Abstract:
1. An apparatus for assembling at least two webs of tissue paper with or without marking of said webs, comprising a first embossing group with a rigid roller provided with embossing protuberances and a roller having a deformable coating which may be pressed against the rigid roller for embossing a first web of tissue paper by passing the first web between the rigid roller and the roller having a deformable coating, and a marrying roller, which is selectively applied against the rigid roller so as to marry the first web to a second web, the at least two webs being guided between the marrying roller and the rigid roller of the first embossing group, wherein the apparatus comprises an additional marrying roller, which is selectively pressed against the marrying roller so as to allow the assembling of the at least two webs of tissue paper by passing between the marrying roller and the additional marrying roller, wherein the assembling is without marking when the first web passes around the first rigid roller without the roller having a deformable coating pressing against the rigid roller and wherein the assembling is with marking when the first web passes around the first rigid roller with the roller having a deformable coating pressing against the rigid roller, wherein the apparatus further comprises a second embossing group for embossing the second web of tissue paper and a third embossing group and a marrying roller associated with the third embossing group, wherein the additional marrying roller is the marrying roller associated with the third embossing group.
