3c of the bottom 3d the sealing ring 18 is situated at an outer diametral zone of the base 3c it is feasible to position the sealing ring 18 on the edge face 3a that is at an outer diametral zone of the licker in 3 the seal assembly 16 is formed of a sealing ring 18 made for example of felt and a spring ring 19 made for example of foam plastic the inner radial surface 18b of the sealing ring 18 and the outer radial surface 19a of the spring ring 19 are firmly bonded for example glued to one another the outer radial surface 18a of the sealing ring 18 is in a sliding contact with the inner surface 17a of the side wall 17 whereas the outer radial surface 19b of the spring ring 19 is stationarily affixed to the outer radial surface 3c of the base 3d it is also feasible in the alternative to attach the spring 19 to the wall 17 in which case the surface 18a of the sealing ring 18 contacts the surface 3c of the radial base 3d the embodiment illustrated in fig3 includes a cross sectionally u shaped annular housing 20 receiving the two part seal assembly 16 the sealing ring 18 and the spring ring 19 are supported together in the unilaterally open annular housing 20 by a glue connection between the outer radial surface 19b of the spring 19 and the inner bottom face 20a of the housing 20 the outer radial face 20b of the housing 20 is secured to a radial end face of the roll such as the outer face 3c of the bottom 3d shown in fig2.
