A method of treating a metallic cord to improve its ability to adhere to rubber is disclosed. The method involves contacting the metallic cord with a naphthenic oil containing from 1 to 53 percent by weight of a soluble cobalt salt and thereby deposit from 0.002 to 0.7 grams of cobalt per kilogram of steel to the metallic cord.

Method of treating metallic cord

The invention provides an apparatus and method which can be utilized to apply a thin layer of viscous coating material to an elongated continuously moving filament whereby the filament can be cabled, coated, and spooled in a continuous operation. The apparatus has a coating material applicator to deliver a flowable material, an air applicator to supply compressed air, a mixer to mix the flowable material and compressed air, a delivery means to spray the mixed flowable material and air onto a filament, and a coating chamber through which the filament passes. The chamber has a material collector and a coating die, and a sealing attachment with an exit hole is located beneath the coating chamber. The filament is sprayed before it travels into the material collector.
