A roller with an eddy current brake includes a roller shell that is rotatably supported in a stationary bearing, wherein the eddy current brake, within the roller shell, includes an eddy current receiver connected thereto and a stationary magnet. The eddy current brake is formed with a shielding tube made of a ferromagnetic material (steel), which at one end is fixedly connected with a carrier with the rod, the carrier being made of a non-magnetizable material (aluminum), wherein the shielding tube is arranged at a distance of a further air gap from the roller shell and at a distance of a further air gap from the eddy current receiver. By reason of the roller 5, one achieves that the start of the rotation of the roller shell 11 takes place without remagnitization and thus more smoothly. |
