摘要

Nozzle bank for the suspended guidance of product webs comprises several nozzle caps (4-6) provided with hole-type (12) and slot nozzles (13-15) through which gases are guided to heat/cool the product webs. The total nozzle surface area formed by the hole-type and slot nozzles is the same for all or individual nozzle caps of the nozzle bank measured in the transport direction irrespective of the distance to the lateral edges (10) of the respective nozzle cap running parallel to the transport direction. The proportion of the total surface area formed by the slot nozzles directed toward the lateral edges of the respective nozzle cap running parallel to the direction of transport is increased in relation to the proportion of the nozzles situated in the center of the product web.
