In manufacturing two-sided laminated cardboard (1) in a laminating apparatus (10), by controlling band tensions of a first outer layer (11) and a second outer layer (12), a torque difference between an exerted first torque (Q1) in an upper roller (21) and an exerted second torque (Q2) in a lower roller (22) is controlled towards a pre-determined value (ΔQ) of said torque difference, while at the same time a torque addition sum of the first torque and the second torque is controlled towards a pre-determined constant value (Q) of said torque addition sum. Thus the invention provides an effective and reliable solution for counteracting concaveness or convexness, in the conveying direction (MD), of the two-sided laminated cardboard (1) to be manufactured.
