Description

1 The invention relates to the textile industry and can be used for making a jacquard machine for a loom by making a ticker board. A device for assembling a jacquard machine for a loom, containing a mounting plate and means mounted on it for orienting the bars of a casket board in the plane of the plate at an angle to its longitudinal axis and pressing ponds, is known. A disadvantage of this device is the arrangement of orienting elements on the mounting plate at unchanged distances x. Such a design leads to the need to have sets or with orienting elements for each) of the standard size of the pool board. As a result, a significant production area is required for: fanning of all assembly bases of various sizes. In addition, the manufacture of these bases with orienting elements leads to unnecessary material and labor costs. The aim of the invention is the expansion of technological capabilities. This goal is achieved in that the tool for assembling a jacquard machine for a loom, containing a mounting plate and mounted on it for orienting the bars of the pool in the plane of the plate at an angle to its longitudinal axis and the pressure of bars, is made in In this way, a set of contact bars between each other and in particular longitudinal grooves for locating rods, while CMOHTfr bars are pivotally pivotally rotated in the slab plane. On . 1 shows a pool, plan view; in fig. 2 - then Mte, side view; Fig. 3 shows a device for accommodating one row of rods; in fig. 4 shows section A-A in FIG. 3; in fig. 5 is a section BB in FIG. 3; FIG. 6 shows the position of the two devices after the assembly of the pool board. The pool is located one after the other two rows of bars 1 and 2 crossing at an angle (figure 1), the ends of which are fixed in labels 3 (figure 2). Skircles 4 are installed along the board torn bars. Rods 1 and 2 О6ОО2 open up holes 5 of the pool board, arranged in a checkerboard pattern for passing the arc of cords (not pjazz).: A device for assembling the board board of a jacquard machine includes for each row of bars 1 and 2 installation plate b (Fig. 3), on which the tool for orienting the rods is installed, comprising a set of adjacent 7 bars 7 that can be rotated, for example, on individual axes 8 in the plane of the plate 6 at a predetermined angle for different sizes of pool boards. The axes 8 of the starts 7 are placed in the longitudinal 9 of the plate 6. The longitudinal grooves of the mounting plate can be made either in its middle part (Fig. 3) or on the sides of the base (not shown). In each of the bars 7 there is a groove S for placing bars 1 or 2, with the longitudinal axis of each groove intersecting the longitudinal axis of the slab. A clamp 11 is located on both sides of the set of bars (fig. 3), which is made, for example, in the form of squares, allowing the bars to be fixed at a given angle. The squares are fastened along the edges of the slab b by means of a bolted joint installed in the groove 9 of the slab. In another embodiment of the bars 7 without axes 8, the slab b is additionally equipped with side restraints (not shown) mounted on the longitudinal sides of the slab, while the ply shrubs are located on the slab between the angle; E 11 and the side restraints. One use of the apparatus for assembling the jacquard machine pool board is as follows. Before placing bars 1 and 2 of the pool board on two plates b with sets of bars 7, the latter are installed perpendicularly to the longitudinal axis of plate b, then the entire set of adjoining bars with bars 1 and 2 are placed at a given angle c. according to the angle of the bars crossing and fix the bars with the bars with the help of squares 11. After that, one or both plates are rotated around the longitudinal axis (s), and both plates are joined (fig.b) so that the bars 1 of the same row of the pool board cross with rods 2 other p yes.

The angle at which the orienting elements are installed (Fig. 3) is determined by the calculation using the formula

where oL is the angle of inclination of the bar to the longitudinal axis of the board;

b is the thickness of the wall of the bar, which is equal to half the diameter of the hole of the pool board; (C is the diameter of the bars of the swimming pool;

t is the pitch of the holes in the longitudinal row of the pool board (the holes are set in a staggered order). In the above formula, the wall thickness of the bar b and the diameter of the rods in can be taken to be constant. The size of the hole pitch -fc in the longitudinal row of the basin board is determined by a preliminary calculation according to the method

known jacquard weaving, depending on the fabric to be fabricated, after the connection of the installation bases with the rods placed on them is fixed (Fig.6) the ends of the bars 1 and 2 and the bones 4, for example, in the patch as 3.

Swimming pool board made with

using the proposed device, they are installed together with a jacquard machine on a weaving machine.

The use of the invention will allow

reduce by at least 5 times the number of installation plates with orienting elements required for the production of kaosay boards. This is achieved by saving production space, as well as material and labor costs for the manufacture of mounting plates with orienting elements.
