Description

Device for treating textile belts, in particular elastic textile belts

Technical Field

The invention relates to a device for treating a textile belt, in particular an elastic textile belt, comprising at least one treatment station and a steaming station, and/or a drying station, in which the textile belt is guided in a belt turn located laterally adjacent to each other on at least two deflecting elements. In the simplest case, the invention is suitable for the finishing of textile tapes. However, the present invention is particularly advantageous for dyeing textile tapes.

Background

For example, EP 0134914 a discloses a device of the type mentioned at the outset. The deflecting element in the steaming station, over which the textile belt is guided in mutually adjacent belt turns, is formed by an open reel (open reel) arranged in the upper part and a drying cylinder (dryer) arranged in the lower part. The disadvantage is that the lower cylinder, on which the upper fabric belt portion rests firmly on the cylinder over a relatively long distance. As a result of this contact, the textile belt portion is not free to shrink, so that only a limited amount of shrinkage of the textile belt is possible during steaming and drying, so that the textile belt after final treatment exhibits an unfavourable residual shrinkage, which has an unfavourable detrimental effect on the end user. The presence of the textile strip on the cylinder during dyeing also has a detrimental effect.

Disclosure of Invention

The object of the invention is to improve a device of the type mentioned at the outset.

According to the invention, this object is achieved by an apparatus for treating a textile belt, comprising at least one treatment station and a steaming station and/or a drying station in which the textile belt is guided in a belt revolution laterally adjacent to one another on at least two deflection elements, characterized in that in the steaming station and/or the drying station the upper deflection element is configured as a roller and the lower deflection element is configured as an open-type belt reel having circumferentially distributed support rods whose angle relative to the drive shaft axis is adjustable, the roller and the support rods in each case having freely rotatable support sleeves distributed in length. In a substantial improvement, the lower deflecting element is configured as an open-type reel. The open-end tape reel provides only a small bearing area for the textile tape to be treated, so that the textile tape is less hindered in the longitudinal direction, creating a larger area for the invasion of the treatment medium than in the prior art, i.e. the treatment is more intensive and more efficient. Due to the position of the support rod (the angle of which with respect to the axis of the open belt pulley can be varied) and the rotatable support sleeve on the support rod, the necessary shortening of the length of the textile belt during the shrinking can be carried out without hindrance. This allows different rotation speeds of adjacent support sleeves to adapt the textile belt length and peripheral speed with the steaming progress, and likewise with the drying progress, and thus the degree of shrinkage.

Open tape reels also allow for longer lengths of textile tape to be accommodated in stations having a reduced overall height, which means that the throughput and performance of the apparatus is improved. The lower overall height and compact design have a beneficial effect on the operability and energy performance of the station. It is easier to insert the textile strip into the station and to monitor it. The compact design makes the temperature in the station more uniform.

Advantageous improvements of the present invention will be described below.

If the inclination of the roller with respect to the axis of the open-type reel is adjustable, it is advantageous if the inclination of the roller with respect to the axis of the drive shaft of the open-type reel is adjustable. Thus, not only the running of the tape turns of the textile tape along the open-type tape reel can be improved, but in particular the shrinkage of the textile tape, since the length of the tape turns of the textile tape caused by the degree of shrinkage decreases with decreasing distance from the roller to the open-type tape reel. This also facilitates the textile strip to undergo substantially free shrinkage, so that the residual shrinkage of the finished textile strip at the end user is also reduced.

The adjustment of the inclination of the roller and the open-type reel support lever can be performed independently of each other or in combination with each other.

Advantageously, a guide bar is located between the open-type tape reel and the roller, which guide bar is engaged between the tape revolutions and preferably matches various tape widths, and if appropriate matches the tape pitch, provides improved guidance and alignment of the tape revolutions by the guide bar engaged between the tape revolutions of the textile tape.

It is particularly advantageous if the steaming station and/or the drying station are placed in a closed housing. The performance of the apparatus is improved if a second open-ended reel and a second roller for the textile tape to be treated are placed in the steaming station and/or the drying station. In this case, it is advantageous if the second open reel has a drive which can be controlled individually by the drive of the first open reel, preferably by means of a floating drum, in order to adapt the second open reel to the degree of shrinkage of the textile tape. Preferably, the steam supply in the steaming station is located in the lower region, and the textile belt is fed in and removed from the side of the floor. By this arrangement, the concentration chamber of the steam can be uniformly spread out, thereby creating a hypoxic space. This is an ideal dyeing condition, since the textile belt is surrounded by strong steam in the steam chamber during the entire fixing, so that the dye can optimally penetrate into the textile belt and be fixed. This results in a more thorough dyeing of the textile strip, resulting in a better colour.

