Patent ID: 8899885

Claim:
A method for handling material in a pneumatic materials handling system, comprising: a rotary shaper device ( 1 ), the rotary shaper device ( 1 ) including: an input aperture ( 6 ), two rotatable, ring-shaped handling means ( 10 A, 10 C), one stationary ring-shaped handling means ( 10 B), and at least one replacement air coupling ( 80 , 90 ) connected to the rotary shaper device ( 1 ), wherein each of the handling means ( 10 A, 10 B, 10 C) includes: an aperture ( 11 A, 11 B, 11 C) arranged eccentrically with respect to an axis of rotation of the corresponding rotatable handling means ( 10 A, 10 C), the method comprising: receiving the material in the input aperture ( 6 ), conducting replacement air into connection with the rotary shaper device ( 1 ), rotating each of the two rotatable, ring-shaped handling means ( 10 A, 10 C), and conducting the material into and through the apertures ( 11 A, 11 B, 11 C), at least partly by gravity, or by suction, or by a pressure difference, or at least partly by a combination of two or more of the gravity, the suction, and the pressure difference.
