Roller shutter profiles (10) made of plastic are usually foamed in a second subsequent manufacturing section. In order to be able to manufacture and foam the roller shutter profiles in one work section, the invention proposes first to extrude the roller shutter profiles (10) in a V-shaped intermediate position with a lateral opening, into which a continuous strand of foaming material is injected before the roller shutter profile (10) is closed by a continuous lateral snap connection (17). <IMAGE>
