    Abstract: Curved lenses and methods for making curved lenses are described. One embodiment of a method of making a curved lens includes curving a lens blank made of a linear polarizer layer laminated together with a plurality of polymeric layers. The lens blank is curved by engendering rotational motion about a rotational axis of a roller having a forming surface thereon and lateral motion of a belt in contact with the forming surface. The lens blank is heated and pressed between the belt and the forming surface at a pressure, the pressure being supplied by tension on the belt. The pressure is maintained for a time sufficient to allow the lens blank to conform to the shape of the forming surface. Methods of the invention may be used to make curved lenses with different polarization properties and curvatures.

    Abstract: An apparatus for thermoforming a thermoplastic article comprises an extrusion die for extruding a sheet of thermoplastic and a rotating wheel having at least one mold member. The mold member includes a male mold or forming cavity for receiving at least a portion of a substantially non-oriented (i.e., non-tensioned) thermoplastic sheet. The mold member is selectively heated and/or cooled during thermoforming to maintain the sheet in a molten or thermoformable state. The mold member also comprises a stripper plate maintained at a predetermined temperature or temperature distribution for inducing a predetermined degree of crystallinity to the sheet. The stripper plate enables the articles to be separated from the mold without distortion. In one embodiment, the thermoformed article has at least two and preferably at least three distinct regions of thermally-induced crystallinity.

    Abstract: A machine and method of forming multi-compartment pouches is disclosed in which two pouches formed on separate adjacent formers (1, 3) are brought together in register and the lidding webs (9, 15) of the pouches joined to form a combined pouch (33). The pouches may be held on the formers (1, 3) by vacuum until the pouches are joined whereupon the vacuum holding one of the pouches on its former (1) is released while maintaining the vacuum holding the other pouch on its former (3) so that the combined pouches (33) are held on that former by the vacuum until the vacuum is released.
