FORFARANDE OCH APPARAT FOR BOJNING AV GLASSKIVOR |
摘要 |
A method and apparatus are described for bending sheets in the plastic state, such as sheets of glass at their softening temperature, in two directions. The apparatus comprises a first bed of arcuate rods which can be positioned to impart a transverse curvature to the sheet and a second bed of arcuate rods which can be positioned to impart a longitudinal curvature to the sheet. Advantageously the bending is performed in a heated enclosure at a temperature at least equal to that at which the sheet is later tempered. |
