Zusammenfassung:A process for producing tissue webs is disclosed. In particular, the process is directed to transferring a wet web from a transfer surface to a separate conveyor, such as a fabric. The process, in one embodiment, may include the steps of partially dewatering a tissue web, subjecting the web to at least one deflection against a fabric, such as a coarse fabric, and then creping the web. During the process, after being dewatered, the tissue web is transferred from a transfer surface to the fabric while subjecting the wet tissue web to temperatures and pressures sufficient to cause gases to evolve from liquids associated with the web. The gases form in between the tissue web and the transfer surface facilitating transfer of the web onto the fabric. In one particular embodiment, for example, gases are evolved by heating the wet web and then subjecting the web to a suction force. The gases that are evolved from the liquid include gases that were dissolved in the liquid and may include vapors that are also formed during the process, such as water vapor.
