ABSTRACT:
Apparatus for removing surplus at one side of an unequalized tobacco stream includes a transporting unit with a pneumatic conveyor having an endless foraminous belt which overlies the stream and defines with two sidewalls a channel for advancement of the stream along an elongated path so that the surplus extends downwardly beyond a preselected distance from the underside of the belt. The mechanism for trimming the surplus off the moving stream comprises two disc-shaped gripping members which define a nip for the entry of successive increments of the stream directly above the surplus, and a rotary knife having a circular cutting edge which separates the surplus from the major portion of the stream immediately below the nip. The knife can form part of or can be disposed immediately above a coaxial rotary deflector which directs the severed suplus in a desired direction. A driven rotary paddle wheel can be installed upstream of the nip to remove some of the surplus, and a rotary device which compacts longitudinally spaced apart portions of the stream can be installed between the paddle wheel and the nip.
