Various embodiments for producing a tobacco rod with a hollow cylindrical tube extending therethrough

Abstract

A method for making cigarettes comprising feeding tubing piece-by-piece to a vertical duct by opening and closing-timing gate operated by cam, accelerating tubing down to the vertical duct, with the help of vertical accelerator belts until the tubing becomes captured into the hopper holder, picking the tubing with an articulate tubing holder located on a transferring drum, lowering to the garniture, and releasing the tubing under the registration lagged-belt.

1 . A method form making cigarettes comprising:
 configuring wheels of a conveyor to allow tow porous belts to run in parallel to one another;   adding a rear rail, front rail and center divider rail to the conveyor to form a separate tobacco column on each porous belt;   feeding tobacco to an updraft chambers located below the porous belts while the belts are moving;   building-up tobacco columns on each of the porous belts;   trimming the tobacco columns with rotating trimmer disks and producing accurate tobacco weight;   moving the trimmed tobacco columns along the porous belts until the tobacco columns reach drive wheels;   feeding paper under the tobacco columns at the drive wheels and removing excess tobacco from the porous belt with a scrapper;   depositing the tobacco on moving paper and around a hollow cylindrical tube;   flowing the tobacco, tube and paper into a garniture;   forming the tobacco tube and paper into a cylindrical shape;   feeding the cylindrical shaped rod through folders and past a glue applicator that seals the paper; and   producing a finished tobacco rod for cutting into individual tobacco rods.   
   
   
       2 . A method for making cigarettes comprising:
 cutting tubing to a certain length and loading the tubing into a hopper;   picking-up the tubing with a vacuum drum and moving the tubing down vertical ducts by friction belts;   propelling pieces of the tubing with a propulsion wheel that transports the tubing;   separating the tubing with a friction spacing wheel;   registering the tubing with a lugged belt; and   entering the tubing into a garniture and tongue area.   
   
   
       3 . A method for making cigarettes comprising:
 feeding tubing piece-by-piece to a vertical duct by opening and closing-timing gate operated by cam;   accelerating tubing down to the vertical duct, with the help of vertical accelerator belts until the tubing becomes captured into the hopper holder;   picking the tubing with an articulate tubing holder located on a transferring drum, lowering to the garniture; and   releasing the tubing under the registration lagged-belt.   
   
   
       4 . A method for making cigarettes comprising:
 feeding tubing piece-by-piece to a vertical duct by opening and closing timing gate operated by cam;   accelerating tubing down to the vertical accelerator belts until it comes to rest on tubing position supports or slanted toward the garniture;   accelerating tubing horizontally in direction of tobacco flow with horizontal acceleration pusher; and   capturing the tubing by registration lagged belt.   
   
   
       5 . A method for making cigarettes comprising:
 getting tubing picked from mass flow hopper by vacuum drum;   transferring tubing to a locating drum with vacuum or mechanical retention mechanism;   turning the tubing holder of the locating drum at least 90 degree in the horizontal plan and at least 180 degrees in vertical plane; and   depositing a plug under the registration lagged belt inside of the garniture.
