Methods and apparatus for handling chewing I believe I am the first to place gum dough in a mixing or kneading machine and to cause a strand of gum to be passed continuously from the mixing machine through a nozzle, with an electric heating element about the nozzle to heat the nozzle and thereby cause a free and easy passage of the gum through the nozzle, after which the strand of gum is passed through a sugaring device where the gum; is coated with sugar on an agitated platform and at the same time moved longitudinally forward to a platform upon which the strand assumes a snake or serpentine formaion.
- The strand is then moved'forward to re-shaping rollers adjacent a wrapping machine and from the re-shaping rollers to the wrapping ma.- chine properwhere the strand is cut into individual pieces.

In carrying out my invention I place chewing o gum'dough in a mixing and conditioning machine 28 from which the gum, after proper conditioning, is extruded in a circular strand 2|. The strand passes longitudinally towards and is moved progressively forward in a sugar agitator 22 from which the strand discharges in a serpentine or snake formation 23 resting upon a tilted platform 24, desirably assuming a right angle position in plan view, with respect to the mixing and sugaring devices.
The strand then passes progressively through re-shaping rollers 25 from which it is moved while still warm, to a cutting device 26 where the strand is cut into individual pieces which are wrapped, the wrap ends being finally twisted in a wrapping machine similar to that shown in British Patent No. 293,907.
I prefer to employ a mixing and extruding machine of the type shown at 28,. having a hopper 21 into which a mass of cooked gum dough is placed for proper conditioning. The strand extruded by the mixing machine is thoroughly heated, as by the nozzle 56.
After the strand of gum 2| has passed out through a heated nozzle die 56 of the mixing machine, the strand will curve downwardly some distance to assume a position in the sugaring agitator 22 similar to that shown in Figure 5 in which the agitator 22 is shown in considerable detail.
The strand 2| as extruded from the mixing machine extends downwardly at I2 and upwardly at 13, at which .point the strand rests upon the forward curved end ll of a curved conveyor platform 15, slotted at 16. The forward end of the platform 15 is apertured at TI for the reception of a cam 18 secured to and actuated by a shaft 18 which extends transversely to the conveyor platform 15 to a position outside the casing 88 of the agitator 22, where a pulley 8| is secured to the shaft 19. The pulley 8| is driven by a belt motor 85 mounted upon a platform 86 adjacent the agitator;
At the rear end of the agitator 22 the platform- 40 82 from a pulley 83 on a shaft 84 connected to a the platform, with a space 94 between the bottom 93 and the platform. At the rear of the agitator interior, a resilient pad 95 is inserted between the agitator container and an end plate 96, to which container the pad 95 is preferably fastened.
The agitator is provided with a front wall 91 which prevents the escape of sugar from the interior of the agitator.
Towards the front end and inside of the agitator and along the side walls 98 I place resilient pads 99 which extend vertically from the bottom of the agitator to the top thereof. These.pads are preferably fastened to the side walls of the agitator. laterally due to the spring suspension of the platform, the pads will act as a buffer tohold the platform in a longitudinal position. The pads are preferably made of felt.
Other resilient pads I00 are positioned adjacent the stop 91 to aid in keeping the platform longitudinally in line. I
A brush IN is fastened in a support I02 and is attached to the agitator side walls with the bristles of the brush extending outwardly to engage the strand of chewing gum as it is passed through the sugaring machine.
The platform is shown in the form of a trough with sides I03 which help to guide the strand as it travels through the sugaring machine.
Sugar is placed in the agitator interior to rest on the bottom I04 of the agitator below and above the platform I5.
The platform is agitated by the action of the cam 18 on the cam shaft 19 through the pulleys and belt, which are motor driven. As the cam turns it will move the platform up and down, at the same time the cam will tend to -move the strand forwardly. The movement forward will be aided somewhat by the pushing forward of the strand when the um is extruded from the mixer. The movement of the platform either up and down or forwardly agitates the sugar I05 in the container to cause the sugar to form in effect a cloud, which will dust about the strand on the platform and through the slots in the platform, tocause the particles of sugar to adhere to the gum strand which is susceptible to adhesion of such particles as the gum is still warm from its heating'for the extrusion operation.
The brush IOI removes the surplus sugar from the strand as the strand is passed from the agitator onto the platform 24. The platform 24 has upwardly turned edges 24" surrounding the entire platform excepting at the entrance I06 and the exit I01, thereby preventing the strand from falling off the platform.
After the strand has moved from the agitator onto the platform it assumes a snake or serpentine formation thereon and this snake formation allows for differences in timing of the different devices used in my invention and accommodates for the travel of the strand as it is passed from one device to another. The curving of the strand also allows for its cooling sufiiciently for re-shaping, cutting and wrapping as hereinafter described. On leaving the platform 24, the strand passes between guides 242 at the exit of the platform.
The strand now passes through laterally adjustable guide members I08, then through a set of horizontal rollers I09, through'vertically disposed sets of rollers I I0, and on through other sets of horizontal rollers III and I I2. The horizontal rollers I09, III and H2 and the vertical rollers H0 are spaced along a table H3 which If the platform should tend to move supports the strand from one set of rollers to the next, until the strand reaches the knife 26. The motor-driven sprocket H4 drives the sprocket H5 by the chain H5. The driven sprocket H5 is on the shaft H6, which carries a bevel gear H1, engaging a bevel gear H8 on the same shaft as one of the vertical rollers I I0. The other vertical roller H0 is driven by the gears H9 and I20 connecting the vertical rollers II 0. On the shaft H6 a second sprocket I2I drives one of the horizontal rollers I09 by a chain I22 connecting to a sprocket I23 on the same shaft as one of the horizontal rollers I 09. The horizontal rollers I09 are interconnected by gears I24 and I25. To adjust the size of the strand, the sets of rollers I09, H0, III and H2 are changed. The guide members I08 may be adjusted by loosening the screws I26.
After the strand is cut by the rotating knife 26, the individual pieces are moved forwardly by a pusher I21 to come in contact with a continuous strip supply of paper I 28 from over a roll I29 hung from springs I29 positioned in front of a slot 130 in a recessed drum I3I on a drum shaft I32 which is controlled by a Geneva wheel (not shown).
After the individual piece of gum is brought to a position within the paper I26 in one of the recesses of the drum, a pair of scissors I33 are operated to cut an individual wrap of paper I from the paper strip.
The drum is rotated to cause the gum that has been partially covered with an individual wrap to be moved to a position 180 away from the point of insertion within the drum where twisters I35 engage the ends of the wrap to twist in and allowed to escape from the platform and a dust of sugar is formed about the strand.
