Abstract: A laminating device for laminating a continuous web of paper material to a continuous web of film material for forming a continuous web of laminated composite material at a laminating nip. Apparatus for dividing the paper web into at least two segregated tension zones upstream of the laminating nip and for dividing the composite web into at least two segregated tension zones downstream of the laminating nip are described. Control systems for monitoring and maintaining the tension in each tension zone at different, preset values, are also described.
