Abstract: Elements with heads confronting each other are blanked out of two opposite sides of an elongated metal sheet. The differences between thicknesses of the elements at a measurement point at or near 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 laminated ring is manufactured by severing a cylindrical drum, which comprises a sheet of maraging steel with welded opposite ends, into a plurality of rings of predetermined width, rolling the rings to a predetermined target circumferential length, correcting circumferential lengths of the rings, aging and nitriding the rings, and laminating the rings into a laminated ring for transmitting power in a continuously variable transmission. A load applied to a circumferential edge of each of the rolled rings and a load applied to another circumferential edge thereof are measured while supporting an inner circumferential surface of the ring and applying a tensile load in a direction to expand the ring. The difference between circumferential lengths of the circumferential edges of the ring is detected based on the difference between the loads applied to the circumferential edges when the difference between the loads is maximum.

Abstract: Metallic tape is butt spliced, i.e. without overlapping the tape, by measuring a fine strip of silver solder into a gap between the cut edges of the lengths of tape being spliced in such a manner that the strip of solder extends over one of the lengths and under the other. The area being spliced is pressed between carbon electrodes and the silver solder is fused by the passage of resistance current.

Abstract: A method for producing a metal belt, in which the metal belt is ground at least on one side over essentially the entire surface. In a first step, a transverse curvature in the direction of the belt width is produced on the metal belt by straightening machining, wherein a first side of the metal belt is convexly shaped and a second side of the metal belt opposite the first side is at least planar or concave in shape, and in a second step, the course of the belt thickness in the direction of the belt width is changed to a uniform course of a value of the belt thickness.

Abstract: An inclined surface corresponding portion (30′) of a metal element raw material (23′) and inclined surface forming portions (47b, 47c) of dies (47, 49) are parallel to each other and are in contact with each other without gap. Therefore, a press load required while forming a metal element (23) is suppressed to a minimum and durability of the dies (47, 49) is enhanced. In addition, recess portions (24a, 26a) are formed on both rear surfaces of an ear portion (26) and a body portion (24) of the metal element (23) through pressing by using the dies (47, 49). Therefore, the sizes of both the recess portions (24a, 26a) are adjusted to change radially inward/outward distributions of the press loads on the dies (47, 49), so that it is possible to prevent the dies from tilting and to reduce a difference in radially inward/outward plate thickness of the metal element (23).
