Abstract

Described herein is a stamped cushioning piece of a two-layered latex foam, produced with paddings in various places from a latex foam of greater specific weight. First, a layer of latex foam of slight specific weight is applied to a textile carrying sheet. Into this, depressions are stamped, whereupon a second layer of latex foam, preferably of a high specific weight, is applied. Manufacture occurs continuously on so-called large-scale machines, and the pieces are stamped out of the sheet.

Description

Die Erfindung betrifft Polsterstanzteile in der Art einer Einlegesohle oder eines Einbauteiles für Schuhe aus Latexschaum-Streichware.The invention relates to upholstery stamped parts in the manner of an insole or a built-in part for shoes made of latex foam.

Es ist bekannt, aus Latexschaum Formartikel herzustellen als einzubauende Polsterungen in der Art von Pelotten, Keilen, Fersenkissen, Fußbetten u.a. Solche Schuheinbauteile werden weiterhin auch als Polsterungen für Schaft, Achillesferse und Zunge verwendet. Sie dienen weiterhin auch als Konstruktionsteil für Schuheinlagen und Einlegesohlen.It is known to produce molded articles from latex foam as upholstery to be built in, in the manner of pads, wedges, heel cushions, footbeds and the like. Such shoe components are also used as padding for the shaft, Achilles heel and tongue. They also serve as a structural part for shoe insoles and insoles.

Diese Formartikel aus Latexschaum verlangen z.Z. jedoch noch einen hohen Anteil von Handarbeit, da die Formbleche für das Gelieren, danach für das Vulkanisieren und dann noch für das Herauslösen der Formteile in die Hand genommen werden müssen. Danach muß der Rand jedes Formstückes noch gesäubert werden. All das ist recht lohnkostenaufwendig.These molded articles made of latex foam currently require however, still a high proportion of manual work, since the shaped sheets have to be taken in hand for gelling, then for vulcanizing and then for removing the molded parts. After that, the edge of each molding still needs to be cleaned. All of this is quite labor-intensive.

Im zunehmenden Maße setzt die Schuhindustrie deshalb eine Latexschaum-Streichware ein. Diese herzustellen ist kostengünstiger. Die Schuhfabrik erhält sie als Rollenware, je nach Anwendungszweck in passender Stärke und Festigkeit. Sie muß nur noch ausgestanzt werden. An das Ausstanzen von Materialien von der Rolle ist die Schuhfabrik gewöhnt. Diese Stanzteile haben natürlich nicht so gleitende Übergänge wie Formteile. Da jedoch über die Polster stets eine festanliegende Abdeckung gezogen wird, die die Ränder des Stanzteiles stärker zusammendrückt als das übrige, entsteht dabei bei äußerer Betrachtung auch ein gewisser Übergang.The shoe industry is therefore increasingly using a latex foam spread. It is less expensive to manufacture. The shoe factory receives them as rolled goods, depending on the application in the appropriate strength and firmness. It only has to be punched out. The shoe factory is used to punching out materials from the roll. Of course, these stamped parts do not have as smooth transitions as molded parts. However, since a tight-fitting cover is always pulled over the upholstery, which compresses the edges of the stamped part more than the rest, a certain transition also arises when viewed from the outside.

Diese Streichware kann auf ein Textil oder ein Vlies gestrichen sein oder aber nur aus Latexschaum bestehen.This spreadable product can be coated on a textile or a fleece or consist only of latex foam.

Dieser gestrichene Latexschaum auf Textil oder Vlies ähnelt sehr demjenigen, der für die Herstellung von Einlegesohlen verwendet wird. Diese Einlegesohlen aus Latexschaum, die im Gegensatz zu Schuheinbauteilen einen selbständig zu verwendenden Gegenstand darstellen, haben sich aus Gründen des Marktes international in den letzten 30 Jahren vielgestaltig entwickelt. Sie haben unterschiedliche Stärken, Festigkeiten, Farben des Schaumes, Textil- oder Vliesträger, Perforationen, Beimengungen von Wirk- oder Duftstoffen, strukturierte Oberflächen des Schaumes, u.a.This painted latex foam on textile or fleece is very similar to that used for the production of insoles. These insoles made of latex foam, which, in contrast to built-in parts for shoes, are an independent item, have developed internationally in the last 30 years for reasons of the market. They have different strengths, strengths, colors of the foam, textile or fleece backing, perforations, admixtures of active ingredients or fragrances, structured surfaces of the foam, etc.

