Japanese Patent JPH0525469
Kind Code:
B2
Abstract:
Apparatus for feeding tobacco pneumatically into a cigarette making machine comprises a duct (10) defined on one side by a wall (10B) whose width (i.e. in cross-section) increases along the length of the duct from an inlet end (10A) to an outlet end (10B), is concave in longitudinal section so that centrifugal force on the tobacco will urge the tobacco against that wall of the duct, and carries a splitter member (14) arranged to split the tobacco stream (12) flowing along the said wall into separate streams (12A, 12B) passing along opposite sides of the splitter member, and to spread apart the two streams. From the outlet end of the duct, the air and tobacco pass into an air separator (22) from which the tobacco passes via a rotary seal (70) into the hopper of a cigarette making machine. The rotary seal may have special provision for preventing tobacco being trapped and crushed between the rotary part and the surrounding housing of the seal.
