Located on two opposite sides of the fibrous bands of the wall of the channel throughout its width made curved and convex, and each of them is located along the channel width of the longitudinal slot to feed from a camera channel to a pair of tapes and foam liquid. The camera has means for regulating the length and width of the longitudinal slits in the curved channel walls. 1 C. p. F.-ly, 3 ill.

The invention relates to the textile industry, for equipment for spinning of natural and chemical fibers and can be used for vapor-liquid processing tapes on a tape machine.

A device for vapor-liquid processing tapes on a tape machine that contains a steam generator associated with the K/BR> However, this device has the following disadvantages:

the supply of vapor-liquid mixture in the chamber based on the principle of excess pressure, the stability of which inside the chamber is not ensured due to natural fluctuations in the air pressure outside the cell in the presence of leaking her channel;

adjusting the size of the channel, taking into account changing conditions of production of the thickness of the tapes and their number is not provided;

the asymmetric location of the tape relative to the flow of the liquid-vapor mixture determines the predominant drawing on facing the flow of the belt.

These disadvantages of the known inventions cause uneven processing of the fibers of the tape before pulling and lead to neravnoe tapes and increased waste.

Object of the invention is a device for vapor-liquid processing fibrous tapes on a tape machine, providing the technical result consists in increasing the quality of the liquid-vapor processing tape before pulling.

This technical result in the device for vapor-liquid processing fibrous tapes on a tape machine that contains a steam generator associated with the camera, and the eat, in the camera body under the passage of fibrous tapes made bath liquid and the steam generator is placed in the bath below the liquid level of the perforated tube for aeration of liquid vapor, while located on two opposite sides of the fibrous bands of the wall of the channel throughout its width made curved and convex, and each of them is located on the channel width of the longitudinal slot feed from a camera channel to a pair of tapes and foam liquid, and the camera has means for regulating the length and width of the longitudinal slits in the curved walls of the channel.

Means for regulating the width of the slits has a sickle-shaped plate mounted on the curved channel walls can be moved perpendicular to the slits, and means for changing the length of the slits is a stub installed with possibility of accommodation at the ends of the slits.

In Fig. 1 shows a General diagram of the device of Fig. 2 is a cross-section of Fig. 3 plugs.

The device comprises a chamber 1 having made her case made of corrosion-resistant material and is connected with the channel 2 for the passage of a group of fibrous tapes 3. Under Kahn is no perforated tube 6, placed in the bath 4 below the liquid level and used for its foaming steam.

Located on two opposite sides of the fibrous tapes walls 7 and 8 channel 2 throughout its width made curved and convex. The walls are located along the channel width of the longitudinal slots 9 and 10 for the feed from the camera channel to tape a pair of foamed liquid.

The camera includes means for regulating the width of the slits having a sickle-shaped plates 11 and 12, mounted on the curved channel walls can be moved perpendicular to the slits 9 and 10 and the fixing screws 13.

The camera has a means for changing the length of the slits, which are stub 14, consisting of two fixed screws halves 15 and 16 and is placed in the channel 2.

The liquid in the tub 4 is supplied via the pipe 17, and its level is maintained constant by the regulator.

The device operates as follows.

When the steam flow in the perforated tube 6 is bubbling liquid, which leads to foaming and filling the steam cavity of the camera. Foamed liquid enters the upper part of the chamber, formed by a curvilinear walls 7 and 8, and then CARICOM contact with the surface of the moving sliver 3, and the steam penetrates through the porous structure of the tape to the surfaces of the fibers.

Thus, this device is adjustable supply of expanded vapor of the liquid to the surfaces of the tapes that are located at different distances from the area of generation of foam.

The design of the device ensures uniform processing of the tapes due to the availability of funds for expansion of the liquid vapor and means for adjusting the amount of foam liquid, applied to different parts of the tapes.

1. DEVICE FOR VAPOR-liquid PROCESSING FIBROUS TAPES ON a TAPE MACHINE that contains a steam generator associated with the camera that has made its case and connected with it the passage of a group of fibrous tapes, characterized in that the camera body under the passage of fibrous tapes made bath liquid and the steam generator is placed in the bath below the liquid level of the perforated tube for aeration of liquid vapor, thus located on opposite sides of fibrous feeds the canal throughout its width made curved and convex, and each of them is located along the channel width of the longitudinal slot for feeding the width of the longitudinal slits in the curved walls of the channel.

2. The device under item 1, characterized in that the means for regulating the width of the slits has a sickle-shaped plate mounted on the curved channel walls can be moved perpendicular to the slits, and means for changing the length of the slits is a stub installed with possibility of accommodation at the ends of the slits.
