The heater box module comprises an upper heating box (1) and a lower heating box (2), where heat is delivered by an upper infrared radiator (17a, 17b) and a lower infrared radiator (27a, 27) into a glass flow zone between the heating boxes for two-sided heating of a glass package. Each of the upper heating box and the lower heating box has upper and lower heating zones. One of the infrared radiators is provided with a first heating coil (6) and a second heating coil (7). The first heating coil covers a sector that is located on an edge of the glass flow zone.

Each of the upper heating box and the lower heating box has upper and lower heating zones. One of the infrared radiators is provided with a first heating coil (6) and a second heating coil (7). The first heating coil covers a sector that is located on an edge of the glass flow zone and occupies nearly half of the width of the glass flow zone. The second heating coil covers a sector that occupies nearly the entire width of the glass flow zone. The first and second heating coils are alternatively switched.