Um sich von anderen optisch abzuheben, existieren auch Sohlen mit zwei Schaumschichten verschiedener Farbe.In order to stand out visually from others, there are soles with two foam layers of different colors.

Diese Latexschaum-Streichware wird in großen Mengen als Meterware auf Anlagen von bis zu fast 100 m Länge ohne Stop mit einer Rakel, also in gleichmäßiger Höhe, abgestrichen, geliert, nach Bedarf geprägt, vulkanisiert und auf Großrolle aufgewickelt. Ein Textil oder Vlies dient als Träger, in den dann der Schaum soweit eingedrungen ist, daß dort die Reißfestigkeit nicht geringer ist als die des Schaumes selbst. Will man den Schaum ohne Träger haben, streicht man ihn auf ein Förderband, dessen Oberseite ein Trennmittel enthält.This latex foam spread is sold in bulk by the meter on systems of up to almost 100 m in length without a stop, with a squeegee, i.e. at a uniform height, gelled, embossed, vulcanized and rolled up on a large roll as required. A textile or nonwoven serves as a carrier into which the foam has penetrated to such an extent that the tensile strength is no less than that of the foam itself. If you want the foam without a carrier, you spread it on a conveyor belt, the top of which contains a release agent .

Neben den Einlegesohlen aus Latexschaum existieren Schuheinlagen aus Latexschaum. Diese werden sowohl dem individuellen Fuß orthopädisch angepaßt, oder sie werden als Handelsartikel in gewissen Formen und Größen geführt.In addition to the insoles made of latex foam, there are shoe inserts made of latex foam. These are both orthopedically adapted to the individual foot, or they are sold as merchandise in certain shapes and sizes.

Ähnlich einer solchen Schuheinlage als Handelsartikel existieren Einlegesohlen, bei denen auf dem Stanzteil aus der Streichware, also der Einlegesohle, ein oder mehrere Formartikel aus Latexschaum aufgeklebt sind als Pelotte, Gelenkstütze, Fersenkissen u.a. Diese Einlegesohle mit örtlichen Verstärkungen, die dem Fuß an diesen Stellen eine zusätzliche Unterstützung geben sollen, herzustellen, ist doppelt kostengünstig: Die Herstellung der Formartikel erfordert viel Handarbeit; dazu noch das örtlich präzise Aufkleben der Pelotten auf die Sohlen.Similar to such a shoe insert as a commercial article, there are insoles in which one or more molded articles made of latex foam are glued to the stamped part from the coated material, i.e. the insole, as a pad, joint support, heel cushion, etc. To produce this insole with local reinforcements, which should give the foot additional support at these points, is twice as inexpensive: The production of the molded articles requires a lot of manual work; in addition, the precise location of the pads on the soles.

Es ist deshalb Aufgabe der Erfindung, Polsterungen aus Latexschaum als Stanzteile, ähnlich den o.g. Formteilen und ähnlich den zuletzt beschriebenen Einlegesohlen mit Verstärkungen zu schaffen allein durch Anwenden des bekannten Streichverfahrens auf Großanlagen.It is therefore an object of the invention to use padding made of latex foam as stamped parts, similar to the above. To create molded parts and similar to the last described insoles with reinforcements simply by applying the known coating method to large systems.

Gelöst wird diese Aufgabe durch die in den Ansprüchen gekennzeichneten erfinderischen Merkmale und Verfahrensmaßnahmen.This object is achieved by the inventive features and procedural measures characterized in the claims.

