The RollJet perforated roll headbox achieves a good quality stock jet by generating turbulence. Along with good profiles and flatness characteristics, high productivity can therefore be achieved.
The nozzle perforated roll of RollJet decisively determines the turbulence range required for a soft cloudy formation by means of open surface, hole diameter, hole pattern, speed and nozzle length. The tight shape adaptation of the headbox wall to the perforated roll minimizes the feared circulation around the perforated roll. The distribution quality is thus substantially improved. Shape-adjustable EdgeMaster format controls prevent bothersome wavy edges and provide for a good suspension edge. In addition, the optimized flow guide ensures high runnability through low susceptibility to contamination.
RollJet is especially suitable for specialty paper with spinning-sensitive paper stock, high ash content in the paper and with frequent grade changes.
