Description

The invention relates to textile equipment, in particular, to in-weaving looms, and can be used in the textile industry for the production of woven fabrics and tapes for household and technical purposes.

The aim of the invention is to improve the quality of the fabric produced.

Fig. 1 shows a kinematic scheme in a loom; figure 2 - the position of the rod with the heel and in the needle hall in the throat; on fig.Z - baby machine, cross section; in FIG. A — installation of a rod with a wire on a fender bar; on fig.Z - installation in the needle needle.

In the loom-weaving machine (Fig. 1) contains navoy 1 and 2 with yarns of warp 3 and weft A, a mechanism 5 for yawning with remixes 6 and 7, a mechanism 8 for fitting weft threads to the edge, for example, a batten 8, with reed 9 The shedding mechanism 5 and the batane 8 are kinematically connected with the main shaft 10 of the machine. Rotary niteclayers 11, flags of which are filled with weft threads 4, pass their rods between the teeth 12 of the Byrd 9 and are placed between the threads of the warp 3 with a certain step along the width of the machine. The core of each thread guide 11 is connected at one end by a sleeve coupling 13 to a corresponding output axis 14 of a rack-and-pinion gearbox 15 of their rotation mechanism mounted on the guide bar 16, which is mounted between the rock 17 and shims 6 and 7 under the thread of the base 3. Guide The beam 16 with the turning mechanism is suspended from the machine body with the possibility of rotation and vertical movement with subsequent rigid fastening to the body. The other end of the thread-laying rod 11 is installed in the hole of the support bar 18 which is mounted under the bar 19 with the tongue W with needles 20 in the hall mechanism 21. The bar 19 is mounted for movement on the guides 22, which are fixed to the machine body. Plank 19 receives movement along the warp yarns 3 from the drive into the hall mechanism 21, which is kinematically connected with the main shaft of the machine 10 (not shown). On the chest 23 of the machine is installed the fender bar 24.

The machine is provided with a means to prevent the needle tabs from being randomly closed. The tool contains, by the number of needles, 20 rods 25, which are placed in the shedding zone and pass between the teeth 12 of the reed 9. Each rod 25 is fastened with a clamp 26 and screws 27 and 28 secured

on the strap 29, which is located above the strap 19 with the needles 20 and fixed to the machine body outside the zone of movement of the reel 9. Each rod 25 is provided with a finger b, which is located

parallel to the needle movement path so that during a possible arbitrary rotation of the needle from the needle when closing from the moment the loop is removed from the button to the moment the weft yarn 4 is captured, it is located on the needle from the needle 20 and interacts with it. In this case, the tongue from the needle 20 will be held by the heel b c, the cord 25 against any closing. Adjustment of such an interaction between b and the tongue is achieved by displacing the rod 25 in the clamp 26 and the corresponding fastening of the clamp 26 on the strip 29.

The baffle 24 (FIG. 3) is provided with vertical grooves d for the passage of the thread-laying rods 11 to the support bar 18 with holes for mounting the ends of the thread-spade. Support

the strap 18 with screws 30 is attached to the chest 23 of the machine. To adjust the position of the support bar 18 in height and angle of inclination, a gasket 31 is used.

In the manufacture of rolled-up fabric with a ribbed edge, such as ribbons, it is advisable to use a breaker bar 24, which is always located outside the reed-moving zone, and the rods 25 are not installed over the needles 20. , as in the manufacture of solid cloth, and to the side of the needles from the side

tapes where edges are wound. AT

In this case, a better overview is provided, the convenience of refilling the machine, since the rods with pts are located below the material edge below the lower branch of the pharynx and do not overlap the zone of material formation. Since the pin 25 with the pin b is installed on the side of the needle 20, to ensure the interaction of the tongue with the needle from the pin b in 313

The needle should be set at an angle of / 3 to the bar 19 in the hall mechanism (FIG. D and 5). The angle P is between 45-60. The installation angle P in the needle needle 20 is provided by fastening the needle to the bar by means of a clamp, which is provided with an inclined groove at an angle p to the bar 19,

To remove the finished material from the formation zone, the machine is equipped with a marketable roller (Fig. 1).

In the weaving and loom works as follows.

The formation of a zano-woven material is carried out by the joint action of the shedding mechanism 5 with heels 6 and 7, the batten mechanism 8 with the reed 9, the thread layers 11 weft threads and the tongue needles 20 into the entrance mechanism 21. In the initial position the reed 9 is near the edge of the material, and the flags and laying lines 11 are arranged vertically. At each turn of the main shaft 10 of the machine, the shedding mechanism 5 forms a pharynx of warp threads 3, and in the needle needles 20 are inserted into the pharynx by moving the bar 19, while the thread guides 11 begin to rotate from the moment when the reed 9 moves from the edge of the material, will be located behind the flags q, Flags and thread grids 11 lay the weft threads 4 under the hooks of the needles 20, which are then removed from the pharynx and fasten the hinge bars. When wound stitch columns, the strings b of the rods 26 interact with the tabs — from the needles 20 from the moment the loop is dropped from the tongue to the moment it snaps.

cotton wool crochet needle weft yarn. This ensures that there is no arbitrary closing of the tabs. Then, after looping the stitch posts, the shedding mechanism closes the throat, forming between the warp yarns 3 and the weft yarns 4 weaving in some parts of the web, which are interconnected by looping

columns. By the action of Byrd 9, the weft threads are nailed to the edge of the material, while the hooks of the needles 20 removed from the pharynx by the edge of the material of the needles 20 hold loops of the weft threads. After the surf

a new pharynx is formed and the process is repeated. The finished material is withdrawn from the formation zone and wound onto a product roll.