Das Prägen geschieht in gewohnter Weise durch eine Prägewalze oder durch eine Flachbettpräge. Durch das Prägen entstehen durch Verdichten des Schaumes Vertiefungen, die als geformte Unterseite beim zweiten Streichen mit einem spezifisch schwereren Schaum vollgegossen werden.The embossing is done in the usual way by an embossing roller or by a flat bed embossing. The embossing creates depressions through compression of the foam, which, as the shaped underside, are filled with a specifically heavier foam during the second brushing.

Dem Ziel, daß der Latexschaum an gewissen. Stellen dichter, schwerer und also gegen Preßdruck widerstandsfähiger wird, als an anderen Stellen, kommt der Umstand noch zugute, daß schon bei der ersten Schicht der Schaum dort, wo er geprägt worden ist, auch verdichtet, also widerstandsfähiger geworden ist.The goal that the latex foam on certain. Places become denser, heavier and therefore more resistant to pressure than at other places, the fact that the foam has already been compressed where it was embossed, i.e. has become more resistant, even at the first layer.

Die Übergänge in der Form aus der ersten Schicht, also zwischen den Schäumen niederer und höherer Dichte, sind kontinuierlich und fließend und entsprechen damit denen bei den bekannten Formteilen aus Latexschaum.The transitions in the form from the first layer, that is to say between the foams of lower and higher density, are continuous and flowing and thus correspond to those in the known molded parts made of latex foam.

Die so erhaltene Latexschaum-Meterware wird nun ausgestanzt für die bekannten Verwendungszwecke. Die für das Stanzen erforderlichen Referenzpunkte erhält man schon beim Prägen durch kegelförmig vertiefte Punkte.The latex foam fabric obtained in this way is now punched out for the known uses. The reference points required for punching can be obtained by embossing points in the shape of a cone.

Besonders vorteilhaft ist die Erfindung für das Herstellen von Einlegesohlen, die sich durch die besonderen Eigenschaften örtlich verschiedener Dichte von den oben behandelten abheben.The invention is particularly advantageous for the production of insoles which stand out from those treated above due to the special properties of locally different densities.

Nach der Erfindung ist eine Einlegesohle möglich, die die Eigenschaft, ähnlich der schon genannten Sohlen mit aufgeklebten Formteilen hat. Sie hat aber nicht mehr die zusätzlichen Materialhöhen, die sich aus dem Zusammenfügen der Formteile und der Streichware ergeben, sondern nur die über die ganze Sohle gleichmäßige Höhe.According to the invention, an insole is possible which has the property, similar to the soles already mentioned, with molded parts glued on. However, it no longer has the additional material heights that result from the joining of the molded parts and the spreadable product, but only the height that is uniform over the entire sole.

Zur Herstellung von Einlegesohlen der erfindungsgemäßen Art, wird das gleiche Verfahren wie bei den Stanzteilen angewandt. Zunächst wird auf einer vorzugsweisen textilen Trägerbahn eine endlose einschichtige Latexschaum-Streichware hergestellt, in einer Dicke, die etwa der Dicke der fertigen Einlegesohle entspricht. Der Latexschaum, der für diese erste Schicht eingesetzt wird, ist vorzugsweise ein Schaum niederer Dichte, also niedrigen spezifischen Gewichtes, beispielsweise ein Schaum mit einem Gewicht von 120 kg/m3. Dieser erste Strich der kontinuierlich hergestellten Latexschaum-Streichware wird dann in bekannter Weise geliert und vermittels einer Prägewalze wird in diesen gelierten Schaum das Muster einer Einlegesohle eingeprägt, in weichem die zu polsternden Teile als mehr oder weniger tiefe Einprägungen, mit harmonischen Kantenübergängen, wie erforderlich, dargestellt sind.The same method is used to produce insoles of the type according to the invention as for the stamped parts. First, a Endless single-layer latex foam spread, made in a thickness that corresponds approximately to the thickness of the finished insole. The latex foam that is used for this first layer is preferably a foam of low density, that is, low specific weight, for example a foam with a weight of 120 kg / m 3 . This first coat of the continuously produced latex foam spread is then gelled in a known manner and by means of an embossing roller, the pattern of an insole is embossed into this gelled foam, in which the parts to be cushioned are embossed as more or less deep, with harmonious edge transitions, as required. are shown.

