ABSTRACT:
A lattice of metal or plastics material obtained by stretching a blank or strip which has been provided with rows of slits. The lattice has rhomboid or rhomboidal openings which are bordered by webs which extend obliquely relative to the plane of the lattice. The major diagonals of the openings include an acute angle with the edge of the lattice. The major diagonals of the openings have such an angular position that two webs which extend parallel to one another also extend parallel to the edge of the lattice. The webs located in the same row which define openings arranged one behind the other in the direction of the lattice edge are arranged so as to follow each other immediately and at least approximately in a straight line.
