Abstract
A sheet material for producing packages of food products and having a succession of optically detectable register mark; each mark, has a first and a second segment parallel to each other and perpendicular to a feed direction of the material, and a sloping segment interposed between the parallel segments, so as to define a broken, to substantially Z-shaped line, which may be used to determine the position of the material both in the feed direction and in a perpendicular direction.
