Process and apparatus for providing a shaped polymer frame on a glass plate

A process for producing a shaped polymer frame on a plate having top and bottom main surfaces and a peripheral edge, which process comprises:

• placing adjacent the plate an extrusion die having a body which defines a plate-receiving recess for receiving the edge of the plate and portions of the main surfaces adjacent thereto;
• and a first sealing ledge which is movable between (1) a retracted position which allows entry of the plate edge into the recess, and (2) an engaged position in contact with one of the main surfaces of the plate, wherein an open area is defined between the die body, sealing ledge and the plate in the shape of the polymer frame;
• receiving the plate edge in the recess of the extrusion die;
• moving the first sealing ledge into contact relation with at least one of the main surfaces of the plate;
• and
• depositing polymer onto the plate edge and a portion of at least one of the adjacent main surfaces through the open area of the die during relative movement of the die and plate to provide the polymer frame.
