FIELD: plastic working of metals, in particular, hot strip winder drums used in sheet rolling. SUBSTANCE: winder drum has casing having set of similar disks fitted onto shaft with draw key. Each disk has two wedge-shaped slots positioned in symmetry with respect to diametral axis. When disks are mounted on shaft, wedge-shaped slots are joined to define two openings adapted for receiving strip and arranged on drum generatrix, with angular distance of 180 deg between them. Such construction reduces temperature stress occurring due to temperature difference in furnace and, as a result, improves strength of drum. EFFECT: enhanced reliability in operation, increased service life, improved operation and repair conditions. 2 dwg
