PURPOSE: To provide a method for forming a lubricating coating film on the surface of the dryer of a paper machine, a spraying apparatus therefor and a solid lubricant to form the lubricating coating film on the surface.

CONSTITUTION: A solid lubricant supplied from a chemical liquid tank and air supplied from an air controlling part are introduced into a nozzle unit 24 through a liquid pipe and an air pipe built in a cable bear 12 and mixed with each other in a nozzle of a spray unit 18 extended in the sprayer main body 27 placed at a distance of ≥5cm from the surface of a dryer. The mixture is atomized from the spraying hole 29 at the center of a cap 20 by the ejection pressure and the mist of the lubricant is sprayed to the surface of a paper machine dryer while traversing the nozzle unit 24 to form a lubricating coating film on the dryer of the paper machine. The chemical liquid spraying apparatus is composed of the chemical liquid tank 3, accessory apparatuses, the cable bear and a timing belt 14 or a caterpillar chain. The solid lubricant is composed of a solid lubricant, a dispersing agent, a binder and water.
