    Abstract: Machine for trimming and bevelling ophthalmic lenses, of the type comprising a frame structure and a support in which the lens-holding spindle is rotatably mounted, said support being connected and guided in relation to said frame structure in such a manner that, during the penetration of the tool into the lens material and operative portion of the tool remains substantially on a portion of a so-called meniscus sphere, centered to the spindle axis and located within the thickness of said lens. The support is connected to the frame via a connecting-rod of same length as the radius of said meniscus sphere, and by another pair of connecting-rods of equal length, parallel to each other and pivoted on the one hand to said frame structure, each by means of a universal joint, and on the other hand to the spindle support, each by means of a pivotal connection having its axis perpendicular to the spindle axis but not intersecting the line interconnecting the centres of said universal joints.

    Abstract: A method for machining the peripheral portion of flexible contact lenses. A flexible contact lens blank is gripped between a pair of aligned rotary spindles which are then set in rotation. The actual machining is effected by a working surface which is preferably planar and covered with an abrasive material corresponding to the type of working treatment the contact lens blank is to undergo. The working surface is brought into contact with the angular peripheral edge of the lens blank until there is deformation of the peripheral portion of the lens blank. By holding the working surface in position relative to the lens blank being worked, the faces of the blank at the periphery are automatically alternately and successively worked.

    Abstract translation: 一种加工柔性隐形眼镜周边部分的方法。 柔性隐形眼镜毛坯被夹持在一对对准的旋转心轴之间，然后将其旋转。 实际的加工是由工作表面进行的，该工作表面优选是平面的，并且覆盖着与隐形眼镜坯料要进行的工作处理类型对应的研磨材料。 工作表面与透镜毛坯的角度周边边缘接触，直到透镜毛坯的周边部分发生变形。 通过将工作表面相对于正在加工的镜片坯料保持在适当位置，周边的坯料的表面自动交替地并且连续地加工。