Wo also beispielsweise in der Mitte des Vorderfußes eine Verstärkung der Einlegesohle in Form einer herzförmigen Pelotte geschaffen werden soll, ist an dieser Stelle eine herzförmige Vertiefung geprägt, deren Ränder allmählich wieder in die Oberfläche des ersten Striches übergehen.Where, for example, a reinforcement of the insole in the form of a heart-shaped pad is to be created in the middle of the forefoot, a heart-shaped depression is embossed at this point, the edges of which gradually merge into the surface of the first line.

Auf diese Weise können unterschiedliche Einprägungen in der Kontur der Einlegesohle geschaffen werden. Nach dem Prägen wird die Bahn vulkanisiert. Nun erfolgt mit einem erneuten Durchgang durch die Großanlage der zweite Strich, mit einem Latexschaum größerer Dichte, also höheren spezifischen Gewichts, beispielsweise 360 kg/m 3.In this way, different impressions can be created in the contour of the insole. After embossing, the web is vulcanized. Now, with a renewed passage through the large-scale plant, the second stroke takes place, with a latex foam of higher density, that is, higher specific weight, for example 360 kg / m 3 .

Es ist nun leicht einzusehen, daß der zweite Strich nicht nur die endgültige Dicke der Einlegesohlen bringt, sondern auch die Vertiefungen, die eingeprägt sind, ausfüllt. Der zweite Latexschaumstrich ist also praktisch das Gußmaterial, welches in die Form gegossen wird, die in den ersten Latexschaumstrich eingeprägt ist. Der zweite Strich wird dann ebenfalls geliert und anschließend in bekannter Weise vulkanisiert. Sodann werden aus diesen zweifach gestrichenen, die fertigen Einlegesohlen bereits enthaltenden, Bahnen die einzelnen Einlegesohlen individuell ausgestanzt. Für den Gebrauch wird dann die Einlegesohle wie gewohnt umgewendet. Das Trägermaterial textiler Art bildet dann die Oberseite, wenn die Einlegesohle in den Schuh eingelegt ist. Dadurch liegt die dichtere Schaumschicht, mit den auf ihr gebildeten Verstärkungen unten und die Verstärkungen bilden Erhebungen in der ersten weicheren Latexschicht. Sie haben also genau die gewünschte Dicke und Stärke, die sie benötigen, um ihre Stützwirkung beim Tragen des Schuhs zu entfalten. Die Latexschichten können unterschiedlich gefärbt sein.It is now easy to see that the second stroke not only brings the final thickness of the insoles, but also fills the depressions that are embossed. The second layer of latex foam is thus practically the casting material which is poured into the mold which is embossed in the first layer of latex foam. The second coat is then also gelled and then vulcanized in a known manner. The individual insoles are then individually punched out from these double-coated sheets, which already contain the finished insoles. The insole is then turned over as usual for use. The backing material of textile type forms the upper side when the insole is inserted into the shoe. As a result, the denser foam layer, with the reinforcements formed on it, lies below and the reinforcements form elevations in the first softer latex layer. So they have exactly the desired thickness and strength that they need to develop their support effect when wearing the shoe. The latex layers can be colored differently.

