1. An apparatus for manufacturing cut reconstituted tobacco, the apparatus comprising:
a feed roller configured to supply an initial reconstituted tobacco sheet to a conveyor unit;
a flavoring apparatus configured to supply a flavoring solution onto the initial reconstituted tobacco sheet;
a primary cutter configured to manufacture a plurality of intermediate reconstituted tobacco sheets by cutting through the initial reconstituted tobacco sheet supplied with the flavoring solution using the flavoring apparatus in a longitudinal direction;
a plurality of secondary cutters arranged downstream of the primary cutter, spaced apart from one another by a certain distance, and configured to manufacture a plurality of reconstituted tobacco strands by cutting through the plurality of intermediate reconstituted tobacco sheets in the longitudinal direction; and
a plurality of tertiary cutters arranged downstream of each of the plurality of secondary cutters and configured to manufacture a plurality of pieces of cut reconstituted tobacco by cutting through the plurality of reconstituted tobacco strands in a transverse direction.
