Definitions

  • the present invention relates to a flexible object, in particular a shoe insert, with a flat base body which is intended to be placed on a flat surface of an at least substantially rigid object, the base body having a first, load-bearing layer and a second material layer, which is one of the Associated sides of the base layer and whose thickness is smaller than the thickness of the base layer, and with an adhesion promoter, which is attached in places on the surface of the second material layer intended to rest on the rigid object.
  • This shoe insert includes a absorbent layer, which contains cotton-like material. There is a layer of fibers on the top of this absorbent layer, which prevents the foot of the insole user from coming into contact with the material of the absorbent layer. This is necessary because the material of the absorbent layer has a very low abrasion resistance.
  • the other surface of the absorbent layer is covered with a fleece or tissue, which are designed in such a way that they give the shoe insert the stiffness required for the use thereof.
  • the underside of this third layer of material is provided with an anti-slip covering. This anti-slip covering can completely or only partially cover the underside mentioned.
  • the object of the present invention is to specify a flexible object, in particular a shoe insert, in which it does not slip on a firm and flat surface. And if such a slip occurs, then this object should automatically get into its plane and correct position.
  • the object shown in perspective in FIG. 1 can represent part of a shoe insert.
  • the present subject matter can also form part of other items.
  • Such objects can be, for example, a textile fabric, compact plastic, glass, metal, minerals, fleece, felt, foam, leather, synthetic leather, etc.
  • Such objects can be intended to rest on a flat surface of an object, which can be made of leather, synthetic leather, wood, marble, stone, metal, glass, compact plastic or which is designed as a textile fabric. So that the description of the subject matter is easy to understand, it is set out below in connection with the use of the same as a component of a shoe insert.
  • This shoe insert has an absorbent layer 1, the thickness of which in the finished product essentially determines the thickness of this product.
  • the thickness of the absorbent layer 1 in the finished product is between approximately 1 mm and 5 mm.
  • the absorbent layer 1 expediently extends over the entire area of the shoe insert.
  • Loosely carded wadding or wadding wastes that are produced in the production of other wadding products can form the material of this absorbent layer 1.
  • the wadding can consist exclusively of cotton fibers or it can form a mixture of subordinate fibers.
  • this layer can contain cotton and rayon fibers which are connected to one another with the aid of a fiber made of a suitable material.
  • Such an adhesive fiber can be a synthetic fiber and it can in particular be a polyethylene fiber.
  • the absorbent layer can contain 70% cotton or viscose and 30% polypropylene fibers.
  • a stabilization layer 2 is assigned to the absorbent layer 1 and this stabilization layer 2 is located on that side of the absorbent layer 1 which faces the insole of the shoe.
  • the stabilization layer 2 is designed in such a way that it gives the shoe insert the rigidity required for pushing it into a shoe.
  • this layer 2 is designed so that it has an anti-slip effect when the shoe is worn.
  • the stabilization layer 2 is made of a fibrous material in which the fibers form several layers.
  • the material of this layer must be a sealable material. It can be a fleece or a tissue. If the layer 2 is made of a fleece, then it can advantageously contain vascular fibers. These fibers can be about 40mm long and their thickness can be 3.8 decitex.
  • the fibers of the fleece are connected to each other with the help of a binder. Such a mixture can contain 75% fibers and 25% binder.
  • the binder can be based on synthetic rubber.
  • this non-woven fabric 2 can also be made of 100% polypropylene. This material advantageously contains color pigments that make it easier to distinguish between the top and bottom of the shoe insert.
  • the fibers in the fleece of the stabilization layer 2 are arranged in such a way that they run parallel to one another.
  • Such one Fleece is also known as longitudinal layer fleece.
  • the direction of the fibers lying parallel to each other practically coincides with the longitudinal direction of the shoe insert. It may be advantageous if there is a non-zero angle between the direction of the fibers and the longitudinal direction of the shoe insert. This can be the case, for example, when slipping of the shoe insert at an angle to the longitudinal direction of the shoe or the same is to be prevented.
  • the stabilizing layer 2 can be made of a tissue.
  • the tissue should have a rough to wavy surface. Crepe paper, for example, can be used for such purposes.
  • the side or surface of the absorbent layer 1 facing away from the stabilization layer 2 is assigned a layer 3, which can also be referred to as a cover layer 3.
  • This cover layer 3 advantageously completely covers the upper side of the absorbent layer 1 and thus forms the upper end of the shoe insert.
  • the surface layer 3 is designed in such a way that it is permeable to foot sweat, but that it cannot be wetted by this liquid. Thanks to this training the cover layer 3 also forms, among other things, a spacer between the absorbent layer 1 and the foot of the shoe wearer.
  • the surface layer 3 is made of fibers which form at least one layer. These fibers must be made of a relatively tear-resistant material because the body weight of the user of the present shoe insert must be absorbed by these fibers, as will be seen from the following. In addition, the material of these fibers must be sealable.
  • the fibers of the surface layer 3 can form a fleece or a fabric.
  • the fleece of the cover layer 3 can be 100% polypropylene, whereby this layer or the fibers thereof can be colorless. In any case, this cover layer 3 should have a different color than the stabilization layer 2, so that the aforementioned optical or color distinction between the top and the bottom of the insole is easily possible. An easy or problem-free distinction between the two sides of the insole is necessary because only the underside of the sole has anti-slip equipment.
  • the base body 5 of the shoe insert has cutouts 6 which are made in at least one of the sides or surfaces of the base body 5.
  • cutouts 6 are made in at least one of the sides or surfaces of the base body 5.
  • Recesses from the two sides of the base body 5 are made in this.
  • These recesses can be designed as depressions or blind holes 7 or as holes or through openings 8. If the recesses 6 are designed as through holes 8, then these holes 8 should, among other things, allow or promote a flow of air across the shoe insert.
  • the depressions 7 made in the opposite sides of the base body 5 lie opposite one another. However, it is possible to implement these depressions in the opposite sides of the base body 5 in the plane of the base body 5 of the shoe insert (not shown). In such a case, the central axes of the recesses 7, which are offset from one another, do not coincide.
  • the cutouts 6 are produced in such a way that the layer material or the base body 5, which has the layers 1, 2 and 3, is guided between heated rolls of a calender.
  • the two rollers have projections, the height of which is approximately half the thickness of the shoe insert - higher projections, or the height of which is less than half of the thickness mentioned - lower projections.
  • the projections stand like spikes from the surface of the respective heated roller and they advantageously have the shape of a truncated pyramid.
  • This truncated pyramid has either a square or a rectangular base area and is connected to the roller over the larger base area thereof.
  • the mandrels are distributed on the surface of the respective heatable roller in such a way that they form patterns. If the cutouts 6 in the opposite sides of the base body 5 are to lie exactly opposite one another, then the calender rolls are driven synchronously in such a way that the central axes of the roll mandrels lying opposite one another coincide.
  • the end face of the truncated pyramid and at least a portion of the pyramid walls adjoining this end face penetrate into the layers 1, 2 and 3 of the base body 5.
  • the end face of the truncated pyramid pushes or pushes the material of layers 1 to 3 in front of this end face and brings it into the interior of the absorbent layer 1.
  • the fibers of the stabilization layer 2 and the cover layer 3 are thermoplastic, the fibers or sections thereof in the effective area of the respective mandrel become after a corresponding heating, by which sections of the side walls of the truncated pyramid adjoining the end face of the projection are pulled to the side and at the same time into the depth of the laminated body 5.
  • the thickness of these drawn sections 9 of the outer material layers 2 or 3 can be reduced if the depth of the recess 6 is greater than the diameter of the outer mouth of this recess 6.
  • These runners 9 are located in the interior of the laminated body 5, they form a lining of the side walls of the recesses 6 and the thickness of this lining 9 can decrease with the increasing depth of the recess 6.
  • the shorter or lower roll mandrel leaves a depression 7 in the laminated body 5, which also has a bottom 10 in addition to the side walls 9 mentioned.
  • the fiber material of this recess floor 10 forms a coherent layer with the fiber material of the side linings 9.
  • This base 10 is formed by the material of the outer layers 2 and 3, which has pushed the end face of the truncated pyramid in front of it.
  • the fiber material of the absorbent layer 1 is compressed between the bottoms 10 of the mutually opposite depressions 7.
  • the thickness of this fiber layer can be selected by selecting the height of the shorter roll mandrels or by changing the distance between the calender rolls.
  • Two opposing longer roll mandrels create a hole 8 in the laminated body 5.
  • the end face of the roll mandrel which has the shape of a truncated pyramid, breaks through the outer fiber layers 2 and 3 during penetration into the layers 1 to 3.
  • the remaining material of the outer fiber layers 2 and 3 as well as the material of the suction layer 1, which was initially still between the roll mandrels, is displaced from the space between the mandrel end faces when the end faces of the opposite mandrels meet and pushed to the side, where it forms material accumulations 11 . Since the material of at least the outer layers 2 and 3 is also sealable, the inner edges of the linings 9 are welded together in the opposite recesses 6 and the material accumulations 11 mentioned form the weld seam.
  • the inner wall of the hole 8 comprises two wall sections 9, each of which has the shape of the shell of a truncated pyramid.
  • the narrower parts of these truncated pyramids face one another and are connected to one another by means of the weld seam 11. Accordingly, the diameter of the hole 8 is the smallest approximately in the middle of the thickness of the base body 5.

