Abstract
The invention relates to an air-exhausting lehr for laminated glass sheets, including a tunnel-like lehr, a conveyor, including elements for carrying laminated glass sheets in a substantially upright position through the lehr, and air circulation ducts, having fans and heating elements associated therewith for blasting heated air between the laminated glass sheets presently on the conveyor within the lehr. The lehr has its sides provided with movable walls for adjusting the lehr width to match a given glass size. This results in an enhanced passage of air between glass sheets regardless of variations in glass size.
