ARTHUR BARON AND JOHN THOMAS BIB KY, OF BURNLEY, ENGLAND.
MACHINE FOR MAKING THREE-CORNERED BAGS.
SPECIFICATION forming part of Letters Patent No. 460,907, dated October 6, 1891. Application filed December 18, 1890. Serial No. 375,158. (No model.) Patented in England December 10,1888, No. 17,992.
To aZZ whom it may concern:
Be it known that we, ARTHUR BARON and JOHN THOMAS BIBBY, subjects of the Queen of Great Britain, residing at Burnley, in the county of Lancaster, England, have invented new and useful Improvements in Machines for Making 'lhree-Cornered or Triangular- Shaped Bags, (for which we have received Letters Patent in England, No. 17,992, datedand folding mechanism of such bags may per-..
form their respective functions uninterruptedly while the paper is in motion. For this purpose several sets of rolls are mounted in suitable bearings on a horizontal table on-the upper part of the machine. The paper on enterin g the machine is first creased at the edge, so as to form a narrow fold longitudinally in the direction of its length. or crease .at intervals a supply of paste is deposited for the better securing of the tip or bottom of the bag. The paper thus creased and folded now passes over a disk partially immersed in'a size-trough and receives upon the outer surface of the fold a streak or supply of paste, when it is then passed forward to the first pair of rolls, which may be termed the feed-rolls, whence it passes between the next set or cutting-rolls to the third set or draw-rolls. The severance of the paper into lengths from the continuous roll of paper is effected by the cutting or severing rolls. One revolution of the said rolls severs a blank or sheet of paper. By increasing the speed of the cutting or severing rolls shorter blanks are severed, and longer blanks by reducing the speed. The traverse of the paper through the machine in both cases maybe at the same continuous speed. The speed of the cuttingrolls is determined by change-wheels and eccentric or elliptical blocks or disks. Immediately the severed sheet or blank of paper emerges from and clears the draw-rolls. Itis then creased by a knife or folding edge diag- Within this foldf onally from corner to corner through a diagonally-disposed slit extending across the table, when it is seized by a pair of rolls situated immediately beneath and in a line with a diagonal slit, firmly pressing the pasted and folding edges together, depositing the bag now formed upon traveling tapes, which convey it to the drying-cylinder.
WVe would observe that by the above arrangement of mechanism various sizes of cupshaped or tl1ree-cornered bags may be made in one machine, the speed of the cutting-rolls and the width of the paper determining the size of the bag.
In the accompanying drawings, Figure l is a side elevation, and Fig. 2 a plan, of a machine for the manufacture of cup-shaped or triangular bags during the continuous and uninterrupted traverse of the paper through the machine. Fig. 3 represents a paper blank with a narrow fold, when severed. Fig. 4 represents a similar View, indicating by dotted lines the direction of the final crease. Fig. 5 is an enlarged view of the bag as being finally closed and finished. Fig. 6 is a sectional elevation showing the position of the various sets of rolls, the gearing being excluded with a view to render the description of the said rolls and their respective functions more intelligible. Figs. 7 and 8 are respectivelyside and end elevations of a pair of elliptical or eccentric wheels and the manner of adjusting the same to the' speed or traverse of the paper at the time of severing the paper blank.
Referring to Figs. 1 and 2, A is the frame work of the machine, B a reel of papenfrom which bags are subsequently assumed to be made. The paper, in passing into the machine, is made to overhang at the margin the end or edge of roller O to the extent of about five-eighths of an inch, so as to cause a deflection of the overhanging margin, which is then gradually turned under the traversing paper by guide-fingers O and C until it is finally laid flat with the fold on the top of the traversing sheet of paper when passing over the guide-roller C on its way to the drawrollers D and D. The paste-disk E deposits a continuous streak of paste along the upper surface of the narrow fold while passing over ICO guide-roller G and to prevent the paste so of the narrow fold may consist of paste-trough F, in which revolves the paste-disk F, onthe' arbor of which is fixed ratchet-wheel F This wheel is actuated by-catch F joined to one; "end'of-the leverFfl the otherend of which is actednponby 'the-revolving cam F secured i toshaft-G. To'thisshaftis also secured the paste point 'or finger G, which,:revol-vin g, rej ceives from the-disk F a suppl-yof 13355136,. which'is transmittedwithin the crease of'the narrow fold of eachbag-lengthbeforethe'fold i-s'fin-ally laid and at a pointwhich will subsequent yformthe tip or bottom of the bag.
-Wewill nowdesc'ribe the-varied functions; of the-several rolls andthe knife or "folding edgefor'the production of bags of a triangular or three-cornered shape in a continuous, The first-set of; rolls 1) and D draws the paper from the -reel The paper thus drawn and uninterrupted manner.
