Patent number: 8726697Abstract: A convection heating furnace for a glass sheet, into which oven glass sheet (3) arrives along a hauling track, as on moving rolls (4), and said furnace further comprises of heating elements (12), in order to heat the air, which is blasted against glass sheet (3), a blaster and blast air channelling in order to blast said air against the glass sheet, and the blast air channelling has, elongated channels (1), into which at least a part of the blast air heating elements 12 are fitted, and each channel comprises air blasting means on its flank directed against the glass sheet (3). As air blast elements there are nozzle groups fixed on the channel (1) flank, where the nozzle group formed of sheet metal, as of two, into shape formed sheets joined together to form a casing, whereby said casing comprises one or several for blast air directed discharge channels (6), and the direction of air flow in said casing (2) is essentially in the same direction as in said discharge channels (6).Type: GrantFiled: December 13, 2007Date of Patent: May 20, 2014Assignee: Glassrobots OyInventors: Petri Lammi, Esa Lammi

Publication number: 20060123848Abstract: A method to observe glass (1) and to regulate the heating effect of heating elements (5) in a sheet glass hardening furnace, which furnace comprises a glass heating sector, a transportation rail (3) to transport glass (1) to and from the said heating section and said heating elements (5) to heat the glass by means of radiation and air blast, and a furnace control system to carry out the hardening process of glass (1). The location area in the furnace of one or several glass sheets (1), watched from the glass sheet level, is observed with measuring instruments (6), by means of which air temperatures in the heating section above glass (1) transportation rail (3) is measured and the heating effect of their heating elements (5) raised by regulation, at which the location of glass sheet (1) is observed by means of the method.Type: ApplicationFiled: June 10, 2004Publication date: June 15, 2006Inventor: Petri Lammi
