The method is for producing watertight footwear containing an outer leg (1), to the lower end of which an insole (3) is sewn and a watertight, water-vapor-permeable inner leg (2), which in the sole area has an inwardly turned-over end area. The insole, in an area corresponding to the end area of the inner leg, is provided with a layer (4a) of activatable adhesive. The end area of the inner leg is sewn (5) to the insole. The outer leg is then positioned to encase the inner leg. The end area of the inner leg is positioned so that with the insole and the outer leg a hollow space is enclosed. The lower end of the outer leg is then sewn (6) to the outer edge of the insole. Finally, the adhesive layer (4a) is activated and the end area of the inner leg is pressed against the insole.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Schuhwerkes enthaltend einen Außenschaft, welcher an seinem unteren Ende mit einer Brandsohle vernäht ist, und einen eine wasserdichte, wasserdampfdurchlässige Funktionsschicht und ein Futter enthaltenden Innenschaft, welcher im Sohlenbereich einen nach innen umgeschlagenen Endbereich aufweist, welcher Endbereich mit der Brandsohle wasserdicht verbunden ist und eine Umlaufkante aufweist, die eine Öffnung umschließt. Die Erfindung betrifft auch ein Schuhwerk, welches die genannten Merkmale aufweist.The invention relates to a method for producing a footwear containing an outer shaft, which is sewn at its lower end with an insole, and a waterproof, water vapor permeable functional layer and lining containing inner shaft, which in the sole area one inside has turned end region, which end region with the insole is watertight connected and has a peripheral edge which encloses an opening. The invention also relates to a footwear which has the mentioned features.

Ein derartiges Herstellverfahren und ein derartiges Schuhwerk ist in DE 44 19 802 A1 beschrieben. Bei dem dort beschriebenen Herstellverfahren, kann die Nähverbindung, mit welcher der Außenschaft mit der dort als Zwischenschicht bezeichneten Brandsohle nur sehr schwierig ausgeführt werden, weil durch das Ankleben des Endbereichs des Innenschaftes an die Zwischenschicht der untere Bereich des Innenschaftes eng an dem Außenschaft anliegt, so dass beim Annähen des Außenschaftes an die Zwischenschicht häufig der Innenschaft und somit auch die wasserdampfdurchlässige, wasserdichte Funktionsschicht von der Nähnadel beschädigt wird. Als Folge davon ist ein derart hergestelltes Schuhwerk nicht mehr wasserdicht.Such a manufacturing method and such footwear is described in DE 44 19 802 A1 described. In the case of the production method described there, the sewing connection, with which the outer shaft with there referred to as an intermediate layer insole be carried out very difficult, because by sticking the end of the Inner shaft to the intermediate layer of the lower portion of the inner shaft closely abuts the outer shaft, so that when sewing the outer shaft to the Intermediate layer often the inner shaft and thus also the water vapor permeable, waterproof functional layer is damaged by the sewing needle. As a result of this is a footwear made in this way is no longer waterproof.

Das Dokument WO-A-0112002 offenbart ein Schuhwerk mit einem Schaft, der mindestens teilweise mit einer wasserdichten Funktionsschicht versehen ist, die vorzugsweise wasserdampfdurchlässig ist und mit einer Laufsohle sowie ein Verfahren zur Herstellung eines solchen Schuhwerkes. Die Laufsohle dieses Schuhwerks ist mit dem Schaftendbereich verbunden und der Funktionsschichtendbereich, der einen nicht vom Obermaterial überdeckten Randbereich aufweist, ist in diesem Bereich mit einer in Laufsohlenumfangsrichtung geschlossenen Klebstoffzone versehen, die zu Wasserdichtigkeit führt. Die Herstellung dieses Schuhwerkes ist jedoch relativ aufwändig und verursacht damit zu hohe Herstellungskosten.The document WO-A-0112002 discloses a footwear with a shaft which is at least partially provided with a waterproof functional layer, the preferably permeable to water vapor and having an outsole and a method for producing such footwear. The outsole of this shoe is with the Schaftendbereich connected and the Funktionsschichtendbereich, the one not covered by the upper edge area is in this area with an in Outsole circumferential direction closed adhesive zone provided to Waterproofness leads. However, the production of this footwear is relative consuming and thus causes too high production costs.

