Abstract
Heat treating of sheet-like textile structures in the stiffening thereof by coating (28) with plastic or by bonding with interlinings, uses a continuous dryer (31). The dryer (31) comprises an infrared radiation heating device (37) and a contact heating device (39). The dryer thus enables, in coating, to harden the plastic applied in two phases, firstly to a moisture content of 20-30% and then to a moisture content of 0-12%. In bonding, to harmonise with respect to temperature and tension the sheet- like structures before they are supplied to the contact heating device (39). <IMAGE>

SPECIFICATION
Process and apparatus for stiffening textile
sheet-like structures
This invention relates to a process for stiffening
variously cut textile sheet-iike structures for the
manufacture of clothing, by coating the structures
with plastic, in particular to stiffening such sheet
like structures of other fabrics, in which the plastic
is applied in the form of a paste, by means of a
pressure cylinder of the type used for printing
sheet-like structures, to textile sheet-like
structures lying on a transport device, which is in
the form of a belt, and is subsequently hardened
through the action of heat in the course of the
sheet-like structures passing through a continuous
dryer.
The invention also relates to apparatus for
stiffening variously cut textile sheet-like
structures, for the manufacture of clothing, by
coating the structures with plastic in the form of a
paste, in particular for stiffening such sheet-like
structures of outer fabrics, consisting of a device for applying the plastic to textile sheet-like
structures, a device for a subsequent heat
treatment which hardens the plastic, and a transport device which is in the form of a belt for
conveying the textile sheet-like structures through these devices, of which the device for applying
plastic comprises a compression unit in which a
pressure cylinder of the type used for printing
sheet-like structures is mounted above a contact
roll, the heat-treatment device comprises a
continuous dryer with several successive drying
zones, and the transport device outside the
continuous dryer -- viewed in the transport direction -- is subdivided into several successive,
movable and couplable units which, like the
compression unit, can be moved away from the
continuous dryer.
Compared with stiffening, as is still
predominantly customary at present, by bonding
one face of the structures to adhesive-coated
interlinings, which some years ago replaced
stiffening, as was previously customary, by sewing
on interlinings, stiffening variously cut sheet-like structures for the manufacture of clothing, by
coating the structures with plastic, has the
advantage, in particular, that a considerable
saving is possible in material, labour, preparatory
work, and space and storage costs. Thus, for
example, 100 kg of paste replace more than 1 ,000 m of interlining fabric coated with adhesive.
In known processes (German
Offenlegungsschrift 2552878) and apparatus
(German Offenlegungsschrift 2922613) of the
type mentioned at the outset, the plastic which
has been applied in the form of a paste to textile
sheet-like structures is hardened in a continuous
dryer by means of non-contact heating devices in
the form of radiation heating devices, for which
infrared radiators are used. The radiation heating
devices of each successive -- viewed in the
transport direction of the transport device
drying zone of the continuous dryer can be controlled as a group and independently of the heating devices of the adjacent zone, or group by means of appropriate electrical instruments. It is also known to equip the drying zones with devices for circulating air which is present in these zones and which has been heated by the radiation heating devices.Drying, or hardening, is carried out at temperatures of about 160 to 1 800C, for example in the case of woollen fabrics, in a time of about 45 to 60 seconds (time for the sheet-like structures to pass through the continuous dryer).
In the case of a continuous dryer with three successive drying zones, for example, this leads to the following temperatures on sheet-like structures made of woollen fabric: Ist zone = 100-1 900C, llnd zone = about 1 200C and Illrd zone = about 120-1 400C. The amount of paste moisture evaporated at these temperatures is at first (1st zone) considerable and at the end (Illrd zone) only slight.
The transport device of the apparatus mentioned at the outset was subdivided outside the continuous dryer into several successive, movable and couplable units in order to ensure easy and rapid maintenance of the transport device.
