Abstract
A fluidized mixture is issued from a nozzle comprising a fan jet at the outlet, causing the mixture to spread as it is issued. The issued material is collected on a moving collection surface located a distance of between 0.25 and 13 cm from the outlet of the nozzle, prior to the onset of large scale turbulence in the fluid jet. The resulting product has good basis weight uniformity.
