An embossing and laminating machine is described which comprises a first embossing cylinder (3) with a surface provided with a first set of protuberances (P3) disposed with a first pitch in a first direction (Lx.sub.3) of alignment and with a second pitch in a second direction (Ly.sub.3) of alignment, the said first and the said second direction of alignment forming between them an angle (.alpha.) other then zero; a second embossing cylinder (5), with its axis (A5) parallel to the axis (A3) of the first embossing cylinder (3), and with a surface provided with a second set of protuberances (P5) disposed with the said first pitch in a third direction (Lx.sub.5) of alignment and with the said second pitch in a fourth direction (Ly.sub.5) of alignment; and a first and a second pressure roller (7, 9) interacting with the said first and the said second embossing cylinder (3, 5) respectively. The first and the third direction of alignment (Lx.sub.3) are inclined with respect to the axes (A3, A5) of the corresponding embossing cylinders (3, 5) such that, in the lamination nip, there is only partial corresponding between the protuberances of one cylinder and the protuberances of the other cylinder.

[ What is claimed is:] [1.]1. An embossed sheet product comprising at least two layers which are embossed separately and glued together, each of said two layers having the same embossed pattern consisting of a plurality of protuberances disposed in a repeated geometrical pattern in two directions of alignment forming an angle other than zero between them, wherein the directions of alignment of said protuberances of a first layer are inclined with respect to the corresponding directions of alignment of said protuberances of a second layer, less than all of said protuberances of said first layer and of said second layer being in contact with each other, and the pitch of the pattern of protuberances of said first layer and said second layer are equal.
