Abstract: A method for removing liquids from the surface of a strip, characterized in that the liquid is excited in such a way that it oscillates. The invention is based on the recognition that the root of the problem of removing liquids from the surface of a strip lies in the adhesion forces and that these adhesion forces can be overcome by exciting the liquid in such a way that it oscillates. Its oscillation causes the liquid to detach itself from the surface of the strip and it can then be easily carried away, for example by suction by means of low pressure, blowing or stripping by means of a stripper.

Abstract: A wire feed amount detection mechanism is configured by magnets mounted at an outer peripheral surface of a V-grooved drive gear of a wire feed mechanism and a magnetic sensor mounted on a body. A reinforcing bar winding turn number-setting switch is provided on the body.