In the simplest case, the apparatus is configured in such a way that the treatment station is built as a finishing station, followed by a drying station.

Particularly good benefits are obtained if the apparatus is configured for dyeing a textile strip, the treatment station being built as a dyeing station, which is followed by a steaming station, a washing station, a finishing station (if appropriate) and a drying station. A particularly compact configuration of the device is achieved if the steaming station and the drying station are positioned above the washing station.

Although the apparatus is principally designed for the treatment of a single textile belt, two or three textile belts can also be processed adjacent to one another if appropriate, in particular when the textile belts are narrow.

Detailed Description

Figures 1 to 3 show an apparatus for dyeing textile tapes, preferably elastic textile tapes, having an inlet 2 for entry of a textile tape 4. The textile strip first passes through the dyeing station 6 and then enters the steaming station 8, from which steaming station 8 it enters a washing station 10 having three washing tubs 10a, 10b, 10 c. The woven belt 4 also passes through a finishing station 12 before entering a drying station 14 and is guided from the drying station to an outlet 16, from which further independent stations may follow if desired. The dyeing station 6, the washing station 10 and the finishing station 12 are of conventional design and will not be described in detail here.

As shown in particular in fig. 4 and 5, both the steaming station 8 and the dyeing station 14 have driven open reels 17, above each of which a roller 18 is arranged. The open-type tape reel 17 comprises a plurality of support rods 20 distributed circumferentially and connected to a drive shaft 24 by radial arms 22. The support bar 20 connected to the arms 22 has a plurality of support sleeves 26 (here three) distributed over the length, which in each case are mounted freely rotatably on the support bar 20 in order to facilitate free shrinkage of the textile ribbon, so that adjacent support sleeves can have different rotational speeds. The roller 18 arranged above the open reel 17 likewise has an axle 30 which is fixed to a support 32, in particular in such a way that the angle α of the axle relative to the open reel 17 can be adjusted, as shown in fig. 2 and 4. Similar to the support rods 20, the rollers 18 are provided with freely rotating support sleeves 34 which are distributed over the length of the rollers and allow individual free rotation of the support sleeves 34. Thus, also taking into account the different shrinkage characteristics of the textile tapes. Between the open tape reel 17 and the roller 18a guide rod 36 is arranged, which engages between the tape turns to guide the tape in a manner suitable for operation. The guide rods can be matched to different strip widths and strip spacings (if appropriate).

As shown in fig. 2 and 3, in the decatizing station 8 the roller 18 is inclined downwards towards the open-type tape reel 17, so that not only is the tape path of each turn of the woven tape 4 supported from the inlet side (i.e. here the left side) to the outlet side (i.e. here the right side), but at the same time also the degree of shrinkage of the woven tape is taken into account. In the drying station 14, the rollers 18 are inclined in the opposite manner, i.e. their spacing on the right side of the open reel is greater than their spacing on the left side. The right side of the drying station is the inlet side and the left side is the outlet side from which the woven belt exits the drying station. Both the steaming station 8 and the drying station 14 are provided with floating rollers 38, 40 which control the drive (not specifically illustrated) of the open-type tape reel 17 so that it is compatible with the operation of the textile tape 4.

The steaming station 8 and the drying station 14 each have a housing 42, 44. The steam generator 48 is arranged on the bottom plate 46 of the steaming station 8. The belt inlet 50 of the steaming station 8 is also located on the bottom plate 46, so that the textile belt is supplied directly to the steam chamber area of the steam generator 48 and the textile belt is subjected to intensive and uniform steaming, which facilitates fixation. A tape outlet 52 is also located on the bottom plate 46 of the steaming station 8. By this arrangement, steam losses and consequently energy losses are avoided.

According to fig. 4, the support rod 20 of the split reel 17 can be adjusted by an angle β relative to the drive shaft 24. If β is 0, the support rod 20 is aligned parallel to the drive shaft 24. In the case where β is not equal to 0, the open tape disk 17 has a conical shape. The conical shape of the open tape reel 17 can function independently or in combination with the angled roller 18.

Fig. 6 and 7 show another exemplary embodiment of the dyeing apparatus, in which the steaming station 8a and the drying station 14a each have a second open reel 17a and a second roller 18 a. This allows a higher output from these stations and a modified belt guide 54 through the steaming station 8a, the washing station 10 and the drying station 14a, as shown in fig. 6 and 7. It is also possible, if appropriate, to provide only one of the stations with the second opening reel 17a and the second roller 18 a.

According to a simplified exemplary embodiment of the present invention, the present device may be configured to perform only belt collating. In this case, the finishing station 12 can be used simply following the drying stations 14, 14a, without the dyeing station 6 of fig. 1.
