9 employed it eliminates from the layer s an amount of water sufficient to reach a degree of dry content which bestows on the web itself a mechanical resistance sufficient for being subjected to an action of embossing without undergoing any damage or tearing typically the layer s is dried to reach a degree of dry content comprised in the range of 60 wt to 90 wt i e up to a condition in which the dry content of papermaking fibers in the layer reaches 60 wt to 90 wt with respect to the overall weight of the layer the remainder being water the partially dried layer is detached from the drying cylinder 9 or other drying system for example via a fabric 11 associated to which is a suction chamber 12 set on the opposite side of the fabric with respect to the face thereof that comes into contact with the layer s of papermaking fibers downstream of the suction chamber 12 with respect to the direction of advance of the layer s there is set a pressure chamber 15 i e a chamber from which a flow of air at a slight pressure is emitted the pressure chamber 15 is set with respect to the fabric 11 on the same side as the chamber 12 the chamber 15 has the purpose of generating a current.
