STRUT AND METHOD OF MANUFACTURING A STRUT
A strut (I) comprising an elongated beam portion (2) and at least one connecting end portion (3), where the elongated beam portion (2) is a tubular structure having an external circumference (C), and the connecting end portion (3) is integral with the elongated beam portion (2) and is comprised of a folded and flattened end portion of the tubular structure, in which diametrically opposite inward fold lines (5) meet between flattened parts (3a, 3b) of the end portion of the tubular structure, so that the resulting connecting end portion (3) comprises four material layers, and where the connecting end portion has a width (w) in a direction transverse to a longitudinal centreline (L) of the connecting end portion, where w>CI 4, and a method (I 00) of manufacturing a strut (I) comprising the steps of providing (IOI) a tubular element (IO) having an external circumference (C) and forming (I02; I03) a connecting end portion (3) at an end of the tubular element (IO), wherein the connecting end portion is formed by folding (I02) and flattening (I03) a portion (3′) of the tubular element (IO), wherein the folding (I02) is performed by deforming the material in said portion (3′) so as to form inward fold lines (5), and pushing them from diametrically opposite sides in a direction (pI) toward the centre (X) of the tubular element until they meet, and the flattening (I03) is performed by pressing the thus folded portion (3′) toward the centre (X) of the tubular element, from opposite directions (p2) perpendicular to the direction of pushing (pI), whereby an end portion (3) comprising four material layers is obtained.
