ABSTRACT:
A sealing arrangement is provided between the shaft of a mixing tool and the wall of a housing of a mixing and kneading machine, the sealing arrangement having a housing liner and a gland member which can be axially displaced against a support ring arranged between the shaft and the housing liner. The liner is formed by an outer sleeve sealingly placed in the wall of the housing and an inner sleeve resiliently abutted against the outer sleeve to define an annular space therebetween which is sealed by elastic seals which are pressurized by a pressure medium. A sealing arrangement of juxtaposed elastic gaskets is arranged in an annular space between the inner sleeve and the shaft and the gaskets are axially compressed between the gland member and an inward projection at the end of the inner sleeve.
