Definitions

  • tobacco tends to pour or feed more readily and suction means 'are employed, together with means 25 uniformly than irregular or long shreds which .providing a blast of air tocarry the cross-cut tend to cling together in ropes or knots. It has leaves into the nip of the shredding disks, and long been known that by picking the tobacco fresuitable means are provided for keepingthe crossquently or more severely so as tc break up the cut means clear and for stripping the same of m shreds, more uniform feeding of the cigarettes adhering leaf portions. .30
  • disk'type Shredders is thek feeding of the The present invention makes possible more unileaves in suitable condition for shredding. 'As form feeding and thus more uniform cigarettes already pointed out, irregular feeding in bunches without producing 'an excessive amount of shorts. or knots jams the disks.

To -in ing aretoo long for the best manufacture of this end pneumatic leaf feeding means are pro- 40 cigarettes.
  • Anothery object of the -present invention partendingin the direction of movement of the ticularly the crushing'feat'ure thereof is'the elimileaves through the shredding means, in order to a't'i'on of so-ca-lled match sticks, birds-eyes, y shred tobacco without compressing the same into and losses due to excessive quantity' of tobacco s; a cheese and thus rendering the tobacco less material being winnowed out in the cigarette 5r fluffy and sometimes darkening it. In this confeed.
  • one purpose of the invention is to obviate ⁇ this cigarette. lWhen a good sized stem or veined portion passes through the disks crosswise, there is produced what is often termed a birds-eye, namely a slice of the. woody stem portion.
