摘要： 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.

摘要： The invention relates to a push belt (3) for a continuously variable transmission where the belt (3) is partly clamed between sheaves (4, 5) of a pulley (1, 2) of the transmission that comprises an endless tensile means (31) and a multitude of plate-like transverse elements (33) that are provided on the tensile means (31) oriented predominantly transversely thereto and movable along its longitudinal direction, which elements (33) each show locking means (39, 40; 50, 51) for limiting a relative movement in either transverse or axial direction between two adjacent elements (33), i.e. an axial play DX, which is at most equal to the square of the element's dimension in the longitudinal direction Tact divided by the element's dimension in the axial direction Wact.

摘要： The invention relates to a transverse element (16) for a drive belt (3) comprising a body part (10), a neck part (11) connected to the body part (10) and a head part (12) connected to the neck part (11), which head part (12) is provided with a projecting boss (6), whereby a front main face of the transverse element (16) incorporates three minimally thickened contact regions (15, 14; 18) intended for contacting a rear main surface of an adjacent element (16) in the belt (3), whereof two lower contact regions (15) are arranged most laterally on the body part (10) near the bearing surfaces thereof and one upper contact region (14; 18) is arranged above the projecting boss (6) on the head part (12) near an upper edge thereof. An upper edge of the head part (12) extending in an essentially lateral direction over at least the lateral width of the projecting boss (6), preferably in a straight line, but possibly convexly or concavely curved at a radius of 10 mm or more.

摘要： A mould (70), which is designed to be applied for the purpose of a blanking process in which a transverse element which is designed to be part of a push belt for a continuously variable transmission is blanked out of basic material, has a receiving space (46) which serves for receiving the transverse element during the blanking process. Furthermore, the mould (70) comprises three separate mould components (71, 72a, 72b) for delimiting the receiving space (46). In comparison with the manufacturing process of an undivided mould, the manufacturing process of the mould (70) having the mould components (71, 72a, 72b) is simple, because in the latter case, the relatively complex shape of the receiving space (46) is obtained by simply positioning the mould components (71, 72a, 72b) with respect to each other in the proper way.
