Abstract

An improved method for coating fibers, for example, glass fibers, which are used in reinforcement webs for objects under high strain e.g. in grinding discs. The fibers are subjected to a two stage coating. In the first stage the fibers are coated with a liquid resin or resin solution. In the second stage resin in powdered form is deposited on the fibers. Thereafter, the fibers are subjected to a heat treatment. The products obtained are tacky to the touch and are used in this state in other mixtures of resinous binders and the like so that a good contact is made between the reinforcing material and the additional binder.
