Abstract
An elongate profile having a first portion and a second portion, the first and second portions being joined together at a first joining portion, the first and second portions being non collinear, the joining portion comprising an array of raised or rebated formations, each formation extending across the joining portion in a direction which is non-parallel to the principal axis of the profile and flat lands being provided between successive formations in an array and the pitch between successive formations in an array being from 2 to 20 times, for example from 5 to 15 times, the thickness of the flatlands.
Claims22
A pair of rolls for forming a pattern on sheet material, the first roll comprising a first forming portion for forming at least part of a first pattern on a sheet material and a second forming portion for forming at least part of a second pattern on the sheet material, the first forming portion comprising a first array of projections and the second forming portion comprising a second array of projections, the second roll comprising a third forming portion for forming at least part of said first pattern on the sheet material and a fourth forming portion for forming at least part of said second pattern on the sheet material, the third forming portion comprising a third array of projections and the fourth forming portion comprising an array of rebates, the second forming portion and the fourth forming portion being co-operable to emboss a pattern corresponding to the respective array of projections and rebates on the sheet material and the first and third forming portions are co-operable to cold work harden the sheet material to form an array of projections and depressions with each projection on one side of the sheet material corresponding to a depression on the other side of the sheet material wherein the third and fourth forming portions have distinct shapes, such that, in use, the first pattern and the second pattern formed on the sheet material are distinct, and wherein one or both of the first roll and the second roll are formed in one piece as a unitary article.
A channel section having a base portion and a first side portion and a second side portion, the base portion being joined to the first side portion at a first joining portion, the base portion being joined to the second side portion at a second joining portion, the base portion being non collinear and non coplanar with respect to the first and second side portions, the first side portion being parallel to the second side portion, and the first and second joining portions and each comprising an array of embossed raised projections that extend outwardly, the channel section formed by a pair of rolls for forming a pattern on sheet material, the first roll comprising a first forming portion for forming at least part of a first pattern on a sheet material and a second forming portion for forming at least part of a second pattern on the sheet material, the first forming portion comprising a first array of projections and the second forming portion comprising a second array of projections, the second roll comprising a third forming portion for forming at least part of said first pattern on the sheet material and a fourth forming portion for forming at least part of said second pattern on the sheet material, the third forming portion comprising a third array of projections and the fourth forming portion comprising an array of rebates, the second forming portion and the fourth forming portion being co-operable to emboss a pattern corresponding to the respective array of projections and rebates on the sheet material and the first and third forming portions are co-operable to cold work harden the sheet material to form an array of projections and depressions with each projection on one side of the sheet material corresponding to a depression on the other side of the sheet material, wherein the first and second forming portions have distinct shapes, wherein one or both of the first roll and the second roll are formed in one piece as a unitary article, and wherein the third and fourth forming portions have distinct shapes.
A pair of rolls for forming a pattern on sheet material, the first roll comprising a first forming portion for forming at least part of a first pattern on a sheet material and a second forming portion for forming at least part of a second pattern on the sheet material, the first forming portion comprising a first array of projections and the second forming portion comprising a second array of projections, the second roll comprising a third forming portion for forming at least part of said first pattern on the sheet material and a fourth forming portion for forming at least part of said second pattern on the sheet material, the third forming portion comprising a third array of projections and the fourth forming portion comprising an array of rebates, the second forming portion and the fourth forming portion being co-operable to emboss a pattern corresponding to the respective array of projections and rebates on the sheet material and the first and third forming portions are co-operable to cold work harden the sheet material to form an array of projections and depressions on both sides of the sheet material with each projection on one side of the sheet material corresponding to a depression on the other side of the sheet material, wherein each of the first roll and the second roll are formed in one piece as a unitary article.
A pair of rolls for forming a pattern on sheet material, the first roll comprising a first forming portion for forming at least part of a first pattern on a sheet material and a second forming portion for forming at least part of a second pattern on the sheet material, the first forming portion comprising a first array of projections and the second forming portion comprising a second array of projections, the second roll comprising a third forming portion for forming at least part of said first pattern on the sheet material and a fourth forming portion for forming at least part of said second pattern on the sheet material, the third forming portion comprising a third array of projections and the fourth forming portion comprising an array of rebates, the second forming portion and the fourth forming portion being co-operable to emboss a pattern corresponding to the respective array of projections and rebates on the sheet material and the first and third forming portions are co-operable to cold work harden the sheet material to form an array of projections and depressions with each projection on one side of the sheet material corresponding to a depression on the other side of the sheet material, wherein the first and second forming portions have distinct shapes, wherein one or both of the first roll and the second roll are formed in one piece as a unitary article, and wherein the third and fourth forming portions have distinct shapes.