Aus der DE-AS 1 032 521 ist bekannt, wenn es Schaumkautschuks, die kaschiert sind, mit rot zu versehen, wobei eine Masse aus beschaumter Kautschukschicht, auf ein sich bewegendes Band fließen gelassen wird und zu einer Schicht von bezeichneter Höhe eingeebnet wird. Diese Schicht, die dann geliert und vulkanisiert wird, wird mit einem Klebstoff bestrichen, darauf eine biegsame Bahn oder ein löslicher Film aufgebracht, worauf die Oberfläche unter Druck versetzt wird, um die Biegung der Schaumstäbe abzuflachen und eine Bahn oder den Film gleichförmig an die Oberfläche der Schaumschicht zu beenden. Dann wird Druck entlastet und die Schaumschicht in ihre Form zurückkehren gelassen. An dieses Material kann für dekorative Oberflächengestaltung verwendet werden. Die Verwendung eines solchen Materials für Einiegesohlen oder Polsterstanzteilen wird jedoch weder nahegelegt noch empfohlen. Es dient zur Dekoration von Wänden oder Möbeln.From DE-AS 1 032 521 it is known if it is to provide foam rubbers, which are laminated, with red, a mass of foamed rubber layer being flowed onto a moving belt and being leveled to a layer of the specified height. This layer, which is then gelled and vulcanized, is coated with an adhesive, a flexible sheet or soluble film is applied thereon, and the surface is then pressurized to flatten the bend of the foam rods and a sheet or film uniformly to the surface to finish the foam layer. Then pressure is released and the foam layer is allowed to return to its shape. This material can be used for decorative surface design. However, the use of such a material for infusion soles or upholstery stampings is neither suggested nor recommended. It is used to decorate walls or furniture.

Die US-PS 2 917 807, die sich mit Einlegesohlen befaßt, schlägt vor, diese aus einem Wollvlies herzustellen, das eine Gewebeeinlage enthält, worauf dann auf das Vlies ein Latexschaum aufgetragen wird, und zwar wird dieser Latexschaum durch ein Streichmesser in das Faservlies hineingedrückt, oder wird in das Vlies hineingesaugt und dann gehärtet.US Pat. No. 2,917,807, which deals with insoles, proposes to produce them from a wool fleece which contains a fabric insert, whereupon a latex foam is applied to the fleece, and this latex foam is pressed into the fiber fleece by a doctor knife , or is sucked into the fleece and then hardened.

Der Latexschaum dient zur Verstärkung des Faservlieses.The latex foam serves to reinforce the nonwoven.

Es ist noch darauf hinzuweisen, daß auch der relativ leichte Schaum des ersten Striches auf den Fertigungsgang bezogen, beim Prägen verdichtet wird, so daß er dem dichteren Material des Striches näher kommt. Der verdichtete Schaum des ersten Streichgangs kommt also gleichfalls dem gewünschten Zweck, der durch den zweiten Streichgang erzeugt wird, zugute.It should also be pointed out that the relatively light foam of the first stroke is related to the production process, is compressed during embossing, so that it comes closer to the thicker material of the stroke. The compressed foam of the first coating also benefits the desired purpose generated by the second coating.

Um die Stellen erhöhter Dichte für den Konsumenten sichtbar zu machen, können die Sohlen dort einen Farbdruck erhalten. Durch das Bedrukken dieser Stellen kann man außer der Farbe noch weitere Eigenschaften hinzufügen, z. B. durch Beigabe von Wirk- oder von Duftstoffen.In order to make the points of increased density visible to the consumer, the soles can be color printed there. By printing these places you can add other properties besides the color, e.g. B. by adding active ingredients or fragrances.

Die Einlegesohlen können durch die Erfindung weitere Eigenschaften bekommen als die beschriebenen. Die Meterware, aus der die Sohlen gestanzt werden, erhält gleichmäßig verteilt über die ganze Fläche eine Prägung in die erste Schicht in Form von geraden Rillen, Rillen in Wellenlinie oder im Zickzack, Rastern, Noppen u. a. So können mit der Einlegesohle Massageeffekte erreicht werden.The insoles can get other properties than those described by the invention. The yard goods, from which the soles are punched, are embossed evenly over the entire surface into the first layer in the form of straight grooves, grooves in a wavy line or in a zigzag pattern, grids, knobs and the like. a. So massage effects can be achieved with the insole.

Im Rahmen der Erfindung ist es auch möglich, durch Wahl der Schichtdicken unterschiedliche Stütz- und Federungswerte zu erreichen.In the context of the invention it is also possible to achieve different support and suspension values by choosing the layer thicknesses.

Die Erfindung wird nun zum besseren Verständnis an einem Ausführungsbeispiel erläutert, welches in der Zeichnung dargestellt ist.For a better understanding, the invention will now be explained using an exemplary embodiment which is shown in the drawing.

