Abstract
The invention relates to the manufacture of laminated glass, comprising glass sheets and plastic sheets. In the manufacture, glass and plastic sheets are each cut to a final dimension desired for use in laminated glass, assembled in a preliminary way, and, then, by the action of temperature and pressure formed to the laminate. The cutting of the plastic sheets, is carried out more particularly a plastic sheet of polyvinyl butyral as an interlayer between outer sheets of silicate glass is carried out by a high pressure water jet.
Claims6
A process for manufacturing a laminate of glass and plastic sheets, which comprises:
- providing a glass sheet having predetermined dimensions;
- accurately and precisely cutting a polyvinyl butyral sheet to predetermined final dimensions by high pressure water jet means, the predetermined final dimensions of said polyvinyl butyral sheet being no greater than the predetermined dimensions of said glass sheet;
- stacking said glass and polyvinyl butyral sheets in contact relation and in alignment for formation of the laminate;
- subjecting said stacked sheets to the action of elevated temperature and pressure so as to form a laminate, whereby the polyvinyl butyral sheet does not extend beyond a peripheral dimension of the glass sheet, thus avoiding trimming and further cutting of said polyvinyl butyral sheet;
- and further whereby the adherence of said polyvinyl butyral sheet to said glass sheet is unaffected and the optical properties of said polyvinyl butyral sheet remain unaffected for clear viewing through the laminate.
