Description

Known fringe machines are equipped with mechanisms for forming from the main and weft threads the edges of the fringe and from weft threads - twisted brushes, using fixed rods fixed in the horizontal direction with weft yarns of weft threads and hooks for gripping, pulling and twisting the weft threads when forming brushes rotated by a gear drive and moved in a vertical direction.

The described fringe machine will enable the development of the edge of the fringe with a different pattern of weft threads. For this purpose, the edge forming mechanism is made in the form of a fixed comb under the yarn feeders with a needle needle for the warp threads and another comb with a tongue needle, shuffled horizontally to the comb with the needle needle through the cams on the upper camshaft. A jacquard apparatus including a prism with holes, a layer of perforated cardboard and turned by a ratchet drive was used for selective mixing of slats with yarn feeders. The jacquard apparatus is mounted at both ends of the rail on a lever driven by a crank, inserted by means of a gear transmission from the upper camshaft. average cam shaft. To drive the gear drive of the hooks on the carriage, rails are mounted that are moved by means of double-arm levers, rotated by cams attached to the lower camshafts. In order to remove the hooks of the twisted tassels of the fringe, the mechanism of the formation of the fringe is equipped with removable hooks mounted on the fixed bar and set in motion by the fingers of datum No. 118393-2 -

ginennogo slat, moved by a lever rotated Cam mounted on the lower camshaft.

FIG. 1 shows a fringe machine, front view; in fig. 2- the same, side view; in fig. 3 is the same, top view; in fig. 4 shows the location of the yarn feeders and needles for working the edge of the fringe in two projections; in fig. 5-gear drive hooks on the carriage for twisting the fringe; in fig. 6- installation of removable hooks.

From the electric motor / through gears 2 and 5, and the belt drive 4 receives rotation of the main shaft 5 of the machine, which via bevel gears 5 and 7 transmits rotation to the upper cam shaft 8. The latter moves the comb 10 with tongue knitting needles 11 in the horizontal direction with the help of cams 9 towards the fixed comb 12 with needle needles 13 through which warp threads pass from the coils M located in the lower part of the machine.

Combs 10 and 12 are located under the yarn feeders 15, through which the weft threads from the coils 16 are passed. carrying perforated cardboard and pivoted ratchet actuator 19.

The jacquard apparatus is mounted at both ends of the rail 17 on the lever 20, driven by crank 21 by means of gears 22 and 23 on one side and gears 24 and 25 from the upper camshaft on the other side.

Hooks 26 for lifting and twisting the fringe are mounted on the carriage 27, moving in the vertical direction by means of toothed rails 28, kinematically connected with the gears system 29; the latter are driven by the toothed sector 30, the lever of which is actuated by the cam 31 locked on the middle cam shaft 32.

In the carriage 27 there is mounted a mechanism for twisting the fringe threads, consisting of a system of gears 33, driven by a gear rack 34, which is agitated by double shoulders 35, rotated by cams 36 fixed to the lower camshafts 37. Camshafts 37 are driven by the upper camshaft 8 by means of chain gears 38 to bevel gears 39. The rake 34 sequentially rotates the gears 33; In the axis of the last gear 40 a hook 26 is installed, which, rotating, twists the brush of the fringe.

The detached hooks 41 mounted on the fixed bar 42 and driven by the fingers 44 of the movable bar 45 under the influence of the spring 46, driven into the grooves 43 of the hooks 4, are removed by the detached and twisted brush fringe. The blade 45 is moved by the lever 47, turned by the cam 48, mounted on the lower cam shaft 37.

The development of fringe on the machine is as follows.

During operation of the fringe machine, the comb 10 with tongue needles 11 is advanced. 13 needles are threaded onto the needles 11 with 13 needle threads. When the needles are returned to their original position, they earn the weft yarns moved by the yarn feeders 15, as a result of which a ribbon is formed in accordance with the required fringe edge width, which is produced using jacquard apparatuses with different patterns.

At this time, the carriage 27 rises to the upper position and the twisting hooks 26 engage with the weft thread. Go down, hooks 26 pull the weft thread down. Reach bottom position carriage
