Apparatus for forming logs of web material and log manufacturing process

摘要

A log multiprocessing apparatus winds a web material (W) around a winding core to form a log (L1). Once the log (L1) is about to be completed, the web material (W) is severed to form a tail of the log, and a pattern including at least one glue layer is applied on the tail of the log. The log then is decelerated and the tail is pressed on the log to form a final sealed log of web material.
