Abstract

Die Erfindung betrifft ein Streckwerk zum Verziehen eines Vorgarns mit durch Eingangs-, Mittel- und Ausgangswalzenpaare gebildeten Verzugsfeldern sowie einer angeschlossenen Verdichtungszone, wobei an die Ausgangsoberwalzen über ein Käfigelement Lieferoberwalzen angeschlossen sind und das Käfigelement durch eine Belastungsfeder, die als Blattfeder ausgebildet ist, in Richtung auf Lieferunterwalzen hin beaufschlagt wird.The invention relates to a drafting system for warping a roving formed by input, middle and output roller pairs drafting zones and a connected compression zone, being connected to the output top rollers via a cage delivery top rollers and the cage element by a loading spring, which is designed as a leaf spring, in the direction is applied to Lieferunterwalzen out.

Erfindungsgemäß ist vorgesehen, dass das Käfigelement (25) eine erste Führungs- und Aufnahmeeinrichtung (29) aufweist, deren lichter Durchmesser geringfügig über dem Durchmesser einer Achse (13) des Ausgangsoberwalzenpaares (4o) liegt, an der das Käfigelement (25) gelagert ist und dass die Belastungsfeder (15) mit einem Ende stationär an den Pendelträger (5) angeschlossen und im Bereich ihres gegenüberliegenden, freien Endes (14) über ein Zwischenglied (16, 17, 18) beweglich mit dem die Lieferoberwalzen (11o) aufnehmenden Käfigelement (25) verbunden ist.

Figure imgaf001
According to the invention, the cage element (25) has a first guiding and receiving device (29) whose clear diameter is slightly above the diameter of an axis (13) of the top roller pair (4o) on which the cage element (25) is mounted and in that the loading spring (15) is connected at one end to the pendulum support (5) in a stationary manner and in the region of its opposite, free end (14) via an intermediate member (16, 17, 18) movable with the cage element (25) receiving the delivery top rollers (11o) ) connected is.
