During the blanking process of a transverse element for a push belt for a continuously variable transmission, use is made of, among other things, a supporting member for supporting the transverse element and a mould (45) having a receiving space for receiving the supporting member and forming a circumferential surface of the transverse element. Parts of an inner surface of the receiving space are provided with a relief (71) having alternating ribs (74) and grooves (72) , which serves for forming a similar relief on parts of the circumferential surface of the transverse element . Top parts (75) of the ribs (74) are substantially flat, so that a good guidance of the supporting member is obtained during the blanking process of the transverse element, and the formation of the transverse element takes place in an accurate fashion.
