Abstract
A method for applying hot melt adhesive powder onto a sole or shoe part includes the steps of applying a cleaning agent, irradiating, applying a conductive liquid which has a conductivity at least 100 times higher than purified water which has a conductivity of 5.5·10−6 S/m, spraying hot melt adhesive powder; and heating. The method can save energy, reduce the working space, reduce the labor intensity and improve the working environment by continuously carrying out the spraying and the melting operation of the hot melt adhesive.
