Abstract
A mould is described for moulding an elastomeric glazing profile in situ on a single major face of a sheet of glazing material, e.g. a glass sheet. The mould comprises a first mould segment and at least one further mould segment which are relatively movable into intimate contact, so that they define, together with the sheet, a mould cavity for moulding the profile on the single major face. The profile has a show face, (i.e. one which is visible in use), and the portion of the mould cavity that moulds the show face is entirely formed by a single mould segment to avoid mould lines on the show face. Also described are a corresponding moulding method and the glazing product thereby obtained, which may be used as a vehicle window.
Claims9
A mould for moulding an elastomeric glazing profile in situ on a sheet of glazing material having two major faces and a peripheral edge face, the profile having a show face, wherein the mould comprises a first mould segment and at least one further mould segment which are relatively movable into a position in which they are in intimate contact with each other, at least one of the mould segments being arranged to receive the sheet of glazing material, and the mould segments defining together with the sheet a mould cavity for moulding the profile on a single major face of the sheet, and wherein the portion of the mould cavity that moulds the show face is entirely formed by a single mould segment.
