AI Technical Summary

Technical Problem

Existing methods for processing tobacco webs with inserts, such as aromatic capsules or aromatizing threads, often result in damage or breakage of these inserts due to crimping or embossing processes, which are necessary for forming rods or improving filtration and liquid absorption.

Method used

A device and method that selectively process certain regions of the web without inserts, using a processing profile with reliefs and grooves to create crimping lines while avoiding or reducing processing in areas with inserts, ensuring the integrity of the inserts is maintained.

Benefits of technology

Optimizes the formation of tobacco rods by preserving the integrity of inserts and enhancing the quality of the web processing, allowing for high-quality production of semi-finished webs and rods.

Abstract

A device (100) for processing a continuous web (N) extending along a longitudinal direction (L) and comprising at least one insert (I). The device (100) comprises a processing profile (200) configured to act on at least one first longitudinal band (F1) of the web (N) so as to make a processing on the at least one first longitudinal band (F1) of the web (N). The device (100) further comprises at least one interruption zone (300) configured to create on the web (N), in particular at the insert (I), at least one second longitudinal band (F2) with reduced or no processing.
