Abstract: A metal ring loading and unloading apparatus is capable of loading and unloading a metal ring quickly and highly accurately for increased efficiency. The metal ring loading and unloading apparatus has a moving unit 41 slidably movable along a rail 48 which extends from a loaded ring placement unit 8 to an unloaded ring placement unit 11. On the moving unit 41, there are mounted a loaded ring delivering unit 9 for holding and delivering a metal ring W on the loaded ring placement unit 8 and an unloaded ring delivering unit 10 for removing the metal ring W from support rollers 3, 4 and delivering the metal ring W to the unloaded ring placement unit 11. The loaded ring placement unit 8 has a pressing unit for radially pressing the metal ring W to deform the metal ring W into a substantially elliptical shape. The loaded ring delivering unit 9 has a loaded ring gripping unit 26 for gripping the metal ring W deformed by the pressing unit. The unloaded ring delivering unit 10 has an unloaded ring gripping unit 53 for gripping the metal ring W under its own recovering resiliency produced when the support rollers 3, 4 move toward each other. The unloaded ring placement unit 11 has a releasing unit for releasing the metal ring W from the unloaded ring gripping unit 53.

Abstract: Elements with heads confronting each other are blanked out of two opposite sides of an elongate metal sheet. The differences between thicknesses of the elements at a measurement point at or nearly at necks of the elements and measurement points at ears of the elements are averaged, and a distance between corners of the metal sheet and a counter load of counter punches are established in order to keep the averages in an allowable range. When elements are blanked out of the metal sheet with the distance and the counter load thus established, even if the metal sheet is laterally displaced out of position, a belt assembly made up of the elements blanked out of the two opposite sides of the metal sheet and mixed at a ratio of about 1 to 1 poses no problems because variations in the thicknesses of the elements blanked out of one of the two opposite sides of the metal sheet and variations in the thicknesses of the elements blanked out of the other of the two opposite sides of the metal sheet cancel each other.

Abstract: A high strength steel belt having an excellent flatness and a duplex structure of austenite and martensite has been prepared by a process which comprises providing a cold rolled or cold rolled and annealed strip of a martensitic structure from low carbon martensitic stainless steel containing from 10 to 17% by weight of Cr and having a carbon content of not exceeding 0.15% by weight, connecting ends of the strip or ends of a plate cut from said strip to provide an endless belt, causing the endless belt to circularly move between rolls under tension and to pass through a heating furnace where the belt is heated to a temperature within a range from (As point of the steel+30.degree. C.) to Af point of the steel and not higher than 900.degree. C. so that a part of the martensitic phase may be changed to a reversed austenitic phase and a desired surface flatness may be obtained after cooling.

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.