The object of the invention is achieved by a method for producing a footwear comprising an outer shaft which is sewn at its lower end with an insole, and a waterproof, water vapor permeable functional layer and a lining containing inner shaft, which in the sole region an inwardly folded end region which end region is watertightly connected to the insole and has a peripheral edge which encloses an opening, which is characterized by the following steps:
  • Producing an outer shaft whose end towards the sole side has a contour which corresponds at least approximately to the outer contour of the insole,
  • Producing a feed shaft which has at least one lining arranged on the inside and a functional layer, which feed shaft has an inwardly turned-over end region on the sole side, which end region has a peripheral edge which encloses an opening,
  • Providing an insole provided with a layer of activatable adhesive at least in a region corresponding to the end region of the inner shaft,
  • Placing the inner shaft on the insole so that the end portion of the inner shaft rests on the insole,
  • Sewing the end region of the inner shaft with the insole along the circumferential edge of the end region of the inner shaft,
  • Placing the outer shaft in such a way that the outer shaft encloses the inner shaft,
  • Invagination of the end portion of the inner shaft such that the end portion of the inner shaft encloses a cavity with the insole and the outer shaft,
  • Sewing the lower end of the outer shaft to the outer edge of the insole,
  • Applying the end portion of the inner shaft to the insole,
  • Activate the adhesive of the layer on the insole and
  • Pressing the end of the inner shaft with the insole, creating a watertight connection between the end of the inner shaft and the insole.

Durch die Verwendung eines aktivierbaren Klebers wird es möglich, zunächst die Außenschicht mit der Brandsohle zu vernähen, bevor der Endbereich des Innenschaftes mit der Brandsohle verklebt wird. Nur dadurch, dass der Endbereich des Innenschaftes noch nicht mit der Brandsohle verklebt ist, wird es möglich den unteren Bereich des Innenschaftes nach innen zu stülpen, um ihn aus dem Gefahrenbereich der durch den Außenschaft stechenden Nadel zu verlagern. Durch die vorher mit der Brandsohle vernähte Endkante des Endbereichs des Innenschaftes, wird es möglich, nach erfolgter Vernähung des Außenschaftes mit der Brandsohle den Innenschaft frei von Falten an den Außenschaft und den Endbereich des Innenschaft frei von Falten an die Brandsohle, beispielsweise durch Einführen eines Leisten, anzulegen. Die auf der Brandsohle befindliche Schicht aus aktivierbarem Kleber kann dann aktiviert werden, wonach die wasserdichte Verbindung zwischen Brandsohle und Endbereich des Innenschaftes über den aktivierten Kleber und vorzugsweise unter Druck bewerkstelligt wird.By using an activatable adhesive, it is possible, first the Sew the outer layer with the insole before the end of the Inner shaft is glued to the insole. Only in that the end of the Inner shaft is not yet glued to the insole, it becomes possible the lower To push inside the inner shaft to the inside of it, to remove it from the danger area to relocate through the outer shaft stinging needle. By the previously with the Insole stitched end edge of the end portion of the inner shaft, it becomes possible After sewing the outer shaft with the insole, the inner shaft free of wrinkles on the outer shaft and the end portion of the inner shaft free of wrinkles to put on the insole, for example by inserting a last. The on the Insole layer of activatable adhesive can then be activated, according to which the watertight connection between insole and end region of the Inner shaft over the activated adhesive and preferably accomplished under pressure becomes.

