Abstract (en)
According to a method for producing head elements for heaters, a piece of sheet metal (1) is deep drawn and cut along the edge (9) of an open side (6) to obtain a hollow body (8) with larger and narrower sides (4,5,14,15) with an aperture (12) on each opposite larger side (4,5). Notches (16, 46, 56) are made on the opposite large sides (4,5), and then three cores (18) are introduced through the edge (9), so that the edges (17, 47, 57) are press-shaped around the cores (18) so as to close the sheet metal (1) around the cores (18). After the cores (18) have been removed, a welding is made along the notch edges (17, 47, 57) thus obtaining tubular extensions (13) separated from each other.
