The heater box module comprises an upper heater box (1), and transport rollers in a lower heater box (2) for conveying a glass package from which heat is delivered by an upper infrared radiator (17a, 17b, 17c) and a hot air is delivered by an upper air circulation system (11, 12, 19) in an upper heating zone for heating the glass package promoted by a glass flow zone. The upper air circulation system comprises: an upper nozzle holder, where the hot air is directly blown onto an upper side of the glass package; and an upper exhaust unit for returning the hot air. The heater box module comprises an upper heater box (1), and transport rollers in a lower heater box (2) for conveying a glass package from which heat is delivered by an upper infrared radiator (17a, 17b, 17c) and a hot air is delivered by an upper air circulation system (11, 12, 19) in an upper heating zone for heating the glass package promoted by a glass flow zone. The upper air circulation system comprises: an upper nozzle holder, where the hot air is directly blown onto an upper side of the glass package; and an upper exhaust unit for returning the hot air directly from the upper side of the glass package into the upper air circulation system. The upper nozzle holder between the upper infrared radiator disposed on an upper hot air supply duct (13, 14, 15) comprises a slot nozzle directed on the upper side of the glass package. The upper hot air supply duct with the slot nozzles: parallely lies adjacent to each other; is arranged over the upper side of the glass package distributed into the upper heating zone; and extends itself over the entire width of the upper heating zone. The upper exhaust unit of the upper air circulation system comprises upper suction slots, which are directly arranged above the upper infrared radiator. A distance of the upper air circulation system and the upper infrared radiator is adjustable to the upper side of the glass package by a unit to a height adjustment of the upper heater box. A flow velocity of the hot air is adjustable into the upper air circulation system and a lower air circulation system so that a predetermined value assumes over the upper and a lower nozzle holder on the upper side of the glass package directed on a volume flow of the hot air. A lower hot air supply duct is arranged below the transport roller and comprises a pair of slot nozzles, which are laterally directed on both sides of the overlying transport roller towards the top of an underside of the glass package. A lower exhaust unit of the lower air circulation system comprises lower suction slots, which are directly arranged below a lower infrared radiator. |
