Abstract

In a three-roller device for uniformly coating a moving web with small quantities of fluid, the middle roller is provided with a contoured or grooved elastic covering, one of the two other rollers with a smooth elastic covering and the third with an incised elastic covering or sheath. Fluid is transferred to the middle roller from the roller which is not in contact with the moving web, the fluid being introduced either via a pool on a trough or via a spraying apparatus.
