Summary: | The present invention provides a shaping mold (26,28) for shaping heat softenable sheet material (G) which includes a flexible rail (38) having a sheet shaping surface (44) to support a marginal edge portion (46) of a sheet (G) to be shaped and a plurality of controllable actuators (42) secured to the rail (38) and capable of deforming the rail (38) to provide its surface (44) with configurations each having a desired elevational contour. In one particular embodiment of the invention, the shaping rail (38) is a shaping ring having a peripheral configuration which provides generally continuous support about the marginal edge portion (46) of said sheet (G). A controller (64) is used to control each actuator (42) and deform the sheet shaping surface (44) of the ring (38) from a first configuration having a generally flat elevational contour to a second configuration having an elevational contour that generally corresponds to the final desired contour of the marginal edge portion (46) of the sheet (G). |
