Abstract

PURPOSE:To improve reproductivity and mass production without requiring much work by transferring a screen member with taking enough time along a specified range on the parallel route of a belt provided with a lens mold. CONSTITUTION:When a screen member 9, such as an acrylic resin plate in softened state adjusted by an extruder 10 is extruded and fed in the parallel route of endless stainless belts 1 and 2, the screen member 9 is caught between both belts 1 and 2 heated by heaters 8 and 8 at proper temperatures and extruded through extrusion rolls 7 and 7.... While it advances by a certain range. Fresnel and lenticular lenses are extruded and molded on both sides of the screen member 9, individually.
