Abstract

The heating stage of a stenter, to dry the stretched fabrics, has hollow tubular carriers (18) for the guide rails (4a) and fabric movement systems (3a) over at least part of their length. Their interiors also form a feed channel (18a) for the gas guide units (19) carried by it for the fabric edge heating system (17). The gas guide units (19), for the fabric edge heating system (17), extends maximum 15-20% of the treatment length of the assembly. The gas guide units (19), are generally only in the initial treatment field, in the direction (2) of fabric travel. At least one flexible gas supply line (23) is at each gas feed channel (18a) at the hollow carrier (18), linked to the gas supply point at the pressure side of a recirculating fan. The pressure side of each recirculating fan is connected to the jet boxes by pressure lines. The flexible gas supply line (23) leads from the pressure side of the fan or as a branch from the pressure line, and is preferably fitted with a control flap (24) to set the air vol. flow. The flexible gas supply line (23) is connected to at least one jet box under the fabric (WB), at the wall away from the fabric edge, or at the end section of the jet box near the hollow carrier (18), and at the initial section of the jet box in the housing. The flexible gas line can also be connected to the inlet lock of the recirculation system for the lower jet box. Each gas guide unit is a flat gas distributor box (19), along the direction (2) of fabric travel between the guide rail (4a) towards the longitudinal edges (5a) of the fabric and the jet box. The rear side (19a) of the distributor (19), away from the fabric edge, has an open flow connection with the gas feed channel (18a) at the hollow carrier (18) over its whole length. The blower openings (22) of the distributor box (19) are continuous or interrupted jet slits, or separate jets in at least one row. A fabric edge treatment unit (17) is at each fabric transport system (3a), with a gas distribution box (19) over and/or under the fabric movement plane, as a dedicated fabric edge drying system (17).

Description

The invention relates to a device for heat treatment a continuously transported textile Material web in a wide-spread condition, according to the Preamble of claim 1.

A device of the type required is essentially from DE-U-81 11 908 in the form of a hot air drying device known. There is at least one as Additional device trained edge treatment device for additional drying of the web edges intended. If according to this known version the one example the edge treatment facilities within the actual drying device or the Dryer housing are arranged, then there instead at least one nozzle box, several of which are arranged to dry the web, a common, tubular distributor element provided, on the one hand with a supply channel and on the other hand via a common pipe socket and extendable Line sections with gas guide elements in Form of slot nozzles is connected in the area over the longitudinal web edges of chain guide rails be worn. In this known version So at least one must be used for intensive web drying in itself expedient nozzle box of the accommodation the hot air supply devices for the additional edge drying devices give way.

In contrast, in DE-C-37 06 615 is already proposed at a drying facility for textile webs separate facilities for reinforced To provide drying of the web edges, that on the guide rails for endless revolving Transport organs collection and guide boxes attached are that cover these guideways against which Material web edges have directed nozzle outlet openings and against the nozzle exit sides from above or nozzle boxes arranged underneath completely open are designed to treat treatment gas flowing out there pick up and forward to the nozzle outlet openings to be able to. Simply because of their according to the associated Nozzle boxes are completely open on one side these well-known collection and guide boxes in practice unable to do that in these areas treatment gas flowing out corresponding nozzle boxes collect in the required manner and with the necessary Gas velocity of the web edges to be dried feed. This way only one completely inadequate or even none at all significant drying effect on these web edges can be achieved.

WO 97/03331 also describes one for drying textile webs certain device known in of the additional edge drying facilities are provided. These edge drying facilities contained in one beginning at the device inlet Longitudinal section on the guide rails for the transport elements fortified and aligned parallel to it Blowpipes that are directly aligned with the web edges Nozzle openings are provided, at least an additional blower for supplying drying gas to these additional blowguns under elevated Pressure is provided and the one equipped with blowpipes Longitudinal section at least 20% and at most 50% of the length of the drying device should be. In this known device, that alone at least one additional blower for the blowpipes not just a structural one for the longitudinal edges of the web Additional effort with correspondingly high additional costs is connected, but for the accommodation of this at least one additional fan must also be appropriate installation space are created, quite aside from the additional energy costs for that at least one blower.

The invention is therefore based on the object Device according to the preamble of claim 1 create that through a relatively simple and space-saving design and arrangement of your edge treatment equipment distinguished.

This object is achieved according to the invention by the indicator of claim 1 solved.

Advantageous embodiments of the invention are the subject of subclaims.