  • the recesses 6 are designed only as depressions 7 with a base 10, then the end parts of the bent fibers of the outer fiber layers 2 and 3 are held in the region of the base 10 mentioned.

  • the recesses 6 are not only in a row (FIG. 2) but are distributed over the surface of the base body 5 (FIG. 1), the approximately arcuate sections 12 and 13 of the surface layers 2 and 3 run practically in every direction. This results in a skin 15 on the respective surface of the base body 5, which is three-dimensional and which increases the rigidity of the base body. Between the skins 15 on the two sides of the base body 5 is the material of the absorbent layer 1, which is enclosed between them and in some cases also pressed together. This improves further the rigidity of the base body 5.
  • the subject has active ingredients. These are in the form of a liquid and this liquid is enclosed in microfine gelatin capsules 16 or the like. These capsules 16 can be distributed over the surface of the cover layer 3, where they can be exposed to a direct influence on the one hand of body heat and on the other hand of foot pressure. Individual capsules 16 can also easily be located in the cutouts 6. Such capsules 16 come later to release their content, which extends the duration of effectiveness of the substances released.
  • the capsules 16 can also be accommodated in the top layer 3 or even in the layers 1 and 2 below. Under the influence of body heat and changing loads on the shoe insert, the capsules 16 are blown up and the contents thereof are released.

  • the active ingredient can be a fragrance or a specific active ingredient, such as a fungicide, antiperspirant, bactericide or the like.
  • One of the sides or surfaces 21 of the base body 5 of the flexible object is for resting on a flat surface 17 of an at least substantially rigid object.
  • This side 21 of the flexible object is provided with an adhesion promoter or adhesive medium which is only applied in places or regions.

  • the height and shape of the island 25 is chosen so that it can be well anchored in the material of the base body 5.
  • the hemispherical or cap-shaped island 25 meets this requirement well because the greatest width of the base 26 of such an island 25 lies in the area of the base 29 of the base 26.
  • the stabilization layer 2 can have a thickness of a few tenths of a millimeter. In such a case, approximately one half of the height of the hemisphere 25 can represent the base 26 and the other half of the hemisphere, which protrudes from the stabilization layer 2, the tip 27. Since the height of the base 26 is greater than the thickness of the stabilizing layer 2, the lowest and widest section 29 of the base 26 is even embedded in the material of the absorbent layer 1. Since the side walls of the hemisphere or the spherical cap, which extend from the base surface 29, converge towards the apex 28, the material of the absorbent layer 1 and of the lower outer fiber layer 2 can rest on or on these side walls and for good holding of the island 25 in the base body 5 contribute.

Diese Schuheinlage umfasst eine Saugschicht auf, welche watteähnliches Material enthält. Auf der Oberseite dieser Saugschicht befindet sich eine Schicht aus Fasern, welche verhindert, dass der Fuss des Einlagenbenützers mit dem Material der Saugschicht in Berührung kommt. Dies ist deswegen notwendig, weil das Material der Saugschicht eine sehr geringe Abriebfestigkeit aufweist. Die andere Oberfläche der Saugschicht ist mit einem Vlies oder Tissue bedeckt, welche so ausgeführt sind, dass sie der Schuheinlage die für die Verwendung derselben erforderliche Steifheit verleihen. Die Unterseite dieser dritten Materialschicht ist mit einem Antirutschbelag versehen. Dieser Antirutschbelag kann die genannte Unterseite vollständig oder nur teilweise überdecken.Flexible objects of this type are already known. One of these objects, which represents a shoe insert, is disclosed in EP-C 0 414 634. This shoe insert includes a absorbent layer, which contains cotton-like material. There is a layer of fibers on the top of this absorbent layer, which prevents the foot of the insole user from coming into contact with the material of the absorbent layer. This is necessary because the material of the absorbent layer has a very low abrasion resistance. The other surface of the absorbent layer is covered with a fleece or tissue, which are designed in such a way that they give the shoe insert the stiffness required for the use thereof. The underside of this third layer of material is provided with an anti-slip covering. This anti-slip covering can completely or only partially cover the underside mentioned.

Während der Verwendung einer solchen Schuheinlage hat es sich herausgestellt, dass der Belag, unabhängig davon, ob er die Unterseite der Schuheinlage vollständig oder nur teilweise bedeckt, die Einlage am Verrutschen in einem Schuh zwar hindert, dass er jedoch zugleich auch verhindert, dass die Einlage in ihre ursprüngliche, flache Lage zurückkehrt, wenn sie verrutscht ist. Dies wird als Nachteil der vorbekannten Schuheinlage empfunden.While using such a shoe insert, it has been found that the covering, regardless of whether it completely or partially covers the underside of the shoe insert, prevents the insert from slipping in a shoe, but at the same time also prevents the insert in returns to its original flat position when it slips. This is perceived as a disadvantage of the previously known shoe insert.

Die Aufgabe der vorliegenden Erfindung ist, einen biegsamen Gegenstand, insbesondere eine Schuheinlage, anzugeben, bei dem ein Verrutschen dieses auf einer festen und planen Oberfläche nicht vorkommt. Und wenn ein solches Verrutschen vorkommt, dann soll dieser Gegenstand in seine plane und richtige Stellung von selbst gelangen.The object of the present invention is to specify a flexible object, in particular a shoe insert, in which it does not slip on a firm and flat surface. And if such a slip occurs, then this object should automatically get into its plane and correct position.

Die genannte Aufgabe wird beim Gegenstand der eingangs genannten Gattung erfindungsgemäss so gelöst, wie dies im kennzeichnenden Teil des Anspruchs 1 definiert ist.The stated object is achieved according to the invention in the subject matter of the type mentioned at the outset, as defined in the characterizing part of claim 1.

Nachstehend werden Ausführungsmöglichkeiten der vorliegenden Erfindung anhand der beiliegenden Zeichnung näher erläutert. Es zeigt:

  • Fig. 1 perspektivisch einen flachen und biegsamen Gegenstand, welcher einen Teil beispielsweise einer Schuheinlage darstellen kann,
  • Fig. 2 in einem vertikalen Schnitt einen Ausschnitt aus einer Schuheinlage, welche den Gegenstand gemäss Fig. 1 als einen ihrer Bestandteile aufweist und
  • Fig. 3 in einer Draufsicht einen Ausschnitt aus dem Gegenstand gemäss Fig. 1.
Possible embodiments of the present invention are explained in more detail below with reference to the accompanying drawing. It shows:
  • 1 is a perspective view of a flat and flexible object, which can represent part of, for example, a shoe insert,
  • Fig. 2 in a vertical section a section of a shoe insert, which has the object of FIG. 1 as one of its components and
  • 3 shows a top view of a detail from the object according to FIG. 1.

