Definitions

  • This invention relates to tobacco products suitable for smoking, and more particularly to tobacco products formed of comminuted tobacco and a binding agent forthe tobacco particles.
  • the tensile strength obtained with a tobacco sheet made of ground tobacco containing as much as 2.8% by weight of particles coarser than 80-mesh falls far short of the tensile strengths now attainable pursuant to this invention.
  • Unexpectedly high tensile strengths are obtained when tobacco is dry ground to a powder having a screen analysis of more than 99% by weight through a 100-mesh screen and more than 86% through ZOO-mesh.
  • more than 95% by weight of the tobacco powder should pass through a ZOO-mesh screen.
  • Batch A was ground in a Gruendler pulverizer (hammertype mill with horizontal shaft)
  • batch B was first passed through the Gruendler pulverizer and then through a Mikro-Bud grinder.
  • batch C was twice ground in a Shutz-ONeill pulverizer (mill with beater plates having fixed hammers).' t
  • Each batch of ground German tobacco was converted to a tobacco sheet using the same procedure and formulation in each instance.
  • 100 weight parts of tobacco powder there were used 14.7 parts of methyl cel lulose (400 centipoise grade), 22.8 parts of triethylene glycol, 6.3 parts of diatomaceous-earth, 6.3 parts of finely powdered siliceous catalyst, and sufiicientwater to form a 2.5% by weight solution of the methyl cellulose.
  • Samples of the tobacco sheets produced from the three batches of ground German tobacco were subjected Iunder the same conditions to. tensile strength tests.
  • a tobacco powder had a tensile strength of grams per square millimeter, that of batch B 145 grams per square millimeter and that of, batch C 190 grams per square millimeter. Accordingly, by eliminating only 1.6% by weight of tobacco particles coarser than -mesh and decreasing the amount of tobacco powder coarserthan ZOO-mesh from 18.4% to 11.7% by weight, the tensile strength of the tobacco sheet was increased about 60%. In the case of batch C tobacco powder, the sheet showed an improvement in tensile strength of over 100% when compared with the sheet made of batch A tobacco powder.
  • each batch of ground cigar tobacco was converted to a tobacco sheet.
  • Each 100 weight parts of tobacco powder were combined with 14.7 parts of methyl cellulose (4000 centipoise grade), 22.8 parts of triethylene glycol, 6.3 parts of diatomaceous earth, 6.3 parts of finely powdered siliceous catalyst, and sufficient water to form a 2% by weight solution of the methyl cellulose.
  • the resulting pasty mixture was spread in a thin layer and dried to a coherent tobacco sheet.
  • the process of converting tobacco into a continuous sheet of improved tensile strength which comprises dry grinding tobacco to particles more than 99% by weight of which pass through a lOO-mesh screen and more than by weight of which pass through a 200- mesh screen, admixing said particles With an aqueous solution of a binding agent, spreading the resulting admixture of said particles and said solution as a continuous film and drying said film to yield a continuous sheet of improved tensile strength.
  • the process of of tobacco is effected in a 12.
  • the process of claim is methyl cellulose.
