F.-ly, 1 Il. The invention relates to the textile industry, in particular to the spinning of natural and chemical fibers, and can be used for emulsione Rove on roving machine.A device for emulsione fibrous product on roving machine containing placed in the pipe duct with holes for aeration in the pipeline emulsion.This device has the following disadvantages: a fibrous product intensively treated side facing the area generoussandy in contact with the fibrous product of the foam cells to those of its parts, which are in the pipeline on opposite sides of the fibrous product; during stopping of the machine in contact with the foam section of fibrous material absorbs more emulsion than in the period of its operation due to different processing time foam.These drawbacks cause uneven coating of the emulsion on a fibrous product, low quality emulsione.The objective of the invention is a device providing the technical result consists in increasing the quality of emulsione fibrous product.This technical result in the device for emulsione fibrous product on roving machine containing placed in the pipe duct with holes for aeration in the pipeline emulsion is achieved by the fact that it contains in each workplace machines installed on the trajectory of the fibrous product having the form of two connected large grounds truncated cones chamber for the passage through it of the fibrous product and putting it in her emulsions in the form of films, and two connected to one end of a camera from the side of smaller founded in the pipeline, while in the chamber in the zone of the big reasons truncated cones made the cut for charging and pass through the chamber of the fibrous product.The end of each pipe is sunk into the pipeline until the duct and located coaxially his hole for aeration of the emulsion, while the number of holes of the duct corresponds to the number of nozzles.The drawing shows a General diagram of the device.The device has placed in the pipe 1 from the roving machine air duct 2 with holes 3 for expansion in the pipeline 1 emulsion and installed on each workstation of the machine in the path of movement of the fibrous product 4 camera 5 to pass through it and applying it in the chamber of the emulsion in the form of films. Camera 5 has the shape of two connected large grounds truncated cones 6 and 7. From smaller bases of the truncated cones to the camera 5 one end connected two pipe 8 and 9 for feeding the emulsion into the camera, of equal length and placed the other end in the pipe 1, flush it to the duct 2 and located coaxially his hole 3 for foaming of the emulsion. The number of holes 3 of the duct 2 corresponds to the number of nozzles.In the chamber 5 in the area of act 4.The sum of the lengths of the sections of the pipes 8 and 9 are equal one to another, that is, l1+ l2+ l3l6+ l5+ l4.The device operates as follows.When the flow in the pipe 1 from the duct 2 air emulsion foams and the nozzles 8 and 9 on levels 11 and 12 formed film. When driving the nozzles film uniformly thin, and in the area of the truncated cones camera film expand and collapse with formation of droplets 13 that are moving through the chamber 5 of the fibrous product. The equality of the lengths of the pipes provides the same transportation duration of foam from the level of the emulsion prior to its destruction. This factor causes the same degree of thinning films and equality (average) drops of the emulsion in the chamber, near the fibrous product is an aerosol cloud that creates the best conditions for its processing. The design of this device allows you to generate a flow of liquid films, each of which occupies a position perpendicular to the axis of the pipe with a certain distance between the films; closed cell foam is missing, and the phenomenon of drawing fluid stream films subject to strict laws that str is time, the foam is formed in the form of films from a strictly uniform distances from each other, and film for the upper and lower parts of the camera are identical in thickness; film destroyed as a result of Antonine with increasing area in the conical parts of the camera, this ensures uniformity of application of the emulsion; the device allows to apply the liquid directly on the product and can therefore be used for roving machines of various types. 1. DEVICE FOR EMULSIONE FIBROUS PRODUCT ON ROVING MACHINE containing placed in the pipe duct with holes for aeration in the pipeline emulsion, characterized in that it comprises at each workplace machines installed on the trajectory of the fibrous product having the form of two connected large grounds truncated cones chamber for the passage through it of the fibrous product and putting it in her emulsions in the form of films and two connected to one end of a camera from the side of smaller bases truncated cones pipe for feeding the emulsion into the camera, of equal length and placed the other end in the pipeline, while in the chamber in the zone of the big reasons osasto under item 1, characterized in that the end of each pipe is sunk in the pipeline to the duct and is aligned with its hole for aeration of the emulsion, while the number of holes of the duct corresponds to the number of nozzles.
FIELD: textile industry, in particular, non-circular weaving equipment, for example, weaving units.
SUBSTANCE: apparatus has shaft disposed between columns and adapted for carrying of rotary lever with rotating pressure roll, and spiral spring. Shaft is immovably fixed between flat columns attached by means of bolt-type protrusions to vertically arranged base. Spiral spring is mounted on shaft and spring ends are fixed on rotary lever and on one of columns. Shaft is made stepped and is equipped with basic end portions terminating in threaded parts. Flat columns have rectangular portions continued with bolt-type protrusions. Column arranged at the side of spring end has cylindrical opening for accommodation of rectilinear end of spring. Cylindrical recess provided in rotary lever hub aperture on its internal surface at the side of arrangement of spring is adapted for accommodation of rectilinear end of spring.
EFFECT: improved operating characteristics and operating conditions.

SUBSTANCE: according to the method, broken thread exiting drafting device is soaked in solution, by means of its compaction, rove is formed, and formed rove is wound onto reels of cross winding, which are chemically treated and then processed into yarn. Broken thread is soaked with electrochemically activated aqueous solution with oxidation-reduction potential from minus 1000 mV to plus 1000 mV, acidity of 2-11 pH at the temperature of 16-40°C, and produced rove, not earlier than in 30 minutes after the formation, is processed into yarn.
EFFECT: faster process of rove formation and preparation for spinning, reduced power inputs from 4200 kJ/kg to 3 J/kg and water consumption for chemical treatment of rove, rejection of chemical agents, which makes it possible to reduce costs of recycling coming as a result of chemical treatment of rove by solutions, and elimination of bulk and expensive equipment for chemical treatment of rove.

SUBSTANCE: invention relates to the textile industry, in particular to flax spinning production, where, at the last manufacturing step, to produce flax yarn the semi-finished in the form of roving is used. The method of formation and preparing flax roving for spinning, according to which, broken thread exiting drafting device is soaked in electrochemically activated water solution with an oxidation-reduction potential from minus 1000 mV to plus 1000 mV and the acidity of 2-12 pH at the temperature of 16-40°C. And the wetting is carried out directly to the cavity of the chemical reactor designed for obtaining electrochemically activated water solution.
EFFECT: invention enables to reduce the time, to reduce energy and water consumption for chemical treatment of roving, refuse chemicals which can lead to lowering disposal costs resulting from chemical processing of roving, solutions.