A disadvantage of the known process and apparatus is that in the final drying zones of the continuous dryer the coated textile sheet-like structures lying on the transport device cannot always be supplied with heat exactly as required, and therefore the structures frequently overheat in the final drying zone, in which only a small amount of paste moisture is left to evaporate, or the plastic is not hardened satisfactorily when the heat supply is reduced to avoid the structures overheating. This also applies when textilt sheetlike structures of differing outer-fabric grade (wool, synthetic or blend fabric), colour, surface characteristics (fluffy or smooth) and density are coated lying side by side and/or in series on the transport device and are thus subsequently conveyed to the continuous dryer at the same time.The reason for this is in particular that the differences mentioned lead to differences in absorption of infrared radiation by the sheet-like structures.
It has also been found that, contrary to the original assumption according to which stiffening of textile sheet-like structures by coating the structures with plastic will in general replace stiffening by bonding with adhesive-coated interlinings, it will still be necessary to use the earlier method in some cases, thus, for example.
when stiffening sheet-like structures made of light-weight outer fabrics; namely because in this case (light-weight outer fabrics) the hardened plastic paste applied to the reverse face of the fabric is visible through the fabric from the other side. Making-up plants which manufacture clothing are thus forced, at least partially, if they wish to utilise the advantages of stiffening by coating, to operate as before or, parallel to the coating means, to operate a bonding means presently customary (German Patent 2248181).
The present invention aims to provide a process and apparatus for coating textile sheet-like structures of the type mentioned at the outset in such a way that in the final drying zones of the continuous dryer, coated textile sheet-like structures lying on the transport device can be supplied with heat exactly as the particular circumstances require and also to make it unnecessary for making-up plants which, because of the range of outer fabrics being processed in these plants, cannot dispense with stiffening of textile sheet-like structures by bonding with adhesive-coated interlinings, to operate two basically different means.
Accordingly, one aspect of the present invention provides a process for stiffening variously cut textile sheet-like structures for the manufacture of clothing, by coating the structures with plastic, in particular for stiffening such sheetlike structures of outer fabrics, in-which the plastic is applied in the form of a paste, by means of a pressure cylinder of the type used for printing sheet-like structures, to textile sheet-like structures lying on a transport device which is in the form of a belt, and is subsequently hardened through the action of heat in the course of the sheet-like structures passing through a continuous dryer, characterised in that in a first phase the plastic is hardened through contact-free action of heat down to a residual moisture content of about 30 to 20% and then, in a second phase, by means of contact heat to the predetermined final moisture content.
Another aspect of the present invention provides apparatus for stiffening variously cut textile sheet-like structures for the manufacture of clothing, by coating the structures with plastic in the form of a paste, in particular for stiffening such sheet-like structures of outer fabrics, said apparatus comprising a device for applying the plastic to textile sheet-like structures, a device for a subsequent heat treatment which hardens the plastic, and a transport device which is in the form of a belt for conveying the textile sheet-like structures through these devices, of which the device for applying plastic comprises a compression unit in which a pressure cylinder of the type used for printing sheet-like structures is mounted above a contact roll, the heat-treatment device comprises a continuous dryer with several successive drying zones, and the transport device outside the continuous dryer-viewed in the transport direction -- is subdivided into several successive, movable and couplable units which, like the compression unit, can be moved away from the continuous dryer, wherein the first drying zones of the continuous dryer have a radiation heating device and the final drying zones of the continuous dryer have a contact heating device.
The process and apparatus according to the invention enables the heat supplied in the final drying zones of the continuous dryer to coated textile sheet-like structures lying on the transport device always to match exactly the particular requirements and hence to avoid the sheet-like structures overheating or the applied plastic hardening unsatisfactorily; namely because the use of contact heat or of contact heating devices does not bring with it the absorption problem existing on application of infrared and the action of the heat can thus be controlled better than that by means of radiation.