In this heat treatment device according to the invention are the carriers for the guide rails of the Transport organs at least over part of their length designed as a tubular hollow beam, and they form a gas supply channel in the interior at the same time for the gas guiding elements they also carry of the edge treatment facilities. this means thus that according to this invention is anyway necessary Carrier designed to hold the guide rails are that at the same time they lead to separate introduction from treatment gas to those blowing the longitudinal edges of the web Gas guiding elements are used. These treatment gas supplies can be relatively easy constructed and extremely space-saving on or in the carriers the guide rails - with a common bracket with the latter - can be provided. In comparison, for example to the known device mentioned above according to DE-U-81 11 908 can therefore also for general inflation of treatment gas on the web necessary treatment gas supply elements in any Number, i.e. unhindered by treatment gas supplies to the additional edge treatment facilities be provided.

According to an advantageous embodiment of the invention is on each hollow support forming a gas supply channel a separate flexible gas supply line connected, connected to a treatment gas source stands. This creates the possibility one of the most respected Treatment gas source on the necessary treatment gas simple way via the corresponding gas supply channel to promote the associated gas guide element and from there inflate onto the corresponding web length, regardless of the working width setting of the guide rails.

In all of the exemplary embodiments described below is the heat treatment device according to the invention in the drawing in its preferred embodiment as a drying device for textile webs, and although generally in the form of a well-known Tenter frame dryer or a tenter, in which the working width of the guide rails or the latitude distance between the two transport elements adapting to the width of the treatment Web can be adjusted. Essentially according to the same principle, the invention could Device also for fixing textile Material webs are used.

With the help of FIGS. 1 and 2, let's start with the general Structure of this drying device 1 according to the invention explained. One just simplified in the drawing - dash-dotted - indicated textile web WB is during their heat treatment, i.e. during drying in the direction of arrow 2 in a wide or wide-stretched condition continuously in the longitudinal direction transported through the drying device 1 (as known per se).

For this transport of the web WB are more common Way two transport organs in the form of transport chains or needle chains 3a, 3b provided in the present Example endlessly revolve in a horizontal plane. These transport chains 3a, 3b are of one working width the width distance corresponding to the web WB from each other in associated chain guide rails 4a, 4b performed in Figure 1 for better clarity are only indicated by dash-dotted lines and which with adjustable width spacing to each other Location and arrangement of the associated transport chains 3a, 3b determine. These transport chains 3a, 3b are also - also in the usual way - with a variety of the longitudinal edges or longitudinal edges 5a, 5b of the web WB-gripping elements provided, accordingly the representation in Figure 3 as needle bars 6 or the material web longitudinal edges clamped clips 7 could be.

Above and below and across the working width the web of goods extends in the usual way Gas supply organs or gas supply boxes for inflation of treatment gas on this web WB, where in special embodiments of the device only such gas supply members above or below the web could be provided. In these examples are the gas supply elements above and below the web WB as a known upper and lower nozzle body or nozzle boxes 8 and 9 formed in at least one, but preferably in several groups are arranged together, as shown in Fig.1. In this partial plan view of FIG. 1 is also indicated, that the drying device 1 within its Device housing 10 over its treatment length in several successive treatment fields or Half fields 11a, 11b, 11c is divided, each with several nozzle boxes 8 or 9 are equipped.

In this drying device 1, the treatment gas - as is usually the case - essentially by circulating air formed, which is generated in at least one air recirculation system becomes. In the illustrated embodiment however, there are several within the device housing 10 such air recirculation systems 12 available, namely contains each treatment field or half field 11a, 11b, 11c its own air recirculation system 12. For each air recirculation system 12 belongs to at least one group of upper and lower Nozzle boxes 8, 9 and at least one circulating air fan 13, the suction side 13a via an intake duct 14 and a screen 15 with a backflow space 10a in the device housing 10 communicates while the print page 13b of this circulating air fan 13 via a pressure channel 16 to the associated nozzle boxes 8, 9 and the associated nozzle box group is connected, see above that treatment gas or drying air over the whole Web width (working width) from the nozzle sides 8a and 9a of the nozzle boxes 8 and 9 on the web WB can be inflated.

In this drying device 1 there are also edge treatment devices in the form of edge drying devices 17 for inflating separately supplied Drying air on the two web edges 5a, 5b are provided.

The guide rails 4a, 4b of the transport chains 3a, 3b are suitably on in the longitudinal direction by the Fixture housing 10 extending beams 18 attached, of which gas guiding elements 19 at the same time the edge drying devices 17 are worn. These beams or longitudinal beams 18 are at least in the area the one defined by the wide web WB Goods transport level in the transverse direction of the Device 1 adjustable in a manner known per se, so that the required working width accordingly a web to be treated WB set can be. An essential peculiarity of this Drying device according to the invention now exists in that the carrier 18 for the guide rails 4a, 4b at least over part of their length or one predetermined longitudinal section of the drying device 1 are designed as tubular hollow beams 18 which preferably a rectangular or square Have cross-section, such as the Fig.2 and 3 can be seen. These hollow beams 18 form in Now there is a gas supply channel inside each 18a for those that are also worn (fixed) Gas guide elements 19, which are essential Form part of the edge drying devices 17 and for separate and direct inflation of drying air on the respective associated web edge 5a and 5b are formed.

