Abstract
Abstract The hollow profile (10) consists of a bent sheet-metal strip (20), the longitudinal edges (30, 32) of which are interconnected by means of a fold (34) in such a manner that one side of the fold delimits a longitudinal groove (36) provided for receiving a sealing strip. The longitudinal groove (36) is formed by an outwardly open, widened joint of the fold (34). Such a profile, which can be manufactured by edging work, is in particular suitable for manufacturing small quantities. <IMAGE>