Der in Fig. 1 perspektivisch dargestellte Gegenstand kann einen Teil einer Schuheinlage darstellen. Der vorliegende Gegenstand kann jedoch einen Bestandteil auch anderer Gegenstände darstellen. Solche Gegenstände können beispielsweise aus einem Textilgewebe, aus kompakten Kunststoff, Glas, Metall, Mineralien, Vlies, Filz, Schaumstoff, Leder, Kunstleder usw. sein. Solche Gegenstände können zum Aufliegen auf einer planen Oberfläche eines Objektes bestimmt sein, welches aus Leder, Kunstleder, Holz, Marmor, Stein, Metall, Glas, kompaktem Kunststoff sein kann oder welches als ein textiles Flächengebilde ausgeführt ist. Damit die Beschreibung des vorliegenden Gegenstandes leicht verständlich ist, wird dieser im Zusammenhang mit der Anwendung desselben als ein Bestandteil einer Schuheinlage im Nachstehenden dargelegt.The object shown in perspective in FIG. 1 can represent part of a shoe insert. However, the present subject matter can also form part of other items. Such objects can be, for example, a textile fabric, compact plastic, glass, metal, minerals, fleece, felt, foam, leather, synthetic leather, etc. Such objects can be intended to rest on a flat surface of an object, which can be made of leather, synthetic leather, wood, marble, stone, metal, glass, compact plastic or which is designed as a textile fabric. So that the description of the subject matter is easy to understand, it is set out below in connection with the use of the same as a component of a shoe insert.

In Fig. 2 ist ein Ausschnitt aus einer Schuheinlage in einem vertikalen Schnitt dargestellt, an welcher der genannte biegsame Gegenstand angewendet ist. Diese Schuheinlage weist eine saugfähige Schicht 1 auf, deren Dicke im fertigen Produkt die Dicke dieses Produktes im wesentlichen bestimmt. Die Dicke der Saugschicht 1 liegt beim fertigen Produkt zwischen etwa 1mm und 5mm. Die Saugschicht 1 erstreckt sich zweckmässigerweise über die gesamte Fläche der Schuheinlage. Locker kardierte Watte oder aber auch Watteabfälle, welche bei der Herstellung anderer Watteprodukte anfallen, können das Material dieser Saugschicht 1 bilden. Die Watte kann ausschliesslich aus Baumwollfasern bestehen oder sie kann ein Gemisch aus unterschieglichen Fasern bilden. Beispielsweise kann diese Schicht Baumwoll- und Zellwollfasern enthalten, welche mit Hilfe einer Faser aus einem geeigneten Material untereinander verbunden sind. Eine solche Klebefaser kann eine synthetische Faser sein und es kann sich insbesondere um Polyäthylen-Fasern handeln. Die Saugschicht kann 70% Baumwoll- oder Viskose- und 30% Polypropylenfasern enthalten.2 shows a section of a shoe insert in a vertical section, to which the said flexible object is applied. This shoe insert has an absorbent layer 1, the thickness of which in the finished product essentially determines the thickness of this product. The thickness of the absorbent layer 1 in the finished product is between approximately 1 mm and 5 mm. The absorbent layer 1 expediently extends over the entire area of the shoe insert. Loosely carded wadding or wadding wastes that are produced in the production of other wadding products can form the material of this absorbent layer 1. The wadding can consist exclusively of cotton fibers or it can form a mixture of subordinate fibers. For example, this layer can contain cotton and rayon fibers which are connected to one another with the aid of a fiber made of a suitable material. Such an adhesive fiber can be a synthetic fiber and it can in particular be a polyethylene fiber. The absorbent layer can contain 70% cotton or viscose and 30% polypropylene fibers.

Der Saugschicht 1 ist eine Stabilisationsschicht 2 zugeordnet und diese Stabilisationsschicht 2 befindet sich an jener Seite der Saugschicht 1, welche der Brandsohle des Schuhes zugewandt ist. Die Stabilisationsschicht 2 ist derart ausgeführt, dass sie der Schuheinlage die zum Einschieben derselben in einen Schuh erforderliche Steifigkeit verleiht. Ausserdem ist diese Schicht 2 so ausgeführt, dass sie während des Tragens des Schuhes rutschhemmend wirkt.A stabilization layer 2 is assigned to the absorbent layer 1 and this stabilization layer 2 is located on that side of the absorbent layer 1 which faces the insole of the shoe. The stabilization layer 2 is designed in such a way that it gives the shoe insert the rigidity required for pushing it into a shoe. In addition, this layer 2 is designed so that it has an anti-slip effect when the shoe is worn.

Die gegenseitige Zuordnung der genannten Schichten 1 und 2 erfolgt in der Weise, dass eine der Oberflächen der Saugschicht 1 mit einer der Oberflächen der Stabilisationsschicnt 2 verbunden ist. Es braucht kein besonderes Verfahren zum Verbinden dieser zwei Schichten 1 und 2 angewandt zu werden, weil der Zusammenhalt der bzw. aller Schichten der vorliegenden Schuheinlage durch eine besondere Art der Perforation des Einragehalbfabrikates erreicht wird. Der Perforationsvorgang ist im nachstehenden näher beschrieben.The mutual assignment of the layers 1 and 2 mentioned takes place in such a way that one of the surfaces of the absorbent layer 1 is connected to one of the surfaces of the stabilization layer 2 is. There is no need to use a special method for connecting these two layers 1 and 2, because the cohesion of the or all layers of the present shoe insert is achieved by a special type of perforation of the insert half product. The perforation process is described in more detail below.

Die Stabilisationsschicht 2 ist aus einem faserigen Material, in welchem die Fasern mehrere Lagen bilden. Das Material dieser Schicht muss ein siegelfähiges Material sein. Es kann sich dabei um ein Vlies oder um ein Tissue handeln. Wenn die Schicht 2 aus einem Vlies ist, dann kann sie vorteilhaft Vaskosefasern enthalten. Diese Fasern können etwa 40mm lang sein und deren Dicke kann 3,8 decitex betragen. Die Fasern des Vlieses sind mit Hilfe eines Bindemittels untereinander verbunden. Ein solches Gemisch kann 75% Fasern und 25% Bindemittel enthalten. Das Bindemittel kann auf der Basis von Synthesekautschuk beruhen.The stabilization layer 2 is made of a fibrous material in which the fibers form several layers. The material of this layer must be a sealable material. It can be a fleece or a tissue. If the layer 2 is made of a fleece, then it can advantageously contain vascular fibers. These fibers can be about 40mm long and their thickness can be 3.8 decitex. The fibers of the fleece are connected to each other with the help of a binder. Such a mixture can contain 75% fibers and 25% binder. The binder can be based on synthetic rubber.

Dieses Untervlies 2 kann jedoch auch zu 100% aus Polypropylen sein. Dieses Material enthält mit Vorteil Farbpigmente, welche die Unterscheidung zwischen der Oberseite und der Unterseite der Schuheinlage erleichtern.However, this non-woven fabric 2 can also be made of 100% polypropylene. This material advantageously contains color pigments that make it easier to distinguish between the top and bottom of the shoe insert.

Die Fasern im Vlies der Stabilisationsschicht 2 sind so angeordnet, dass sie parallel zueinander verlaufen. Ein solches Vlies wird auch als Längslagenvlies bezeichnet. Die Richtung der parallel zueinander liegenden Fasern fällt mit der Längsrichtung der Schuheinlage praktisch zusammen. Unter Umständen kann es von Vorteil sein, wenn es einen von Null unterschiedlichen Winkel zwischen der Richtung der Fasern und der Längsrichtung der Schuheinlage gibt. Dies kann beispielsweise dann der Fall sein, wenn ein Rutschen der Schuheinlage schräg zur Längsrichtung des Schuhes bzw. derselben verhindert werden soll.The fibers in the fleece of the stabilization layer 2 are arranged in such a way that they run parallel to one another. Such one Fleece is also known as longitudinal layer fleece. The direction of the fibers lying parallel to each other practically coincides with the longitudinal direction of the shoe insert. It may be advantageous if there is a non-zero angle between the direction of the fibers and the longitudinal direction of the shoe insert. This can be the case, for example, when slipping of the shoe insert at an angle to the longitudinal direction of the shoe or the same is to be prevented.

Bei Anwendungsfällen, in welchen man keine grosse Belastung der Schuheinlage erwartet oder in welchen die Schuheinlage ein sehr billig herzustellendes Produkt sein soll, kann die Stabilisierungsschicht 2 aus einem Tissue sein. Das Tissue soll eine möglichst rauhe bis wellige Oberfläche haben. Für solche Zwecke kann beispielsweise Krepp-Papier verwendet werden.In applications in which the shoe insert is not expected to be subjected to a great deal of stress or in which the shoe insert is to be a product which can be manufactured very cheaply, the stabilizing layer 2 can be made of a tissue. The tissue should have a rough to wavy surface. Crepe paper, for example, can be used for such purposes.

