ABSTRACT:
A method for obtaining wrapper sheet blanks from a continuous web having opposite parallel edges, wherein each blank is composed of first and second portions, the first portion having the shape of a rectangle and the second portion having the shape of a non-rectangular parallelogram joined to the first portion along a common imaginary edge. The method includes making a plurality of first cuts in the web which are spaced apart from each other in a direction parallel to the opposite parallel edges of the web, each first cut producing a first cut edge which is perpendicular to, and contiguous with one of the opposite parallel edges of the web and wherein each first cut edge constitutes an edge of a respective one of the first portions of the blanks; and making a plurality of second cuts in the web which are spaced apart from each other in a direction parallel to the opposite parallel edges of the web, each second cut producing a second cut edge which is inclined relative to, and contiguous with both a corresponding one of the first cut edges and the other of the opposite parallel edges, and wherein each second cut edge constitutes an edge of a respective one of the second portions of the blanks.
