The aim of the invention is the expansion of technological capabilities.

by ensuring that the nodule is shaped

 Fig, 1 shows a diagram of the proposed device; Figure 2, a mechanism for separating cylindrical exhaust rollers with an electromagnetic drive; Fig, 3 structure of the thread shaped effect knot

The device for producing shaped yarn contains spool p1 and 1 for piles 2 with core: thread 3 and arranged sequentially in the direction of movement of thread 3 thread guide wires 4, thread lithium (5, guide ridge 6 and hollow spindle 7 with element 8 false twist carrying package 9 with braiding neI bio 10, the spindle drive 7 is carried out tangently 11 "

Further along the movement of the shaped thread 12, the exhaust pair with the upper 13 and jjKKHHM 14 cylindrical rollers is located. The upper cylindrical roller 13 is mounted on the axis 15 rigidly fixed in a swinging cantilever lever 16, which serves as a mechanism for separating the rollers 13 and 14 "

The means for receiving the shaped filament 12 has a drive shaft 17 on which the winding drum 18 with a spatial groove, spring 19, brake 20 and luminaire-mounted electromagnetic clutch 21, as well as the bobbin holder 22 for the exhaust package 23, are loosely mounted. in motion due to frictional contact with the winding drum 18. The device also contains a linear actuator, exited in the form of either a pneumatic center-24, connected to an electropneumatic valve 25, or an electromagnet 26 (FIG. 2). The linear drive is kinematically connected to the lever 16 for raising the upper roller 13.

The control circuit of the device includes a start-stop unit 27, a switching unit 28, a programmer 29, a sensor 30 monitoring the breakage of a core thread 3, a compensator 31 with a converter of its angle of rotation into an electrical signal — a contact group 3.2, an electropneumatic valve 33, connected to the mains 34 compressed cart

spirit, also connected with electropneus valve 25. The inputs of unit 27 are connected to sensor 30 and converter 32, and the outputs to programmer 29 and valve ZZO. The device is also provided with a double-arm lever 36 for removing the tangential belt 11 from spindle block 7 Pneumatic cylinder 35 is connected to the outlet of the pneumatic distributor 33

The device works as follows.

The core thread 3 is unwound from the package 2, which is installed on the spool hose 1, successively passes the guide rods 4, the nitrate resident 5. The sensor 30 and the guide comb 6, With the linear speed of the outlet pair with rollers 13 and 14, it is pulled through the hollow channel the spindle 1, the loose package 9 with the braiding thread 10, and is connected to the latter with the help of a false twist element 8, forming a twisted thread 37 (Fig. 3),

Next, the thread goes around the movable low-voltage conductor of the compensator 31 and is fed to the winding drum 18 with a spatial groove, which spreads the thread on the outlet package 23 "At this moment, the winding drum 18 is pulled to the electromagnetic coupling 21; rotating at the same time with 17 ”drive shaft

The formation of shaped effects nodule occurs during a short-term supply stop with an exhaust pair with rollers 13 and 14 of the core yarn 3. At the command of the programmer 29, electropneumatic valve 25 opens access to the compressed air from the main 34 to the pneumatic cylinder 24, under the influence of which the rod moves upwards, while the upper cylindrical roller 13 from the lower roller 14, When the mechanism of the periodic stop of the core thread is made in the form of an electromagnet 26 (Fig. 2), the programmer 29 sends a signal directly to the electromagnet 26 uT, which also separates the upper cylindrical roller 13 .. At the same time disconnects elektromagnit-- hydrochloric clutch 21 via the switching unit 28. When disconnecting electromagnet-i hydrochloric clutch 21 seeps weaken attraction, the spring 19 presses the winding

drum 18 to brake 20 and stop it,

At the moment of separating the upper cylindrical roller J3 and stopping the winding drum 18, i.e. when the linear velocity of the core thread 3 is zero, the braid thread 10, descending from the package 9, informs the core thread 3 an additional number of twists, braid it. As a result, thickened sections 38 are formed along its longitudinal axis (FIG. 3).

A subsequent command of the programmer 29 returns to the initial position (lowers) the rod of the pneumatic cylinder 24 (or opens the contact of the electromagnet 26), thereby renewing the contact of the upper 13 and lower 14 cylindrical rollers. At the same time, at the command of the programmer 29, the electromagnetic clutch 21 attracts the wind drum 18 , releasing it from brake 20. The process of forming and winding the twisted thread is resumed.

The size of the knots 38, the distance between them can be set using the commands of the programmer 29, represented by

a series of electric elements of a false twist, driven

signals, the duration and intervals between which can be varied within wide limits. The duration of the signal determines the structure

and the interval between signals

corresponds to the distance between the nodules,

In the event of a breakage of the rod yarn 3, coming from the package 2, the sensor 30 is triggered. At the same time, signals are sent to the coil of the electro-pneumatic valve 33 and through the programmer 29 to the electropneumatic valve 25, Compressed air advances the rods of the pneumatic cylinders 24 and 25, the rod of the pneumatic cylinder 24 separates the upper cylindrical roller 13 from the lower roller 14,

and the pneumatic cylinder rod 35 removes the tangential belt 11 from the spindle block 7 while simultaneously braking it with a two-arm lever 36. Simultaneously, at a command from the block 37, the switching node 28 triggers, stopping the winding process of the shaped thread 12,

In case of breakage of the shaped thread 12 at the exit of the exhaust pair with rollers 13 and 14, the signal from the contacts 32 enters the block 27 and then the working bodies of the machine stop like the indicated one. After the elimination of the cause that caused the breakage of either a rod 3 or a shaped 12 threads, from block 27 (by pressing the Start button) the device is turned on,
