Abstract: In a tissue paper making machine, a method for dewatering a tissue web without wet pressing and transferring the web onto a flow through drying cylinder including conducting a tissue web onto a pick-up fabric formed of felt and dewatering the web, without wet pressing, into the pick-up felt through the application of suction and capillary forces until the web has sufficient dry matter content to be passed to a flow through drying cylinder. The web is transferred to a flow through wire which passes over the web carrying pick-up felt at a suction roller by the application of suction over a narrow zone, the web being secured to the flow through wire by the application of additional suction over a broader suction zone.

Abstract: A method and apparatus in a paper making machine for transferring a web from a pick-up fabric to a flow-through drying wire for transport of the wire supported web to a flow-through dryer cylinder including passing a section of the flow-through drying wire over the web supported by the pick-up fabric thereby defining a sandwich structure of the drying wire, the web and the pick-up fabric. A first vacuum is applied by a first vacuum member on the sandwich structure from the flow-through drying wire side over a narrow first detaching zone. The direction of the pick-up fabric with respect to the flow-through drying wire is deviated and a second vacuum is applied by a second vacuum member over a second detaching zone subsequent to the first detaching zone in the direction of web travel from the drying wire side thereof thereby securing the web on the flow-through drying wire. The pick-up fabric may thus comprise either a felt or wire structure.