Das Vernähen des Endbereichs des Innenschaftes mit der Brandsohle entlang der Umlaufkante des Endbereichs des Innenschaftes erfolgt in der Regel direkt oder nur wenige Millimeter neben der Umlaufkante des Endbereichs, um für die wasserdichte Verklebung zwischen Endbereich des Innenschaftes und Brandsohle eine Fläche zur Verfügung zu stellen, die breit genug ist, um ein Eindringen von Wasser wirksam zu vermeiden. Um das Annähen des Endbereichs des Innenschaftes zu vereinfachen, ist es zweckmäßig, auf der Brandsohle die Kontur zu markieren, entlang welcher die Umlaufkante des Endbereichs des Innenschaftes angenäht werden soll. Bevorzugt ist die Brandsohle derart ausgebildet, dass sie in dem Bereich, auf dem der Endbereich des Innenschaftes aufgelegt werden soll etwas vertieft ausgebildet ist. Durch diese Vertiefung ergibt sich auf der Brandsohle eine Umlaufkante an die die Umlaufkante des Endbereichs des Innenschaftes angeschlagen werden kann, bevor der Endbereich des Innenschaftes vernäht wird. Die Umlaufkante der Brandsohle hat auch den Vorteil, dass beim Aufbringen der Schicht des aktivierbaren Klebers auf die Brandsohle der Bereich für diese Schicht festgelegt ist, sodass der für die wasserdichte Verbindung zwischen Endbereich des Innenschaftes und der Brandsohle deutlich definiert ist. Die Vertiefung hat außerdem den Vorteil, dass diese Vertiefung bis zu einer solchen Tiefe ausgeführt werden kann, dass nach erfolgter Verklebung des Endbereiches des Innenschaftes mit der Brandsohle in Innenbereich des Schuhwerkes der Endbereich des Innenschaftes mit dem freien Teil der Brandsohle eine stete Fläche bildet, so dass in vielen Fällen bei dem erfindungsgemäßen Schuhwerke auf eine zusätzliche Einlegesohle verzichtet werden kann, ohne den Komfort für den Träger des Schuhwerkes zu beeinträchtigen.Sewing the end of the inner shaft with the insole along the Circumferential edge of the end portion of the inner shaft is usually directly or only a few millimeters next to the peripheral edge of the end, in order for the waterproof Bonding between end portion of the inner shaft and insole a surface for Provide that is wide enough to effectively prevent ingress of water avoid. To facilitate the sewing of the end portion of the inner shaft is it is expedient to mark on the insole the contour along which the Circumferential edge of the end portion of the inner shaft to be sewn. Is preferred the insole is designed so that it is in the area on which the end the inner shaft should be placed a little deepened. Through this Deepening results on the insole a peripheral edge to the peripheral edge of the End portion of the inner shaft can be struck before the end of the Inner shaft is sewn. The peripheral edge of the insole also has the advantage that when applying the layer of activatable adhesive on the insole of the area is set for this layer, allowing for the waterproof connection between End area of the inner shaft and the insole is clearly defined. The depression also has the advantage that this depression is carried out to such a depth can be that after the bonding of the end portion of the inner shaft with the insole in the inner area of the footwear the end area of the inner shaft with the free part of the insole forms a constant surface, so that in many cases at the footwear according to the invention waives an additional insole can be without compromising the comfort for the wearer of the footwear.

Bei dem erfindungsgemäßen Verfahren hat es sich als besonders günstig herausgestellt, wenn vor dem Aufsetzen des Innenschaftes auf die Brandsohle der Endbereich des Innenschaftes mit einer Schicht eines aktivierbaren Klebers versehen wird. Auf diese Weise steht sowohl auf der Brandsohle als auch auf dem Endbereich des Innenschaftes ein aktivierbarer Kleber zur Verfügung, so dass die durch die zu bewerkstelligende Verklebung geforderte Wasserdichtigkeit besonders einfach zu gewährleisten ist.In the method according to the invention, it has proved to be particularly favorable exposed, if before putting the inner shaft on the insole of the End region of the inner shaft provided with a layer of activatable adhesive becomes. In this way stands both on the insole as well as on the end area of the inner shaft an activatable adhesive available, so that by the to completing bonding required water resistance particularly easy to ensure.

Auch hat es sich als Vorteil herausgestellt, wenn als Brandsohle eine wasserdicht ausgestattete Brandsohle bereitgestellt wird. Die wasserdichte Ausstattung der Brandsohle kann im einfachsten Fall durch eine auf der zur Fußseite hin gelegenen Oberfläche der Brandsohle aufgebrachte wasserdichte Schicht, die aus einem wasserdichten Polymer oder auch aus einer wasserdichten wasserdampfdurchlässigen Funktionsschicht besteht, bewerkstelligt werden. Die wasserdichte Ausrüstung der Brandsohle kann aber auch darin bestehen, dass die Brandsohle an sich, zumindest in dem dem Endbereich des Innenschaftes entsprechenden Bereich oder auch vollständig aus einem wasserdichten Material besteht.Also, it has turned out to be an advantage if a waterproof as an insole equipped insole is provided. The waterproof features of the Insole can in the simplest case by a lying on the foot side Surface of the insole applied waterproof layer, which consists of a waterproof polymer or even a waterproof, water vapor permeable Function layer exists, be accomplished. The waterproof equipment of But insole can also consist in that the insole itself, at least in the area corresponding to the end portion of the inner shaft or even completely made of a waterproof material.

Besonders vorteilhaft für das erfindungsgemäße Verfahren hat es sich herausgestellt, wenn für die Schicht auf der Brandsohle und/oder für die Schicht auf dem Endbereich des Innenschaftes ein aktivierbarer Kleber eingesetzt wird, der infolge von Hitze aktivierbar ist. Particularly advantageous for the method according to the invention, it has been found if for the layer on the insole and / or for the layer on the end area of the inner shaft an activatable adhesive is used, due to heat is activatable.

