Claim Text:
1. A roller with an eddy current brake, comprising: a tubular roller shell rotatably supported about an axis in a stationary bearing, an eddy current brake with a tubular eddy current receiver within the roller shell and fixedly connected thereto, a magnet stationarily connected with the bearing, having north and south poles arranged at a distance of an air gap from the eddy current receiver, and a shielding tube made of a ferromagnetic steel material formed between the roller shell and the eddy current receiver in a way projecting thereinto, the shielding tube being fixedly connected with the stationary bearing at an end thereof, the shielding tube being arranged at a distance of a second air gap from the roller shell and at a distance of a third air gap from the eddy current receiver, wherein the second and third air gaps are dimensioned sufficiently large so that a contact of the roller shell and of the eddy current receiver with the stationary shielding tube upon performance of the rotation is excluded.
