Oie Herstellung von Zuschnitten, wie Schaftteilen, durch Hochfrequenz-Schweißen aus Leder bzw. lederähnlichen Flächenmaterialien ist nach wie vor mit Schwierigkeiten verbunden. Bekannt ist, zum Hochfrequenz-Schweißen dieser Materialien gewisse Schv/eißhilfsmittel zu verwenden. AIg solche wurden bisher Schweißfolien und Schweißklebfer auf der Basis von Polyvinylchlorid-Copolymeren eingesetzt. Die 30 hergestellten Schaftteile weisen «war einen guten Verbund auf, der allerdings im Griff als ausgesprochen hart zu bezeichnen ist, besitzen aber immer noch schwerwiegende anderweitige Nachteile. So lassen sich solche Schafttei3e nur zu Schuhteilen verarbeiten, die keine tragende Funktion besitzen. Bei Schuhteilen mit tragender Funktion, z, B, Riemchen an Sandalen, Senattabschlüssen am £ij>.schJLupf, verziehen sich die . mit diesen Schweißhilfsmitteln zu Schaftteilen verbundenen Schaftmaterialien t und die daraus hergestellten Schuhe verlieren ihre Paßform. Da in den auf diese Art hergestellten Schaftteilen keine Verstärkungsbändchen eingearbeitet werden können, die beim herkömmlich gefertigten Schuh unbedingt vorhanden sein müssen, besteht bei ihnen, insbesondere bei starker Beanspruchung, The production of blanks, such as shaft parts, by high-frequency welding from leather or leather-like sheet materials is still associated with difficulties. It is known to use certain welding aids for high-frequency welding of these materials. So far, welding foils and welding adhesives based on polyvinyl chloride copolymers have been used. The 30 shaft parts produced show a good bond, which, however, can be described as extremely hard in the grip, but still have other serious disadvantages. Such shaft parts can only be processed into shoe parts that have no load-bearing function. In the case of shoe parts with a load-bearing function, such as straps on sandals, flaps on the bottom, they warp. Upper materials t connected with these welding aids to form upper parts and the shoes made from them lose their fit. Since no reinforcement tapes can be incorporated into the upper parts produced in this way, which must be present in conventionally manufactured shoes, they have, especially under heavy use,

beständig die Gefahr des Einreißens am Schaftrand, wenn O.ber- und Futtermaterialien mit relativ geringer Einreißfestigkeit zur Schaftfertigung benutzt werden. Ein weiterer, besonders schwerwiegender Nachteil solcher Schaftteile ist/ daß sie naturgemäß nicht wasserdampfdurchlässig sind.constant risk of tearing at the edge of the shaft if above- and lining materials with relatively low tear resistance are used to manufacture shafts. Another, special The serious disadvantage of such shaft parts is / that they are naturally not permeable to water vapor.

Man hat auch schon versucht, zur Herstellung von Schaftteilen aus Leder bzw. lederähnlichen FlächenmaLerialien Polyvinylchlorid- oder Polyvinylidenchlorid-Gewebe als Schweißhilfsmittel zu verwenden. Das Hochfrequenz-Schweißen erfordert jedoch hierbei für diesen S£)ezifischen Arbeitsablauf unzumutbar längs Taktzeiten, während sich eine Erhöhung der Energiezuführung wegen der dann auftretenden Verbrennungen verbietet. Infolge der Sprödigkeit solcher Gewebe platzen überdies die Schweißnähte der Schaftteile schon nach wenigen Biegebeanspruchungen, was besonders bei niedrigen Außentemperaturen noch begünstigt v/ird-Attempts have also been made to produce upper parts made of leather or leather-like surface materials made of polyvinyl chloride or polyvinylidene chloride fabric as a welding aid to use. However, high-frequency welding requires unreasonably long cycle times for this specific workflow, while an increase in the energy supply is forbidden because of the burns that then occur. As a result of In addition, the brittleness of such tissue causes the weld seams of the shaft parts to burst after only a few bending loads, which is particularly important at low outside temperatures still favored v / ird-

Die vorliegende Erfindung betrifft ein noues Verfahren zur Herstellung von Zuschnitten für die Fertigung von Schuhen und Lederwaren und ist dadurch gekennzeichnet, daß man zwischen Ledar bzw. lederähnlichen Flächonmaterialien ein Gewebe anordnet, das mindestens zu 60 Gew.% aus Fäden oder Fasern besteht, die zwischen 80 und 13o°C schmelzbar sind, und dieses anschließend in üblicher Weise durch Hochfrequenz-Schweißen mit den Flächenmaterialien verbindet.The present invention relates to a new method of manufacture of cuttings for the production of shoes and leather goods and is characterized by the fact that between Ledar and leather-like flat materials arranges a fabric that at least 60% by weight consists of threads or fibers which can be melted between 80 and 130 ° C., and then this in the usual way Way by high frequency welding with the sheet materials.

