Abstract
A material includes a sheet of metal having a first face and an opposed second face, and a metal grain direction. The first face is textured with a first set of texturing features. Each texturing feature of the first set includes, respectively, a groove cut into the first face and extending along a groove axis, and a barb extending from the groove and away from the first face. The texturing features of the first set are arranged in a plurality of rows, and the groove axes of the texturing features in a given row extend generally parallel to the given row. The rows are generally non-perpendicular to the grain direction.
Claims12
A process for producing a textured sheet of metal, the process comprising:
- a. feeding a sheet of metal into a texturing apparatus, the sheet of metal extending along a longitudinal axis and being fed into the texturing apparatus in a direction generally parallel to the longitudinal axis;
- and
- b. actuating a knife of the texturing apparatus to impact the sheet, the impact gouging at least one groove into the sheet and creating a barb with the material removed in creating the groove, wherein the knife is actuated towards the sheet and across the sheet in a direction that is generally non-perpendicular to the longitudinal axis.
A texturing apparatus comprising:
- a. a base for receiving a section of a sheet of metal, the base extending along a base axis between a metal receiving end of the apparatus and a metal dispensing end of the apparatus;
- b. at least a first knife mounted above the base, the first knife extending along a generally horizontal knife axis, and including a plurality of teeth that are spaced apart along the knife axis, the first knife moveable vertically towards the base and horizontally across the base;
- wherein the knife axis is generally non-perpendicular to the base axis.
