Description
Verfahren zur Herstellung von spezifisch leichten Gummisohlen bei gleichzeitiger Anvulkanisation an den Schuhschaft Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von spezifisch leichten Gummisohlen bei gleichzeitiger Anvulkanisation an den Schuhschaft, ins besondere unter Verwendung einer Gummimischung. Process for the production of specifically light rubber soles simultaneous vulcanization to the shoe upper The invention relates to a process for the production of specifically light rubber soles at the same time Vulcanization to the upper part of the shoe, in particular using a rubber compound.
Es sind Vulkanisationspressen bekannt, bei denen der mit dem Schaft überzogene Leisten unter Druck in den Formrahmen eingeführt wird, wobei letzterer für sich besonders anhebbar ist und wobei der Leisten aufheizbar ist. Vulcanization presses are known in which the one with the shaft coated strips is introduced under pressure into the mold frame, the latter is particularly liftable for itself and wherein the bar can be heated.
Beim Herstellen von Teilen aus Blähmittel enthaltendem Kautschuk ist es bekannt, zunächst in einer Form eine Teilvulkanisation durchzuführen, dann den Formling vom Druck zu entlasten und anschließend in einer Form die Ausvulkanisation vorzunehmen. When making parts from rubber containing blowing agents it is known to carry out a partial vulcanization first in a mold, then to relieve the molding from the pressure and then vulcanize it in a mold to undertake.
Ferner ist bekannt, hierbei den Formling vom Druck zu entlasten und anschließend den Formling wieder teilweise zusammenzudrücken und ihn so auszuvulkanisieren. It is also known to relieve the molding from the pressure and then partially compress the molding again and vulcanize it out.
Demgegenüber besteht die Erfindung darin, daß in Abhängigkeit von der verwendeten Gummimischung zunächst für eine bestimmte Zeit in der Preßform eine Teilvulkanisation unter Druck vorgenommen wird und hierauf sodann unter Beibehaltung der äußeren Sohlenform eine weitgehende Druckentlastung der im Vulkanisationsvorgang befindlichen Gummimasse zur Porenbildung und die endgültige Ausvulkanisation erfolgt. In contrast, the invention consists in that depending on the rubber mixture used initially for a certain time in the mold Partial vulcanization is carried out under pressure and then while maintaining it the outer sole shape largely relieves pressure during the vulcanization process located rubber compound for pore formation and the final vulcanization takes place.
Ferner ist es zweckmäßig, daß im Anschluß an die Druckentlastung ein erneutes Pressen der Gummimischung auf annähernd gewünschte Sohlenstärke mit endgültiger Ausheizung erfolgt. It is also useful that after the pressure relief a renewed pressing of the rubber mixture to approximately the desired thickness of the sole final heating takes place.
Vorteilhaft ist es weiter, daß für die Herstellung der Sohle aufschäumbare Stoffe, insbesondere auf Polyurethanbasis, Verwendung finden. It is also advantageous that foamable for the production of the sole Substances, especially those based on polyurethane, are used.
Die Erfindung ermöglicht erstmalig die Herstellung von Schuhwerk mit einer anvulkanisierten Porengummisohle in einem Arbeitsgang. Bisher war es nur möglich gewesen, an Schuhwerk Gummisohlen ohne Porenbildung anzuvulkanisieren oder aber Porengummi in Form von Platten herzustellen, diese zu Sohlen auszuschneiden und an den Schuh anzukleben. The invention enables the manufacture of footwear for the first time with a vulcanized pore rubber sole in one operation. So far it was just it has been possible to vulcanize rubber soles on footwear without pore formation or but to produce pore rubber in the form of plates and cut them out to make soles and to stick to the shoe.
Das Verfahren bedeutet also eine wesentliche Beschleunigung und Verbilligung der Herstellung von Schuhen mit anvulkanisierter Porengummisohle.The process means a significant acceleration and cheaper the manufacture of shoes with vulcanized pore rubber soles.
Die Erfindung bezieht sich nicht nur auf die Herstellung von Schuhwerk mit anvulkanisierter Gummisohle, sondern ebenso auf ein Schuhwerk mit Sohlen aus aufschäumbaren Stoffen, insbesondere auf Polyurethanbasis. Es hat sich gezeigt, daß es möglich ist; Sohlen - und zwar sowohl Lauf- als auch Zwischensowie gegebenenfalls Brandsohlen - mit Vorteil aus Schaurm1sunststoffen auf Polyurethanbasis herzustellen, wobei es günstig ist, die Schaumkunststoffsohlen gleichzeitig bei der Herstellung und Formung fest mit dem Schuhschaft zu verbinden. Hierfür kann gegebenenfalls eine zusätzliche Zwischenlage beispielsweise in Form eines Rahmens zwischen Schuhschaft und Sohle zwischengeschaltet werden zwecks Erzielung einer besonders guten Haftung sowie gegebenenfalls zur Wärmeisolierung des Schuhschaftes beim Ausschäumen. Neben der Verarbeitung von Kunststoffen auf Polyurethanbasis, wie z. B. auf Polyure¢hankombinationen, können mit Vorteil auch Schuhe mit Sohlen aus anderen Schaumstoffen, wie z. B. auf der Basis von Polystyrol, Acetylcellulose od. dgl., hergestellt werden. The invention not only relates to the manufacture of footwear with vulcanized rubber sole, but also on footwear with soles foamable substances, in particular based on polyurethane. It has shown, that it is possible; Soles - both running and intermediate as well as possibly Insoles - with advantage Manufacture foam plastics based on polyurethane, whereby it is favorable to have the foam plastic soles at the same time during the production and molding firmly to connect to the shoe upper. For this purpose, a additional intermediate layer, for example in the form of a frame between the shoe upper and sole are interposed in order to achieve particularly good adhesion and, if necessary, for thermal insulation of the shoe upper when foaming. Next to the processing of plastics based on polyurethane, such as. B. on polyurethane combinations, Shoes with soles made of other foams, such as B. on the basis of polystyrene, acetyl cellulose or the like., Are produced.
Die Druckentlastung der im Vulkanisntionsvorgang befindlichen Gummimass e zur Porenbildung wird unter Beibehaltung der seitlichen äußeren Sohlenform vorgenommen, und zwar durch Senken des Preßstempels. Sobald sich genügend Poren gebildet haben, erfolgt ein erneutes Pressen der Gummimasse auf annähernd gewünschte Sohlenstärke mit anschließender Ausheizung und Anvulkanisation. The pressure relief of the rubber compound in the vulcanization process e for pore formation is carried out while maintaining the lateral outer sole shape, namely by lowering the ram. As soon as enough pores have formed, the rubber compound is pressed again to approximately the desired thickness of the sole with subsequent heating and vulcanization.
