Abstract

The invention relates to the textile industry, in particular, to methods for producing woven-in knitted materials, and allows to expand the technological capabilities by creating a bulk material and increasing the range of processed weft yarns. The woven material is made on a double-bottoming machine, the warp threads are laid on the needles of one needle bed and the claws, loops are formed on the needles, and the grips form a shed by horizontal movement to lay the weft yarn and form a woven strip of the desired length, after which The warp threads are transferred with the needles onto the needles of another needle bed, looping them and repeating the process. 4 il.

Description

The invention relates to the textile industry, and in particular to methods for manufacturing woven fabrics.

The purpose of the invention is the expansion of technological capabilities through the creation of bulk material and an increase in the range of processed weft threads.

FIG. Figure 1 shows the layout of the working parts of the machine, on which the method of manufacturing woven knitted material is realized at the time of the formation of the throat; in fig. 2 shows the layout of the working parts of the machine at the time of laying the thread on the hooks of the hooks; in fig. 3 shows the layout of the working parts of the machine at the moment the weft yarn is attached to the fabric edge; in fig. 4 shows the arrangement of the working parts of the machine at the moment of the transfer of the warp threads from the hooks of the sliders, which act as grippers, to the needles of the passive needle bed.

The method of manufacturing woven material is carried out on a special machine containing a shedding mechanism, including two plates 1 and 2, which have grooves and are located at a distance of

one from the other above the needle cases — active 3 and passive 4, the plate 2 being fixed at all, the pushers 5 and 6 of the two positions with marks on two levels: 5a and 56; 6a and 66, the pushers 5 and 6 are located in the slots of the plate 1 and 2, the sliders 7, which function as grippers of the main threads with two hooks 7a and 76, located between the pushers 5 and 6 and mounted so as to move from the grooves of the plate 1 to the slots plates 2 with the help of pushers 5 and back with the help of pushers 6, clamps 8 and 9, by means of which the extreme positions of runners 7 are fixed in the slots of plates 1 to 2. The clamps 8 are mounted on axis 10 and are movable with runners 7. Plate 1 is mounted on axis 11 with the possibility of gate and has an emphasis of 12, and plate 2 is fixed.

The machine contains a mechanism for weft yarns, including platinum 13, installed with the possibility of reciprocating motion in guides and located between plates 1 and 2 and gre (/)

14 and 15 with coarse lugs 16 and 17, in which the warp threads of the warp 18 and 18 are combed 14 mounted under the fixed plate 2 with the possibility of longitudinal shear of the tubular tabs 16 in front of the needles of the active needle bed 3 and in front of the hooks 76 of the sliders 7 through kinematic connections of the comb 15 installed in front of the passive workshop 4 under the movable plate I

The woven material produced by the proposed method contains IS warp threads. and which loops 19 are formed on the needles of the active needle bar 3 and loops 20 on the slimes of the passive needle bar 4 weft bars 21, inserted into the shed 22 and forming 1 warped stripes 23 with warp bases and also additional rows formed and i threads oi. new 181

The method is carried out as follows.

Plate 1 is rotated around axis II to the position (FIG. 2) when tubular lugs 16 of the comb 14 are laid on hooks 76 of all runners 7 of the warp 18 and then the base 18 of the warp 18 is laid under the hooks of the needle box 3, run 1 - kami 7 move up to a horizontal position, and the needles of the active needle bar move i until the formation of loops 1e. In a horizontal position, a portion of the sliders 7 according to the rapport is moved from the left position to the right into the slots of the fixed plate 2 and the laid 7 hooks 7 deflect 7 of the warp 18. The image of the opening 22, F) which, by means of the plug 13 VO1YAG, is an exact thread 21, laid across the entire width of the material, and makes it surf to the edge of the fabric (Fig. 3). At this moment, running at nki 7 is held in place by the latches s and 9, in the left and right position, respectively

After disengagement with clamps 8 and 9, pushbuttons 5 and 6 are moved along horizontal guiding plates 1 and 2 to one end (one facing to another, shed 22, those. Runners 7 with warp threads 18. which are located on the right, move to the left, and the sliders 7 with the warp threads 18, which are located blind, move to the right. The following weft is introduced into the new shed 22, 21 and the arbitrariness of its surf with platinum 1} to the edge of the cloth. At that time the needles of the active needle case 3 hours are lifted up and prevent breakage of the warp 18 because of their processing band repeated as long as the fabric strip formed by the necessary length.

L of the moment when the woven strip of the required length has been completed, of the required length, all the sliders 7 are shifted to the left, and the hooks 76 are pressed against

stop 12 Together with the stop 12, the sliders 7 are moved downward due to the rotation of the plate 1 around the axis 1 1 to the lowest position (Fig. 4). In this position, the sliders 7 are positioned against the needles of the passive needle from the comb 15 side. The hooks 76 of the sliders 7 are retracted from the stop 12 and move the warp 18 from the hooks 76 to the needles of the passive needle bed 4, which make a working movement and form loops 20 of the warp threads 18 Next, the sliders 7 are moved to an inclined position (FIG. 2) by rotating the plate 1, and the process of forming the woven material is repeated.

A method of making woven knitted material, in which woven strips are formed by forming a pharynx from warp threads, laying weft yarns and weaving filaments in the throat at the edge of the material, woven strips are joined by forming loops on the needles, characterized in that expansion of technological capabilities due to the creation of bulk material and an increase in the range of processed weft yarns, the formation of loops is carried out on the needles of a two-phase in a filling machine of warp threads The last needles on one needle bar and hooks of the yarns adopted under the needles, followed by moving the needles down and grips up, form woven strips during the formation of the seams by sequentially moving the grippers in the horizontal direction and laying the yarns into the seams of the yarns. strips by transferring the warp threads from the hooks to the needles of the second needle bed for binding loops to them.
