MULTI-LAYER WINDOW GLASS WITH THROUGH HOLE WITH BEVELED EDGES Russian patent published in 2021 - IPC B32B17/10 

FIELD: window glazing.

SUBSTANCE: invention relates to the field of manufacturing multilayer glazing and relates to a method for producing a multilayer window glass with a through hole with beveled edges. The method includes the stages at which: a) preparing a first glass sheet with at least one beveled hole, which is chamfered on both sides of the glass sheet, a second glass sheet with at least one beveled hole, which has chamfers on both sides of the glass sheet, and at least one polymeric intermediate layer with at least one hole, b) positioning at least one polymeric intermediate layer between the first glass sheet and the second glass sheet, wherein at least one hole with beveled edges of the first sheet of glass, at least one hole with beveled edges of the second sheet of glass and the hole of at least one polymer intermediate layer are positioned so that at least one through hole; and c) bonding the first glass sheet to the second glass sheet by laminating with at least one polymeric intermediate layer.

EFFECT: invention provides a method for the production of laminated window glass, in which the percentage of broken glass is significantly reduced compared to the production of laminated window glass with conventional through holes without chamfers.
