Abstract
A device for oil-impermeably sealing a stationary hood (6) off from a rotating, tumbling barrel, containing at least one stationary packing cord (7) which is forced against a race (8) by a pre-stressed and compressed gasket (9). The race is part of the barrel and rotates along with it. A cap (10) is connected to the hood (6) and demarcates in conjunction with part of the hood's end wall a region of expansion for the packing cord (7) and the gasket (9).
