Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Einspannen eines flachen Schuhoberteilwerkstücks, die mit einer Versteifungsschicht aus thermoplastischem Material zu versehen ist.The invention relates to a device for clamping a flat shoe upper workpiece which is to be provided with a stiffening layer made of thermoplastic material.

Es ist bekannt, das Auftragen einer solchen Versteifungsschicht mit einem Pinsel vorzunehmen (s. Textbook of Footwear Material, The National Trade Press Ltd., London 1955, Seite 365). Diese Methode des Auftragens ist einerseits für eine moderne Massenfabrikation völlig ungeeignet, andererseits entsteht dabei das Problem, daß bestimmte, notwendige Konturen für die Versteifungsschicht schlecht eingehalten werden können. It is known to apply such a stiffening layer with a brush (see Sect. Textbook of Footwear Material, The National Trade Press Ltd., London 1955, p. 365). This method of On the one hand, application is completely unsuitable for modern mass production; on the other hand, this is what happens Problem that certain, necessary contours for the stiffening layer can be poorly maintained.

Es ist darüber hinaus aus der US-PS 20 60 616 bekannt, auf eine Folie od. dgl. an bestimmten Stellen einen Klebstoff aufzutragen, wozu die Folie gegen eine Platte gesaugt wird, die mit Löchern versehen ist, an die eine Unterdruckquelle angeschlossen ist. Durch den Unterdruck wird dann die Folie fest an der Platte gehalten. Die Platte ist mit erhabenen Stellen versehen, so daß sich entsprechend dieser Formgebung der Platte erhabene Bereiche der Folie ergeben, auf die dann der Klebstoff maschinell aufgetragen werden kann, ohne daß die niedriger liegenden Bereiche in den Klebstoffauftrag einbezogen werden. Dieses Verfahren ist im Rahmen der Schuhherstellung als Massenfabrikation ungeeignet, da es wegen der speziell geformten und gelochten Platten zusammen mit der Unterdruckquelle einen erheblichen Aufwand darstellt. Sowohl bei porösem Material als auch bei relativ dickem Material für ein Schuhoberteilwerkstück, insbesondere bei relativ dickem Leder, kann auch nicht dafür garantiert werden, daß sich dieses wegen seiner Steifigkeit voll einer mit erhabenen Zonen versehenen Platte nur unter der Wirkung des Unterdrucks im Bereich zwischen den erhabenen Zonen anpaßt, so daß nicht sichergestellt sein würde, daß wirklich nur die gewünschten Zonen mit der Versteifungsschicht versehen werden wurden.It is also known from US Pat. No. 20 60 616, on a film or the like at certain points To apply an adhesive, for which purpose the film is sucked against a plate which is provided with holes to which a vacuum source is connected. Due to the negative pressure, the film is then firmly attached to the plate held. The plate is provided with raised areas, so that the plate is shaped accordingly result in raised areas of the film to which the adhesive can then be applied by machine without that the lower lying areas are included in the adhesive application. This procedure is in Frame of shoe production unsuitable as mass production, because it is because of the specially shaped and perforated plates together with the vacuum source represents a considerable effort. Both at porous material as well as with relatively thick material for a shoe upper workpiece, especially with relatively thick leather, it cannot be guaranteed that it will be full of leather because of its stiffness raised zones provided plate only under the effect of the negative pressure in the area between the raised zones so that it would not be guaranteed that only the desired zones with the stiffening layer.

Dabei muß die Folie mit erheblichem Druck zwischen den beiden Teilen der Form eingespannt sein, damit beim Spritzen keinIt is further known from DE-PS 8 33 118 is known in a process for the production of molded articles made of thermoplastic materials with the same kind \ olienüberzug a film initially / wipe the upper and the lower part of a two-part fuel / form nip and then into the interior of the fuel / form to inject the plastic, which fills the interior of the form and rests against the film, which is pressed against the wall of one part of the form. The film must be clamped between the two parts of the mold with considerable pressure, so that no

Diese Art des Auftragens einer Versteifungsschicht ist für Schuhoberteile ungeeignet, da diese durch das Zusammenpressen der beiden Formteile auf der später nach außen weisenden Seite Druckstellen erhalten• 5 plastic can flow out of the side of the mold. This is the way of applying a stiffening layer unsuitable for shoe uppers, as this is caused by the pressing of the two molded parts on the later outward-facing side has bruises

