A circular spreader for spreading tubular textile goods includes a spreader arrangement with an inlet mandrel and an outlet mandrel at opposite ends thereof inside the tubular goods, an inlet support structure arranged around the inlet mandrel outside of the tubular goods with an inlet guide gap therebetween, and an outlet support structure arranged around the outlet mandrel outside of the tubular goods with an outlet guide gap therebetween. The mandrels and the support structures are magnetic, to magnetically repel each other across the guide gaps. The components may be permanent magnets or electromagnets, or have separate discrete magnets provided thereon. The spreader arrangement is supported by magnetic levitation relative to the support structures, without direct contact therebetween. The tubular goods pass through the guide gaps with low friction, no pressing force exerted thereon, and no impairment of the structure or quality thereof.
