Abstract

Wire is lamellar in shape. Pref. the front zone is after-hardened, or a hard material is applied. Both front surfaces may be hardened. Hardening or application may be performed on the running strip before processing, or to the cut wire or finished reed.

Description

Rietstab mit örtlich begrenzter Härtungs-Zone Bekanntlich werden für die Herstellung von Webrieten (Webblättern) lamellenförmige Rietstäbe aus hochwertigen Stahlsorten verwendet. Rietstab with a localized hardening zone are known for the production of reeds (reeds) lamellar reed rods made of high quality Steel grades used.

Ferner werden diese Rietstäbe beim Einsatz des Webrietes im Webstuhl durch die scheuernde Wirkung der Kettfäden bei der Fachbildung-und beim Anschlag des Schußfadens an den Warenrand und besonders auch durch den beim Eirfrag des Schußfadens am Webriet vorbeigleitenden Schützen sehr stark beanspricht Durch diese Beanspruchung werden die Rietstäbe "scharf", so daß die Kettfäden beschädigt werden und der Webvorgang behindert wird. Hierdurch ist neben anderen Ursachen der Letensdauer von Webrieten eine verhältnismäßig enge Grenze gesetzt0 Erfindungsgemäß wird eine wesentliche Verlängerung der Lebensdauer dieser Webriete erreicht, wenn man die äußeren Flächen des Rietstabes entweder örtlich härtet oder bei Verwendung billigeren Materials mit einer dünnen Schicht besonders harten Materials versieht. Die beigefügten Abbildungen zeigen einige Ausführungsbeispiele derartiger örtlicher Härtungs-Zonen.Furthermore, these reed sticks are used when the weaving reed is used in the loom due to the abrasive effect of the warp threads during shedding and when being tacked on of the weft thread to the edge of the goods and especially also through the weft thread when Eirfrag shooters sliding past the Webriet very heavily due to this stress the reed bars become "sharp", so that the warp threads are damaged and the weaving process is hindered. This, among other causes, is the longevity of weaving rivets a relatively narrow limit is set0 According to the invention, an essential one Extension of the service life of this weaving machine can be achieved by removing the outer surfaces of the reed bar either hardens locally or if cheaper material is used with a thin layer of particularly hard material. The attached images show some embodiments of such local hardening zones.

Ein besonderer Vorteil dieses Verfahrens ist auch darin zu sehen, daß man bei der Verwendung nachträglich aufgetragener härterer Schichten, wie es z.B. mittels des Elektronenstrahl-Schweißens und -Härtens möglich ist, die Form der aufgetragenen Schicht beliebig wählen kann; Schweiß man z.B. einen runden oder halbrunden Stab oder Draht auf, so erhält der Rietstab eine für das Weben sehr günstige Form des Frontprofils. Mit anderen Mitteln ist eine solche Wirkung nur schwer zu erzielen.A particular advantage of this process can be seen in the fact that that when using subsequently applied harder layers like it e.g. by means of electron beam welding and hardening is possible, the shape the applied layer can be chosen arbitrarily; For example, you weld a round or On a semicircular rod or wire, the reed rod is given a very favorable one for weaving Shape of the front profile. Such an effect is difficult to achieve by other means achieve.
