The presented work deals with an analytical solution for a roll coater with deformable rolls, as commenly used in industry. The focus is on the calculation of the nip feed system in a forward coating mode. The calculation is done with thin film theory and includes Hook's law for elasticity for modelling the elasticity behaviour of the deformable roll. The new model has been validated by experimental data from literature. The agreement is sufficiently good. (© 2012 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
