Abstract

The problem addressed by the present invention lies in using a press moulding apparatus provided with a punch (11) a die (12) and a pad (14) which presses and confines a moulding material (13) against the punch (11) in order to produce a press moulded article (15) made of a steel sheet having a high tensile strength of 390 MPa or greater in which an outwardly oriented flange (16) is formed on an end part in the lengthwise direction said press moulded article (15) comprising a groove bottom part (15a) ridge parts (15b 15b) which are contiguous with the groove bottom part (15a) and longitudinal wall parts (15c 15c) which are contiguous with the ridge parts (15b 15b). When the moulding material (13) is press moulded the pad (14) confines a portion of the moulding material (13) which is moulded in the groove bottom part (15a) and a portion thereof having a length of at least one third of the peripheral length in cross section of the ridge part (15b) from the portion which is moulded in the ridge part (15b) in the vicinity of the outwardly oriented flange (16) taking the connection with the groove bottom part (15a) as the starting point. As a result the press moulded article (15) can be reliably moulded without a cutaway being provided in the ridge part flange portion of the outwardly oriented flange and without any reduction in material yield occurring.
