    1 The invention relates to a text; industrial complex and relates to an open jaw lifting jacquard machine Aiayx with two knife grids moved in opposite directions and passing through each other, as well as controlled from main needles arranged in the transverse direction relative to the knife blade. grids with lifting hooks, which have two main tips, interacting with movable knives, and an upper locking sock that interacts with a fixed knife of the upper shed. Known two-lifting jacquard machine open throat with lifting hooks, made of two shoulders. These hooks have a main spout on the upper end of each side and, besides, on one. side have upper locking spout. The main nozzles are attached to the intersecting knives of both knife grids 1. The known lifting hooks with two M long, spring-loaded sides fall into unwanted vibrations at high revolutions, so that the hooks pointing down from the knife to the bottom shed are free | the non-suspended main nose may engage with the knife of the rising knife grid. In addition, when weaving a thicker thread and with a large number of rapports of the pattern, where a stronger withdrawal of the arcade is required, the long spring sides of the hooks bend, so that the hooks, with their upper stopper nose, are no longer attached to the upper fixed knife. main nose kami. As a consequence, there may be defects in the tissue. The use of double-hooks in a double-jacquard open-throat jacquard machine has an additional disadvantage, the states that the lifting hooks must be pushed by the main needles until both knife grids are crossed so that the lifting hook, which must be lowered to the bottom the pharynx was not seized by the knife above. The time required for squeezing the lifting hooks gives an unfavorable motion ratio in the mechanics of the stem, from which, according to the pattern of feather 012, the main needles are displaced. Since the hooks simultaneously move to the recess of the main needles and move up to the intersection of the knife grids, there is also increased wear of the hooks and main needles. Also known is the jacquard machine, which operates with a single-rod lifting hook that cannot bend even with a strong retraction of the arcade tie 2. However, this known lifting hook rotates around its longitudinal axis, since its two main nozzles are offset from each other by an angle about 90, so that the raised main spout is set transversely to the longitudinal direction of the knife, while the other main spout due to the rotation of the lifting hook around its longitudinal axis turns achivaets a position extending parallel with respect to the blades, and therefore can not be engaged. In these well-known jacquard machines, hooks at very high revolutions can fall into unwanted vibrations that lead to errors in the cap and thus to defects in the fabric. However, the main disadvantage is that the basic sliding of the main nozzles on the blades causes far less wear and tear, especially since the main nozzles must have a cylindrical shape in order to cause as little as possible frictional resistance during rotational movement. This disadvantage has also not been eliminated in a jacquard machine in which the lifting hooks are inserted into the recesses or slots of the knife C 3. The double-jawk open-jaw machine is known to have two installed with the possibility of insertion one-way knife grids, the knives of which consist of holders and two hook plates mounted along each of them, extending along the holders, placed along the knives and controlled from the main needles flat lifting hooks, the largest edge of which is located parallel to the fusing movement of the main needles and each of which has two nozzles
    for interacting with hook plates of movable knives, upper shed tAl
    In a known machine, lifting hooks and knives also do not ensure reliable operation.
    The purpose of the invention is to increase the reliability of work.
    To accomplish this, an open-throat double-lifting jacquard machine containing two knife grids installed with the possibility of moving the knives from one to the other between the knives, while the knives consist of holders and two hook plates mounted on each of them. placed across the blades and controlled from the main needles are flat lifting hooks, the largest face of which is parallel to the direction of movement of the main needles and: each of which has two nozzles for action with hook plates of movable knives, and a stopper nose for interacting with the fixed knife of the upper pharynx, the first of the hook plates of each movable knife in the direction of movement of the main needles have open bottom slots for the passage of lifting hooks, and the second hook plate of each knife has notches placed on trajectories of movement of the lifting hooks for guiding the latter, while the tips of the lifting hooks are arranged parallel to the holder of the movable knives.
    . Nafig 1 shows a jacquard machine, side view; in fig. 2 - knot and lifting hook assembly, side view; in fig. 3 - the same, front view; in fig. 4 shows a second embodiment of hooks and knives, side view; in fig. 5 - the same view.
    An open-jaw double-lift jacquard machine contains two knife grids installed with the possibility of oncoming movement between one another and carrying knives 1, flat lifting hooks 2 placed across knives 1 and controlled from main needles 3. The latter are in contact with head needles 4, which receive movement from the pressure grid 5 and the needle needles 6, interacting with the patterned card 7. Each knife 1 consists of holders 8 and two hook plates 9, 10,
    extending along holders and having control hooks 11, 12 at free ends, bent in opposite directions. Kryuchkova
    the plate 9, the first in the direction of movement of the main needles 3, has open-bottom slots 13 for the passage of the lifting hooks 2. The hook plate 10 has recesses 14 placed on the trajectory of the lifting hooks 2 for guiding the latter.
