ABSTRACT:
An apparatus (10) for registering a glass sheet (12) on a mold (24) is disclosed as including a plurality of glass sheet locators (26) movably mounted on the mold. Each locator (26) includes a connector (28) pivotal in a horizontal plane about a pivotal axis (A) extending vertically from the mold. Each connector (28) also is vertically moveable along its pivotal axis (A) between a raised position above the mold (24) for locating the glass sheet (12) as the glass sheet moves along a topside transfer platen (14) and a lowered position below a curved mold surface (25). Linkages (30) connect the locators (26) for cooperable operation to position the glass sheet (12) with respect to the mold (24). An actuator (32) moves the linkages (30) to raise the locators (26) above the mold to locate the glass sheet (12) on the topside transfer platen (14) with the cooperable operation of a back gate (22). The actuator (32) also operates pivotal movement of the connectors (28) to position the glass sheet (12) for subsequent registration with the curved mold surface (25).
