Definitions

  • Koch discloses a foraminous sheet having a relief pattern comprising a plurality of spaced-apart concave sections disposed in a regular array or grid or intersecting rows or columns.
  • Each of the concave sections has a truncated pyramid shape and is connected to neighbouring concave sections by further concave sections of semi- cylindrical shape.
  • foraminous sheets have a 0 surface texture that is often far from planar and that, accordingly, defines a relief pattern of sorts.
  • the present invention is not concerned with surface texture but rather with the overall shape or configuration of a sheet. Accordingly, the invention contemplates foraminous sheets having a shape or configuration that may be described as embossed, contoured, dimpled, ridged or undulating. The invention also contemplates combinations of these shapes or configurations; for example, a sheet may have a dimpled portion and a ridged portion.
  • the raised and/or depressed regions are suitably disposed in two-dimensional arrays, being either regular, irregular or random arrays.
  • the arrays may be linear (straight or curved), annular, spiral or concentric, and may be in straight or staggered relation to one another.
  • the invention also contemplates several methods for making a foraminous sheet with a relief pattern.
  • the relief pattern may be created as the sheet itself is created; for example, as a result of the knitting or weaving process adopted to make the sheet.
  • the relief pattern may be applied to a sheet after the sheet has been created; generally, this involves plastically deforming an otherwise flat sheet with a press, thereby to produce an embossed surface with the desired relief pattern.
  • a press to deform the foraminous sheet may take many forms.
  • the press comprises cooperable press members between which at least a portion of the sheet is pressed, at least one of the press members having a surface shaped to impart a desired relief pattern to the sheet.
  • part-spherical hills and hollows are formed: a variety of shapes may be formed by the apparatus, provided that the rollers 32 are adapted accordingly. Further, it is not essential that the hills and hollows alternate. Indeed, by providing only indentations in one roller 32 and only protrusions in the other roller 32, a series of only hills or only hollows will result.
