Definitions
- This invention relates to the processing of metal strip to raise longitudinal ridges along an intermediate portion thereof and to the metal strip per se.
- the invention provides a method of raising longitudinal ridges in an intermediate portion of metal strip by a rolling operation in which a metal strip is passed through a grooved roll and metal is displaced perpendicular to the plane of the strip and perpendicular to the rolling direction along one surface of the strip to form ridges.
- a metal strip is passed through a grooved roll and metal is displaced perpendicular to the plane of the strip and perpendicular to the rolling direction along one surface of the strip to form ridges.
- the width of the flattened marginal portion and the raised portion of the strip be substantially the same and that the difference in cross-sectional area between the flat marginal portion and the portion of the strip that includes the raised portion is equal to the area of the raised portion that extends above a fiat plane which extends parallel to the strip and includes the surface of the flattened marginal portions.
- FIG. 1 is a side elevation of a metal strip being passed through a roll assembly
- FIG. 2 is an enlarged cross-section of one form of metal strip of the invention.
- FIG. 3 is an enlarged cross-section of a second form of metal strip.
- a flat strip 10 is fed through a grooved roll assembly 11 which is comprised of an upper grooved roll 12 and a lower roll 13 not grooved.
- the strip is a flat brass strip of nominally .026" thickness by 5 wide and is being rolled to place longitudinal intermediate sharp ridges along one surface for the purpose of providing electrical contacts which take the form of serrations and can penetrate the insulation on magnet wire when crimped so as to splice together several magnet wires.
- the flattened marginal portions 15, 15' and the raised portions 16, 16' are of substantially the same width so that the difference in cross-sectional area between the flattened marginal portion 15, 15' and the portion of the strip which includes the raised portion 16 will be equal to the area of the raised portion which extends above a flat plane which extends parallel to the strip and includes the surface of the flattened marginal portion 15 and in the embodiments shown would include the surface of flats between the longitudinal ridges.
- the intermediate raised ridges 14, 14 also preferably extend above the raised portion 16, 16' where the longitudinal ridges are to serve as contacts.
- the raised ridges 14 are relatively sharp and are suitable for penetration of thin insulating coatings, whereas the ridges 14 of FIG. 3 are rounded and to be suitable for penetration of insulation they should be skived or otherwise sharpened.
- a method of raising longitudinal ridges in an intermediate portion of metal strip by a rolling operation in which a metal strip is passed-d through a grooved roll and metal is displaced perpendicular to the plane of the strip and perpendicular to the rolling direction along one surface thereof to form the ridges comprising flattening the marginal edges of the strip during rolling of the ridges and Etorming relatively broad longitudinal raised portions which are raised above the flattened marginal portion between the flattened marginal edges and the adjacent intermediate raised ridges on both sides of the strip which guide the strip during rolling to promote strip straightness and metal flow along the intermediate portion into the grooves of the roll is eflected.
- a flat metal strip comprising sharpened longitudinal ridges in an intermediate portion of a strip, flattened marginal edges along both side edges of the strip, and two broad longitudinal raised portions which are raised above the flattened marginal portions between the flattened marginal edges and the adjacent intermediate ridges on both sides of the strip.
