Description

one

The invention relates to the technique, the production of nonwoven materials, reinforced by stitching, preferably artificial fur.

A known method of making artificial fur in which the fibrous layer is pre-compacted during transport and fed to the base at a speed exceeding the speed of moving the base. For the implementation of the 3toro method, the installation containing the carding and in the gully Machines, between which the transmitting inclined conveyor is installed, is known. .voloknistogo sealing layer and adjusting its feed rate of the substrate 1 and the dispenser.

The disadvantage of the installation indicated by the methods for its implementation is that the thickness and density of the fibrous layer; applied to the substrate are not uniform, as a result of which groove needles capture a different number of fibers from the fibrous layer. The resulting artificial fur has a coating that is relatively uneven in thickness. The pile height is also not uniform.

The aim of the invention is to obtain artificial fur with predetermined physicomechanical properties.

For this, the fibrous layer directly before its foundation on the base is additionally compacted, and the feed rate of the fibrous layer on the substrate is set to 1 / (2-0.032h) ± 0.3 m / min, depending on the height of the preliminary layer of the base layer. where I / is the layer feed rate; m / min; h - height

compacted layer, mm. In the device for the implementation of the proposed method, the means for pre-charging the thickened fibrous layer and adjusting its feed rate are mounted between the machine and the transfer conveyor and made as a pair of conveyors installed in a vertical plane parallel to one another. A dispenser is mounted behind the inclined transPorter in front of the mortar, which consists of successively mounted movable table and compactor, having a shock absorber, made in the form of a rubber band of triangular cross section.

FIG. 1 shows a device for carrying out the proposed method, side view; in fig. 2 - scheme of the device.

The device comprises means for pre-compaction of the layer and adjustment of its feed rate, made in the form of a pair of vertical conveyors 1, an inclined conveyor 2 and a metering unit with a movable cattle roller 3 and a compactor 4 of the fiber layer, as well as a card 5, into the piercing machine 6, into which the fibrous layer 7, punctured by the groove needles 8, and the base 9 (frame fabric) are directed. In addition, in the patchwork mask 6 there is nap platinum 10. The fibrous layer compactor 4 has a shock absorber, which is a rubber tape 11 of triangular cross section. .

In operation, the fibrous layer 7 lies on a pair of vertical conveyors 1 transporting it to the inclined conveyor 2. The difference in speed between the movement of the pair of vertical conveyors 1 and the inclined conveyor 2 allows pre-compaction of the fibrous layer. Immediately before feeding the fibrous layer onto the base 9, it is additionally compacted, and the feed rate of the fibrous layer 7 to the base 9 is set, depending on the height of the pre-compacted fibrous layer 7, equal to V (2-0,032 h) ± 0.3 m min where V - layer feed rate, m / min;

h is the height of the compacted layer, in mm.

A predetermined number of volbcons are supplied to the hooks of the slot needles 8. By increasing or decreasing the angle of inclination of the movable slide table 3, a predetermined amount of fibers is thrown onto the rubber tape 11. The gap between the end of the compactor 4 of the fibrous layer and the edge of the movable cattle table 3 determines the desired amount into the block supplied by the rubber tape 11 to grab the hooks of the slot needles 8, which capture a certain amount

fibers, dragging them through the base 9 and fastening them on the wrong side.
