Rod forming apparatus
An apparatus for the formation of machine-made tobacco rods for use in the production of smoking articles, such as cigars, from tobacco comprising a tacky material. The apparatus includes a pair of transfer and compression belts for receiving and compressing the stream of tobacco, the transfer and compression; a pair of squeeze bars for compressing the tobacco in a direction perpendicular to the pair of transfer and compression belts, the pair of squeeze bars produced from a material comprising a poly(aryl ether ketone); a tongue for receiving the compressed tobacco, the tongue produced from a material comprising a poly(aryl ether ketone); and a folder for folding a wrapper material around the compressed tobacco so as to form a continuous rod of tobacco, the wrapper material provided from a source of wrapper material, the folder produced from a material comprising a poly(aryl ether ketone).
1. In the formation of machine-made tobacco rods from a tobacco comprising a tacky material, a method of decreasing tobacco waste, comprising the steps of:
providing a plurality of components of a tobacco rod-making machine, the plurality of components including a pair of squeeze bars, the plurality of components produced from a material comprising a poly(aryl ether ketone); and
reducing at least one gap by at least 20% between the pair of squeeze bars with an adjacent component of the tobacco rod-making machine to reduce an amount of tobacco escaping through the gap compared to a gap between components free of poly(aryl ether ketone).
2. The method of claim 1 , further comprising:
producing tobacco rods by operating the tobacco rod-making machine, wherein tobacco waste in the producing is decreased after the reducing.
3. The method of claim 2 , wherein tobacco waste in the operating is decreased by at least 25%.
4. The method of claim 3 , wherein tobacco waste in the operating is decreased by at least 50%.
5. The method of claim 4 , wherein tobacco waste in the operating is decreased by at least 80%.
6. The method of claim 1 , wherein the poly(aryl ether ketone) is polyether ether ketone (PEEK).
7. The method of claim 1 , wherein the reducing includes reducing the at least one gap by at least 30%.
8. The method of claim 7 , wherein the reducing includes reducing the at least one gap by at least 40%.
9. The method of claim 1 , wherein the reducing includes reducing the at least one gap from a first gap to a second gap, the second gap being 20% of the first gap.
10. The method of claim 1 , wherein the at least one gap is about 0.02 inches after the reducing.