In der Zeichnung stellen dar:

  • Fig. 1 eine Aufsicht mit Einprägung in eine Einlegesohle in einer kontinuierlich hergestellten relativ breiten Latexschaum-Streichware,
  • Fig. 2 einen Schnitt auf der Linie 11-11 der Fig. 1,
  • Fig. 3 einen Schnitt auf der Linie III-III der Fig. 1,
  • Fig. 4 einen Schnitt auf der linie IV-IV der Fig. 1,
  • Fig. 5 eine Ansicht ähnlich Fig. 1 für die Herstellung von Einbauteilen und
  • Fig. 6 ein ausgestanztes Einbauteil.
In the drawing:
  • 1 is a plan view embossed in an insole in a continuously manufactured relatively wide latex foam spread,
  • 2 shows a section on the line 11-11 of FIG. 1,
  • 3 shows a section on the line III-III of FIG. 1,
  • 4 shows a section on the line IV-IV of FIG. 1,
  • Fig. 5 is a view similar to FIG. 1 for the manufacture of built-in parts and
  • Fig. 6 shows a punched installation part.

In Fig. 1 soll das Bezugszeichen 1 eine endlos hergestellte Latexschaumware- oder Streichware beträchtlicher Breite darstellen. Diese Streichware besteht aus einem Trägermaterial, auf dessen Oberseiten der Schaum aufgestrichen wird.In Fig. 1, the reference numeral 1 is intended to represent an endlessly manufactured latex foam or spreadable product of considerable width. This spreadable product consists of a backing material, on the top of which the foam is spread.

Dieser Latexschaum ist von geringer Dichte, sein spezifisches Gewicht beträgt beispielsweise 0,12 g/cm3. Diese Bahn 1, mit der darauf liegenden ersten Latexschaumschicht, wird nun entsprechend der gewünschten Einlegesohle geprägt. In Fig. 1 ist die Umrandungsdicke 2 die äußere Kontur. Bei 3 ist eine Pelotte angeordnet, hier soll tief geprägt werden, ebenso bei 4 und an der Ferse 5. Es entsprechen bei 3, 4 und 5 Einprägungen der dargestellten Form mit den gewünschten Übergängen zur Oberfläche 6 der ersten Latexschaumschicht. In Fig. 1 ist nur eine solche Einlegesohle auf der Bahn 1 dargestellt, in Wirklichkeit werden aber etwa 20 solcher Einprägungen nebeneinander in der Latexschaumschicht enthalten sein und jeweils für die linke oder für die rechte Sohle.This latex foam is of low density, its specific weight is, for example, 0.12 g / cm 3 . This web 1, with the first latex foam layer lying thereon, is now embossed in accordance with the desired insole. In Fig. 1, the border thickness 2 is the outer contour. At 3 a pad is arranged, here should be embossed deeply, likewise at 4 and on the heel 5. At 3, 4 and 5 impressions correspond to the shape shown with the desired transitions to surface 6 of the first latex foam layer. In Fig. 1 only one such insole is shown on the web 1, but in reality about 20 such impressions will be contained side by side in the latex foam layer and each for the left or for the right sole.

In den Figuren 2, 3 und 4 ist nun schematisch gezeigt, wie sich diese Einprägungen und der noch aufzubringende zweite Latexschaumstrich im Querschnitt zeigen. Die erste Schaumschicht ist die Schicht 7, die auf dem Trägermaterial, textiler Art 8 liegt. Die Einprägung 3 ist bei 3' in Fig. 2 gezeigt. Hier, wie auch in den anderen Figuren 3 und 4, ist schon die o.e. zweite Latexschaumschicht aufgestrichen. Dies ist dunkel schraffiert und hat das Bezugszeichen 9. Der zweite Schichtstrich füllt die Prägungen 3, 4 und 5 aus und bildet gleichzeitig den oberen glatten Abschlußstrich, wie das bei 10 in Fig. 3 insbesondere zu sehen ist.FIGS. 2, 3 and 4 now show schematically how these impressions and the second latex foam coat still to be applied are shown in cross section. The first foam layer is layer 7, which lies on the carrier material, textile type 8. The indentation 3 is shown at 3 'in FIG. 2. Here, as in the other figures 3 and 4, the above-mentioned. spread second layer of latex foam. This is shaded with dark shading and has the reference number 9. The second layer line fills the embossings 3, 4 and 5 and at the same time forms the upper smooth end line, as can be seen in particular at 10 in FIG. 3.

