Abstract (en)

[origin: WO0128777A1] Apparatus and a method for enhancing the effectiveness of a water spray (30) to cool and/or remoisten a web (12) of material. The apparatus includes a web dryer, preferably a flotation dryer (100), an electrostatic charge generating device (31) or devices, a water spray (30), an integrated power supply (20) to supply high voltage power to the charge device, and a drainage system (35) for handling excess liquid generated during the cooling and/or remoistening of the web. The cooling apparatus is capable of a modular arrangement to optimize spacing and facilitate the addition of cooling capacity where needed, such as with faster web speeds or heavier web weights. One or more temperature sensors can be used to optimize the amount of and rate of fluid fed to the spray nozzles. The spray nozzles and charge bars can be retractable with respect to the web to facilitate web-up procedures.
