摘要
Paper sheet or board is externally sized by applying to the surface thereof a rosin-based sizing agent in the form of a foam in the production of which the sizing agent itself acts as a foaming agent. After the foam has been applied to the surface of the paper sheet or board, at least a major proportion of the applied foam is mechanically broken down to provide a substantially uniform distribution of the sizing agent over the surface.
