Title:
METHOD FOR MANUFACTURING A METAL RING FOR A RING SET OF A DRIVE BELT FOR A CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2020/135928
Kind Code:
A8
Abstract:
The invention concerns a method for manufacturing a metal ring (41) for a ring set of a drive belt for a continuously variable transmission, wherein the metal rings (41) are individually extended in their circumference direction, while their thickness is being reduced, in a rolling process step. After rolling the metal rings (41) are processed further and a number of thus processed metal rings (41) are mutually nested to form the ring set. According to the invention, after the said number of metal rings (41) have been rolled, but before these are nested to form the ring set, the metal rings (41) are turned inside out in a novel, additional process step (NFS).
