Abstract

(Fig.2) MANUFACTURE OF AN EXPANDED WEB OF SHEET MATERIAL A sheet of material is passed through meshing rotary shearing and forming dies to form rows of convolutions 16 which in each row are separated by an undeformed neutral zone N between each pair of adjacent convolutions. The rows are staggered so that the peak of a convolution in one row coincides with the troughs in adjacent rows and vice versa but the neutral zones coincide to maintain the integrity of the expanded web. The expanded web 12 can then be laminated to a plane sheet 11. The resulting structure is useful as a cigarette wrapper which is wrapped around a tobacco rod through which the longitudinal air flow is as shown by the arrow. The dimensions and periodicity of the convolutions can be adjusted to control air flow through the wrapper.
