Simultaneous winding of tissue webs

摘要

A system and process is described for producing spirally wound products. According to the process of the present disclosure, two or more webs are conveyed together in a superimposed relationship. The webs are then separated such that one web goes to a first winding module while a second web goes to a second winding module, etc. In this manner, at least two spirally wound products can be produced simultaneously. The process and system of the present disclosure are particularly well suited for processing tissue webs, such as paper towels and bath tissue. The process of the present disclosure can effectively at least double throughput on existing winding systems.

主权项

1. A method for forming spirally wound rolls comprising:
placing a first tissue web on top of a second tissue web; conveying the first tissue web and the second tissue web downstream in a superimposed relationship; separating the first tissue web from the second tissue web and feeding the first tissue web to a first winding device and feeding the second tissue web to a second winding device; and winding the first tissue web on the first winding device and winding the second tissue web on the second winding device simultaneously to form respective spirally wound rolls.
