METHOD AND DEVICE FOR FILLING A CAVITY BETWEEN TWO SHEETS OF FIRE-RESISTING COMPOSITE GLASS

摘要

A fire-resisting composite glass is comprised of at least two glass plates ( 1, 2 ) and an interspaced cavity ( 6 ). The distance between the glass plates ( 1, 2 ) is determined by an encompassing bead ( 3 ) of plastic spacer material. In addition, in the margin region between the glass plates ( 1, 2 ) a bead ( 4 ) of sealing material is introduced. With the aid of at least one core element an opening is formed in the bead ( 3 ) of spacer material for filling the cavity ( 6 ). After the filling, this opening is closed with an entrainer stopper and simultaneously the cavity ( 6 ) is vented. During the closing the plastic spacer material ( 3 ) is joined again in the region of the opening and subsequently the entrainer stopper is covered with sealing material ( 4 ). The method and the device for carrying out the method permits the automatic application of encompassing beads ( 3, 4 ) of spacer material or of sealing material as well as the sealing and protection of the margin regions before the cavity ( 6 ) is filled.