Die werkstoffmäßige Beschaffenheit der Flächenmatexialien kann 'naturgemäß sehr verschiedenartig sein. Sie erstreckt sich von den verschiedensten Arten des Naturleders bis zu den bekannten portH sen oder nichtporösen lederähnlichen Kunststoffen. Als Beispiele seien angeführt: Ziegenleder r XYLEE, CORFAM, CLARINO (poröse, synthetische Schaftmaterialien der Firmen Glanzstoff AG, DuPont und Kurashiki Rayon), PVC-Folien, Krempelvliese aus Polyamid- und Cellulosefasern, die mit weichmacherbeständigem, vernetztem The material properties of the surface materials can naturally be very different. It extends from the most varied types of natural leather to the well-known porthous or non-porous leather-like plastics. Examples are: goat leather r XYLEE, CORFAM, CLARINO (porous, synthetic upper materials from Glanzstoff AG, DuPont and Kurashiki Rayon), PVC foils, carded nonwovens made of polyamide and cellulose fibers, which are cross-linked with plasticizer-resistant

doch sind in Abhängigkeit von der jeweiligen Werkstoffart natürlich Abweichungen möglicht however, depending on the type of material in question, deviations are of course possible t

Das er.findungsgemäß zwischen den Flächenmaterialien angeordnete Gewebe kann gänzlich aus Fäden oder Fasern bestehen, die einen Schmelzpunkt zwischen 8o und 13o°C aufweisen. Geeignet sind beispielsweise solche aus Polyätheramiden, wie die aus Bis-(3-aminopropyl)-ether und Adipinsäure, Propylen· bis-(3-aminopropyl)-äther und Adipinsäure, Butylen-bis-(3-aminopropyl)-äther und Adipinsäure hergestellten, aus Copolyamiden, wie die auc adipinsaurem Bi=-(3-aminopropyl)-äther und adipinsaurem Hexamethylendiamin, adipinsaurem Äthylen-bis-(3-aminopropyl)-äther und adipinsaurem Hexamethylendiamin, adipinsaurem Butylcn-bis- (3-airdnopropyl)-äther und adipinsaurem Hexamethylendiamin hergestiellen, aus Micchpolymerisaten von Nylon 6 und Nylon 66,- aus PVC/Polyvinylanetat-Copolymeren usw.The inventively arranged between the sheet materials Fabric can consist entirely of threads or fibers that have a melting point between 80 and 130 ° C. For example, are suitable those made from polyether amides, such as those made from bis (3-aminopropyl) ether and adipic acid, propylene bis (3-aminopropyl) ether and adipic acid, butylene bis (3-aminopropyl) ether and adipic acid made from copolyamides, such as the adipic acid Bi = - (3-aminopropyl) -ether and adipic acid hexamethylenediamine, adipic acid ethylene bis (3-aminopropyl) ether and adipic acid Hexamethylenediamine, adipic acid butylcn-bis- (3-airdnopropyl) -ether and hexamethylenediamine adipate Micchpolymerisaten of nylon 6 and nylon 66, - from PVC / polyvinylanetate copolymers etc.

Das Gewebe kann aber auch Fäden oder Fasern enthalten, die im angegebenen Schmelzbsreich noch nicht erweichen oder gar unschmelzbar sind, wie z. B. solche aus Polyestern, Polyamiden, Baumwolle usw. Ihr Anteil darf jedoch 4o Gew.% nicht überschreiten, da ansonsten gute Trennfestigkeitswerte der Zuschnitte nicht mehr gewährleistet sind.However, the fabric can also contain threads or fibers that are specified in Schmelzbsreich do not yet soften or are even infusible, such as. B. those made of polyesters, polyamides, cotton etc. Their proportion, however, must not exceed 40% by weight, otherwise good separation strength values of the blanks are no longer guaranteed.

Im Rahmen der Erfindung wird insbesondere angestrebt, daß das zwischen den Flächenmaterialien angeordnete Gewebe gleichzeitig die Funktion einer Verstärkungseinlage Übernimmt. Die mittels Hochfrequenz-Schweißen herbeigeführte Verbindung zweier Flächenmaterialien durch eine solche Verstärkungseinlage wird erfindungsgemäß einmal dadurch erreicht, daß man zwischen^lächenmaterialienIn the context of the invention, the aim is in particular that the fabric arranged between the sheet materials at the same time Takes over the function of a reinforcement insert. The connection of two flat materials brought about by high-frequency welding such a reinforcement insert is achieved according to the invention once that between ^ surface materials

