Abstract: A method is disclosed for obtaining an exact fitting of a plurality of endless metal bands one into the other so as to form a belt package. Each endless belt is obtained as a section from a thin seamless tubing or by welding against each other the ends of a metal strip. Though the closed bands may be shaped with different diameters they will only fit around each other with some play. According to the new method the package is arranged on an expansible template which is then expanded to an extent by which each of the bands is elongated and any play between them is removed and the package is exposed to a tempering treatment preferably when the package is still under tension on the template. The bands are preferably elongated to a degree within the limit of elasticity and belt packages with mutual identical dimensions are obtained by simultaneously treating them side by side in equally dimensioned parts of one template.
