ABSTRACT:
The invention relates to a method and an apparatus for the recovery of spraying substance when spraying elongated rolled stock. Difficulties are met when trying to recover water-dilutable or water-soluble coating agents since after evaporation of the solvent, i.e. the water, the film which is left can no longer be dissolved by water and thus it is no longer possible to recover this fraction of the spraying substance. According to the invention, therefore, it is proposed to carry out the spraying in a water-saturated atmosphere so that the excess spraying substance can easily be recovered. The apparatus is appropriately constructed to correspond to these circumstances.
