Für maschenbildende Maschinen bestimmter Satz von Nadeln od. dgl.
EMI1.1
<Desc/Clms Page number 2>
Bei den beschriebenen Herstellungsverfahren werden die Nadeln od. dgl. in genauer Lage zueinander durch die sägezahnartigen Teile der Form gehalten, während das Bakelit die Nadelenden umschliesst, so dass nach Beendigung des Formens die Nadeln od. dgl. sehr fest an ihrem Platz gehalten werden und regelmässig und gleichförmig aus dem Bakelitträger hervorstehen.
Jeder Träger kann mit zwei Bohrungen versehen sein, die es gestatten, den Träger durch Schrauben od. dgl. an der Tragbare usw. abnehmbar zu befestigen.
Der Ausdruck Kunstmasse"umfasst vor allem Kunstharze, im besonderen solche, die thermoplastisch sind, z. B. die als"Bakelite"bekannten Phenolharze. Die Verwendung ist jedoch nicht hierauf beschränkt, da auch andere bekannte organische Stoffe oder Verbindungen, die thermoplastisch sind und ein geringeres spezifisches Gewicht als die vorerwähnten Metallverbindungen haben und welche beim Formen unter Einwirkung von Wärme und Druck fest und hart werden und ihre Festigkeit und Härte unter normalen Arbeitsbedingungen bewahren, verwendet werden können. Solche thermoplastische Stoffe enthalten beispielsweise organische Cellulosederivate, wie Celluloseester und Celluloseazetat, weiters Vinylester, organische Derivate von Gummi, wie Ebonit und Vulkanit.
Je nach der geforderten Festigkeit und Leichtigkeit werden geeignete leichte Füllstoffe für die Formmasse gewählt, so beispielsweise Holzmehl.
Zum Halten der Nadeln in der gewünschten Lage während des Bildens des Trägers können an Stelle der Zahnungen, welche mit den Teilen der Form aus einem Stück bestehen, auch kleine Träger dienen, in welche die Schäfte der Nadeln eingelegt oder eingesetzt werden und die in die Form eingebracht und mit den Nadeln in das Bakelit eingebettet werden. Auch kann der Bakelitträger durch Einlagen verstärkt werden. Diese Verstärkungen können z. B. aus einem Gewebestreifen oder einem dünnen Stab aus Metall oder anderm Material bestehen, der gezahnt um die Schäfte herumgeht und mit ihnen in Berührung steht.
Die erfindungsgemässen Nadel-od. dgl. Sätze können solche Nadeln od. dgl. haben, die üblicher- weise in Wirk-und Raschelmaschinen u. dgl. verwendet werden. Die Schäfte der Nadeln od. dgl. können jedoch auch aufgerichtete Endvorsprünge haben, was dazu beiträgt, die Schäfte in der plastischen Masse noch mehr zu verankern.

EMI1.1
<Desc / Clms Page number 2>
In the manufacturing process described, the needles or the like are held in a precise position relative to one another by the sawtooth-like parts of the mold, while the bakelite encloses the needle ends, so that the needles or the like are held very firmly in place after the molding has been completed protrude evenly and evenly from the Bakelite support.
Each carrier can be provided with two bores, which allow the carrier to be detachably attached to the portable etc. by screws or the like.
The term synthetic material "includes above all synthetic resins, in particular those that are thermoplastic, for example the phenolic resins known as" Bakelite ". However, the use is not limited to this, since other known organic substances or compounds that are thermoplastic and have a lower specific weight than the aforementioned metal compounds and which become solid and hard when molded under the action of heat and pressure and retain their strength and hardness under normal working conditions. Such thermoplastic materials contain, for example, organic cellulose derivatives such as cellulose esters and cellulose acetate, furthermore vinyl esters, organic derivatives of rubber such as ebonite and vulcanite.
Depending on the required strength and lightness, suitable lightweight fillers are selected for the molding compound, for example wood flour.
To hold the needles in the desired position during the formation of the carrier, instead of the serrations, which consist of one piece with the parts of the mold, small carriers can also be used, in which the shafts of the needles are inserted or inserted and which are in the mold and embedded with the needles in the Bakelite. The Bakelite support can also be reinforced with inserts. These reinforcements can e.g. B. consist of a fabric strip or a thin rod of metal or other material that goes around the shafts with teeth and is in contact with them.
The inventive needle od. Similar sets can have such needles or the like, which are usually used in knitting and Raschel machines and the like. Like. Be used. The shafts of the needles or the like can, however, also have upright end projections, which helps to anchor the shafts even more in the plastic mass.
