Description

The present invention relates to methods and devices for ornamenting webs flat, compressible materials by longitudinal upsetting, which do not have the ability to complete have elastic regression after the compression pressure has ceased. Materials that have these properties have, for example, woven or knitted fabrics, paper, leather, parchment, regenerated Cellulose, certain metal and synthetic resin films and impregnated textiles, such as. B. Cover screen, Imitations of leather and the like under the designation used in the description and in the claims "Ornamentation" is understood as changing the surface of parts of the track through education of curls, waves, folds and ribs or similar changes in shape, those of completely flat, in the The remaining parts at the level of the railway are limited.

With the invention, such a pattern is to be achieved without z. B. in textiles customary special weaves or chemical treatments are made use of.

The method according to the invention consists essentially in that of the full width uniform longitudinally pushed forward web at least a widthwise limited part between the surfaces of this part rest on both sides under pressure, him dodging from the feed plane obstructing surfaces of limited length is compressed, while on each previously compressed Material parts a pressure acting vertically on its surface is exerted. At least a zone of the web adjoining the zone to be compressed is allowed freedom of movement in order to avoid creases, To form crimps or the like.

For upsetting, the invention makes use of methods known per se, in which during upsetting and immediately thereafter a pressure acting perpendicularly on the surface of the web is exerted. This application of pressure is necessary so that, on the one hand, the web parts to be compressed are below the ones on them Do not dodge the feed forces brought into effect from the feed plane, on the other hand with it already compressed parts can form the necessary abutment for other parts to be compressed.

In one of these known methods, the to full width swaging web against a surface of a flexible, resiliently deformable body pressed while this surface is shortened. The pressed part of the web is removed from the shortening surface of the elastically deformable body and taken in the direction of the Shortening pushed together by the extent, method and device for ornamenting strips of flat, compressible material

Parts of the web resting on the stencil surface are compressed, while the recesses in the parts of the web opposite the stencil remain unshrunk. One between the platen and the stencil laid on the web has practically the same effect as making grooves or Recesses in the pressure roll surface itself, while one is placed between the belt and the web Template essentially has the effect of a strip with an interrupted surface. Stencils however, they can also be used together with a profiled endless belt or with profiled rollers can be used to create additional ornamental effects.

In addition, such compression devices, in which the web during the passage between fixed walls that are pressed together on both sides with pressure are pushed together in the longitudinal direction, for example, can be made usable for the zonal compression that in one or in two drive rollers and one or more longitudinal channels in one or both walls of the flow channel be provided so that one or more zones of the web are compressed in the usual way, while parts passing through the channel in the area of the grooves or depressions remain unshrunk.

Another known method for the longitudinal upsetting of flat materials consists in to convey these through between two rollers, one of which is rigid, the other is elastic Has deformable surface and revolves at a lower peripheral speed than the rigid roller. If one or both of these rollers have an interrupted surface, the one between their continuous web compressed zone by zone.

A according to the method according to the invention on certain materials, eg. B. Textiles that are in water slightly swell, the ornamentation produced can partially or completely disappear again when the material washed or otherwise wetted, unless measures are taken by which the zone-wise compression is fixed or made durable. Thermoplastic textiles are an exception, for example those made of polyamides or polyesters, such as polyethylene, terephthalate, if if they are deformed when heated, this deformation will be maintained as long as they are not at a higher level Temperature. With them the compression compression is usually accompanied by heating carried out. The fabrics are therefore heated during the upsetting.

In order to protect other textile fabrics from losing their ornamentation during washing, these treated in different ways. So they can be hardened with synthetic resins or others Fixatives are pretreated to fix the zonal shrinkage. This can harden by heating during or after upsetting or by one added after upsetting chemical substance or other chemical treatment.

As an example, a cotton fabric with a thermosetting resin in aqueous Solution impregnated and then to a suitable moisture content of for example 10% dried and cooled. Then it is ornamented and zoned by pressure upsetting finally heated to a temperature adapted to the synthetic resin used to fix the compression, after which the ornamentation is durable. One of the rollers or another component is preferably used brought the upsetting device to a temperature that is sufficient to cure the synthetic resin. If necessary, fabrics with thermoplastic properties of the synthetic resin treatment mentioned can also be used and, if necessary, subjected to subsequent heat treatment.

