  • This IIIVQIIEIOII relates to paper-folding inachines', and has for its OlJJOQt an improved machine adapted to 'fold a number of long ribl bons of paper, givingto each ribbon a s ngle fold alongitslongitudinal middle line, and so arranging the consecutively tolded ribbons that each ribbon except the two outside ones embraces between itsadjaecnt faces the edges .oftwo adjacent ribbons of paper, one of which lies partly within and partly without on the one side and the other of which liespartly within and partly without on the other side. If thefold or? crease of each ribbon be considered a midrib and the portions of the ribbons of paper. at eacli side of the midrib be considered wings, then the consecutive ribbons of paper will take a positionsuch that if the first ribbon have the midrib upward and-the wi-ngs'turned downward the second ,a-"f wings turned upward.
  • the machine which is shown in the drawings is adapted to crease and :fold twelve ribi bons at a time, sixof which are creased at the right end of the machine and six of which are creased at the left cngl of the machine, and the 5 5 two bundles of ribbo'ns'are engagedtogether,
  • the short bun- 7 dles of paper are placed in a box which is covered, .”and. the cover of which is provided with a central slit-that runs parallel to the i'olded edges otthe sheets of paper that are in the box.
  • the end of one sheet of paper is pulled 7 5 throughthe slit, and when it is pulled farther through theslit and out of the box it draws with it the end of a second fsheet of paper, which is left projecting through the slit in the box.
  • the paper prepared and-presented in 3 this Way can be drawn a sheet ata time from the box, but no faster.
  • Figure v1 is a perspective of the machine.
  • Fig. 2 is a diagram indicating the position assurncdby the ribbonsof' 5 paper when partially folded.
  • Fig. 3 is a dctail of, a drawing-die by which the paper is folded.
  • Fig. 4 is a detail ofa head-block over which the ribbons are drawn.
  • Fig. 5 indicates the position of the two parts of the foldingm'achine assembled at the ends of a table on which the'bundles of paper are gathered.
  • the right and left endsof the rnachine are alike, and the two partsare united by-a trough in which the bundles of ribbons drawn from the right-end of the machine and those drawn from the left end of the machine are assembled and gathered during the progress of the work of'making the large .bundle mentioned.
  • dies are similarin construction, and each'consists of. an under die-block, (shown in det 'il in Fig. 3,) and the underdie-blOckhaS a numher-of serrations or teeth that rise above its surface.
  • Hinged to the under block 4 is an upper block 3, which is 'also' serrated, and the serrations of-the lower block 4 engage in the notches. between the serrations of the upper block 3, andthe serrations ofthe upper block 3 engage in the notches of the lower block 4;.
  • the block?) is' hcld to block 4 by hinge 5 and by book 6, and
  • I has serrations of narrow bases and deep notches, the intermediatedrawing-dies having serrations of. which the bases are narrower than the first and :less'narrow thanjthe lastf and the notches deeper than the'first and less deep than the last die- C, and each reel is provided with ajournal i that'is supported inbear'ings D' D. atthe end of the table I
  • the head blocks bringthe ribbons of'paper to the same or nearly the same'pla'ne and produce on each ribbon an.
  • Thebundle'of ribbon draw'nfrom Y the right end: of t he machine is laid in'the trough J and pressed against thev side jof the trough; but the outerfnost ribbon on the free bon of the bundle drawh-froriith left of the machine-is laidin the'open'angle'of thejla'st side is opened outipa'rtiallyfand the first ribribbon of the; first 'bundle drawmand thetwo' bundles whenpressed up against theside of I the trough become a single bundle; The'outermost ribbon of the compound bundle is again arranged to-engagetwith the innerrib bgn of'a bundle drawn from thejright of the "70' machine.
  • aribbOn-bundlin'g machine means for -,lo'n'gi-tudinal-l y advancing and transversely" bending a plurality of ribbons, and, means for I O5,
  • a plurality of convergent folders adapted to form lonto simultaneously and progressively interfold gitudinal creases in a plurality of ribbons and the ribbons to form aweb in which each interjacent ribbon I I I is interfolded with ribbons on bothsidesj 13.
  • a machine foriinterfolding a pl umiity of strips or ribbons comprising a plurality of folding. devices arranged on convergent lines and adapted to independently and progress- :ively fold the-strips: or ribbons and to simultaneously. inter'fold the progressively-folding.- stripswith each other.
  • a folding-machine comprising a plural I ity of folding devices arranged on convergent lines and each adapted for independent enindependent strips comprising a plurality of converging members adapted to fold alternate strips in opposite directions, the construction being such that the independentstrips are progressively interfolded to form a compact web at the discharge end of the machine' 16.
  • a folding mechanism a-t each endof said table provided with serrated folding-dies, whereby ribbons of paper folded lengthwise may be drawn from each -foldingmechanism, and the ribbon from one mechanism" engaged with the ribbon from the opposite mechanism, substantially as described.