Preferably, the various, successive actions of heat on the plastic and the sheet-like structures are effected alternately from above and below the transport plane of the sheet-like structures. The
contact heat may be supplied to the sheet-like structures alternately from below and above the transport plane of the structures.
These arrangements have a favourable effect in the abovementioned sense, because the supply of
heat to both faces evens out the warming of the plastic paste and the sheet-like structures,
reverses the partial condensation into the sheetlike structures of the paste moisture which takes place in the first drying zones with the radiation heating devices owing to the considerable extent to which this moisture evaporates there and, in the course of the evaporation of the residual moisture, very largely avoids further condensation into the sheet-like structures of paste moisture.
When successive actions of heat are effected alternately from above and below the transport plane of the sheet-like structures, the moisture condensed into the sheet-like structures is conducted away upwards, through the contact heat flow, from the downward-facing outer face of the sheet-like structures to the upward-facing coated reverse face of the sheet-like structures.
When the contact heat supply from below is followed by contact heat supply from above, the final hardening of the plastic is effected, only a very small amount of moisture being left to evaporate, again from the coated side of the sheet-like structures.
According to one embodiment of the invention, the contact heating device has electrically heated heating panels mounted below and above the transport plane of the transport device. The heating panels may be mounted in series alternately below and above the transport plane of the transport device. Thus, contact heat is supplied to both sides to the plastic paste to be hardened so as to effect a particularly uniform warming thereof.
The transport device may have within all of the drying zones an air- and vapour-impermeable and adhesive-repellent transport belt. Alternately, the transport device may have, within the first drying zones containing the radiation heating device, an air- and vapour-permeable transport belt with coarse pores, and, within the final drying zones containing the contact heating device, and air- and vapour-impermeable adhesive-repellent transport belt. The air- and vapour-impermeable and adhesive-repellent covering belt may be located above the transport belt of the transport device with a lower slack strand which is in contact with the transport belt so that it can be driven at the same speed as the transport belt.Such an arrangement avoids permanent soiling of the sides of the contact heating devices which face the sheet-like structures owing to the risk of soiling which exists as the sheet-like structures pass into the region of these heating devices due to the fact that the hardening of the plastic paste is not yet complete at this time and due to possible, basically undesirable strike-throughs of paste to the lower side of the sheet-like structures.
The continuous dryer may be used as a means for stiffening textile sheet-like structures by bonding with interlinings after front units, which do not belong to this dryer, of the transport device and of the compression unit have been moved away. The rear part of the continuous dryer which is equipped with the contact heating device and that part of the transport device which is allocated to the continuous dryer may be designed as a movable unit which can be coupled with the other part thereof. Preferably, the movable part of the continuous dryer is used as a means for coating textile sheet-like structures by bonding with interlinings after it has been moved in the transport direction of the transport device.These features enable the stiffening of textile sheet-like structures by bonding with adhesive-coated interlinings, using means which are in principle particularly favourable for coating such sheet-like structures.
Another aspect of the present invention provides a process for stiffening variously cut textile sheet-like structures for the manufacture of clothing, by bonding on one face with adhesive coated interlinings, in which the sheet-like structures are bonded to one another using heat and pressure while lying on a transport device which is in the form of a belt, in which the bonding unit formed from outer fabric and interlining is harmonised before the actual bonding process in respect of temperature and tension by exposure to infrared radiation heat. This process levels out temperature and tension in the sheet-like structures to be bonded to one another, and thus very largely avoids differential shrinkage of the sheet-like structures in the course of the actual bonding process.
Making-up plants which, because the range of outer fabrics which they have to process, have to use both stiffening processes for stiffening can thus stiffen using both processes but only one apparatus. It is thus unnecessary to operate a second apparatus, unless production in the making-up plant is sufficiently great to fully utilise two apparatus, namely one for coating and one for bonding. Even in such a case, however, where the volume of production necessitates two apparatus, the provision of two apparatus according to the invention, each of which is suitable for carrying out both stiffening processes, is in the final analysis still more favourable than the provision of single-purpose apparatus, because, for example, should one apparatus break down, both stiffening processes can then be operated on the other apparatus which is still operational.
