The rotation body includes a first basic side and a second basic side different from the first basic side and a bearing. The bolt is arranged on the bearing via the first basic side such that the rotation body can be rotated about the bolt in the circumferential direction of the second basic side when the container is sealed. The seaming roll further includes an exchangeable seaming profile for seaming a container lid with a body of the container and a fastening mechanism. The exchangeable seaming profile is detachably connected to the rotation body via the fastening mechanism. ## Claims ### Claim 1 A seaming roll for sealing a container comprising: a rotation body rotatable on a bolt configured to seal the container, the rotation body comprising a first basic side and a second basic side different from the first basic side and a bearing, the bearing arranged on the bolt via the first basic side such that the rotation body is capable of being rotated about the bolt in a circumferential direction of the second basic side when the container is sealed; an exchangeable seaming profile configured to seam a container lid with a body of the container; and a fastener, the exchangeable seaming profile detachably connected to the rotation body via the fastener, the rotation body comprising a cover configured to seal the bearing and the seaming profile being capable of being placed over the cover onto the rotation body. ### Claim 2 (depends on 1) The seaming roll according to claim 1, wherein the fastener comprises a pin on the rotation body and a notch on the seaming profile, and the seaming profile with the notch is capable of being connected to the pin on the rotation body in a torque-proof and force-locking manner. ### Claim 3 (depends on 1) The seaming roll according to claim 1, wherein and the cover is detachably arranged on the second basic side of the rotation body. ### Claim 4 (depends on 2) The seaming roll according to claim 2, wherein the cover is detachably arranged on the second basic side of the rotation body, the cover comprises the pin and the cover is rotatably arranged on the second basic side of the rotation body such that the seaming profile is capable of being placed with the notch over the cover onto the rotation body in a first cover position and, after rotation of the cover from the first cover position to a second cover position, is connected to the rotation body in a torque-proof and force-locking manner. ### Claim 5 (depends on 4) The seaming roll according to claim 4, wherein the cover is a polygon, and one corner of the polygon is the pin of the fastener. ### Claim 6 (depends on 3) The seaming roll according to claim 3, wherein the fastener comprises a thread arranged on the rotation body and a counter thread is arranged on the cover, the seaming profile fastened to the rotation body over the cover. ### Claim 7 (depends on 3) The seaming roll according to claim 3, further comprising a safety mechanism arranged between the rotation body and the cover so that the rotation of the cover is delimited. ### Claim 8 (depends on 1) The seaming roll according to claim 1, wherein the fastener comprises a thread arranged on the rotation body and a counter thread arranged on the seaming profile. ### Claim 9 (depends on 7) The seaming roll according to claim 7, wherein the safety mechanism is a safety pin. ### Claim 10 (depends on 1) The seaming roll according to claim 1, wherein the first basic side or the second basic side is round. ### Claim 11 (depends on 1) The seaming roll according to claim 1, wherein the rotation body is a cylindrical rotation body and the seaming profile is a seaming profile ring. ### Claim 12 (depends on 1) The seaming roll according to claim 1, wherein the bearing is a ball bearing or a cylindrical roller bearing. ### Claim 13 (depends on 1) The seaming roll according to claim 1, wherein a seal is arranged between the cover and the rotation body to prevent leakage of lubricants from the bearing. ### Claim 14 (depends on 5) The seaming roll according to claim 5, wherein the cover is a symmetrical polygon. ### Claim 15 (depends on 5) The seaming roll according to claim 5, wherein the cover is an asymmetrical polygon. ### Claim 16 (depends on 1) A sealer comprising: the seaming roll according to claim 1. ### Claim 17 (depends on 16) The sealer according to claim 16, further comprising a clamping device. ### Claim 18 (depends on 16) The sealer according to claim 16, wherein the seaming roll is one of at least two seaming rolls.
