The invention provides a technique and a device for dry formation of low basis weight fluff pulp and capable of eliminating electrostatic flocculation. The technique for dry formation of low basis weight fluff pulp and elimination of electrostatic flocculation within a quantitative range of from 15g/m2 to 30g/m2, a high-mesh-number woven copper net serving as a formation net is used with an electrostatic elimination device to produce a fluff pulp fiber underlayer of reconstructed tobacco, uniform formation is facilitated, electrostatic elimination is facilitated, and transfer and removal of the formed underlayer fibers from the formation net are facilitated. The technique and the device are characterized in that the formation net is a woven endless net of metal wires, zero potential nets are square-hole static-eliminated nets respectively and horizontally disposed at the top and the bottom of a cylindrical screen, and a frame grounding system is an independent equipotential system using a frame as zero potential.