ίο For textiles that are wholly or partly made of cellulose acetate-rayon the ornamentation can be made permanent by using thermosetting synthetic resins, such as cotton; but if the material consists entirely of cellulose acetate or contains a high proportion of it, It can be treated with an aqueous solution of fabrics from the cellulose acetate yarns can be selectively absorbed and swell or soften them. As a result of the lowering of the At the softening point of the cellulose acetate, this can be ornamented more easily. To carry out In this process, the fabric is first treated with a solution of the swelling or softening agent of a suitable type Concentration and the excess squeezed out with HiKe on a press. The fabric will then dried and then at a suitable temperature the ornamentation process according to the invention subject. Then it is washed to remove the previously added swelling or softening agent] to detach. If the conditions are chosen correctly, the acetate rayon feels good after the treatment and ornamentation as before. With reference to the drawing, let the invention explained below using examples.

Felt or other suitable material, which is guided around two depressions in the surface of the pressure rollers 12 and 13. The pressure roller 14, the device can be run through or interrupted by means of steam supplied through the line 15. It is also possible for individual wells to be heated by, for example, 120 to 175 ° C, to run and others to be interrupted. Its depth can be adjusted in the vertical direction. It is used to vary 60, that is, they can consist for example of grooves the web of material W against the outer surface of the belt 11, the base of which is eccentric to the axis of which a pressure device runs on the contact surface. This is in Fig. 5 taking a concave shape. The rigid pressure roller 14 and 6 indicated. In this example, the depth is in the example shown a plurality of the surface of the pressure roller not in the full circumferential elevations 14 α , which are separated by grooves interrupting grooves at a circumferential point shaped depressions 14 b . All rings zero, then increases to a maximum and falls 14 "have the same outer diameter and all decrease again to zero. This creates a further channel 14 b with the same basic diameter. The rigid modification achieved in the generated pattern.

As can be seen from Fig. 7, different groove profiles can alternate on the pressing device lying next to each other. In the example shown here, a shell 17 is on a cylindrical Core 18 attached. The groove can, for example, have radial shoulders and a flat bottom, Be concave or inclined flanks and a convex base or V-shaped cross-section without flat base or radial shoulders and a concave or rounded edge have provided reason. Fig. 7 also shows the attachment of the shell 17 on the cylindrical Core 18 by means of adjusting screws 19.

Figs. 8 and 9 show different shapes of non-continuous indentations in the pressing device, which are suitable for generating different types of patterns.

The interrupted surface can also be provided on the elastically deformable body, while the pressing device has a closed smooth surface. Fig. 16 shows part of an upsetting device with a rigid roller 114 and a resilient belt 111, which is used for zone-wise upsetting. In this case, the rigid roller 114 has a closed smooth surface, while the surface of the existing guumi, felt or other flexible material and in the manner shown in Figs. 1 and 2 around two rollers is interrupted so that it is one Number of closed rings formed purple , which are separated from each other by continuous grooves 111 b.

B in place of the grooves 111, the belt surface interruptions have verschiedenster form. An example of this is shown in Fig. 17. The surface interruptions can in principle be made so deep that they completely penetrate the tape; in this case they are simply made by punching instead of cutting out pieces of tape. On the other hand, depressions can be created by molding material onto the surface.

Figure 18 shows a tape with holes of various sizes punched out of it; the parts of the Material webs that come to cover these holes during treatment remain uncompressed. The surface of the belt shown in Fig. 18 is also ribbed in the longitudinal direction, which creates a there is an additional patterning effect on the material web.

The band partially shown in Fig. 19 has a large number of small recesses 25, which on the treated web give a corresponding effect.

It is also possible to use a belt with an interrupted surface in a similar way to the pressure rollers to be built with an interrupted surface from a number of elastically deformable elements. These Elements can be guided on smooth rollers or rollers and, for example, by being arranged between them Belts of other thicknesses are kept at the desired distance from each other. But it can grooves or rings can also be provided on the rollers, through which the partial belts at the desired spacing are led from each other.

