На каретке 4 имеются направляющие 8, по которым в направлении основных нитей 3 ковра возвратно-поступательно перемещается основание 9 с узловязальными механизмами 10, каждый из которых выполнен из двух вилок,' несущих направитель И ворсовой нити. На кареткахThe device contains two rollers 1 and 2, bearing the main threads 3 of the carpet and the carriage 4 and 5, installed on the guides 6 and 7, respectively placed with the front and wrong side of the main: threads 3. On the carriage 4 there are guides 8, along which In the direction of the main threads 3 of the carpet, the base 9 with knotting mechanisms 10 reciprocatingly moves, each of which is made of two forks, bearing the guide And the pile thread. On carriages

8 и 5 установлены ограничители поперечного перемещения основных нитей 3, количество которых соответствует числу узловязальных механизмов 10. Каждый ограничитель поперечного перемещения основных нитей 3 включает две скобы 12 и 13 с горизонтальными ветвями. Скоба 13 посредством основания 9 и пружин 14 соединена с даправителем 11 ворсовой йити, а скобы 12 жестко закреплена на направляющих 15 перед средством 16 для направления ворсовых нитей в направитель 1I. При этом скобы 12 и 13 каждого· ограничителя установлены с возможностью контактировавания ветвями. Необходимое положение скобы 12 обеспечивается стопором 17. Для этого перед работой скоба 12 подводится по направляющим 15 до соприкосновения с основными нитями 3 ковра и в этом положении фиксируется.8 and 5, limiters of lateral movement of the main threads 3 are installed, the number of which corresponds to the number of knotting mechanisms 10. Each limiter of lateral movement of the main threads 3 includes two brackets 12 and 13 with horizontal branches. The bracket 13 by means of the base 9 and the springs 14 is connected to the pile yarn guide 11, and the brackets 12 are rigidly fixed to the guides 15 in front of the means 16 for guiding the pile threads into the guide 1I. In this case, the brackets 12 and 13 of each limiter are installed with the possibility of contacting by branches. The necessary position of the bracket 12 is provided by the stopper 17. For this, before work, the bracket 12 is brought along the guides 15 until it contacts the main threads 3 of the carpet and is fixed in this position.

Устройство работает следующим образом.The device operates as follows.

При движении узловязального механизма 10 в направлении основных нитей 3 основание 9 перемещает скобу 13 в том же направлении до контактирования ее горизонтальных ветвей с ветвями скобы 12. Между ветвями скоб 12 и 13 расположены основные нити^8 ковра, После контактирования ветвей скоб 12 и 13 перемещение скобы 13 прекращается. Основание 9 φ узловязальными механизмами 10, продолжая свое движение, сжимает основные нити 3 ковра между ветвями скоб 12 и 13 за счет сжатия пружин 14. После прохода заостренного конца нитенаправителя 1I через основные нити 3 последние будучи натянутыми между валиками 1 и 2 и зажатыми между ветвями скоб 12 и 13, зацерживают движение подпружиненного нитенаправителя 11. Зажатие основных нитей 3 между ветвями скоб 12 и 13 ограничивает прогиб первых, что дает возможность уменьшить ход узловязальных механизмов 10. При дальнейшем перемещении узловязального механизма 10 концы ворсовой нити выходят из его подпру6018 4 жиненных вилок и располагаются над. глазком .'нитенаправителя 11. В этом положении через средство 16 для направления ворсовых нитей подается под 5 давлением воздух, который переносит свободные концы ворсовой нити через глазок нитенаправителя 11. При обратном движении узловязального механизма 10 нитенаправитель 11 переносит свободные концы ворсовой нити через пространство между основными нитями 3. Ветви скобы 13 под действием пружин 14 продолжают некоторое время контактировать с ветвями скобы 12, ₎₅ затем, когда пружины 14 освободятся, подача воздуха прекращается, а скоба 12 вместе с основанием 9 занимает исходное положение.When the knitting mechanism 10 moves in the direction of the main threads 3, the base 9 moves the bracket 13 in the same direction until its horizontal branches contact the branches of the staple 12. Between the branches of the staples 12 and 13 are the main threads ^ 8 of the carpet. After contacting the branches of the staples 12 and 13 move staples 13 stops. The base 9 φ with knotting mechanisms 10, while continuing to move, compresses the main threads 3 of the carpet between the branches of the brackets 12 and 13 by compressing the springs 14. After the pointed end of the thread guide 1I passes through the main threads 3, the latter are stretched between the rollers 1 and 2 and sandwiched between the branches staples 12 and 13, inhibit the movement of the spring-loaded thread guide 11. Clamping the main threads 3 between the branches of the staples 12 and 13 limits the deflection of the first, which makes it possible to reduce the progress of knotting mechanisms 10. With further movement of the knotter of mechanism 10, the ends of the pile thread come out of its spring 6018 4 forks and are located above. eye. 'of the guide 11. In this position, air is supplied under pressure 5 through the means 16 for guiding the pile threads, which transfers the free ends of the pile thread through the eye of the thread guide 11. When the knotter 10 moves backward, the thread guide 11 transfers the free ends of the pile thread through the space between the main threads 3. The branches of the bracket 13 under the action of the springs 14 continue to contact for some time with the branches of the bracket 12, _{) 5} then, when the springs 14 are released, the air supply is stopped, and the bracket 12 together with Warp 9 occupies its original position.

Далее цикл повторяется.Next, the cycle repeats.

₂₀ Устройство позволяет повысить качество и производительность ковровых изделий за счет ограничителей поперечного перемещения основных нитей, не допускающих их большого удлинения ₂₅ и прогибов. ₂₀ The device allows to improve the quality and productivity of carpet products due to the limiters of the transverse movement of the main threads, not allowing their large elongation ₂₅ and deflections.
