초록 ▼

The starting end and the finishing end of a seam extruded onto a sheet of glass, for example a windshield of an automobile, are joined to complete an edge gasket. A separate supplementary mold receives part of the glass containing the ends of the seam, and a compatible polymerizable composition is p

대표청구항 ▼

A method of forming a gasket along an edge of a sheet of glass, said method comprising: extruding a seam along only a portion of the edge of the sheet of glass by delivering a polymeric material under pressure from a nozzle of an extrusion device, calibrated to impart to the seam a cross-sectional shape including a first portion contacting the sheet of glass and a second portion projecting outwardly from the first portion to a position above a plane in which the sheet of glass lies, by moving the nozzle along the edge of the glass at a predetermined speed, and by terminating the delivery of plastic material once the nozzle is adjacent a first-formed head end of the seam so as to leave a second-formed tail end of the seam opposing and spaced from the head end; allowing the seam to polymerize in situ; orienting the sheet of glass in a vertical or nearly vertical position with the opposed ends of the seam located at a lowermost position; positioning the sheet of glass in a mold, including a body of elastic plastic material configured to accommodate a portion of the sheet of glass at which the ends of the seam are located and having a cavity therein of a cross-sectional shape corresponding to that of said seam, with said portion of the sheet so accommodated in the body of elastic plastic material, the mold being movable between an open position at which the cavity is exposed and a closed position at which the cavity extends between the ends of the seam when said portion of the sheet of glass is accommodated in the body of elastic material; while the mold is in the open position thereof and the sheet is oriented in the vertical or nearly vertical position, pouring a polymerizable polyurethane composition compatible with material of the seam into the mold in an amount sufficient to fill the cavity with the composition; moving the mold to the closed position thereof after the polyurethane composition has been poured into the mold whereupon the polyurethane composition in the cavity assumes a shape corresponding to that of the seam; polymerizing the polyurethane composition disposed in the cavity; moving the mold to the open position thereof after the composition has been polymerized; and subsequently extracting the sheet of glass from the mold.
