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.