A very convenient way of making a belt with an interrupted surface is to use individual belts with a V-shaped cross-section, which are guided over rollers. Fig. 22 shows a longitudinal section through part of an upsetting machine with a rigid roller and elastic belt with a strip-shaped interrupted surface, which is composed of partial belts 26 with a V-shaped cross-section in such a way that the wider base surfaces of the partial belts rest on the guide rollers and the narrower base surfaces 26 a form the effective surface. In the exemplary embodiment shown, thinner belts 34, also with a V-shaped cross-section, are arranged between the belts 26, which keep the belts 26 at the correct distance from one another and which rest with their narrower bases on the rollers. The distance between the individual belts can also be maintained by arranging rings of suitable diameter between them on the rollers. When using V-shaped belts, special spacer elements can be dispensed with under certain circumstances, since an interrupted surface is also then possible

arises when the wedge-shaped belts with their wider contact areas on the rollers rest.

A further modification of the pattern can be produced in that the surfaces of both the pressure roller and the elastic belt have interruptions.

Instead of providing the pressing device or the elastically deformable body or both with grooves or other depressions, the interrupted surface can be placed on an additional body, e.g. B. a template may be provided which, depending on the device in which it is to be used, can be cut from a flexible, either compliant or almost rigid material. The flexible stencil can be made of metal, woven or felted fabric, paper, cardboard, rubber, or a synthetic polymer. FIG. 20 shows a flexible, endless template 27 guided around the two deflection rollers 12 and U and a tensioning roller 28 of an upsetting machine with a rigid roller and an elastic band. In this case, the stencil 27 lies between the web W to be treated and the elastically deformable belt 11. The flexible stencil 27 can, however, also be arranged between the banner W and the smooth pressure roller. In this case, in addition to this roller, it is expediently guided via a deflection roller 29 which can be rotated in a bearing that can be adjusted relative to the pressure roller. The thickness of the stencil will naturally depend on the type and degree of patterning sought and on the material to be treated, but it has been found, for example, that stencils with a thickness of 0.2 to 2 mm produce pleasing ornaments on textile fabrics and regenerated cellulose. The patterns that can be produced with the invention are different depending on the material and also depending on whether the pressing device or the elastically deformable body is provided with surface interruptions. In the case of textiles, for example, there is a tendency that the surface that comes into contact with the hard pressing device acquires a glass-like appearance or a special gloss, while the surface that comes into contact with the flexible body becomes dull and matt. It is therefore not a matter of indifference whether the interruptions are arranged in the surface of the rigid or the flexible body.

is pressed. This results in unpatterned, flat parts. When treating textile materials, the smooth parts, which are thereby increased in the longitudinal direction of the web with constant patterning, can alternate patterned parts. If it is desired that the fabric is treated with the aid of additional, heated pressure, variously ornamented agents can also be treated. In such a device, either directly or at a distance from one another, the material will follow the surface of the heated one by keeping contact with different pressure devices by means of an endless belt B with similar patterns (Fig. 3). This belt B, which presses against the web, whereby a device is always made of metal, for example, moves over the device, while one or more other three small pulleys 21, 22 and 23 are at rest. In this way, a material web entering the compression device on the left can be treated in such a way that it is more like its length under the pressure roller 14 and around it after two or more sections with different up and along the belt B around the deflection rollers Has pattern. 22 and 23 around and finally another one

Instead of the web T , a web of fabric P shown in dash-dotted lines can be treated in the same upsetting machine, which is impregnated with synthetic resin before ornamentation, dried in a drying device D , passed through the upsetting device and out of this to an oven C, in which it undergoes necessary heat treatment and from which it is brought into a suitable washing machine for washing. After washing, the fabric is dried in the usual way.

FIG. 11 schematically illustrates the sequence of a complete treatment process which comprises the ornamentation of a textile fabric according to the invention. The fabric web W coming from the left first runs through a bath F, which contains a fixing agent, for example synthetic resin, and then over a pair of nip rollers N, a drying device D, in which it is brought to the desired moisture content. The web then continues through the upsetting device 5, through the oven C and is finally wound up into a roll R.

