MULTILAYER TUBE OF THE TOBACCO INDUSTRY AND METHOD FOR MAKING THE MULTILAYER TUBE

A multilayer tube of the tobacco industry, which has an internally hollow cylindrical shape extending round a longitudinal axis (X) and having a multilayer thickness defined by at least two superposed layers (2, 3, 4), is obtained by winding a flat multilayer material (100) around the longitudinal a...

Beschreibung
Zusammenfassung:	A multilayer tube of the tobacco industry, which has an internally hollow cylindrical shape extending round a longitudinal axis (X) and having a multilayer thickness defined by at least two superposed layers (2, 3, 4), is obtained by winding a flat multilayer material (100) around the longitudinal axis (X) until juxtaposing and coupling to each other opposite lateral edges (110, 120) of the flat multilayer material (100), where the flat multilayer material (100) is obtained by folding a single sheet or web (50) about at least one fold line (P1, P2) parallel to the longitudinal axis (X) to superpose corresponding zones of the sheet or web (50) and define the multilayer thickness.