13 into the machine. is "severed into bag-lengths or sheet-blanksby the second pair of rolls H and .11. Each; blank when-severedis then carried forward by'the third pair of 'rolls'I and 'I, andimme-i "diatelyafter its liberation from thesaid'rolls it is struck -bythe knife -or folding edge Ji (seen in Fig. 2)througha diagonally-disposed slit formed in-the plate J. 'By this operation; the baglength becomes creased diagonally on the *line indicated Fig.4 and is deposited between the bite of the rolls J 2 and- J thetwo triangular halves -K and K of the blankbeing folded one over-the other, asseen in Fig. 5, to complete the bag.
The knife or folding edge J, as seen in" Fig. 2, is attached to-arms-L and L secured to shaft'L, from which projects upward a le-; ver connected by a rod L to a vertical lever L (Seen in'Figs. 1 and 2.) '10 the shaft carrying thelever L is secured another lever carryingat it-souter 'end a'bowl, actingi the recess of the heart-shaped cam L so as to suddenly depress the knife or folding edge J at the proper time to form the final crease.
VVewould'here observe that with the exception of'thecutting-rolls II and-H the several sets orpairs of rolls above enumerated are arranged to revolve continuously in the same direction-and at the same surface speed. If desired, however, the last set of rolls J and J 3 may have imparted to them anaccelerated speed todeliver the finished bags upon the traveling tapes clear and out of the way of 'those'behind and may be actuated by means of endless cord 0 and guide-pu1leys P from grooved pulley Q, fixed to driving-shaft R. The cutting-rolls, which are irregular but continuous in their motion, are held out of contact with each other by a projecting rim at each end of the rolls, so that the cuttingedges only are brought together and then only during'the severance of the bag-length. (See Fig. 6.) This irregularity in the motion may be effected bya'pair of elliptical or eccentric wheels M and M, which may be adjusted to increase or diminish the speed of the cuttingrolls immediately before-and during the severance of the bag-length and "in accordance 'withthe'spee'd or traverseof the paperthrough the machine when increasing or diminishing the bag-length, ashereinaft-er explained.
Theeccentri'c-wheel M is in gear with corresponding wheeliMQ to-whichiscaster-fixed disk-plate P,'having an annular dovetailed recesssunk'i'n 'itsfac'e, in which is fitted'the "edgesof the-'bolts'S and S. (Seen in Figs.'-7
and 8.) These bolts proj eet throughholes'in disk-plate P keyed to the arboro'f the roll 11, so that by'tighteningthe nnt s'S ands 'the'two disk-plates and the eccentric-wheel M become firmly secured to the arbor-0f the roll 11.. When the eccentric M requires adjustmen't, as and for the purpose above de- =scribe"d,the nuts S and S are slackene'd and the eccentric-wheel M moved to a -suitable position on'thearbor of the roll H, when the nuts are again tightened to secure the parts together.
In all'cases the cutting-rolls are made 'to sever a bag-length at-each 'revolutiorn'and to increase or diminish the bag-length it is then requisite to substitute for change-wheel N (seen in TigsJl-and 2) another of a smaller or larger diameter, when the speed of the cutting-rolls and-the movement of the fold-' ing-edge'will be simultaneously affected. 'When, however, any alteration in the speed of the cutting-rollers'is effected by the substitution-of a change 'wheel, as above described, the eccentric-wheel M will require to be moved or turned'upon the arbor of the cutting-roll H at the same timeto'bring the cutting-edges of the rolls to the speed or traverse of the paper during'theseverance of the bag-length.
Having-now described our said invention, what-we claim as new, and desire to secure by Letters Patent, is-
'1. In a machine for the manufactureof triangular-shaped bags, the combination of creasing-roll O and paste finger or point G, by whichpaste is deposited at intervals within the crease of the narrow fold, substantially as and for the purpose speciiied.
2. In a machine for the manufacture of triangular or three-corner-shaped bags, the combination of the cutting-rolls II and H, the eccentric-wheel M, the eccentric-wheel M, adjustably connected 'with one of the cutting-rolls for increasing or diminishing the speed of the cutting-rolls before and during the severance of the bag-length, and the change-wheel device, substantially as described.
3. In a machine for the manufacture of triangular or three-eorner-shaped bags, the combination of the cutting-rolls H and H,
one of which is provided with a plate P the.
eccentric-Wheel M, the eccentric-wheel M, provided with a plate P, mounted on the plate secured to the roll, devices for adj ustro ing the plate of the eccentric-Wheel relatively to the plate on the roll for increasing or diminishing the speed of the cutting-rolls before and during the severance of the baglength, and a change-Wheel device, substantially as described. 15
