Abstract: A method for forming a convex tilting zone (23) at a main body-surface (11) of a transverse element for application in a push belt for a continuously variable transmission comprises the step of applying a die (30) that is placed against the main body surface (11) under pressure. However, the die (30) is pressed against the main body surface (11) just outside of an area where the tilting zone (23) needs to be formed. By applying the die (30), a recessed area (27) is arranged in the main body surface (11), wherein retraction of the material of the transverse element takes place along an upper edge (28) of this area (27). A retraction area that is obtained in this manner is suitable to function as tilting zone (23). An important advantage of the application of the described method is that the pressure that is exerted on the die (30) may be considerably lower than the pressure that is required during conventional processes for forming a tilting zone (23).
