Unwinders

Reel unwinding is the first phase of the converting process. The reel is raised by lifting arms and placed inside the unwinder, on the unwinding belts.
The web is kept in tension, thus allowing its correct passage to the downstream converting stations.

Embossers

The embosser compresses the web between two rolls, one of which is steel and bears a pattern that is transferred through pressure onto the web. The aim of this process is both functional and decorative: the plies can be embossed with a dedicated pattern to yield bulk and softness.
Embossing is also a means for product personalization.
A light film of glue can be added to the embossing process.

Printing Units

In this converting phase the web passes through rolls bearing a cliché which allows to print patterns, logos or words for further product personalization.

Rewinders

This is where the most important phase of converting takes place.
The web is rewound in order to form the log that has the width of the parent reel and the diameter of the final product.
Other important functions carried out by the rewinder are: the perforation of the paper at pre-determined intervals in order to obtain the so-called sheet count in the finished roll; the control of the number of sheets contained in each log; the attainment of the pre-determined log diameter.

Accumulators

The log accumulator is an intermediate log deposit to be positioned between the rewinder and the log saw: it compensates for the difference in production rates between the upstream and downstream machinery. It receives the logs coming from the rewinder and accumulates them, thus allowing the rewinder to work continuously.

Tail Sealers

The tail sealer positions the final tail of the log, coming from the rewinder, and seals it with a thin layer of glue.


Log saws

This machine cuts the logs to the required length. The cut rolls are then sent to the packaging units.

Core makers

This machine produces the core, i.e., the cardboard tube on which the paper is wound. The cardboard strips are wound spirally and glued on each other.
