A method of and apparatus for laminating a first material (40) such as a spunbonded polymer having a point emboss pattern (41) formed thereon, to a second material (43) such as a polymer film, involves use of a lamination process using a point lamination pattern (56) provided on a heated calender roll (50). One or more geometric characteristics of the two patterns (41, 56) such as bonding/contact area, pitch, or angle of axes, is selected and differentiated, prior to lamination, to control, during lamination, the amount of point mis-registration between the two patterns (41, 56). The laminate (60) can have optimum all over lamination if the amount of point mis-registration is maximised. An adhesive can be provided between the first and second materials (40, 43) to enable lamination of dissimilar composition materials. |