The invention will now be further described, by way of example, with reference to the drawings, in which:
Figure 1 is a schematic side view of one embodiment of an apparatus according to the invention in which all of the drying zones of the continuous dryer are arranged fixed in position;
Figure 2 shows the apparatus of Figure 1, except that the front movable units of the transport device and the compression unit have been moved away from the continuous dryer;

Figure 4 shows the apparatus of Figure 3, except that the rear, movable drying zones have been moved, by means of the part of the transport device allocated to them, a distance away from the remaining part of the continuous dryer;
Figure 5 shows an embodiment of a continuous dryer forming part of the apparatus shown in
Figures 1 and 2;
Figure 6 shows a modification of the continuous dryer shown in Figure 5; and
Figure 7 shows an embodiment of a continuous dryer forming part of the apparatus shown in
Figures 3 and 4.
The apparatus shown in the figures consists in the first place of a device 1 3 for applying the plastic to textile sheet-like structures 10, a device 14 for heat-hardening the applied plastic, and a transport device 1 5 which consists of units 1 6 to 21. The device 1 3 consists of a compression unit 28 and of units 1 6 and 17, which in the working direction of the apparatus (arrow 51) are upstream and downstream of the compression unit and belong to the transport device 1 5. The compression unit 28 has a pressure cylinder 29 which is mounted above the transport plane of the transport device 1 5 and a contact roll 30 which is located below this transport plane.The unit 14 for hardening the plastic applied by means of the pressure cylinder 29 to the textile sheet-like structures consists of a continuous dryer 31 and units 18 to 21 of the transport device 15 which are allocated to this dryer, only one unit,18, being allocated to the continuous dryer 31 of Figure 5, two units, 1 9 and 20, being allocated to the continuous dryer 31 of Figure 6, and likewise two units, 1 9 and 21, being allocated to the continuous dryer 31 of Figure 7. The continuous dryer 31 has a radiation heating device 37 with infrared radiators 38 and a contact heating device 39 with heating panels 40 and 41. The infrared radiators 38 are located at a distance above the transport plane of the transport device 15, while the two heating panels 40 and 41 are located one behind the other alternatively below and above as well as directly on this transport plane. Pressure rolls 48 and 49 are located directly above and below the transport plane and behind the contact heating device 39, viewed in the transport direction (arrow 51) of the transport device.
The units 1 6 to 21 of the transport device 1 5 have conveyor belts 22 to 27 which are guided and can be driven by means of drive and deflection rolls 45 which are mounted in a way which is in itself known on the frames 53 to 55 of the units 1 6 and 1 7 of the transport device 1 5 and of the compression unit 28 or on the housings 57 to 60 of the continuous dryer 31. Further, to guide transport belts 22, 23 and 25 deflection edges 47 are mounted at the so-called transfer points, that is within the region of pressure cylinder 29 and contact roll 30, and within the region of the contact point of units 17 and 18, of units 17 and 19, and of units 19/21 of the transport device 1 5.
In the region of the drying zones 34 and 35 containing the contact heating device 39, a convering belt 44 is located above the transport belt 24 (Figures 1,2 and 5), transport belt 26 (Figure 6) and transport belt 27 (Figures 3, 2 and 7), the lower slack strand of which is in contact with the transport belt and which can be driven at the same speed as the transport belt. This covering belt 44 is guided and driven by means of drive and deflection rolls 46, which are likewise mounted in a way which is in itself known, in the abovementioned housings 57, 58 and 60.
Transport belts 24, 26 and 27 and the covering belt 44 are made of an air- and vapourimpermeable and adhesive-repellent material, while transport belts 22, 23 and 25 are made of an air and vapour-permeable fabric with coarse pores.
