PCT No. PCT/FI96/00557 Sec. 371 Date Aug. 18, 1998 Sec. 102(e) Date Aug. 18, 1998 PCT Filed Oct. 22, 1996 PCT Pub. No. WO97/15531 PCT Pub. Date May 1, 1997A heat transfer method in a glass bending furnace, which has a top array of of successive heating sections (2) and under it a bottom array of successive cooling sections (3), and in which method glass sheets are conveyed on bending molds in mold carrying wagons on the top conveyor track from one heating section (2) to the next and on the bottom conveyor track from one section (3) to the next and the air heated by the bent hot glasses is sucked from cooling section (3) and blasted to the non-bent colder glasses in the heating sections (2). In order to intensify heat transfer, air sucked from the cooling section (3) is blasted as such, against the travel direction of the mold carrying wagons through the heating sections (2) to non-bent colder glass sheets in one of the heating sections (2) preceding the heating section (2) directly above the cooling section (3) from which the heated air is drawn as viewed in a direction of travel of the mold carrying wagons through the heating sections (2).