Der von der Stabilisationsschicht 2 abgewandten Seite bzw. Oberfläche der Saugschicht 1 ist eine Schicht 3 zugeordnet, welche auch als Deckschicht 3 bezeichnet werden kann. Diese Deckschicht 3 überdeckt vorteilhaft vollständig die obere Seite der Saugschicht 1 und sie bildet somit den oberen Abschluss der Schuheinlage. Die Oberflächenlage 3 ist derart ausgeführt, dass sie für Fusschweiss zwar durchlässig ist, dass sie von dieser Flüssigkeit jedoch nicht benetzbar ist. Dank dieser Ausbildung bildet die Deckschicht 3 unter anderem auch einen Abstandshalter zwischen der Saugschicht 1 und dem Fuss des Schuhträgers.The side or surface of the absorbent layer 1 facing away from the stabilization layer 2 is assigned a layer 3, which can also be referred to as a cover layer 3. This cover layer 3 advantageously completely covers the upper side of the absorbent layer 1 and thus forms the upper end of the shoe insert. The surface layer 3 is designed in such a way that it is permeable to foot sweat, but that it cannot be wetted by this liquid. Thanks to this training the cover layer 3 also forms, among other things, a spacer between the absorbent layer 1 and the foot of the shoe wearer.

Die Oberflächenlage 3 ist aus Fasern, welche zumindest eine Schicht bilden. Diese Fasern müssen aus einem verhältnismässig reissfesten Material sein, weil das Körpergewicht des Benützers der vorliegenden Schuheinlage durch diese Fasern abgefangen werden muss, wie dies aus dem Nachstehenden noch ersichtlich sein wird. Ausserdem muss das Material dieser Fasern siegelfähig sein. Die Fasern der Oberflächenlage 3 können ein Vlies oder ein Gewebe bilden.The surface layer 3 is made of fibers which form at least one layer. These fibers must be made of a relatively tear-resistant material because the body weight of the user of the present shoe insert must be absorbed by these fibers, as will be seen from the following. In addition, the material of these fibers must be sealable. The fibers of the surface layer 3 can form a fleece or a fabric.

Das Vlies der Deckschicht 3 kann zu 100% aus Polypropylen sein, wobei diese Schicht bzw. die Fasern derselben farblos sein können. Auf jeden Fall soll diese Deckschicht 3 eine andere Farbe haben als die Stabilisationsschicht 2, damit die genannte optische bzw. farbliche Unterscheidung zwischen der Oberseite und der Unterseite der Einlegesohle leicht möglich ist. Eine leichte bzw. problemlose Unterscheidung zwischen den zwei Seiten der Einlegesohle ist deswegen notwendig, weil nur die Sohlenunterseite eine rutschhemmende Ausrüstung aufweist.The fleece of the cover layer 3 can be 100% polypropylene, whereby this layer or the fibers thereof can be colorless. In any case, this cover layer 3 should have a different color than the stabilization layer 2, so that the aforementioned optical or color distinction between the top and the bottom of the insole is easily possible. An easy or problem-free distinction between the two sides of the insole is necessary because only the underside of the sole has anti-slip equipment.

Der Grundkörper 5 der Schuheinlage weist Aussparungen 6 auf, welche zumindest in einer der Seiten bzw. Oberflächen des Grundkörpers 5 ausgeführt sind. Im dargestellten Fall sind die Aussparungen von den beiden Seiten des Grundkörpers 5 her in diesem ausgeführt. Diese Aussparungen können als Vertiefungen bzw. Sacklöcher 7 oder als Löcher bzw. durchgehende Oeffnungen 8 ausgeführt sein. Wenn die Aussparungen 6 als durchgehende Löcher 8 ausgeführt sind, dann sollen diese Löcher 8 unter anderem eine Strömung von Luft quer durch die Schuheinlage erlauben bzw. begünstigen.The base body 5 of the shoe insert has cutouts 6 which are made in at least one of the sides or surfaces of the base body 5. In the case shown are the Recesses from the two sides of the base body 5 are made in this. These recesses can be designed as depressions or blind holes 7 or as holes or through openings 8. If the recesses 6 are designed as through holes 8, then these holes 8 should, among other things, allow or promote a flow of air across the shoe insert.

Im dargestellten Fall liegen die in den gegenüberliegenden Seiten des Grundkörpers 5 ausgeführten Vertiefungen 7 einander gegenüber. Es ist jedoch möglich, diese Vertiefungen in den gegenüberliegenden Seiten des Grundkörpers 5 in der Ebene des Grundkörpers 5 der Schuheinlage zueinander versetzt auszuführen (nicht dargestellt). In einem solche Fall fallen die Mittelachsen der versetzt zueinander ausgeführten Vertiefungen 7 nicht zusammen.In the case shown, the depressions 7 made in the opposite sides of the base body 5 lie opposite one another. However, it is possible to implement these depressions in the opposite sides of the base body 5 in the plane of the base body 5 of the shoe insert (not shown). In such a case, the central axes of the recesses 7, which are offset from one another, do not coincide.

Die Aussparungen 6 werden in der Weise hergestellt, dass das Schichtmaterial bzw. der Grundkörper 5, welcher die Schichten 1, 2 und 3 aufweist, zwischen beheizten Walzen eines Kalanders geführt wird. Die beiden Walzen weisen Vorsprünge auf, deren Höhe etwa der Hälfte der Dicke der Schuheinlage gleicht - höhere Vorsprünge, oder deren Höhe kleiner ist als die Hälfte der genannten Dicke - niedrigere Vorsprünge. Die Vorsprünge stehen etwa wie Dorne von der Oberfläche der jeweiligen geheizten Walze ab und sie weisen vorteilhaft die Form eines Pyramidenstumpfes auf. Dieser Pyramidenstumpf hat entweder eine quadratische oder eine rechteckige Grundfläche und er ist über die grössere Grundfläche desselben an die Walze angeschlossen. Die Dorne sind auf der Oberfläche der jeweiligen beheizbaren Walze so verteilt, dass sie Muster bilden. Wenn die Aussparungen 6 in den gegenüberliegenden Seiten des Grundkörpers 5 genau einander gegenüberliegen sollen, dann werden die Kalanderwalzen derart synchron angetrieben, dass die Mittelachsen der einander gegenüberliegenden Walzendorne zusammenfallen.The cutouts 6 are produced in such a way that the layer material or the base body 5, which has the layers 1, 2 and 3, is guided between heated rolls of a calender. The two rollers have projections, the height of which is approximately half the thickness of the shoe insert - higher projections, or the height of which is less than half of the thickness mentioned - lower projections. The projections stand like spikes from the surface of the respective heated roller and they advantageously have the shape of a truncated pyramid. This truncated pyramid has either a square or a rectangular base area and is connected to the roller over the larger base area thereof. The mandrels are distributed on the surface of the respective heatable roller in such a way that they form patterns. If the cutouts 6 in the opposite sides of the base body 5 are to lie exactly opposite one another, then the calender rolls are driven synchronously in such a way that the central axes of the roll mandrels lying opposite one another coincide.

Wenn die beheizten Vorsprünge während des Kalandrierens des Halbfabrikats einer solchen Schuhsohle in die Oberseite 3 bzw. in die Unterseite 2 des Schichtkörpers 5 eingepresst werden, dann dringen die Stirnfläche des Pyramidenstumpfes sowie zumindest ein Abschnitt der sich an diese Stirnfläche anschliessenden Pyramidenwände in die Schichten 1, 2 und 3 des Grundkörpers 5 ein. Hierbei schiebt bzw. drückt die Stirnfläche des Pyramidenstumpfes das vor dieser Stirnfläche liegende Material der Schichten 1 bis 3 vor sich und bringt dieses in das Innere der Saugschicht 1.If the heated projections are pressed into the upper side 3 or the lower side 2 of the laminated body 5 during the calendering of the semi-finished product of such a shoe sole, then the end face of the truncated pyramid and at least a portion of the pyramid walls adjoining this end face penetrate into the layers 1, 2 and 3 of the base body 5. The end face of the truncated pyramid pushes or pushes the material of layers 1 to 3 in front of this end face and brings it into the interior of the absorbent layer 1.

