摘要： 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.

摘要： The invention relates to a method of production for attachment by cohesive bonding of a profile having at least one profile element onto a toothed belt previously produced as a semi-finished product. The toothed belt has a tooth side with a toothing and a toothed belt back located on the back of the tooth side of the toothed belt. In the method of production the at least one profile element is built up layer by layer from at least one first profile element layer and a second profile element layer on the toothed belt back, by the application of an application compound to the toothed belt back at a profile element position by melt layer printing.

摘要： A metal element for continuously variable transmission and method of producing the same are provided. A rear surface of a metal element includes first contact parts formed at top positions on the outer side in the radial direction of a saddle surface on left and right sides of an ear part, a second contact part formed in a neck part, and third contact parts formed at a top position of the saddle surface on left and right sides of the body part. In a chord on the driving force transmission side of the metal belt, the first to third contact parts are able to be brought into contact with a front surface of another metal element adjacent to the rear side. A plate thickness of the metal element at the second contact part is smaller than the first contact part and is larger than the third contact part.

摘要： A method for manufacturing a metal element includes performing press processing and punching processing on a band plate-shaped metal element material having a constant cross section by a mold with a main punch in contact with a rear surface of the metal element and a counter punch in contact with the front surface thereof. The main punch or the counter punch has protrusion portions which are in contact with at least a part of the ear portion or the body portion to form a recessed portion, and a bulging portion bulging in the longitudinal direction from the radial direction inner edge of ear portions of the metal element or the radial direction outer edge of a body portion thereof, which is formed by the material extruded from the recessed portion by the protrusion portion.

摘要： Disclosed is a method for manufacturing an element for a CVT belt, comprising a body portion (22L, 22R) having right and left sides and a tapered portion with a downwardly reducing width, a neck portion extending upward from the body portion, and a head portion extending upward from the neck portion. The manufacturing method comprises a first punching step in which a metal strip blank (31) which has a uniform thickness and a width which makes it possible obtain elements arrayed on an even number of lines in an arrangement in which the head portions are opposed to each other or an arrangement in which the body portions are opposed to each other, is punched along an outline ((33L, 33R) of an excess material (21b) added to profiles of the left and right sides (21L, 21R) of the body portions, and along an outline (58L, 58R) of an excess material (32b) added to a profile of a lower side (32L, 32R) of the body portion; a plastic deformation step in which the blank is compressed in the thickness direction to form a predetermined projection and depression, and form the tapered portion while displacing the material in the outline directions; and a second punching step in which the element is obtained as a product by punching the blank.
