A device and a method are provided for the removal of liquid coolant or lubricant edge beads from the side marginal edges of a moving web, such as metal sheet or strip. The device consists of two or more pairs of manifolds, wherein the individual manifolds of each pair are positioned above and below the main surfaces of the moving web and the manifolds also extend beyond the side edges of the web. The manifolds are arranged at an angle to the side marginal edges of the web and compressed gas is introduced to the manifolds. The introduction of the compressed gas, such as air, through the manifolds provides vertical curtains of compressed gas parts of which impinge on the surfaces of the web and thus create turbulence at the side marginal edge portions where the liquid edge bead is located. Due to the turbulence created at the side marginal edge areas of the moving web effective removal of the liquid edge bead can be accomplished.