ίο wurden, die das Aussehen eines derartigen Schuhoberteils so beeinträchtigen würden, daß es für die Schuhherstellung nicht mehr brauchbar wäre.ίο were that the appearance of such a shoe upper would be so impaired that it would no longer be usable for shoe manufacture.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, bei der nur bestimmte Bereiche des Schuhoberteilwerkstücks mit der Versteifungsschicht versehen werden, die mit geringem technischen Aufwand auskommt und bei der sichergestellt ist, daß die später außen liegende Seite des Schuhoberteilwerkstücks in seinem Aussehen nicht beeinträchtigt werden kann. Gelöst wird das Problem durch eine Vorrichtung, die dadurch gekennzeichnet ist, daß eine nachgiebige Werkstückunterlage, die eine der Form des zu beschichtenden Bereichs des Werkstücks entsprechende, erhöhte Oberfläche aufweist, auf einem Träger liegt, dem gegenüberliegend eine Klemmplatte mit einer ebenfalls der Form der zu beschichtenden Fläche des Werkstücks entsprechenden Ausnehmung angeordnet ist, und daß Verschiebungsmittel vorgesehen sind, durch die der Träger und die Klemmplatte zum Einspannen und Verformen des Werkstücks für das Auftragen der Versteifungsschicht gegeneinander preßbar sind.The invention is based on the object of providing a device of the type described at the outset create in which only certain areas of the shoe upper workpiece are provided with the stiffening layer which gets by with little technical effort and which ensures that the later outer side of the shoe upper workpiece can not be impaired in its appearance. The problem is solved by a device which is characterized in that a compliant Workpiece support that corresponds to the shape of the area of the workpiece to be coated, Has increased surface, lies on a carrier, opposite to which a clamping plate with a also the shape of the surface to be coated of the workpiece is arranged corresponding to the recess is, and that displacement means are provided by which the carrier and the clamping plate for clamping and deforming the workpiece can be pressed against one another for the application of the stiffening layer.

Die erfindungsgemäße Vorrichtung kommt im wesentlichen mit zwei Bauteilen aus, nämlich derThe device according to the invention comes from essentially with two components, namely the

J5 nachgiebigen Werkstückunterlage und der Klemmplatte, wobei beide Teile noch im zu beschichtenden Bereich des zwischen sie einzuspannenden Werkstücks entsprechend geformt sind. Dabei kommt es auf eine besonders genaue Formgebung der Klemmplatte nicht an, da Ungleichmäßigkeiten ohne weiteres durch die nachgiebige Werkstückunterlage ausgeglichen werden können. Die nachgiebige Werkstückunterlage sorgt, darüber hinaus dafür, daß die ihr zugewandte Seite des Schuhoberteilwerkstücks beim Zusammentreffen von Klemmplatte und Werkstückunterlage nicht beschädigt werden kann. Die nachgiebige Werkstückunterlage kann den von ihr auf das Schuhoberteilwerkstück ausgeübten Druck so ausgleichen, daß es zu keinen Druckstellen kommt. Dabei ist der Werkstückunterlage die später außen liegende Seite des Schuhoberteilwerkstücks zugewandt,. da dessen andere Seite mit der Versteifungsschicht :zu versehen ist. Die nachgiebige Werkstückunterlage und die Klemmplatte sorgen dafür, daß sich ein dazwischenliegendes Schuhoberteilwerkstück im Bereich der erhabenen Oberfläche der Werkstückunterlage und der inneren Umrandung der Klemmplatte hochgewölbt, wobei dieses Hochwölben durch das Zusammenpressen von Klemmplatte und Werkstückunterlage unterstützt wird. Es bildet sich somit ein hochgewölbter Bereich des Schuhoberteilwerkstücks aus, auf das allein die Versteifungsschicht aufgetragen werden kann.J5 flexible workpiece support and the clamping plate, with both parts still in the area to be coated of the workpiece to be clamped between them accordingly are shaped. A particularly precise shape of the clamping plate is not important here, since Irregularities can easily be compensated for by the flexible workpiece support. The resilient workpiece support also ensures that the side of the facing it The upper part of the shoe is not damaged when the clamping plate and the workpiece support meet can be. The resilient workpiece support can be applied by it to the shoe upper workpiece Compensate for the pressure exerted so that there are no pressure points. Here is the workpiece support the later outer side of the shoe upper workpiece facing. because its other side with the Reinforcement layer: to be provided. The yielding one Workpiece support and the clamping plate ensure that there is an intermediate shoe upper workpiece in the area of the raised surface of the workpiece support and the inner border of the Clamping plate arched upwards, this arching upwards due to the pressing together of the clamping plate and Workpiece support is supported. A highly arched area of the upper part of the shoe is thus formed to which the stiffening layer alone can be applied.
