Description
Verfahren zur Herstellung von Schuhwerk Es ist bekannt, daß sich die durch große Festigkeit, Elastizität und chemische Widerstandsfähigkeit ausgezeichneten S,uperpolyamide zur Herstellung von Kunstleder eignen.Process for the manufacture of footwear It is known that the distinguished by great strength, elasticity and chemical resistance S, superpolyamides are suitable for the production of artificial leather.
Es ist ferner ein Verfahren zur Herstellung von Schuhen aus Faserbrei bekannt, bei dem man den Faserbrei durch ein Rohr in eine Form für den Schuh drückt. In der Form wird der Faserfrei entwässert, setzt sich und nimmt Schuhgestalt an. Faserbrei ist nun aber ein wenig geeigneter Stoff für die Herstellung von Schuhwerk, und die vor Jahrzehnten vorgeschlagene pdmitive Arbeitsweise blieb deshalb für die Schuhherstellung unbeachbet. It is also a method of making shoes from pulp known, in which the pulp is pressed through a pipe into a shape for the shoe. The fiber-free is drained in the mold, sits down and takes on the shape of a shoe. But pulp is now a less suitable material for the production of footwear, and the pdmitive working method proposed decades ago therefore remained for the Shoe manufacture irrespective of.
Es wurde nun gefunden, daß man in außerordentlich einfacher Weise Schuhwerk oder größere zusammenhängende Teile davon, insbesondere solche, die bisher ebenso wie die Schuhe selbst aus Leder angefertigt wurden, herstellen kann, wenn man sie aus Superpolyamiden oder Sup,erpolyurethanen durch Spritzguß erzeugt. It has now been found that in an extremely simple manner Footwear or larger coherent parts thereof, especially those previously just as the shoes themselves were made of leather, can make, though they are produced from super polyamides or super polyurethanes by injection molding.
Auf diese Weise können alle bei der bisherigen Herstellungsweise von Schuhwerk gebräuchlichen Arbeitsgänge, wie Zurechtschneiden des Leders, Stanzen, Pressen, Verkleben, Vernähen und Nageln, fortfallen oder zum mindesten außerordentlich stark eingeschränkt werden. Man kann aus Superpolyamiden oder Superpolyurethanen flach dem Spritzgußverfahren beispielsweise Sandalen, Sandaletten, Pumps, Opanken. S)ortschuhe, Bade- oder Strandschuhe und ähnliche in einem einzigen Arbeitsgang herstellen. Es lassen sich dabei Halterungen, wie Ränder, Oesen, Lappen, Schnallen u. dgl., ferner Schutzteile gegen Abnutzung und Gleiten, wie Nägel, Stollen u. dgl., und auch Ausfütterungen mit an- hzw. einspritzen. In this way, everyone can use the previous production method Common operations of footwear, such as cutting the leather to size, punching, Pressing, gluing, sewing and nailing, omitted or at least extraordinary be severely restricted. You can make from super polyamides or super-polyurethanes flat the injection molding process, for example sandals, sandals, pumps, opanks. Local shoes, bathing or beach shoes and the like in a single operation produce. It can be brackets, such as edges, eyelets, lobes, buckles and the like, also protective parts against wear and sliding, such as nails, studs and the like, and also linings with anhzw. inject.
Man kann auch Sohlen und Absätze einzeln oder zusammenhängend durch Spritzguß aus Superpolyamiden oder Superpolyure thanen herstellen und dann mit ihnen gleichfalls aus Superpolyamiden hergestellte Schuhoberteile verbinden, beispielsweise durch Vernähen, Verkleben oder Verschweißen. You can also use soles and heels individually or together Manufacture injection molding of super polyamides or super polyure thanen and then with them also connect shoe uppers made of superpolyamides, for example by sewing, gluing or welding.
I)urch Anwendung von Spri.tzgußmaschinen mit mehreren Zylindern, in denen jeweils Superpolyamide oder Superpolyuretaae verschiedener Härte, z. B. verschiedenen Füllstoffgehalts, enthalten sind, kann man auch in einem Arbeitsgang Schuhteile verschiede ncr Härte, z.B. einen Absatz mit einer llarteil, besonders abriebfesten Lauffläche und einem weicheren, elastischen und federnden Oberteil, herstellen und so nahtlose tOrgänge zwischen den härteren und den weicheren Schichten durch Verschweißung und Verschmelzung des Spritzgußmaterials erzeugen. I) by using injection molding machines with several cylinders, in each of which Superpolyamides or Superpolyuretaae of different hardness, z. B. different filler content, can also be used in one operation Shoe parts of different hardness, e.g. a heel with a flat part, especially abrasion-resistant tread and a softer, elastic and springy upper part, create seamless gateways between the harder and the softer layers by welding and fusing the injection molding material.
Ebenso kann man durch Verwendung verschiedenfarbigen Materials L'bergänge und Abstufungen. in den Farben erzeugen.Likewise, by using different colored materials, you can create transitions and gradations. generate in the colors.
