Abstract
Method of operating machines with rotating units and machine with a rotating unit, in particular a packaging machine with a (folding) turret. Rotating units, in particular folding turrets (10) of packaging machines, must be supplied with oil as a lubricant. At the same time, areas supplied with oil must be sealed with respect to those areas into which oil must not penetrate. In the case of a folding turret (10), a supporting part (11) is confined with respect to a rotating part (12) by means of a rotating supporting rim (46) and a supporting ring (48) surrounding the latter. The supporting rim (46), as a rotating element, is provided with grooves (52, 53, 54) which prevent passage of oil in the area of a sealing gap (51) formed between the supporting rim (46) and the supporting ring (48).
