Abstract

Sheets are placed horizontally and heated to prestressing temp. if necessary after bonding, and forwarded to a shrinkage zone contg. a pref. gaseous coolant directed on to both sides of the sheet. In the entry region of the zone a connected stream of coolant is directed at an acute angle on to both sides. Pref. the angle is 45 degrees. Apparatus is described.
