), a system of guide rollers (13) and supported by a guide slat (4), and further of at least two winding devices (6 and 8). The tangents to the roller of the winding devices (6 and 8) pass through the outlet of the feeding conveyors (1 and 2) at an angle of 15 to 45 DEG . The steel blade strips with the cutting edges can be arranged in cascade perpendicular to the plane of the guide roller system (13), their distance from each other and from the feeding conveyors (1 and 2) being controllable. |
