Abstract
Abstract Into the inner surface of a cylindrical lens mount grooves are pressed by means of a roller member so that the material on either side of the groove folds from the general level of the surface into the interior space and form rolls. The diameter between the rolls is then sized to the exact size and the lenses, lens elements and pre-mounted lenses are supported on the rolls.
