Abstract
This invention relates to an improvement in an externally held cylindrical spreading means for tubular fabric, particularly for the treatment of the fabric with a fluid treating agent, with a central carrier for radially displaceable supports and segment-like guide elements carried by the supports, body means at each end of the central carrier, each of the body means being tapered in the longitudinal direction, and the guide elements extending in the longitudinal direction of the spreading means between the body means, the improvement comprising that the spreading means includes a pair of threaded sleeves mounted on opposite threads on the central carrier, radially-extending means with external magnetic pole means non-rotatably connected to the central carrier, and means for applying an external magnetic force on the magnetic pole means whereby the central carrier may be rotated.
