In the rollig method of the gears, the swell of the gear into two side : the direction of the two, the side swell alonge only dangerous in handling, but useless in practice.　A die roller holder used in this experiment was formed like a fork with a die roller fitted freely at one hand and a coller with a dovetailed groove around its periphery at the other hand.　The teeth of gear made by the die roller get into the groove of the coller, and the side swells of teeth are scraped off by both edges of the groove.　This experiment on the rolling of the elliptic gears was made on the assumption that the coefficient of the swell of the tooth at any point of the pitch ellipse is simlar to that of the cylindrical gear. But in this case, the radius of the pitch circle of the cylindrical gear is to be equal to the radius of curvature at that point of the pitch ellipse.
