Abstract

Such an apparatus comprises a heat-insulated casing 1 in which are arranged rollers 14 for guiding the strip 12 of textile material during treatment and a ventilation device sending, via nozzle boxes 10, the treatment agent. thermal on the strip 12. In this device, a predrying section 3 equipped with rollers 14 is followed, in the direction of movement of the strip 12, by a drying section 2 equipped with tension chains clamping the edges of this band between them, these sections 2, 3 being completely enclosed in the heat-insulated envelope.

Description

  The invention relates to an apparatus for the heat treatment

  textile material made of natural and / or synthetic fibers

  ticks, having an insulated envelope in which are arranged

  rollers for guiding the textile material, a device for

  tilation apparatus for stirring a heat treatment agent in the form of gas or vapor, and nozzle boxes for applying the

  heat treatment of the strip textile material.

  Devices of this type, called clotheslines, are used to perform finishing processes, the strip textile material being fed to the apparatus with a determined moisture content and leaving the machine.

device in the dry state.

  For the efficiency of some ennobling processes,

  as well as for energy reasons, it is necessary to bring the material

  textile re-strip in the drying rack with a moisture content not exceeding

  not certain values. For this reason, one often interposes before

  a so-called pre-drying device which ensures that the machine

  fabric only enters the clothes rack with a certain content

in moisture.

  The object of the invention is to provide an apparatus for processing

  thermal insulation of a strip textile material, wherein the treatment of

  drying and heat treatment as a whole require a minimum of

  nimum of heating energy of the treatment agent.

  According to the invention, to solve the problem posed, in par-

  of the apparatus defined above, it is proposed that a section of

  drying equipped with rollers is followed, in the direction of movement of the textile material strip, a section of drying rack equipped with chains of

  voltage and that both sections are fully integrated into the

insulated veloppe.

  It is true that, overall, the apparatus according to the invention

  requires more energy than a clothes rack separate from the

  drying, while the two units installed so far separately require

  in total, more energy than the apparatus according to the invention.

  According to one embodiment of the invention, the section of

  pre-drying made up of several zones is arranged under the section of

  several zones, and the nozzle boxes in the zones

  of the pre-drying section can be protected at will, by means of

  against the action of the treatment agent in the form of gas or vapor. Thanks to this design, it is possible to vary the drying power of the predrying apparatus and thus to adapt it to a specific content.

  different moisture in the treated textile material in each case.

  According to a particularly advantageous embodiment,

  the strip textile material can be introduced into the pre-section

  drying, avoiding one or more areas thereof, passing each time through an inlet opening provided between two areas and can be closed. Finally, according to another embodiment of the invention,

  areas of the pre-drying section each form a zone with

  respondent from the clothesline section, a set of two areas.

  With this design, it is possible to compose the app-

  the same starting from sets forming areas of clothes and sets

  forming areas of drying and drying, indefinitely varied.

  An exemplary embodiment of an apparatus for heat treatment of textile web material according to the invention is shown schematically in the accompanying drawings, in which: - Figure 1 is a longitudinal sectional view of the apparatus;

  - Figure 2 is a cross sectional view of this device.

  The apparatus essentially comprises a thermal envelope

  1 which encloses a stretching section 2 running the entire length and a predrying section 3 extending from below, over half the length. Section 2 consists of two conventional clothes-drying areas 4 and two clothes-drying zones 5 each forming a set with a drying zone.

pre-drying 6.

  As shown in FIG. 2, a drying zone 5 and a pre-drying zone 6 joined together comprise a ventilation device 7 on the discharge side 8 to which are connected nozzle boxes 9 and 10, a heating device II. being provided, on the opposite side to the ventilation device 7, for the heat treatment agent under

form of gas or vapor.

  Through the clothesline section 2 run chains of

  13 which pinch between them, on both sides, the edges of the material

textile re 12.

  In the pre-drying station, guide rollers 14 are arranged in zones 6, above and below the path of the

textile material 12.

  The textile material 12 arrives from the bottom in the zones 6 of the drying section 3 and passes, on the rollers 14, through this section. The heat treatment agent in the form of gas or steam is uniformly sprayed, nozzle boxes 10, onto the textile material 12. Next, this textile material 12 arrives at the inlet 15 of the section

  to hang 1 and it is pinched by its edges between the tension chains

  13 which make it pass, in the enlarged state, through the section of drying rack 2.

  Areas 6 may be disconnected from the pre-drying section 3 which is not needed, for example by passing a shutter 16 to the closed position and thus preventing the nozzle box 10 from being cut off.

  fed as a heat treatment agent in the form of gas or vapor.

  Finally, it is possible to vary the effective length of the predrying section 3 by introducing the textile material 12 into the predrying section 3 between the predrying zones 6, through an opening

  17, avoiding one of these pre-drying zones 6.