In der Regel wird ein Schuhwerk, insbesondere dann, wenn der Außenschaft aus Leder oder aus einem Leder ähnlichen Material besteht, nach dem Vernähen des Außenschaftes mit der Brandsohle und nach Einsetzen des Leistens in heißer Luft erhitzt, wodurch sich der Außenschaft an die von der Kontur des Brandsohle und an die Form des Leistens anpasst. Die hierfür erforderlich Hitze reicht in der Regel aus, um den über Hitze aktivierbaren Kleber in klebrigen Zustand zu versetzen, wonach das Schuhwerk mit dem Leisten direkt nach der Hitzebeaufschlagung in eine Presse eingesetzt werden kann, wodurch durch den in der Presse eingestellten Druck die wasserdichte Verbindung zwischen Endbereich des Innenschaftes und der Brandsohle erreicht werden kann.In general, a footwear, especially if the outer shaft of leather or of a leather-like material, after sewing the Outer shaft with the insole and after inserting the last in hot air heated, causing the outer shaft to the from the contour of the insole and to the Shape of the last fits. The heat required for this is usually sufficient to to put the heat activatable adhesive in sticky state, after which the Footwear with the last directly after the heat in a press can be used, whereby by the pressure set in the press the waterproof connection between the end of the inner shaft and the insole can be achieved.

Das Anlegen des Innenschaftes an den Außenschaft und des Endbereichs des Innenschaftes an die Brandsohle kann im einfachsten Fall mit der Hand geschehen. Aufgrund dessen, dass die Umlaufkante des Endbereichs des Innenschaftes über die Naht mit der Brandsohle fixiert ist, hat sich herausgestellt, dass eine Einführung des Leistens in den Schuh ausreicht, den Innenschaft an den Außenschaft und den Endbereich des Innenschaftes an die Brandsohle, ohne Falten zu bilden, anzulegen. Insofern zeichnet sich das erfindungsgemäße Verfahren insbesondere dadurch aus, dass zum Anlegen des Endbereichs des Innenschaftes ein Leisten in das Schuhwerk eingeführt wird.The application of the inner shaft to the outer shaft and the end of the Inner shaft to the insole can be done by hand in the simplest case. Due to the fact that the peripheral edge of the end portion of the inner shaft over the Suture is fixed with the insole, it has been found that an introduction of the Lining in the shoe is sufficient, the inner shaft to the outer shaft and the End area of the inner shaft to the insole, without forming folds, create. In this respect, the method according to the invention is characterized in particular by that for applying the end portion of the inner shaft a last in the footwear is introduced.

Die erfindungsgemäß gestellte Aufgabe wird auch gelöst durch ein Schuhwerk, enthaltend einen Außenschaft, welcher an seinem unteren Ende unmittelbar mit einer Brandsohle vernäht ist, und einen eine wasserdichte, wasserdampfdurchlässige Funktionsschicht und ein Futter enthaltenden Innenschaft, welcher im Sohlenbereich einen nach innen umgeschlagenen Endbereich aufweist, welcher Endbereich mit der Brandsohle wasserdicht verbunden ist und eine Umlaufkante aufweist, die eine Öffnung umschließt, dadurch gekennzeichnet, dass der Endbereich des Innenschaftes entlang der Umlaufkante mit der Brandsohle vernäht ist. Wie die obigen Ausführungen gezeigt haben, ist ein derartiges Schuhwerk besonders einfach herstellbar, ohne dass durch dieses einfache Herstellverfahren die Wasserdichtigkeit der wasserdichten, wasserdampfdurchlässigen Funktionsschicht und der Komfort für den Träger des erfindungsgemäßen Schuhwerkes, beispielsweise infolge von Faltenbildung des Futterschaftes, beeinträchtigt wird.The object of the invention is also achieved by a footwear, containing an outer shaft, which at its lower end directly with a Insole is sewn, and a waterproof, water vapor permeable Functional layer and a lining containing inner shaft, which in the sole area having an inwardly folded end portion, which end portion with the Insole is waterproof and has a peripheral edge, which has an opening encloses, characterized in that the end portion of the inner shaft along the peripheral edge is sewn to the insole. As shown above have such a footwear is particularly easy to produce, without passing through this simple manufacturing process makes the watertightness of waterproof, vapor permeable functional layer and comfort for the wearer of the footwear according to the invention, for example due to wrinkling of the Fodder shaft, is impaired.

Das erfindungsgemäße Schuhwerk zeichnet sich insbesondere dadurch aus, dass die Brandsohle eine umlaufende Vertiefung aufweist, auf der der Endbereich des Innenschaftes aufliegt, und die Vertiefung der Brandsohle derart ausgebildet ist, dass auf der Schuhwerkinnenseite der Endbereich des Innenschaftes mit der Brandsohle eine stete Fläche bildet.The footwear according to the invention is characterized in particular by the fact that the Insole has a circumferential recess on which the end of the Inner shaft rests, and the recess of the insole is designed such that on the inside of the footwear the end area of the inner shaft with the insole forms a continuous surface.
