Abstract
Abstract A resin radius roller for use in connection with resin impregnated fibrous materials which includes a shaft having a handle at one end and an axle, perpendicularly arranged, at the other end, and wheels having circular fins rotatably mounted on the axle on either side of the shaft, said fins decreasing in diameter as their distance from said shaft increases, said wheels being free to move laterally as well as with a rocking motion. The resin radius roller can be used in the corner of a mold to work air bubbles out of resinous materials without in any way catching or snagging the material being rolled.