ein Gewebe einer Dehnung von nicht mehr als 2o%, vorzugsweise von nicht mehr als lo% anordnet. Mit dieser Maßnahme wird das Verziehen bei Schuhtcilen mit tragender Funktion vermieden. Zur Erzielung hoher Bruch- und Weiterreißfestigkeiten der erfindungsc,emäß hergestellten Zuschnitte ist es außerdem besonders günstig, wenn man zwischen den Flächenmaterialien ein Gewebe einer Festigkeit von mindestens Io kp/cm anordnet. Die Festigkeit der hergestellten Zuschnitte läßt sich bei gleichzeitiger Vermeidung einer unvorteilhaft aussehenden größeren Dicke der Verstärkungseinlage überdies noch dadurch vorteilhaft beeinflussen, wenn man zwischen den Flächenmaterialien ein Gewebe eines Quadratraetergewichtes von 15o bis 25c g anordnet.a fabric with an elongation of no more than 20%, preferably of not more than lo%. With this measure will the distortion of shoe pieces with a load-bearing function avoided. To achieve high breaking and tear strengths of the According to the invention, it is also special favorable if a fabric with a strength of at least Io kp / cm is arranged between the sheet materials. The strength of the blanks produced can be reduced while avoiding an unfavorable-looking larger The thickness of the reinforcement insert can also be advantageously influenced if a fabric is placed between the sheet materials a square meter weight of 15o to 25c g.

Als Verstärkungseinlagen können anhand der angegebenen Maßnahmen naturgemäß Gewebe von recht unterschiedlichem Aufbau verwendet werden. Eine geeignete Auswahl aus den gegebenen Möglichkeiten wird jeweils in erster Linie vom beabsichtigten Einsatzgebiet der Zuschnitte abhängen und kann durch einfache Probierctrbcit leicht getroffen werden. Zu beachten ist außer den angegebenen Randbedingungen nur, daß das Gewebe bzw. die es aufbauenden Fäden oder Fasern von der Herstellung her keine Avivagemittcl mehr enthalten, da diese die Trennfestigkeitswerte der hochfrequenzverschweißten Zuschnitte herabsetzen.With the aid of the measures specified, fabrics of very different structures can naturally be used as reinforcement inserts will. A suitable selection from the options available depends primarily on the intended area of application depend on the blanks and can be done by simply trying it out be easily hit. In addition to the specified boundary conditions, the only thing to note is that the tissue or the structures that build it up Threads or fibers from the manufacturing process no longer contain any finishing agents, since these reduce the separation strength values of the Reduce high frequency welded blanks.

Die mit dem erfindungsgemäßen Verfahren in einfacher Weise hergestellten Zuschnitte, unter denen man bekanntlich die mit einem Messer oder Stanzmesser zuzuschneidenden Teile für Lederwaren, insbesondere Schuhschäfte, versteht,können unmittelbar zur Herstellung von Herron-, Damen- und Kindersandalen, von Slingpumps, von Schuhteilen mit tragender Funktion, aber auch von Gürteln, Trageschlaufen für Taschen, Leibriemen usw. verwendet werden, ohne daß diese die oben angegebenen Nachteile aufweisen. Bei Verwendung von wasserdampfdurchlässigen Flächenmaterialien wird mit ihra auch die Wasserdampfdurchlässigkeit der hergestellten Zuschnitte gewährleistet.Those produced in a simple manner using the process according to the invention Blanks, which are known to include the parts for leather goods to be cut with a knife or punching knife, especially shoe uppers, understand, can be used directly for production from Herron, women's and children's sandals, from sling pumps, from shoe parts with a load-bearing function, but also from belts, Carrying loops for bags, waist straps, etc. can be used without these having the disadvantages indicated above. at The use of water-vapor-permeable sheet materials also increases the water-vapor permeability of the manufactured Cuts guaranteed.

Die Bruchdehnung liegt also bei Schweißteilen ohna Gewebeverstärkung beträchtlich höher und die Bruchfestigkeit und Einreißfestigkeit niedriger äl3 bei Schaftteilen mit einer Gewebeverstärkung. Das hat zur Folge, daß Zuschnitts ohne Gewebeverstärkung eine ungenügende Formbeständigkeit aufweisen, überdies vzird die Wasserdampfdurchlässigkeit durch den Kleberauftrag i^ Gegensatz zu den Beispielen 1 bis 3 aufgehoben.The elongation at break is therefore in welded parts without fabric reinforcement considerably higher and the breaking strength and tear resistance lower äl3 for shaft parts with a fabric reinforcement. That has the consequence that cutting without fabric reinforcement is insufficient Have dimensional stability, moreover the water vapor permeability due to the application of glue i ^ contrast to the examples 1 to 3 canceled.
