  • Sheets-Sheet 5 Filed Sept. 14, 1962 INVENTOR W/A l/AM HUOfid/V GIL ES ATTORNEY Jan. 26, 1965 w. H. GILES SPLICING MACHINES 5 Sheets-Sheet 4 Filed Sept. 14, 1962 n INVENTOR.
  • This invention relates to splicing machines having a pair of supply rolls and means for splicing the web from a fresh supply roll to the trailing end of the web from an exhausted supply web.
  • the reserve web When the web from the reserve supply roll is to be spliced to the trailing end of the exhausted web the reserve web must be pulled into the splicer at a high rate of speed to match the speed of the exhausted web. This places a shock load on the reserve web and if the paper in the web does not have sufiicient tensile strength to withstand the pull, the paper will be torn.
  • An example of such paper is cigarette paper.
  • This invention has for its salient object to provide a splicing machine with supplementary or booster driving or feeding means eliminating the shock load as the splice is made by positively driving the paper supply roll from which the paper web is being withdrawn and fed through the splicing machine to a wrapping machine.
  • Another object of the invention is to provide means for controlling the tension onthe Web being fed, eliminating the need for a brake or other tension control device.
  • Another object of the invention is to provide a supply roll drive of the character described and control mechanism for automatically moving the drive for a fresh supply into operation when the paper on the alternative or other supply roll is exhausted.
  • FIG. '3 is a top plan view of the portion of the machine shown in FIG. 2;
  • FIG. 3A is -a top plan view of the portion of the machine shown in FIG. 2A, parts being omitted.
  • FIG. 4 is a sectional elevation of the central portion of the machine, showing particularly the control mechanism for the right hand paper feeding mechanism;
  • FIG. 5 is a detail elevational view, partly in section, showing the driving connections between the central or primary feed rolls and the paper feed driving mechanism atthe left of the center, this view showing the solenoid control for these driving connections;
  • FIG. 6 is a sectional elevation on an enlarged scale taken substantially on line 66 of FIG. 4, looking in the direction of the arrows;
  • FIG. 7 is an enlarged detail elevational view of the primary feed rolls showing the web's in the position taken when they are being spliced.
  • the invention briefly described, consists of a splicing machine having primary and secondary web feeding rolls,
  • each web having secondary feeding rolls so controlled that I when one of the webs is exhausted the secondary feeding rolls for the other web will be automatically set into operation to feed the fresh supply web into a position in which it is spliced to the trailing end of the exhausted supply web.
  • the splicing mechanism particularly illustrated in the drawings is mounted in a frame comprising a pair of side walls 10 and 11 supported by suitable pedestals Hand 13. a Each of the walls 10 and 11 has extending upwardly There are two sets of web feeding rolls, one for each I of the webs. The web is fed from the splicing machine by feed rolls 22 and 23 which feed the web to a wrapping.
  • the web is withdrawn from the splicing machine by the feed rolls 22 and 23 through a pair of primary feed rolls 24 and 25 which receive the web from secondary feeding rolls, one set of secondary feed rolls being provided for each of the webs. Since both sets of secondary feed rolls are exactly alike and are similarly controlled in their operation, the right handset, viewing FIG. 4, will be described and designated by reference charactersjand the left hand set, which is shown in FIG. 2, will be designated by the same reference characters primed.
  • the right hand auxiliary feeding mechanism comprises a pair of feed rolls and 31.
  • the feed roll 31 is mounted between the side frames 10 and 11 and the feed roll 30 is mounted between a pair of arms 32 and 33 which are pivoted on a stud 34.
  • the arms 32 and 33 have extending downwardly therefrom, brackets 35 and 35, in which are mounted rolls 36 and 37.
  • the web being fed passes first around an idler 40, over an idler 41 and a second idler 42, and thence between a pair of rolls 43 and 44.
  • the rolls 43 and 44 when in their normal position, as shown in FIG. 2A, receive the web therebetween, but these rolls are formed of separated sections, as shown particularly in FIG. 6, the sections on the roll 44 being designated'49.
  • the roll sections are so spaced that they can intermesh so that the sections 48 will be disposed between the sections 49 at their peripheries, as shown in FIG. 4. This takes place when the web passing through the rolls 43 and 44, which may be termed detector rolls, is exhausted.
  • the roll 44 is mounted on a bracket 50 pivoted on a spindle 51 which carries the idler roll 42.
  • the bracket 50 can swing on its pivot and is swung in a clockwise direction by a spring actuated switch blade 52 which carries a roller 53, which in turn engages the downwardly extending end 54 of the bracket 50.