Da die Fasern der Stabilisierungsschicht 2 und der Deckschicht 3 thermoplastisch sind, werden die im Wirkbereich des jeweiligen Dornes vorhandenen Fasern bzw. Abschnitte derselben, nach einer entsprechenden Anwärmung, durch die sich an die Stirnfläche des Vorsprunges anschliessenden Abschnitte der Seitenwände des Pyramidenstumpfes zur Seite und zugleich in die Tiefe des Schichtkörpers 5 gezogen. Hierbei kann sich die Dicke dieser gezogenen Abschnitte 9 der äusseren Materialschichten 2 bzw. 3 verringern, wenn die Tiefe der Aussparung 6 grösser ist als der Durchmesser der äusseren Mündung dieser Aussparung 6. In dieser Weise entstehen schräg verlaufende und gegen das Innere des Grundkörpers 5 hin zusammenlaufende Materialausläufer 9 der Aussenschichten 2 und 3. Diese Ausläufer 9 befinden sich im Inneren des Schichtkörpers 5, sie bilden eine Auskleidung der Seitenwände der Aussparungen 6 und die Dicke dieser Auskleidung 9 kann mit der zunehmenden Tiefe der Aussparung 6 abnehmen.Since the fibers of the stabilization layer 2 and the cover layer 3 are thermoplastic, the fibers or sections thereof in the effective area of the respective mandrel become after a corresponding heating, by which sections of the side walls of the truncated pyramid adjoining the end face of the projection are pulled to the side and at the same time into the depth of the laminated body 5. Here, the thickness of these drawn sections 9 of the outer material layers 2 or 3 can be reduced if the depth of the recess 6 is greater than the diameter of the outer mouth of this recess 6. In this way, oblique and against the interior of the base body 5 arise converging material runners 9 of the outer layers 2 and 3. These runners 9 are located in the interior of the laminated body 5, they form a lining of the side walls of the recesses 6 and the thickness of this lining 9 can decrease with the increasing depth of the recess 6.

Der kürzere bzw. niedrigere Walzendorn hinterlässt im Schichtkörper 5 eine Vertiefung 7, welche neben den genannten Seitenwänden 9 auch einen Boden 10 aufweist. Das Fasermaterial dieses Vertiefungsbodens 10 bildet mit dem Fasermaterial der Seitenauskleidungen 9 eine zusammenhängende Schicht. Dieser Boden 10 ist durch das Material der äusseren Schichten 2 bzw. 3 gebildet, welches die Stirnfläche des einwirkenden Pyramidenstumpfes vor sich her geschoben hat. Zwischen den Böden 10 der einander gegenüberliegenden Vertiefungen 7 liegt zusammengepresst das Fasermaterial der Saugschicht 1. Die Dicke dieser Faserschicht lässt sich durch die Wahl der Höhe der kürzeren Walzendorne bzw. durch die Aenderung des Abstandes zwischen den Kalanderwalzen einstellen.The shorter or lower roll mandrel leaves a depression 7 in the laminated body 5, which also has a bottom 10 in addition to the side walls 9 mentioned. The fiber material of this recess floor 10 forms a coherent layer with the fiber material of the side linings 9. This base 10 is formed by the material of the outer layers 2 and 3, which has pushed the end face of the truncated pyramid in front of it. The fiber material of the absorbent layer 1 is compressed between the bottoms 10 of the mutually opposite depressions 7. The thickness of this fiber layer can be selected by selecting the height of the shorter roll mandrels or by changing the distance between the calender rolls.

Zwei einander gegenüberliegende längere Walzendorne erzeugen im Schichtkörper 5 ein Loch 8. Die Stirnfläche des die Form eines Pyramidenstumpfes aufweisenden Walzendornes bricht während des Eindringens in die Schichten 1 bis 3 die äusseren Faserschichten 2 und 3 durch. Das restliche Material der äusseren Faserschichten 2 und 3 sowie das Material der Saugschicht 1, welches sich zunächst noch zwischen den Walzendornen befand, wird beim Aufeinandertreffen der Stirnflächen der gegenüberliegenden Dorne aus dem Raum zwischen den Dornstirnflächen verdrängt und zur Seite geschoben, wo es Materialanhäufungen 11 bildet. Da das Material zumindest der äusseren Schichten 2 und 3 ausserdem auch siegelfähig ist, werden die inneren Ränder der Auskleidungen 9 in den gegenüberliegenden Aussparungen 6 miteinander verschweisst und die genannten Materialanhäufungen 11 bilden die Schweissnaht.Two opposing longer roll mandrels create a hole 8 in the laminated body 5. The end face of the roll mandrel, which has the shape of a truncated pyramid, breaks through the outer fiber layers 2 and 3 during penetration into the layers 1 to 3. The remaining material of the outer fiber layers 2 and 3 as well as the material of the suction layer 1, which was initially still between the roll mandrels, is displaced from the space between the mandrel end faces when the end faces of the opposite mandrels meet and pushed to the side, where it forms material accumulations 11 . Since the material of at least the outer layers 2 and 3 is also sealable, the inner edges of the linings 9 are welded together in the opposite recesses 6 and the material accumulations 11 mentioned form the weld seam.

Die innere Wandung des Loches 8 umfasst zwei Wandabschnitte 9, von welchen jeder die Form des Mantels eines Pyramidenstumpfes aufweist. Die schmäleren Partien dieser Pyramiderstumpfe sind einander zugewandt und mit Hilfe der Schweissnaht 11 miteinander verbunden. Dementsprechend ist der Durchmesser des Loches 8 etwa in der Mitte der Dicke des Grundkörpers 5 am kleinsten.The inner wall of the hole 8 comprises two wall sections 9, each of which has the shape of the shell of a truncated pyramid. The narrower parts of these truncated pyramids face one another and are connected to one another by means of the weld seam 11. Accordingly, the diameter of the hole 8 is the smallest approximately in the middle of the thickness of the base body 5.

Die Fasern der äusseren Schichten 2 und 3 haben eine Länge von beispielsweise 4cm. Der Durchmesser der Mündung der jeweiligen Aussparung 6 beträgt etwa 1mm und der Abstand zwischen zwei benachbarten Aussparungen 6 beträgt nur einige Millimeter. Zwischen zwei Aussparungen 6, welche von einer der äusseren Faserschichten 2 bzw. 3 her im Grundkörper 5 ausgeführt sind, liegt ein praktisch unverformter Abschnitt 12 bzw. 13 der betreffenden äusseren Faserschicht 2 bzw. 3.The fibers of the outer layers 2 and 3 have a length of, for example, 4 cm. The diameter of the mouth of the respective recess 6 is approximately 1 mm and the distance between two adjacent recesses 6 is only a few millimeters. A practically undeformed section 12 or 13 of the relevant outer fiber layer 2 or 3 lies between two cutouts 6, which are made in the base body 5 from one of the outer fiber layers 2 or 3.

Im Bereich der Wandabschnitte 9 sind Teile der Langen der Fasern der äusseren Schichten 2 und 3 in das Innere der Aussparungen 6 abgebogen, in die Aussparungen 6 eingezogen und dort fixiert. Wegen der angegebenen Länge der Fasern bildet die Faser ein etwa bogenförmiges bzw. gewölbtes Gebilde. Die Endpartien dieses Bogens liegen im Bereich der Wandauskleidungen 9 der Aussparungen 6, wo sie auch verankert sind. Der Mittelbereich dieses Bogens liegt im unverformten Bereich 12 bzw. 13 der Faserschicht 2 bzw. 3. Solche Bogen, von welchen es in den Faserschichten 2 und 3 eine ausserordentlich grosse Menge gibt, bilden eine Verstrebung der Schuheinlage und verleihen dieser eine Steifigkeit, welche, gemessen an einer geringen Dicke der Schuheinlage, verhältnismässig gross ist.In the area of the wall sections 9, parts of the lengths of the fibers of the outer layers 2 and 3 are bent into the interior of the recesses 6, drawn into the recesses 6 and fixed there. Because of the specified length of the fibers, the fiber forms an approximately arched or curved structure. The end parts of this arch lie in the area of the wall linings 9 of the recesses 6, where they are also anchored. The middle region of this arch lies in the undeformed region 12 or 13 of the fiber layer 2 or 3. Such arches, of which there is an extraordinarily large amount in the fiber layers 2 and 3, form a bracing of the shoe insert and give it a stiffness which measured by a small thickness of the shoe insert, is relatively large.

