Abstract
A device for heat treatment, in particular for steaming of spools, cops and cones, based on an elongated, height-adjustable steaming vessel (2), arranged below, and parallel to, spools (15) suspended in a row. By being moved into the steaming vessel (2), the spools (15) can be unlatched and, after closing of a lid (7), heat treated. Alternatively, a closed, conduit-like steaming vessel can be included in the material flow of the spools, permitting steaming in the throughfeed mode. The dwell times of the cops after steaming are largely predeterminable. Also, the space requirements of the equipment are minimal.
