Methods for making and processing high bulk tissue webs

摘要

A method of splicing tissue webs comprising partially unwinding a first tissue web from a first parent roll (Rx) using electric drive means, transporting the first tissue web to a finishing unit (23) comprising rolls defining a finishing unit nip and thereafter substantially continuously impacting the first tissue web in the finishing unit nip while the first tissue web is unwound from the first parent roll using electric drive means. A second tissue web is then partially unwound from a second parent roll (R) using electric guide means and the second tissue web is then transported to the finishing unit. The first and second tissue webs (Te,Le) are maintained moveable relative to one another upstream of the finishing unit (23). The first and second tissue webs (Te,Le) are then simultaneously unwound from the first (Rx) and second (R) parent rolls using electric drive means and the webs are passed through the finishing unit (23) nip to bond the webs together. The second tissue web (R) is then substantially continuously impacted in the finishing unit (23) nip while the second tissue web (R) is unwound from a second parent roll using the electric drive means. Preferably, the finishing unit (23) comprises an embossing unit, a calendering unit or a crimping unit.
