Claim:
An axial bearing ( 11 ) for a banding roll ( 20 ) of a banding machine ( 10 ) with a shaft ( 62 ) which is rigidly attached to a machine frame ( 16 ) or chassis, and a rear cover plate ( 68 ) which is also rigidly attached, a hub ( 64 ) which is freely rotatable on the shaft ( 62 ) and a flange ( 74 ) which is arranged on a free face ( 96 ) of the shaft ( 62 ) with a front cover plate ( 18 ), wherein in the area of the flange ( 74 ) at least one bolt ( 84 ) protrudes radially from the shaft ( 62 ) and engages without protrusion in a guide slot ( 78 ) of a bayonet socket ( 76 ) which is detachably connected with the flange ( 74 ), wherein the guide slot ( 78 ) is open at its inner face and transforms rising into a curved apex ( 118 ), turns at a spacing a from the inner face ( 80 ) of the bayonet socket ( 76 ) and runs ending blind in the direction of the inner face ( 80 ) of the bayonet socket, a compression spring ( 88 ) is arranged clamped between a shaft holder ( 90 ) and the hub ( 64 ) on the shaft ( 62 ) and presses a roll core ( 70 ) with the banding roll ( 20 ) over the hub ( 64 ) in the axial direction onto the flange ( 74 ) and together with this forms a fast closure with the centred banding roll ( 20 ), where a spacing (a) corresponds to the spacing of the roll core ( 70 ) of the banding roll ( 20 ), inserted and not yet pressed on, from the rear cover plate ( 68 ).
