    摘要： In the manufacture of an article such as optical fiber which includes a light energy cured coating material, fiber (21) is drawn from a preform (22) and coating with one or preferably two layers (42,44) of light curable coating materials. Afterwards, the coating materials are cured. Increases in manufacturing line speed may be achieved if the cure speed of the coating materials is increased. This is accomplished by the simultaneous application of a magnetic field during irradiation of the curable coating materials to enhance the crosslinking of the coating materials by a free radical polymerization mechanism. Upon absorption of light, a photoinitiator in each composition cleaves to produce two free radical fragments in the spin paired or singlet state. The magnetic field has the effect of enhancing the production of spin parallel radicals which enhances the polymerization initiation of the coating material, thereby allowing an increase in the manufacturing line speed through drawing and coating apparatus.

    摘要： Methods and apparatus are disclosed for binding of particulate materials to manufacture articles including continuous panels or sheets (22). Particulate feed materials are mixed with a heat curable binder and the mixture (21) is fed to and compressed in a die (25). A radio frequency (RF) field is applied across electrodes (28, 29) between which the mixture is held compressed to inductively or dielectrically heat and cure the binder. Prior to entering the die (25) the mixture is first fed to an intake zone (32) where the mixture is shaped into substantially the same shape as the shape of the mixture in the die so that any curing of the binder due to heating of the mixture in the intake zone (32) occurs while the mixture is in the desired final shape. Operating parameters including shape and dimensions of the intake zone, mixture advancement lengths, are disclosed.
