Abstract
A formed sheet metal material and methods, tools and apparatus for forming the sheet metal material in which a pattern of projections and depressions are cold worked in a first portion and, simultaneously, indicia is embossed in a second portion of the sheet material. The cold worked portion is formed with the projections and depressions configured and distributed such that lines drawn on a surface of the formed sheet material between adjacent rows of projections and depressions are not rectilinear. The indicia is indicative of the alignment between the tools.
Claims21
A metal sheet material having a first major surface and a second major surface, the metal sheet material comprising a pattern of projections and depressions formed on both major surfaces and on or in a first portion or region of the metal sheet material and indicia formed on or in a second portion or region of the metal sheet material at an interruption in the pattern of projections and depressions, wherein the indicia has a form and the form of the indicia is usable to provide an indication of an alignment of tools used to form the pattern of projections and depressions, wherein the indicia comprise a plurality of individual alphanumeric characters at the interruption.
A metal sheet material having a first major surface and a second major surface, the metal sheet material comprising a pattern of projections and depressions formed on both major surfaces and on or in a first portion or region of the metal sheet material and indicia formed on or in a second portion or region of the metal sheet material at an interruption in the pattern of projections and depressions, wherein the indicia has a form and the form of the indicia is usable to provide an indication of an alignment of tools used to form the pattern of projections and depressions, wherein the indicia comprise a plurality of alphanumeric indicia, wherein the indicia is a name or a logo.
A metal sheet material having a length and a width, a first major surface and a second major surface, the metal sheet material comprising a pattern of projections and depressions formed on both major surfaces and on or in a first portion or region of the metal sheet material, the pattern of projections and depressions extending across the length and width of the metal sheet material and indicia formed on or in a second portion or region of the metal sheet material at an interruption in the pattern of projections and depressions such that the indicia is remote from any of the projections or depressions providing said pattern of projections and depressions, wherein the interruption is an area where there are no projections or depressions wherein the indicia has a form and the form of the indicia is usable to provide an indication of an alignment of tools used to form the pattern of projections and depressions.
A metal sheet material having a length and a first major surface and a second major surface, the metal sheet material comprising a pattern of projections and depressions formed on both major surfaces and on or in a first portion or region of the metal sheet material, a second portion or region where there are no projections or depressions to provide a first interruption in the pattern of projections and depressions, and a third portion or region where there are no projections or depressions to provide a second interruption in the pattern of projections and depressions and first indicia formed on or in the second portion or region of the metal sheet material and second indicia formed on or in the third portion or region of the metal sheet material, wherein the first interruption and the second interruption are successive interruptions along the length of the sheet material with projections and depressions between the first interruption and the second interruption and the first indicia and second indicia are the same and have a form and the form of the first and second indicia is usable to provide an indication of an alignment of tools used to form the pattern of projections and depressions.
