Abstract: The present invention discloses a process to produce staggered dent profiled material sheets in response to the application of either excess pressure or underpressure. A rectangular, staggered dent-profiled structure is achieved when a material sheet, in curved form, is supported by regularly spaced-apart support elements and then excess pressure or underpressure is applied. As a result of the pressure dents appear on the material sheet in the direction of the support elements as well as by self-organization. Hexagonal dent profiled structures are generated when flexible support elements are used. The dent profiling can result from a semi-continuous or continuous operation. Segment-wise dent profiling can be achieved when the material sheet is successively bent in peripheral direction over a segment of regularly spaced-apart support elements and then dent profiled under pressure.
