摘要： A device and method for spin casting articles such as lenses employing a polymerization tube (2) in conjunction with a plurality of molds (8) such that the tube (2) is adapted to accommodate the plurality of molds (8) in an interference fitting and sliding relationship so that rotation of the polymerization tube (2) will cause the molds (8) to rotate at the same speed while maintaining the concentricity of the molds (8) to the spinning axis of the tube (2) to produce quality spun cast articles.

摘要： An improved gas feed means adapted to accommodate and secure the lower end of a polymerization column (1) for synchronous rotation therewith and adapted to supply a controlled amount of a gaseous medium, such as nitrogen, into and through the rotating polymerization column (1) so as to purge any undesirable gas within the polymerization column (1) that could adversely affect the quality of the objects being centrifugally casted.
