Description

In Spinnmaschinen-Streckwerken werden heute Oberwalzenbezüge und Spinnriemchen mit Ausnahme von Unterriemchen fast ausschließlich aus synthetischem Gummi verwendet, da man diese aus synthetischem Material in gleichbleibender Qualität und mit genauen Abmessungen herstellen kann. Obwohl die Entwicklung entsprechenden synthetischen Gummis sehr weit fortgeschritten ist, kommt es vor, daß in-,folge.-gewisser, meist klimatisch bedingter Umstände die Bezüge zum »Wickeln« neigen, d. h., es werden einzelne Fasern aus dem Faserverband herausgelöst, die sich auf dem Walzenbezug sammeln und im weiteren Verlauf einen Walzenwickel aus guten Fasern bilden. Auch bei einem.-Fadenbruch werden häufig die Fasern um den Walzenbezug herumgewickelt.Top roll covers and spinning aprons are used in spinning machine drafting systems today with the exception of lower aprons, almost exclusively made of synthetic rubber, because they are made of synthetic material in consistent quality and with accurate Can produce dimensions. Although the development of appropriate synthetic Gummis is very advanced, it happens that in-, consequential-certain, mostly Due to climatic conditions, the covers tend to "wrap", d. h., it will be individual fibers detached from the fiber structure, which are located on the roller cover collect and then form a roll of good fibers. Even in the event of a thread breakage, the fibers are often wrapped around the roller cover.

Bei einem anderen Verfahren wird die Oberfläche mit UV-Licht bestrahlt (Österreichische Patentschrift 196,286).- The 'Wiekelbildting @ one had so far' in - different ways bekgrälfif = So - the - rubber surface has been made rough, `e.g. by mixing in.; Suitable fillers (German patent 963,313). In another method, the surface is irradiated with UV light (Austrian patent specification 196,286).

Vielfach wird die Gummioberfläche mit Lack bestrichen, was aber zeitraubend und wegen der kurzen Lebensdauer des -Lackfilmes auch kostspielig ist =(Deutsclre :-@gtentsdhrift 17,752). Ein Nachbeliändeln der'-Oberfläche- -lverschiedenen gelösten Chemikalien hatte bislang nicht den gewünschten Erfolg: Es wurde nun gefunden, daß man das gefürchtete Wickeln auf Walzenbezügen und Riemchen äüs synthetischem Gummi bei Spinnmaschinen-Streckwerken vermeiden kann, wenn man auf die Oberfläche 2derartiger Walzen und Riemchen Tri-isocyanate aufbringt. Zu diesem Zweck löst man ein Tri-isocyanat z. B. in einem organischen Lösungsmittel und bestreicht dann die Oberfläche der Walzenbezüge oder der Riemchen mit dieser Lösung. 'Es ist- jedoch auch möglich, das Tri-isocyanat dampfförmig auf die Oberfläche der Walzenbezüge oder Riemchen aufzubringen. Besonders geeignet ist Tri-(isocyanato-phenyl)-thio-Phosphat. Beispiel Man fügt zu 30 Volumenteilen einer 20prozentigen Lösung vöii- --Tri-Cisocyanato-phenyl)-thio-Phosphat (Handelsname Desmodur RF) in Methyleuchlorid noch 70 Volumenteile . wasserfreies Chlorbenzol. Diese Lösung wird auf die Walzenbezüge aüfgepinselt. Nach dem Trocknen ist die Oberfläche derart verändert, daß die gefürchtete Wickelbildung nicht mehr auftritt. -The rubber surface is often coated with varnish, but this is time-consuming and because of the short lifespan of the lacquer film it is also expensive = (Deutsclre : - @ gtentsdhrift 17,752). A Nachbeliändeln the 'surface -l different solved Chemicals has not had the desired success so far: it has now been found that the dreaded winding on roller covers and straps made of synthetic rubber in spinning machine drafting systems can be avoided if you look at the surface 2 such Rolls and aprons tri-isocyanate applies. A tri-isocyanate is dissolved for this purpose z. B. in an organic solvent and then brushes the surface of the Roller covers or the aprons with this solution. 'However, it is also possible the tri-isocyanate in vapor form on the surface of the roll covers or aprons to raise. Tri- (isocyanato-phenyl) -thio-phosphate is particularly suitable. example One adds to 30 parts by volume of a 20 percent solution of vöii- - tri-cisocyanato-phenyl) -thio-phosphate (Trade name Desmodur RF) in methyl euchloride still 70 parts by volume. anhydrous Chlorobenzene. This solution is brushed onto the roll covers. After drying the surface is changed in such a way that the dreaded lap formation no longer occurs occurs. -
