Document Type and Number:
WIPO Patent Application WO/2014/167632
Kind Code:
A1
Abstract:
To limit the occurrence of variations in the length of endless metal rings, the CVT belt manufacturing method comprises: a first drawing process (p1) for extending the circumference of an endless metal belt (110) by widening the distance between rollers; a measurement process for measuring the amount (Sb1) of spring back of the endless metal belt (110) in the first drawing process (p1); a calculation process for calculating a predicted spring back amount (Sb2) predicted from the measured spring back amount (Sb1); and a second drawing process (p2) for working the endless metal belt (110) to the specified circumference by further widening the distance between the rollers on the basis of the predicted spring back amount (Sb2) and drawing the endless metal belt (110).