The transport belt 27 of the unit 21 (Figures 3, 4 and 7) is guided not only round the drive and deflection rolls 45 but also around a tension and balancing roll 62 which is mounted in guide rails 63 in the housing 60 so to be vertically movable.
The tending-side part of the transport belt 27 is further guided, and is pivotable in the direction of arrow 52 by means which are in themselves known but not shown, around a swivelling axis 50 mounted on the housing 60. The tending-side part of the transport belt 27 can thereby be swivelled from a position in accordance with Figure 3 into a position in accordance with Figures 4 and 7, or from a coating position into a bonding position. In
Figure 7, the coating position is also shown, by means of a dash-dot line.
The fact that the tending-side part of the transport belt 27 is pivotable makes it possible, on the one hand, to keep relatively short the intermediate zone 36 which is necessary in the continuous dryers 31 of Figures 3, 4 and 7 between the first drying zones 32 and 33 and the final drying zones 34 and 35 because the transport device 1 5 is subdivided there, and, on the other hand, to design the tending-side part of the transport belt 27 in such a way that textile sheet-like structures 11 and 12 (outer fabric and interlining) which are to be bonded to each other can conveniently be placed on this part by the operator in accordance with the requirements.
The housings 57 to 60 of the continuous dryers 31 have thermal insulation which is in itself known, and not shown, at the necessary areas.
Further, insulating sheets 42 and 43 are also located within the region of the radiation heating device 37, and the heating panels 40 and 41 of the contact heating device 39 are also insulated at the rear in a manner which is in itself known.
To move units 16 and 1 7 of the transport device 15, the compression unit 28 and the rear part of the continuous dryer 31 with unit 21 of the transport device 15, rollers 56 and 64 are located in a manner which is in itself known on the frames 53 to 55 and housing 60 thereof, and guide rails, which are not shown, for these rollers are let into the floor. To couple'and uncouple rapidly and without problems the movable units and devices with or from one another and with or from the part of the continuous dryer 31 which is arranged fixed in position, adjusting plug-in couplings, which are not shown but which are in themselves known, are provided.
Moreover, the means shown also have all parts and devices which are necessary for handling according to the invention and for operating the means properly, thus, for example, including a device for supplying the plastic paste to the pressure cylinder 29, electrical control and regulating devices for heating the heating devices 37 and 39, and an electrical overall controlling device for controlling the drives of the transport belts 22 to 27 of the transport device 1 5, the overall control device being connected to the drives, not shown, of the movable units 16 to 21 of the transport device 15 by means of flexible electrical leads which can be separated from one another.
The mode of operation of the means described for coating textile sheet-like structures within the region of the device 1 3 for applying the plastic to these structures is known, for example from
German Offenlegungsschrift 2841 594 or German Offenlegungsschrift 102. For this reason what follows will only explain the mode of operation of the device 1 4 for heat treatment when handling coated sheet-like structures and when, as an alternative, bonding textile sheet-like structures in the form of cuts of outer fabric and interlinings.
In the heat treatment, in the continuous dryer 31, with the device 13 for applying the plastic of coated sheet-like structures 10 which are in the form of cuts of outer fabric, first the greater part of the moisture contained in the plastic paste applied is evaporated in a way which is in itself known, by means of the radiation heating device 37 located in drying zones 32 and 33, according to the invention down to a residual moisture of about 30 to 20%.This residual moisture is then evaporated in drying zones 34 and 35 by means of the contact heating device 39, down to the final moisture content which is determined by the properties of the sheet-like structures and of the plastic paste and is hence predetermined and which is, for example, in the case of wool and normal paste characteristics about 8 to 12% and in the case of polyester and like-wise normal paste characteristics about 0%.