Bei Aussparungen 6, welche als Löcher 8 ausgeführt sind, sind die Enden der etwa bogenförmigen Faserabschnitte von einer der Faserschichten 2 bzw. 3 durch die Schweissnaht 11 im Mittelbereich des Loches 8 zusammengehalten. Mit Hilfe der Schweissnaht sind diese Faserenden mit den Enden der Fasern der gegenüberliegenden äusseren Faserschicht 3 bzw. 2 fest verbunden, welche sich ebenfalls im mittleren Bereich der Tiefe des Loches 20 befinden.With recesses 6, which are designed as holes 8 the ends of the approximately arcuate fiber sections of one of the fiber layers 2 and 3 are held together by the weld seam 11 in the central region of the hole 8. With the help of the weld seam, these fiber ends are firmly connected to the ends of the fibers of the opposite outer fiber layer 3 or 2, which are also located in the central region of the depth of the hole 20.

Wenn die Aussparungen 6 nur als Vertiefungen 7 mit einem Boden 10 ausgeführt sind, dann sind die Endpartien der verbogenen Fasern der äusseren Faserschichten 2 und 3 im Bereich des genannten Bodens 10 gehalten. Dies deswegen, weil sie im Bereich des Bodens 10 unter der Einwirkung von Hitze und Druck zusammengedrückt und zusammengeschweisst waren.If the recesses 6 are designed only as depressions 7 with a base 10, then the end parts of the bent fibers of the outer fiber layers 2 and 3 are held in the region of the base 10 mentioned. This is because they were compressed and welded together in the area of the floor 10 under the action of heat and pressure.

Da die Aussparungen 6 nicht nur in einer Reihe liegen (Fig. 2) sondern über die Oberfläche des Grundkörpers 5 (Fig. 1) verteilt sind, verlaufen die etwa bogenförmigen Abschnitte 12 bzw. 13 der Oberflächenschichten 2 und 3 praktisch in jeder Richtung. Daraus ergibt sich eine Haut 15 auf der jeweiligen Oberfläche des Grundkörpers 5, welche dreidimensional ist und welche die Steifigkeit des Grundkörpers erhöht. Zwischen den Häuten 15 an den beiden Seiten des Grundkörpers 5 liegt das Material der Saugschicht 1, welches zwischen diesen eingeschlossen und teilweise auch zusammengepresst ist. Dies verbessert weiter die Steifigkeit des Grundkörpers 5.Since the recesses 6 are not only in a row (FIG. 2) but are distributed over the surface of the base body 5 (FIG. 1), the approximately arcuate sections 12 and 13 of the surface layers 2 and 3 run practically in every direction. This results in a skin 15 on the respective surface of the base body 5, which is three-dimensional and which increases the rigidity of the base body. Between the skins 15 on the two sides of the base body 5 is the material of the absorbent layer 1, which is enclosed between them and in some cases also pressed together. This improves further the rigidity of the base body 5.

Der Gegenstand weist Wirkstoffe auf. Diese liegen in Form einer Flüssigkeit vor und diese Flüssigkeit ist in mikrofeinen Gelatinkapseln 16 oder ähnlich eingeschlossen. Diese Kapseln 16 können über die Oberfläche der Deckschicht 3 verteilt sein, wo sie einem unmittelbaren Einfluss einerseits der Körperwärme und andererseits des Fussdruckes ausgesetzt sein können. Einzelne Kapseln 16 können sich ohne weiteres auch in den Aussparungen 6 befinden. Solche Kapseln 16 kommen erst später zur Abgabe ihres Inhaltes, was die Dauer der Wirksamkeit der abgegebenen Stoffe verlängert. Die Kapseln 16 können auch in der Decklage 3 oder sogar in den darunter liegenden Schichten 1 und 2 untergebracht sein. Unter der Einwirkung von Körperwärme sowie wechselnder Belastung der Schuheinlage werden die Kapseln 16 gesprengt und der Inhalt derselben wird dabei freigesetzt. Da alle Kapseln nicht sofort gesprengt werden, kann der Wirkstoff über eine längere Zeit abgegeben werden.The subject has active ingredients. These are in the form of a liquid and this liquid is enclosed in microfine gelatin capsules 16 or the like. These capsules 16 can be distributed over the surface of the cover layer 3, where they can be exposed to a direct influence on the one hand of body heat and on the other hand of foot pressure. Individual capsules 16 can also easily be located in the cutouts 6. Such capsules 16 come later to release their content, which extends the duration of effectiveness of the substances released. The capsules 16 can also be accommodated in the top layer 3 or even in the layers 1 and 2 below. Under the influence of body heat and changing loads on the shoe insert, the capsules 16 are blown up and the contents thereof are released. Since all capsules are not blown up immediately, the active ingredient can be released over a longer period of time.

Der Wirkstoff kann ein Duftstoff oder ein spezif scher Wirkstoff sein, wie zum Beispiel ein Fungizid, Antitranspirant, Bakterizid oder ähnlich.The active ingredient can be a fragrance or a specific active ingredient, such as a fungicide, antiperspirant, bactericide or the like.

Eine der Seiten bzw. Oberflächen 21 des Grundkörpers 5 des biegsamen Gegenstandes ist zur Auflage auf einer planen Fläche 17 eines zumindest im wesentlichen steifen Objektes bestimmt. Diese Seite 21 des flexiblen Gegenstandes ist mit einem nur stellen- bzw. gebietsweise angebrachten Haftvermittler bzw. Haftmedium versehen.One of the sides or surfaces 21 of the base body 5 of the flexible object is for resting on a flat surface 17 of an at least substantially rigid object. This side 21 of the flexible object is provided with an adhesion promoter or adhesive medium which is only applied in places or regions.

Das Material des Haftvermittlers bildet Inseln 25, welche in der Haftseite 21 des Grundkörpers 5 des Gegenstandes eingebettet sind. Die Inseln 25 weisen einen Sockel 26 und eine Kuppe 27 auf. Der Sockel 26 befindet sich unter der Oberfläche des Grundkörpers 5 bzw. der Stabilisationsschicht 2 und er ermöglicht eine feste Verankerung der Insel 25 im Material des Grundkörpers 5. Die Kuppe 27 ragt dagegen aus der Oberfläche der Haftseite 21 des Grundkörpers 5. Die Scheitelpartie 28 dieser Kuppe 27 ist zur Auflage auf dem Objekt 17 bestimmt und ausgebildet.The material of the adhesion promoter forms islands 25, which are embedded in the adhesive side 21 of the base body 5 of the object. The islands 25 have a base 26 and a summit 27. The base 26 is located below the surface of the base body 5 or the stabilization layer 2 and it enables the island 25 to be firmly anchored in the material of the base body 5. The dome 27, on the other hand, protrudes from the surface of the adhesive side 21 of the base body 5 Dome 27 is intended and designed to rest on object 17.

Vorteilhaft haben die Inseln 25 einen kreisförmigen Umfang. Der Durchmesser dieses Umfanges beträgt etwa 1mm oder weniger. Im vertikalen Längsschnitt können die Inseln 25 die Form einer Halbkugel oder einer Kugelkappe aufweisen. Die Höhe und die Form der Insel 25 ist so gewählt, dass sie im Material des Grundkörpers 5 gut verankert sein kann. Die halbkugelförmige oder kappenförmige Insel 25 genügt dieser Anforderung gut, weil die grösste Breite des Sockels 26 einer solchen Insel 25 im Bereich der Grundfläche 29 des Sockels 26 liegt.The islands 25 advantageously have a circular circumference. The diameter of this circumference is about 1mm or less. In the vertical longitudinal section, the islands 25 can have the shape of a hemisphere or a spherical cap. The height and shape of the island 25 is chosen so that it can be well anchored in the material of the base body 5. The hemispherical or cap-shaped island 25 meets this requirement well because the greatest width of the base 26 of such an island 25 lies in the area of the base 29 of the base 26.