The formation and arrangement of an edge drying facility 17 and in particular an associated gas guiding element 19 is in particular based on the figures 3 and 4 described in more detail; however, it should be emphasized that all edge drying devices 17 and their gas guiding elements 19 are constructed in the same way.

In this first embodiment (especially figures 2 to 4) it is first assumed that everyone Transport chain 3a and 3b an edge drying device 17 with one above the web transport level (Above the web WB) arranged upper gas guide element 19 is assigned. It is convenient the gas guiding element of this edge drying device 17 in the form of a relatively flat gas or Air distribution box 19 formed, which - as can be seen in Figures 4 and 1 - in the direction of web transport 2 and thus in the longitudinal direction of the Drying device 1 extends. Furthermore, this is Air distribution box 19 in the area between that of the associated Longitudinal web edge, e.g. 5a, facing Chain guide rail, e.g. 4a, and the corresponding Nozzle boxes, e.g. the upper nozzle boxes 8, arranged. This air distribution box 19 is in the area its rear side facing away from the web edge 5a 19a, and in particular on the one located there Underside essentially along its entire length the feed channel 18a formed in the hollow support 18 (Hollow beam feed channel) in open flow connection, as shown in particular by the dashed lines in FIG indicated, arranged close to each other Air passage openings 20 and the air flow symbolizing arrows 21 can be seen. The Representations in Figures 3 and 4 also show that the air distribution box 19 at its the associated one Longitudinal web edge 5a facing front 19b with Blow-out openings 22 is provided on the area the associated web edge 5a aligned are. These blow-out openings 22 can be in the form of continuous or interrupted slot nozzles or also in the form of arranged in at least one row Single nozzles can be executed. Any air distribution box 19 thus forms one - except for the open flow connection to the hollow beam 18 and the blow-out openings 22 - essentially closed flat box.

As illustrated above all in Fig.2, but also in 1 and 4 is indicated, there is one for each Gas supply channel 18a for an edge drying device 17 forming hollow carrier 18 at least one separate one flexible gas or drying air supply line 23 connected, i.e. in the case of FIGS. 1 to 4 illustrated first embodiment is assumed that to each air distribution box 19 each edge drying device 17 at least two such Air supply lines 23 are connected. Each Air supply line 23 stands with the pressure side 13b of the or an associated recirculation fan 13 for a separate drying air supply in connection, i.e. this anyway for the corresponding nozzle boxes 8, 9 or nozzle box groups necessary air circulation fan 13 also simultaneously forms the treatment gas or drying air source for the corresponding Edge drying equipment 17. Here can use the flexible drying air supply lines 23 - as in Fig. 2 in solid lines and in Fig.1 shown in dashed lines - on each at least one nozzle box, in the present example but preferably on two lower nozzle boxes 9, for a particularly favorable supply of drying air and distribution be connected. These supply lines 23 are - as shown in Fig.2 - preferably in the area of the web WB facing rear wall 9b of the or each corresponding lower nozzle box 9 connected. It can also be preferred in each supply line 23 - as indicated in Fig. 4 - a suitable air volume control flap 24 to arrange.

As an alternative to the exemplary embodiment explained above can according to a variant indicated by dash-dotted lines any flexible gas or air supply line 23 also directly from the printed page 13b or from Pressure channel 16 of the corresponding circulating air fan 13 be branched off, although here again preferred can be, each supply line 23 with a - preferably adjustable - air volume control flap 24 (see Fig. 4).

What also the structure of the individual edge drying facilities As far as 17 is concerned, it generally will be sufficient if the gas guiding elements or Air distribution boxes 19 each over a maximum length from about 15 to a maximum of 20% of the treatment length, i.e. about the total inner length of the housing 10 of the Drying device 1, extend. Looking at in in this sense, then form the illustration in Fig.1 the treatment fields or the half fields 11a and 11b the drying device 1 an inlet field of the drying device 1 (viewed in the direction of web transport according to arrow 2). The gas guiding elements or Air distribution boxes 19 of the edge drying facilities 17 extend essentially only in the first Treatment field, i.e. depending on the one you want Drying performance may be sufficient in the area each chain guide rail 4a, 4b only over the length of the first half field 11a in the previously described Way to install air distribution boxes 19, as in Fig.1 is illustrated in solid lines, or it can in the chain guide rails 4a and 4b additionally in the second half field 11b further Air distribution boxes 19 are provided, as in Fig.1 is indicated in dash-dotted lines.

