Abstract

The assembly to guide and/or dry a moving web of paper or cardboard and the like, without contact, has at least one hollow jet beam (1) in a box shape, and charged with a gas. The beam dimensions match the width of the web (B), and has a number of blower jets (9) for the gas to be blown out towards the web and form a pressure cushion (D) between the web and the beam surface. At least one inner surface (2a-5a) of the beam walls (2-5) has an acoustic damping layer (7) using a mineral wool.
