Document Type and Number:
Japanese Patent JP2949365
Kind Code:
B2
Abstract:
A flat glass sheet (205) to be bent into a curve is supported on an array of drivable mini-rollers (213) mounted in rows on longitudinal supports (215) in an oven (191). During heating, the rollers are oscillated about their axes and their top surfaces lies in a plane and engage the underside of the glass sheet. After heating, the supports (215) are lowered by actuators (221) through appropriate distances to achieve the required contour for the glass sheet. The mini-rollers (213) are then rotated to move the bent sheet onto correspondingly arranged rows of quenching rollers in a quenching section having upper and lower quenching tubes for blowing quenching air onto the upper and lower surfaces of the sheet. Suitable mini roller constructions are disclosed for avoiding damage to the sheets.