Some further design variants are as follows explained with reference to Figures 5 and 6, the same or essentially the same components as in the previous ones illustrated embodiments with the same reference numerals are provided so that another detailed Explanation of these components is unnecessary.

5 differs of the one previously explained with reference to FIGS. 1 to 4, mainly just because every transport chain 3a or 3b and thus in the area of each longitudinal web edge 5a and 5b both above the web transport level as well as below the web transport level upper and lower air distribution boxes 19 are provided, the blow-out openings 22 thus both sides of the associated web edges 5a or 5b inflate additional drying air. The top and lower air distribution boxes 19 are in turn carried by the hollow beam 18, in which a Gas supply duct 18a for one Edge drying device 17 belonging air distribution boxes 19 is formed.

The embodiment variant according to FIG. 6 differs of the exemplary embodiments or variants described above only in that in this case the Transport organs or transport chains 3a or 3b are not circulate endlessly in a horizontal plane, but in one - as partially indicated by dash-dotted lines - vertical Level. In this case, the hollow beam 18 again both the associated chain guide rails 4a and 4b as well as the air distribution boxes 19 of the associated Edge drying device 17 firmly held.

Another embodiment, such as treatment gas or drying air of each edge treatment device 17 can be supplied, is based on the Fig. 7 and 8 explained, in turn, essentially same device parts as in the previous Embodiments with the same reference numerals are provided, so that there is another one Description of these device parts largely unnecessary.

In this further exemplary embodiment according to FIG. 7 and 8, let us again assume that the device housing 10 of the drying device 1 and thus the effective treatment length of the device in several successive treatment fields or Half fields 11a, 11b, 11c, etc. is divided, similar as in the examples above. It is also assumed that this device housing 10 at its inlet end 10a for the web WB an inlet slot lock SL immediately before the first treatment field or half field 11a is formed to the inside of the Device housing 10, that is, around the actual treatment room opposite the outside of the housing 10 Sufficiently seal when incoming goods web WB.

In this example as well (Fig. 7 and 8) the longitudinal edges of the web should be 5a, 5b predominantly only in the first treatment field or half field 11a are dried, which is why there in the same way as in the first embodiment Edge drying devices 17 with dashed lines indicated air distribution boxes 19 arranged are. Only for particularly difficult to dry Longitudinal edges can also be used in the second treatment half-field 11b - as indicated by dash-dotted lines in FIG - be provided.

Of particular importance in this example (Fig. 7 and 8) now that the flexible air supply lines 23 for the air distribution boxes 19 of the edge drying devices 17 with the pressure side 25a of a circulating air fan 25 related to an air recirculation system 26 (see Fig. 8) belongs to the inlet slot lock SL is assigned and preferably an upper and a lower gas or air supply box 27 or 28 (approximately in the form of a conventional nozzle box) as well as the pressure side 25a of the circulating air fan 25 connecting these air supply boxes 27, 28 Contains pressure channel 29. The intake side of this air circulation fan 25 can - as indicated in Fig. 7 - with the recirculation air recirculation space inside the device housing 10 communicating. This air circulation system 26 of the inlet slot lock SL works preferably with higher air pressures or air speeds than those connected to the other nozzle boxes 7, 8 Air circulation systems (within the treatment fields or half fields). This makes the circulating air field suitable 26 particularly good as a treatment gas or Drying air source for the edge drying facilities 17, i.e. due to the higher air speeds can be a more intensive treatment or drying the web edges 5a, 5b can be compared with the first embodiment (Fig.1 to 3).

In principle, this embodiment could also the air supply lines 23 to the corresponding ones Edge drying devices 17 from the pressure channel 29 of the air circulation system 26 are branched off. However, it will preferred these flexible air supply lines 23 in turn - similar to the first embodiment - On the below the web WB cross lower air supply box / nozzle box extending over this web 28 on the web To connect WB facing back 28a. Doing so it also preferred this connector of the flexible Air supply lines 23 - as in particular in Fig. 8 can be seen - in the area of the hollow beams 18 in each case adjacent end portions (longitudinal portions) 28b and 28c of the lower nozzle box 28, which is why relatively short supply lines 23 to the associated Edge drying devices 17 result. This Type of connections of the air supply lines 23 can usually also in a substantially similar manner in the case described above with reference to FIGS. 1 to 3 Embodiment are provided.