Die Stabilisierungsschicht 2 kann eine Dicke von wenigen Zehnteln Millimeter haben. In einem solchen Fall kann etwa die eine Hälfte der Höhe der Halbkugel 25 den Sockel 26 und die andere Hälfte der Halbkugel, welche aus der Stabilisierungsschicht 2 ragt, die Kuppe 27 darstellen. Da die Höhe des Sockels 26 grösser ist als die Dicke der Stabilisierungsschicht 2, ist der zuunterst liegende und breiteste Abschnitt 29 des Sockels 26 sogar im Material der Saugschicht 1 eingebettet. Da die von der Grundfläche 29 abgehenden Seitenwände der Halbkugel bzw. der Kugelkappe gegen den Scheitel 28 hin zusammenlaufen, kann das Material der Saugschicht 1 und der unteren äusseren Faserschicht 2 an bzw. auf diesen Seitenwänden aufliegen und zur guten Halterung der Insel 25 im Grundkörper 5 beitragen.The stabilization layer 2 can have a thickness of a few tenths of a millimeter. In such a case, approximately one half of the height of the hemisphere 25 can represent the base 26 and the other half of the hemisphere, which protrudes from the stabilization layer 2, the tip 27. Since the height of the base 26 is greater than the thickness of the stabilizing layer 2, the lowest and widest section 29 of the base 26 is even embedded in the material of the absorbent layer 1. Since the side walls of the hemisphere or the spherical cap, which extend from the base surface 29, converge towards the apex 28, the material of the absorbent layer 1 and of the lower outer fiber layer 2 can rest on or on these side walls and for good holding of the island 25 in the base body 5 contribute.

Durch geeignete Massnahmen wird erreicht, dass das Material des Haftmediums bei der Applikation in das Material des Grundkörpers 5 so weit eindringt, dass die Verankerung dieses Haftmediums im Material des Grundkörpers 5 grösser ist als später die Haftung der Inseln 25 auf dem Objekt 17.Suitable measures ensure that the material of the adhesive medium penetrates into the material of the base body 5 so that the anchoring of this adhesive medium in the material of the base body 5 is greater than the later adhesion of the islands 25 to the object 17.

Der Haftvermittler ist aus einem Material, welches auch nach Abbindung praktisch dauerhaft klebrig bleibt, wobei dieses Material Latex enthalten kann. Die Zusammensetzung des Materials des Haftvermittlers ist so eingestellt, dass die Kohäsion im Material grösser ist als die Adhäsion dieses Materiales hinsichtlich des Materiales jenes Objektes 17, auf dem der biegsame Gegenstand 5 zum Aufliegen bestimmt ist. Das Material des Haftvermittlers kann einen Farbstoff oder/und Duftstoffe und sonstige Wirkstoffe enthalten. Das Material des Haftvermittlers 25 kann Kunststoffverbindungen, wie z.B. Nitrillatex, Acryllatex, Styrollatex usw. enthalten. Dieses Material kann dabei die Form einer Paste oder Pulver oder einer Folie haben, und es wird mit Hilfe geeigneter Technologien auf den Grundkörper 5 auf- bzw. eingebracht.The adhesion promoter is made of a material that remains practically permanently sticky even after setting, whereby this material can contain latex. The composition of the material of the adhesion promoter is set in such a way that the cohesion in the material is greater than the adhesion of this material with regard to of the material of that object 17 on which the flexible object 5 is intended to rest. The material of the adhesion promoter can contain a dye or / and fragrances and other active ingredients. The material of the adhesion promoter 25 can contain plastic compounds such as nitrile latex, acrylic latex, styrene latex, etc. This material can have the form of a paste or powder or a film, and it is applied or introduced onto the base body 5 using suitable technologies.

Eine Paste, welche zum Auftragen auf den Grundkörper 5 bestimmt ist, um die Insel an diesem Körper 5 zu bilden, hat die folgende Zusammensetzung:

  • 850 Teile Nitrillatex-Dispersion 45 %ig
  • 18 Teile emulgiertes Weissöl, nichtionisch
  • 45 Teile Acrylsäureester 55 %ig
  • 45 Teile Acrylsäure 25 %ig
  • 42 Teile Ammoniak und Wasser.
A paste which is intended for application to the base body 5 in order to form the island on this body 5 has the following composition:
  • 850 parts of 45% nitrile latex dispersion
  • 18 parts of emulsified white oil, non-ionic
  • 45 parts of 55% acrylic ester
  • 45 parts of 25% acrylic acid
  • 42 parts of ammonia and water.

Diese Mischung ergibt eine Paste mit etwa 10 bis 11 Pas (100 bis 110 Poise) Viskosität, welche mit Hilfe einer Schablonendruckmaschine als Muster auf den Grundkörper 5 gedruckt wird. Nach dem Trocknen bei etwa 140 Grad Celsius wird das Wasser der Paste verdampft und es bleibt ein Raster aus leicht klebrigen Inseln 25 übrig. Diese Inseln 25 stellen den eigentlichen Haftvermittler dar.This mixture results in a paste with a viscosity of about 10 to 11 Pas (100 to 110 poise), which is printed as a pattern on the base body 5 using a stencil printing machine. After drying at about 140 degrees Celsius, the water of the paste is evaporated and a grid of slightly sticky islands 25 remains. These islands 25 represent the actual adhesion promoter.

Die Verteilung der Inseln 25 aus dem Haftmaterial über die Fläche des Grundkörpers 5 kann unter der Anwendung eines Komputers derart berechnet werden, dass sie für den jeweiligen Einsatz richtig ist. Dies ist deswegen möglich, weil das Haftmaterial Punkte oder nur kleine Bezirke, Inseln 25, bildet. Mit Hilfe einer Berechnung lässt sich die Intensität der Haftung des Gegenstandes 5 auf einem Objekt 17 durch eine passende Wahl der Anzahl der Inseln 25 je Flächeneinheit des Grundkörpers 5 entsprechend dem jeweiligen Zweck genau einstellen. Dies war bisher nicht möglich, weil die Haftfläche mit dem Material eines Haftvermittlers zusammenhängend bedeckt war. Einz Aenderung der Haftfähigkeit war somit nur durch Variationen des Haftmaterials möglich, was sehr umständlich war. Im vorliegenden Fall muss das Material des Haftvermittlers nicht geändert werden, sondern es genügt gemäss der vorliegenden Erfindung, die Anzahl oder/und die Grösse der Inseln 25 zu ändern. Solche Aenderungen lassen sich in der betreffenden Druckmaschine problemlos durchführen. Ausserdem ermöglichen die Inseln 25, unterschiedliche Haftfähigkeiten in bestimmten Gebieten desselben Gegenstandes zu erreichen, was bisher ebenfalls nicht möglich war.The distribution of the islands 25 from the adhesive material over the surface of the base body 5 can be calculated using a computer in such a way that it is correct for the respective application. This is possible because the adhesive material forms points or only small areas, islands 25. With the help of a calculation, the intensity of the adhesion of the object 5 to an object 17 can be set precisely by a suitable choice of the number of islands 25 per unit area of the base body 5 according to the respective purpose. This was previously not possible because the adhesive surface was covered with the material of an adhesion promoter. The only change in the adhesiveness was possible only through variations of the adhesive material, which was very cumbersome. In the present case, the material of the bonding agent does not have to be changed, but it is sufficient according to the present invention to change the number and / or the size of the islands 25. Such changes can be carried out without any problems in the printing press in question. In addition, the islands 25 make it possible to achieve different adhesive strengths in certain areas of the same object, which was also not previously possible.

Der in Fig. 1 perspektivisch dargestellte biegsame Gegenstand weist die mittlere Schicht 1, die untere Schicht 2 sowie die Deckschicht 3 der Sohle nach Fig. 2 auf. Die Unterseite der zweiten bzw. unteren Schicht 2, welche dünner ist als die erste Schicht 1, ist mit den beschriebenen Inseln 25 versehen. Ein solcher Grundkörper 5 ist mit den ebenfalls bereits beschriebenen Aussparungen 6 versehen. Diese Aussparungen 6 sind als Löcher 8 ausgeführt, welche durch alle drei Schichten 1 bis 3 hindurchgehen. Es versteht sich jedoch, dass diese Aussparungen 6 auch nur als Vertiefungen 7 ausgeführt sein können oder dass ein solcher Grundkörper 5 sowohl Vertiefungen 7 als auch Löcher 8 aufweisen kann.The flexible object shown in perspective in FIG. 1 has the middle layer 1, the lower layer 2 and the Cover layer 3 of the sole according to FIG. 2. The underside of the second or lower layer 2, which is thinner than the first layer 1, is provided with the islands 25 described. Such a base body 5 is provided with the cutouts 6, which have also been described. These recesses 6 are designed as holes 8 which pass through all three layers 1 to 3. However, it goes without saying that these cutouts 6 can also be designed only as depressions 7 or that such a base body 5 can have both depressions 7 and holes 8.

