Description

Verfahren zur Herstellung von nahtlosen Buchsen aus mit Kunstharz getränktem Gewebe Zusatz zum Zusatzpatent 8S4 447 Ins Patent 894447 ist ein Verfahren iur Herstellung von nahtlosen Buchsen aus mit Kunstharz getränktem Gewebe beschrieben, bei dem ein in an sich bekannter Weise vorgewickelter Rohrabschnitt unter Wärme durch einen sich erweiternden inneren Dorn gegen die ungeteilte Außenform gepreßt wird, in die ein die Lagerbuchse nach dem Pressen umschließender Metallmantel eingelegt ist.Process for the production of seamless bushings from synthetic resin Impregnated fabric Addition to additional patent 8S4 447 In patent 894447 is a method iur production of seamless bushings from fabric soaked with synthetic resin is described, in which a tube section pre-wound in a manner known per se under heat pressed against the undivided outer form by an expanding inner mandrel is inserted into which a metal jacket enclosing the bearing bush after pressing is.

Gemäß der Erfindung wird der in die äußere Preßform eingelegte Metallmantel wechselseitig eingeschnitten, so daß er eine in sieh geschlossene schlangenförmige Gestalt aufweist. Beim Verpressen wird der Metallmantel etwas gestreckt und sitzt dann beim Schrumpfen der Kunststoffbuchse nach dem Abkühlen fest auf der Buchse. According to the invention, the metal jacket placed in the outer mold cut alternately so that it has a closed, serpentine shape Has shape. When pressing, the metal jacket is stretched a little and sits then when shrinking the plastic bushing firmly on the bushing after cooling.
