An axial bearing, for a spooling roller on a spooling machine, with a shaft fixed to a machine frame, or to a machine chassis, a fixed rear cover disc, a hub freely rotating about the shaft and a flange, arranged on the free front face of the shaft with a front cover disc. At least one stud chamfers in the radial direction, away from the shaft in the region of the flange, engaging in but without projecting beyond a guide slot of a bayonet sleeve, detachably connected to the flange. The open guide slot, on the front face, rises up to an arched peak, turns away from the front face of the bayonet sleeve at a separation and runs toward the front face with a blind terminus. A pressure spring, tensioned on the shaft, is arranged between a shaft mounting and the hub, which presses the roller core with the spooling roller, over the hub, in the axial direction on the flange and forms therewith a rapid closure with the centered spooling roller. The separation (a) corresponds to the separating of the roller core, or the mounted but not yet pressurized spooling roller, from the rear cover disc.

The invention claimed is: 1. 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
The invention claimed is: 1. 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). 2. The axial bearing (11) according to claim 1, wherein two diagonally opposing bolts (84) protrude from the shaft (62) into the guide slots (78). 3. The axial bearing (11) according to claim 2, wherein the guide slots (78) for the bolts (84) run with preferably linear or degressive gradient, transform into a circular arc with each of the curved apex (118) and fall preferably linearly. 4. The axial bearing (11) according to claim 1, wherein the gradient of the guide slot (78) has an angle α of 30 to 60°. 5. The axial bearing (11) according to claim 1, wherein the guide slot (78) after the apex has an end position with a spacing of (0.3 to 0.7) from the inner face (80) of the bayonet socket (76). 6. The axial bearing (11) according to claim 5, wherein the guide slots have a catch after reaching the end position. 7. The axial bearing (11) according to claim 1, wherein a spacing (t) of a face (124) of the bayonet socket (76) from a free face (122) of the flange (74) is adjustable according to the width (b) of the banding roll (22). 8. The axial bearing (11) according to claim 7, wherein arranged in an axial bore (120) starting from the free face (96) of the shaft (62) is arranged a compression spring (100) and a longitudinally displaceable pressure pad (98), where the position of the pressure pad (98) and the associated bayonet socket (76) is adjustable with a bolt (102). 9. The axial bearing (11) according to claim 1, wherein the roll core (70) lies with play on the hub (64) and is centered with spring clamps (94). 10. The axial bearing (11) according to claim 1, wherein the flange (74) in the area of the inserted roll core (70) has a ring stop (92) which has an inner glide face. 11. The axial bearing (11) according to claim 1, wherein outside the roll core (70) and extending in the radial direction is arranged a brass brush (114) as an earth contact, the surface of which can be recessed via a spacer (116).
