摘要： The present invention relates to an end packing (20, 40, 60, 70, 80) for a deflection compensated roll. The roll including a stationary shaft (1) and a roll shell (2), bearing-mounted rotatably therearound and having each end thereof provided with a shaft-enclosing annular end cap (3). The end cap (3) has its surface internal in the axial direction of the roll or its surface external in the axial direction formed with a sealing surface (10, 50, 61, 71, 81). The end packing elements (20, 40, 60, 70, 80) are provided with an annular packing member (12; 42; 62; 72; 82) extending around the shaft (2) and including a front face, which is directed towards said sealing surface (10, 50, 61, 71, 81) and which is in contact with the sealing surface (10, 50) or separated from the sealing surface (61, 71, 81) by a gap constituting an axially directed narrow slot. The packing member (12; 42; 62; 72; 82) is provided with elements connected to a supply of compressed air for delivering compressed air into a cavity (14, 44, 69, 92, 105) between the packing member and the sealing surface, whereby the compressed air striving to flow between the packing member's front face and the sealing surface into and out of the roll functions as a seal.