Certain fabrics can be stretched over their entire surface by 5 to 10% of their original length before being compressed will. On the other hand, a substance can also shrink over its entire * surface below its original length before it is ornamented by pressure upsetting. This can reduce the inclination of the Parts pushed together to form puckering and folds are counteracted for shrinkage.

The fabric webs can be colored in connection with the upsetting process. For example a paste containing a dye can be applied to the elastically deformable body, the pressure roller or the stencil can be applied from where it is transferred to the fabric web during upsetting and a color pattern is generated on it. When decorating certain materials, for example Textiles, their ability can be exploited to produce certain dyes when exposed to heat to absorb. Such dyes can be applied to the web to be ornamented in the form of suspensions are applied, where it is then absorbed by those parts of the web that during the Ornaments come into contact with heated surfaces. In the other lots the dye is used either not absorbed at all or to a reduced extent. The absorption of dye is thereby reduced the higher the temperature the fabric is exposed to during ornamentation.

When treating substances that are exposed to continuous tension in later use, for example in the case of heavy curtains, this is already done by their own weight, it may be desirable be to strengthen the compressed parts to the compression and thus also the ornamentation itself to maintain against strong tensile stress. This can be done, for example, by Quilting or basting, by sewing on or sticking ribbons, or by several of these measures.

In the following some examples for the implementation of the ornamentation according to the invention are given.

Example 1 ^6s

A textile fabric made of cellulose acetate-rayon was treated with a solution of 20 percent by volume Ethyl acetate soaked in cold water. 25 to 60% of the added solution was then squeezed out and drying the fabric at a temperature of 100 ° C. The web of fabric was then compressed zone by zone, in an approximate manner as shown in Figs. 1 and 2 corresponding device whose pressure roller is heated to a temperature between 120 and 150 ° C was. The fabric was then washed in warm water and finally as free from chipping as possible dried. The ornamentation created in this way on the fabric survived the washing processes, to which such substances are usually subjected. Before ornamenting, the fabric would have to be adjusted to a certain moisture content can.

A smooth fabric made of viscose rayon fibers was brought to a moisture content of 12% and then passed through a continuously operating upsetting machine as shown in Fig. 16 of the drawing. The tape made of natural vulcanized rubber had a thickness of 8 mm and one Hardness of 55 ° Shore and had an interrupted, made up of parallel ribs 3 mm wide and intervening 7.5 mm grooves. Width and 1 mm depth. The pressure roller was heated to a temperature of 150 ° C. In those parts of the fabric that are not compressed a pattern of folds was created.

Example 3

The same fabric and device were used as in Example 2, but the fabric before ornamentation with an aqueous solution of 8 parts by weight of trimethylolmelamine and 0.1 part by weight of ammonium hydrogen phosphate impregnated, then dried and conditioned. After the ornamentation, the fabric was heated to harden the resin.

The resulting pattern was washable.

Similar results were obtained with the same treatment of mercerized cotton poplin.

Example 4

In a compression device similar to that used in Example 2, the rubber band had been replaced by a tape made of synthetic rubber 6 mm thick and a hardness of 50 ° Shore. the The interrupted work surface was formed by a number of parallel ribs 1 mm wide extending through Gutters 2 mm wide and 0.25 mm deep were separated. The pressure roller had a temperature of about 205 ° C.

In this device was a smooth fabric made exclusively of polyethylene terephthalate fibers exists, treated. The ornamentation created in the process went into washing in a watery soap solution not lost.

Example 5

This example illustrates the absorption of a dye by polyamide fibers under the action from heat.

A smooth polyamide fabric was impregnated with a dye solution and in warm air at a At a temperature of 60 ° C. The mesh

was then passed through the device described in Example 2, the tape of which is made of synthetic Rubber was made. The pressure roller was heated to a temperature of 180 ° C. The intensity of the coloring was intensified in those parts of the fabric that came into contact with the protrusions of the belt Had been brought into contact, creating a novel ornamental effect with two shades became.

The undeveloped color could have been removed by rinsing in dichloroethylene.

Example 6

A sheet of regenerated cellulose 0.04 mm thick was replaced by that described in Example 2 Device directed. The film was compressed in the areas pressed against the heated pressure roller, while the uncompressed portions were puckered.
