METHOD FOR FINISHING A SEAL EXTRUDED IN SITU ON A SHEET

摘要

Postforming of the transition area between the starting portion and the end portion of a closed-frame member extruded onto a glass sheet (1) may be achieved by means of a mould (14) that is pivotable about an axis parallel to the longitudinal axis of the extruded member, and adjacent to the surface of the glass sheet (1). The pivot axis of the mould (14) coincides with the cutting edge (15) of a lip (16) defining the edge of the calibrated cavity of the mould (14) on the inner surface of the extruded member. When the mould (14) is pivoted, excess polymeric material is pushed back towards the edge of the glass sheet and therebeyond.
