Abstract

A drive shaft is surrounded by a winding drum, which consists of a plurality of axially aligned drum rings. A plurality of pressure plungers are radially slidably mounted in said shaft and radially aligned with all said drum rings and spaced apart in the peripheral and axial directions of said shaft and arranged in groups disposed in respective sectors of said shaft. Pressure-applying means for applying fluid pressure to said pressure plungers so as to force them radially outwardly against said drum rings to hold the latter clear of said shaft comprise a plurality of pressure fluid conduits for applying fluid pressure to respective groups of said pressure plungers.
