Abstract
An apparatus and method for cooling a melt strip from a wide-slot die includes a cooling roller driven at a predetermined angular velocity and juxtaposed with a corona-discharge electrode in the form of a rotation symmetrical rigid bar which is rotated about its axis at an angular velocity much greater than that of the cooling roller. The rotating corona-discharge electrode can be received in a nonrotatable insulating chamber having air inlets on a side opposite a slot-shaped outlet training ionized air onto the melt strip.
