Abstract (en)
A machine for making multilayer tubes of the tobacco industry comprises: a first folding station (3, 4) configured to fold a first longitudinal strip (110) of the continuous web (100) onto a second longitudinal strip (120) of the web (100) to obtain a multilayer web; a forming station (5) for forming a continuous tube by continuously wrapping the multilayer web around a longitudinal axis; a cutting station for cutting the continuous tube into a succession of tubes (200); wherein the folding station (3, 4) has a first deflector edge (10) for deflecting the first longitudinal strip (110) and a second deflector edge (11) to deflect simultaneously the remaining longitudinal strip (120, 130) of the continuous web (100), the first and second deflector edges (10, 11) being angled to each other.