Der Gegenstand weist eine ganze Anzahl von Aussparungen 6 auf, welche Muster bilden. In Fig. 1 und 3 ist ein Muster dargestellt, welches zwei Arten von Aussparungen 6, eigentlich Löcher 8, enthält. Die beiden Arten der Aussparurgen 6 haben einen rechteckigen Querschnitt. Die Länge der ersten Aussparungen 61 ist kleiner als die Länge der zweiten Aussparungen 62. Die Breite der Aussparungen 61 und 62 der beiden Arten ist etwa gleich gross.The object has a whole number of cutouts 6, which form patterns. 1 and 3 a pattern is shown which contains two types of recesses 6, actually holes 8. The two types of recesses 6 have a rectangular cross section. The length of the first recesses 61 is smaller than the length of the second recesses 62. The width of the recesses 61 and 62 of the two types is approximately the same.

Die längeren Aussparungen 62 bilden parallel zueinander verlaufende Reihen 32 im Grundkörper 5, welche sich in einem Abstand voneinander befinden. Die Aussparungen 62 in der jeweiligen Reihe 32 sind so orientiert, dass die längeren Seiten 33 derselben parallel zueinander verlaufen. Der Abstand zwischen zwei nebeneinander liegenden Aussparungen 62 ist grösser als die kürzere Seite 34 der Aussparung 62. Die Aussparungen 62 in den benachbarten Reihen 32 sind zueinander versetzt angeordnet, derart, dass eine der Aussparungen 62 der einen Reihe 32 praktisch in der Mitte des Abstandes zwischen zwei benachbarten Aussparungen 62 der benachbarten Reihe 32 liegt.The longer cutouts 62 form parallel rows 32 in the base body 5, which are at a distance from one another. The cutouts 62 in the respective row 32 are oriented such that the longer sides 33 thereof run parallel to one another. The distance between two Recesses 62 lying next to one another are larger than the shorter side 34 of the cutout 62. The cutouts 62 in the adjacent rows 32 are arranged offset to one another such that one of the cutouts 62 of the one row 32 is practically in the middle of the distance between two adjacent cutouts 62 the adjacent row 32.

Die kürzeren Aussparungen 62 bilden ebenfalls parallel zueinander verlaufende Reihen 35, welche sich in einem Abstand voneinander befinden. Jeweils eine dieser Reihen 35 liegt zwischen zwei Reihen 32 mit den längeren Aussparungen 62, so dass diese zwei Arten von Reihen 32 und 35 miteinander abwechseln. Die längeren Seiten der kürzeren Aussparungen 61 liegen schräg zur Längsachse L der jeweiligen Reihe, wobei die Längsseiten mit der Längsachse L der Reihe 35 unterschidliche Winkel schliessen. Es gibt zwei Arten dieser kürzeren Aussparungen. Bei den ersten Aussparungen 611 beträgt der Winkel zwischen der Längsseite derselben und der Längsachse L dieser Reihe 135 Grad. Bei den zweiten Aussparungen 612 beträgt der Winkel wischen der Längsseite der Aussparung 612 und der Längsachse L nur 45 Grad. Zwischen zwei Aussparungen der ersten Art, z.B. von 611, liegt jeweils eine Aussparung der zweiten Art, d.h. 612, so dass diese zwei Arten von Aussparungen 611 und 612 miteinander abwechseln.The shorter recesses 62 likewise form rows 35 which run parallel to one another and are at a distance from one another. In each case one of these rows 35 lies between two rows 32 with the longer recesses 62, so that these two types of rows 32 and 35 alternate with one another. The longer sides of the shorter recesses 61 lie obliquely to the longitudinal axis L of the respective row, the longitudinal sides closing different angles with the longitudinal axis L of the row 35. There are two types of these shorter recesses. In the case of the first cutouts 611, the angle between the longitudinal side thereof and the longitudinal axis L of this row is 135 degrees. In the case of the second recesses 612, the angle between the longitudinal side of the recess 612 and the longitudinal axis L is only 45 degrees. Between two cutouts of the first type, for example 611, there is a cutout of the second type, ie 612, so that these two types of cutouts 611 and 612 alternate with one another.

Die kürzeren Aussparungen 611 und 612 einer Reihe 35 sind in bezug auf die längeren Aussparungen 62 der zwei unmittelbar benachbarten Reihen 32 derart orientiert und angeordnet, dass die Längsseiten der kürzeren Aussparungen 611 und 612 parallel zu einer Linie verlaufen, welche die Endpartien der versetzt zueinander angeordneten längeren Aussparungen 612 der benachbarten Reihen 32 verbindet.The shorter recesses 611 and 612 of a row 35 are oriented and arranged with respect to the longer recesses 62 of the two immediately adjacent rows 32 such that the long sides of the shorter recesses 611 and 612 run parallel to a line which the end parts of the staggered to each other connects longer recesses 612 of the adjacent rows 32.

Den einen Endpartien zweier zueinander benachbarten, längeren Aussparungen 62 in einer der benachbarten Reihe 32 sind jeweils zwei kürzere Aussparungen 611 und 612 der Reihe 35 einerends zugeordnet, welche mit zunehmenden Abstand von den längeren Aussparungen 62 zusammenlaufen. Die einander näher liegenden Endpartien dieser kürzeren Aussparungen 611 und 612 sind dann einem Ende einer der längeren Aussparungen 62 aus der Reihe 32 dieser zugeordnet, welche an der anderen Seite der Reihe 35 mit diesen kürzeren Aussparungen 611 und 612 liegt. In dieser Weise entstehen bei der Betrachtung eines solchen Gegenstandes sechseckförmige Muster, in welchen zwei nebeneinander liegende, längere und rechteckförmige Aussparungen 62 zwei längere Seiten eines Sechseckes bilden. Je ein Paar zusammenlautender und kürzerer Aussparungen 611 und 612 ist den Endpartien- dieser längeren Aussparungen 62 zugeordnet.One end part of two mutually adjacent, longer cutouts 62 in one of the adjacent row 32 are each assigned two shorter cutouts 611 and 612 of the row 35 at one end, which converge with increasing distance from the longer cutouts 62. The end portions of these shorter recesses 611 and 612 which are closer to one another are then assigned to one end of one of the longer recesses 62 from the row 32 which lies on the other side of the row 35 with these shorter recesses 611 and 612. In this way, when viewing such an object, hexagonal patterns are formed in which two adjacent, longer and rectangular cutouts 62 form two longer sides of a hexagon. A pair of concurrent and shorter recesses 611 and 612 is assigned to the end parts of these longer recesses 62.

Ein wichtiges Merkmal der vorliegenden Erfindung beruht darin, dass die Inseln 25 aus einem Haftmaterial an der Unterseite des Gegenstandes sich nur in jenen Bereichen des Grundkörpers 5 befinden, welche zwischen benachbarten Aussparungen 6 im Grundkörper 5 liegen. Dies zeigt Fig. 3, in welcher ein Ausschnitt aus dem Gegenstand gemäss Fig. 1 in Draufsicht abgebildet ist.An important feature of the present invention resides in that the islands 25 made of an adhesive material on the underside of the object are located only in those areas of the base body 5 which lie between adjacent cutouts 6 in the base body 5. This is shown in FIG. 3, in which a section of the object according to FIG. 1 is shown in a top view.

Das mit Haftmedium 25 versehene Material 5 ist nur partiell bedeckt. Der Grundkörper des Gegenstandes bleibt daher für Luft und Feuchtigkeit durchlässig, falls er dies vorher war.The material 5 provided with adhesive medium 25 is only partially covered. The base body of the object therefore remains permeable to air and moisture if it was previously.
