Abstract

Eine Federwelle mit einer Gewebewelle (1) weist eine Feder (6) auf, die zwischen einer Federführungsstange (12) und einem Federführungsteil (15) vorgesehen ist. An der Federführungsstange (12) sind zwei Vorsprünge mit Schrägflächen (26) und am Federführungsteil (15) sind zwei Ausschnitte mit Schrägflachen (25) vorgesehen. Bei ausgebauter Federwelle greifen die Vorsprünge mit den Schrägflächen (26) unter der Wirkung des achsialen Zuges der Feder (6) in die Ausschnitte mit den Schrägflächen (25) ein und verhindern ein Verdrehen der Federführungsstange (12) und des mit ihr verbundenen Spannteils (8) und damit ein Entspannen der Feder (6).

Figure 00000001
A spring shaft with a fabric shaft (1) has a spring (6) which is provided between a spring guide rod (12) and a spring guide part (15). Two projections with inclined surfaces (26) are provided on the spring guide rod (12) and two cutouts with inclined surfaces (25) are provided on the spring guide part (15). When the spring shaft is removed, the projections with the inclined surfaces (26) engage in the cutouts with the inclined surfaces (25) under the action of the axial tension of the spring (6) and prevent the spring guide rod (12) and the tensioning part (8 ) and thus a relaxation of the spring (6).
