A stratified tissue web, such as is useful for facial or bath tissue, is formed by couching together two separately, formed webs at machine speeds of about 2000 feet per minute (609.6 metres per minute) or greater to provide a tissue web having equivalently soft surfaces on both sides of the tissue. The webs are laid as slurries by respective headboxes (1, 10) on wires (2, 11), suction is applied (at 20) and drying takes place on a Yankee dryer (30). Alternatively, hot air through-drying may also be used. <IMAGE> |