    Each lifting hook 2 has a rod 15 with a flat rectangular cross section, the largest edge
    which is located parallel to the direction of movement of the main needles 3 At the upper end of the lifting hook 2 at different heights the main nozzles 16 and 17 are located at right angles, which work in conjunction with the control hooks 11 and 12. Near the lower end of the lifting rod 15 hook 2 reinforced upper locking spout 18,
    which works in conjunction with a fixed knife 19 upper throat. At the lower end of the lifting hook 2 hooked arcades cord 20, which is passed through the supporting hook frame 21.
    (The upper end of the lifting hook. 2 with its main spout 16 can, with an appropriate control movement, enter through the groove 13 in
    the hook plate 9, since it is located outside the path of movement of the control hook 11 between the two plates 9 and 10. In addition, the stem 15 of the lifting hook 2 can enter the recesses 14 between the control hooks 12 on the hook plate 10,
    In the middle part, the lifting hooks 2 are missed by the grill rods 22, which are parallel to the main needles 3. In addition, the lattice rods 23 are provided between the lifting hooks 2, which serve as a travel stop for the vertical orientation of the lifting hooks when they are not are controlled by the main needles 3. In the hook plates 9 and 10 (Fig. 4 and 5), control hooks 11 and 12 are stamped, the plates are curved out of the plane sideways and having an incision at the upper end of the U. hooks bent transversely to the longitudinal direction of the main needles 3, These control hooks interact with the main nozzles 16 and 17, which are also stamped from the rod 15 of the lifting hook 2 and curved transversely to the longitudinal direction of the main needles 3. Since the distance between the control needles the hooks 11 and the hook plate 9 are larger than half the width of the rod 15 of the lifting hook 2, then the main spout 16 can extend inwards onto the control hook 11 when the associated lifting hook 2 does not have to be moved from its polo Yeni lower pharynx. The function of the jacquard machine for open throat, as well as the use of the mutual arrangement of knives and lifting hooks, is shown in FIG. 1 and 2 In order to facilitate the description of the operation, the various positions of the lifting hooks are in order designated by the letters A, B, C D, and E. The lifting hooks 2 are controlled in a known manner from the pattern card 7 through the consisting of the needle needles 6 of the head needles 4 and main needles 3 needle mechanism with a clamping grid 5, moving in the direction of intersecting arrows in the drawing. For the position A of the lifting hook 2, the relative shock is attached to it and the a la 6 finds the hole in the patterned carriage 7, so that the head needle 4 is not pressed by the pressure grid 5 and therefore remains in a resting position together with the main needle 3 related to it. The lifting hook 2 is not pressed in this way, and therefore is gripped by the lower knife 1 and pulled from the position of the lower pharynx upward to the upper pharyngeal position, which corresponds to the position B. When lowering the knife 1, on which the lifting hook 2 is suspended 18 stops at knife 19, upper shed. In this position it can remain in the upper pharynx. In position C, the needle 6 of the lifting hook 2, which is in the upper throat position, did not find a hole in the patterned card 7, so that the lifting hook 2 is pressed by the pressure grid 5 through the front needle mechanism and thus the upper locking sock 18 is squeezed out of the knife area 19 upper throat. The lifting hook 2 can then be moved from position C with the help of the knife 1 to the lower shed. In position D, the lifting hook 8 is directed by the knife 1 to the position of the upper os. Since the patterned relating to it, the stypal needle 6 did not find the holes in the patterned map 7, the lifting hook 2 by the pressure grid 5 is pressed through the front needle mechanism. As a consequence, the upper locking sock 18 remains free from the upper shed knife 19, so that the lifting hook 8 immediately goes back into the lower shed, which corresponds to position A. In position E, the lifting hook 2 is in the lower shed position and stopped on the supporting hook frame 21 Relevant to it, the shovel needle 6 did not find the holes in the patterned map 7, so that the lifting hook 2 by the pressure grid 5 is pressed through the front needle mechanism. As a result, the upper end of the lifting hook shaft 15 is rotated so that the main spout 16, through the groove 13, enters the hook plate 10 and thus gets out of engagement with the control hook 11 when the knife 11 moves from the lower shed to the upper shed. The lifting hook 2 in position E remains in this way in the development: it is open.