Es sei darauf hingewiesen, daß in den Fig. 2 und 4 die Einlegesohle bereits umgewendet ist, wie das oben beschrieben ist, so daß die textile Trägerschicht jetzt die obere Schicht der Einiegesohle bildet.It should be noted that the insole has already been turned over in FIGS. 2 and 4, as described above, so that the textile carrier layer now forms the upper layer of the insole.

Die zuletzt aufgestrichene zweite Latexschaumschicht 10 mit einem dichteren Material, vorzugsweise mit einem spezifischen Gewicht von 360 kg/ m3, bildet nun die untere Schicht. Aus den Schnittdarstellungen 2 und 4 ist nun deutlich zu erkennen, wie die dichteren und damit festeren Latexschaummassen bei 5' die Ferse von beiden Seiten stützen und wie gemäß Fig. 2 die mittlere pelottenförmige Erhebung bei 3' die vordere Fußsohle unterstützt.The last coated second latex foam layer 10 with a denser material, preferably with a specific weight of 360 kg / m 3 , now forms the lower layer. From sectional views 2 and 4 it can now be clearly seen how the denser and therefore firmer latex foam masses support the heel from both sides at 5 'and how the central pelotte-like elevation at 3' supports the front sole of the foot as shown in FIG. 2.

Wie oben dargelegt, kann die Erfindung auch zur Herstellung von EinbaUteilen Verwendung finden. Das ist in den Fig. 5 und 6 dargestellt und soll nachfolgend beschrieben werden.As stated above, the invention can also be used for the production of built-in parts. This is shown in FIGS. 5 and 6 and will be described below.

Fig. 5 entspricht der Fig. 1 zur Herstellung von Einlegesohlen, jedoch sind in der ersten Latexschaumschicht 7 Einprägungen in Form von Einbauteilen erfolgt, nämlich herzförmige Pelotten bei 3" entsprechend der Pelotte 3 in der Einlegesohle in Fig. 1 und fersenstützende Einbauteile 5" entsprechend dem Teil 5 in der Einlegesohle gemäß Fig. 1. Diese Einbauteile werden natürlich in bester Ausnutzung der Materialbahn angeordnet und werden dann auf den gepunkteten Linien 11 ausgestanzt, so daß, wie vergrößert in Fig. 6 gezeigt, ein Einbauteil in Form einer Pelotte oder einer Fersenverstärkung erhalten wird. Das Schraffierte in Fig. 6 ist das vorzugsweise aus dichterem spezifisch schwererem Latexschaum hergestellte Einbauteil, und 7 bezeichnet quasi Reste der Form.Fig. 5 corresponds to Fig. 1 for the production of insoles, but in the first latex foam layer 7 embossments have been made in the form of built-in parts, namely heart-shaped pads at 3 "corresponding to the pad 3 in the insole in Fig. 1 and heel-supporting components 5" accordingly the part 5 in the insole according to FIG. 1. These installation parts are, of course, arranged in the best possible use of the material web and are then punched out on the dotted lines 11, so that, as shown enlarged in FIG. 6, an installation part in the form of a pad or one Heel reinforcement is obtained. The hatched area in FIG. 6 is the built-in part which is preferably made from denser, specifically heavier latex foam, and 7 denotes quasi residues of the shape.

Diese Form ist, wie oben beschrieben, in spezifisch leichtem Latexschaum gebildet und wird beim Einbau so zusammengedrückt, daß nur noch eine dünne Schicht auf der Oberfläche des jeweiligen Einbauteiles verbleibt.As described above, this shape is formed in specifically light latex foam and is pressed together during installation such that only a thin layer remains on the surface of the respective installation part.
