Abstract:
1. Method for producing a multi-ply web of flexible material, at a plurality of glue sites, which comprises: by gluing the plies bringing a patterned glue transfer roll, having a pattern of protuberances, in contact with a glue application device; transferring glue to a first web shaped flexible material in a glue pattern corresponding to the configuration of the protuberances; bringing a second web shaped flexible material in contact with the glue applied side of said first web shaped flexible material in a press nip between a patterned lamination roll and an impression roll; said lamination roll having a pattern of protuberances corresponding to said glue pattern; the glue transfer roll and the lamination roll being in register with each other, so that the first and second web shaped flexible materials are combined and glued together in a pattern corresponding to the configuration of the protuberances of the glue transfer roll, wherein the first web shaped flexible material is printed with a printed pattern by a printing roll carrying a colorant in a selected pattern, wherein the printing occurs before the first web shaped flexible material is laminated to the second web shaped flexible material and the printed pattern is printed on an inner side of the first web shaped flexible material facing the second web shaped flexible material; wherein said printing is performed in register with the glue transfer while the first web shaped flexible material is residing on said impression roll, and wherein the printing and the glue transferring are separate and discrete steps effectuated by separate structures.
