ABSTRACT:
Process and device for drying paper webs, with the process being utilized for drying voluminous paper webs, destined in particular for use as toilet paper, with at least one heated press being used for drying the wet paper web, with the undesirable delamination of the paper web, when it leaves the compression gap, caused by the sudden expansion of the flash steam, being purposefully used in order to improve the volume and softness of the thus produced paper. Several devices are also set forth for implementing the process, these devices having both short and elongate compression gaps.