Evaporation of the residual moisture to the above-mentioned extent by means of the contact heating device 39 takes place as follows: the sheet-like structures 1 0 lying on the transport belt 24 (Figure 5) or 25 (Figure 6) are passed between the transport belt 24 and the covering belt 44 (Figure 5) or between the transport belt 26 and the covering belt 44 (Figure 6), in the prone position, first past the lower heating panel 40 and then past the upper heating panel 41 under contact pressure.The alternating heat supply which takes place in this step first reverses, in the drying zone 34, parallel to further moisture evaporation taking place there, the condensation of evaporated moisture which has taken place into the sheet-like structures in the drying zones 32 and 33 from the paste side, through the upward heat flow which is given in this drying zone 34, and then, in the final drying zone 35, evaporates the small remainder of moisture still to be evaporated. The moisture which is to be removed and which is newly evaporated is conducted away outward in this step through the lateral slots between the transport belt 24 or 26 and the covering belt 44.After this heat treatment the coated sheet-like structures which are still lying between the transport belt 24 or 26 and the covering belt 44 are conveyed through the pair of pressure rolls 48 and 49 which are located on both sides of these belts, and are in principle only intended for stiffening sheet-like structures by bonding with interlinings, but are in this case a distance apart, and after leaving the dryer housing 57 or 58, are conveyed for cooling down onto a cooling station, not shown, which is in itself known and which is downstream of the continuous dryer 31.
Adhesive-coated interlinings 1 2 can be bonded to cuts of outer fabric 11 in various ways in accordance with the above statements. In the first case (Figures 2 and 5), these sheet-like structures 11 and 12 are laid by the operator onto the end of the transport belt 24 which projects on the feed side of the continuous dryer 31, in accordance with the drawing in Figure 2. The transport belt 24 then continuously convey the sheet structures 11 and 12 through zones 32 to 35 of the continuous dryer 31 and then for cooling down onto the cooling station thereof which is not shown but which is in itself known. The differing sheet-like structures 11 and 12 (outer fabric and interlining) in the continuous dryer 31 first pass through zones 32 and 33 with the radiation heating device 37, whereby the structures are harmonised in respect of temperature and tension.This is followed by the actual bonding process in zones 34 and 35, by guiding the sheetlike structures 11 and 12, or the bonding unit 61 formed from these structures, past the electrically heated heating panels 40 and 41. In this step, the bonding unit 61 lies in a way which is in itself known between the transport belt 24 and the covering belt 44 which is located in zones 34 and 35 above the belt 24. The bonding unit 61 is finally compressed, again in a way which is in itself known, directly behind the heating panel 41 by means of pressure rolls 48 and 49. In the second case (Figures 4 and 7), the sheet-like structures 11 and 12 are bonded to each other without previous harmonising but otherwise in the same way as described above.
In the embodiment in accordance with Figure 6 of the continuous dryer 31 and of the part of the transport device 1 5 which is allocated to this dryer, which embodiment is suitable not only for stiffening sheet-like structures in the form of cuts of outer fabric 10 by coating the structures with plastic but also for stiffening cuts of outer fabric 11 by bonding with interlinings 12, the sheet-like structures, on leaving the radiation heating device 37, are passed on by transport device 25 to transport belt 26, because the transport device 1 5 is subdivided within the intermediate zone 36.
The air-impermeable and adhesive-repellent design of the transport belts 24, 26 and 27 and of the covering belt 44 avoids, not only in coating but also in bonding of sheet-like structures, permanent soiling of those sides of the heating panels 40 and 41 of the contact heating device 39 which face the sheet-like structures 1 G,11 and 12, such soiling being due to the soiling danger which exists at this time because the plastic paste has not yet completely hardened, and also avoids fundamentally undesirable strike-throughs of paste to the lower side of the sheet-like structures 10 (during coating) or of adhesive to both outer sides of the bonding unit 61 (during bonding). The removal of paste or adhesive which may adhere to the transport belts 24, 26 and 27 and/or the covering belt 44 can be effected by means of cleaning devices which are in themselves known and not shown in the figures.
