ABSTRACT:
A method for can drying wet webs for tissue products to preserve web bulk includes, in one embodiment, restraining a partially dewatered wet web between a pair of sheet molding fabrics. The restrained wet web is processed over a plurality of can dryers to dry the wet web, for example from a consistency of at least about 40 percent to a consistency of at least about 70 percent. The sheet molding fabrics in this embodiment protect the wet web from direct contact with the can dryers and impart an impression in the web. A can drying assembly and tissue machine for accomplishing the method are also disclosed.
