PREFERRED EMBODIMENTS OF THE INVENTION

(10) As can be seen in the attached drawings, the knitted item consists of knitting threads 9 and front and back weft threads 10, 11 forming courses 30 and wales 29, as well as front plush threads 14 and back plush threads 12. The knitting threads 9 form loops in which the front and back weft threads 10, 11 are applied to obtain a knitted base. The rear plush threads 12 are bonded between two adjacent wales 29 to form a rear plush surface, and the front plush threads 14 are knitted in two consecutive courses 30 of two adjacent wales 29. The front weft threads 10 are applied at every four wales 29 for one course 30, and the rear weft threads 11 are applied at every four wales 29 for the next course 30. The rear plush threads 12 are cut at given steps (a) to form a plush pile on the back surface of the item.

(11) The machine for the production of a plush pile knitted product consists of a housing 26 wherein a horizontal support rail 2 is mounted, on which slots 24 are formed, in which knitting needles 1 are placed. The knitting needle 1 consists of a body with a thinner part 19, at the front end of which a tongue 18 is mounted in a widening through a hinge 17, and after the widening a hub 21 is formed, which ends with a hook 20 having a tip 15, under which a pushing surface 16 is formed. Front plush plates 7 and rear plush plates 8 are fixed on the housing 26 and between them are located front application needles 4 guiding the front weft threads 10 and rear application needles 5 guiding the rear weft threads 11 to form courses 30. Behind the rear plush plates 8 are located application needles 6 guiding the rear plush threads 12. To the housing 26, on the side of the front plush plates 7, are placed first application needles 3 guiding the knitting threads 9 to form wales 29 and second application needles 13 guiding the front plush threads 14. The front and rear application needles 4 and 5 lie in a plane perpendicular to the knitting needles 1. In the lower part of the housing 26 is mounted a main drive 28, the shaft of which is connected to the knitting needles 1 by gears. Along the entire length of the machine, multiple closing safety plates 23 are mounted on the housing 26 above the knitting needles 1, which can move in the vertical direction and ensure the closing of the knitting needles 1. On the housing 26 are mounted push plates 22 designed to press the front and rear weft threads 10 and 11. At the lower end of each of the rear plush plates 8 is mounted a cutting disc 27 for cutting the rear plush threads 12 on the knitted course 30. The knitting threads 9, the front plush threads 14, the front weft threads 10, the rear weft threads 11, as well as the rear plush threads 12 are fed in by means of separate step motors 25.

APPLICATION OF THE INVENTION

(12) Upon starting the drive 28, the step motors 25 are switched on and the knitting cycle starts. The knitting needles 1 perform a reciprocating movement back and forth. In the forward direction, the knitting needles 1 go between the rear plush plates 8 and the front plush plates 7 and above the rear plush threads 12 applied by the application needles 6 and the front and back weft threads 10, 11 applied by the front and rear application needles 4 and 5. Upon reaching front dead center, the application needles 3 guiding the knitting threads 9 form a loop wherein the front weft threads 10 are applied to obtain a knitted base. The second application needles 13 apply around the front plush plates 7 front plush threads 14 to obtain a plush surface. Thus, a knitted course 30 is obtained. To form a row, the first application needles 3 perform two movements: left or right shift and up or down movement. The same movements are performed by the second application needles 13, which apply the front plush threads 14 left to right in the knitting needles 1 for the course shown while for the next course the second application needles 13 apply them right to left. Each application needle 13 applies in two consecutive courses the front plush threads 14 on two adjacent knitting needles 1 and form a front plush surface using the front plush plates 7. When moving backwards, the closing safety plates 23 move downwards and close the tongues 18 of the knitting needles 1 before they enter the knitting zone. Upon reaching a third dead center, the knitting needles 1 are released from the old loops with the push plates 22 moving down and pressing on the front 10 and rear weft threads 11 to move them under the knitting needles 1. Thus, the finished course is removed from the needles. Then, the knitting needles 1 move forward and pass above the applied front 10 and rear weft threads 11 to form the next course 30. The back plush threads 12 of the back plush surface are cut off by cutting discs 27, which rotate from the back loop formed around the rear fixed plush plate 8 when the knitted plush item is pulled out of the knitting zone.
