ABSTRACT:
A process and machine are provided for the formation of expanded mesh materials in which a slotted starting sheet is bent along at least one succession of alternate strand diagonals (1,2, 3, 4, 5; A, B, C, D), each strand (20) in any one diagonal being bent simultaneously in at least two positions in the same manner and to the same extent so that the strands (20) of the strand diagonal (1, 2, 3, 4, 5; A, B, C, D) being bent remain in substantially parallel planes during and after bending. A "strand" (20) is defined as the area of overlap between adjacent rows of slots (10) at each end of a respective slot (10) according to the slot pattern in the slotted starting sheet.
