  • the frame of the machine may be of any suitable form to support the operating parts. As shown, it consists of the two side frames A, B in which the wrapping mechanism is mounted at thefront or delivery end of the machine, the pa- 1 per feeding mechanism at the rear end of the 1 machine, and the wrapper feeding and pasting mechanism in the upper part of the machine so as to feed the wrapper downward between the paper feeding and wrappingmechanism.
  • the feeding rollers consist of four series of narrow rollers or pulleys a, b, c, d, mounted respectively on shafts 10, 11,
  • the feeding rollers rotate in the samedirectiomas shown by the arrows in Figs. 4, 5 and 6, so that the paper is constantly advanced thereby, and the rollers are. preferably rubber faced or roughened, corrugated, or otherwise formed so as to give a better hold upon the paper.
  • the rollers may be arranged without overlapping but preferably are arranged to overlap each other slightly, as shown, less space being thus. left between the surfaces of successive series of Fig. 3 is a front or delivery end elerollers onthe line of engagement of the paper so that the paper is thus engaged through a greater portion of its length and a better feed secured.
  • the rollers may be arranged so as to form a complete or substantially complete circle, and engage the rolled paper on all sides,
  • I preferably inclose the wrapping space by the rollers only sufficiently to secure the proper feeding of the paper and combine them with one or more guides by which the paper is properly directed.
  • These guides may be rigid and mounted in fixed positions but preferably are spring pressed so as to yield slightly as the paper is rolled up and thus hold the paper uu-,
  • rollers may be used with or in place of the plate guides shown, if desired.
  • the guides e are carried by arms 14 on a rock shaft 15, which has upon one side a crank arm 16 connected toa rod 17 sliding in bearings 18 in the frame and spring pressed by a spring 19 soas to keep the shaft 15 under constant spring pressure tending to and the shaft is rocked in the opposite direction against the tension of spring 19 so as to enlarge the wrapping space and loosen the wrapped paper for delivery by means of a crank arm 20 carried by the rock shaft and actuated through a pitman 21 by cam 22 carried by the main shaft 0 of the machine, the
  • pitman 21 being provided withka bowl 23 engaged by the cam 22 in its rota ion.
  • rollers a, b, c at will advance the paper without guides between the different series, but to secure greater certainty of action, especially at high'speeds, I preferably use guides bridging over the narrow spaces between the parts of the. rollers by which the paper is engaged. It is desirable also that means should be provided for moving the wrapped paper sidewise out of thegrip of the rollers for delivery, and in the construction shown I employ a series of curved guides extending from rollers 12 to rollers d, and use these guides with suitable actuating devices as a convenient means for releasing the wrapped paper from the rollers.
  • These curved guides f extend very slightly inside the space formed between the rollers a, b, c, d so as to guide the leading end of the paper between the rollers b, c, d, and are thrown inward so as to movethe wrapped paper sidewise for its deliver being mounted upon arms 24 carried by rock shaft 15, previously described, so that as this shaft is rocked by cam 22 against the tension of spring 19 and theguides c are thrown outward to loosen the wrapped paper, the guides 24 are simultaneously thrown slightly inward so as to press the paper out of the grip of the rollers, as shown in Fig. 6. Itwill be understood however, that the guides f may be stationary, and other means be used for releasing the paper from the rollers, or either feature may be used'without the other, although both are desirable.
  • rollers 60, b, c, d are mounted in fixed positions relatively to each other, and the wrapped paper is delivered therefrom by moving it endwise from between the rollers.
  • Any suitable device may be used for this purpose, but I have shown a simple and efficient construction in which the end of the wrapped paper is engaged by an ejector g carried by a sliding bar or plunger 25 mountedin the side frame A and a bracket 26 supported thereon.
  • This plunger 25 carries pins 27 which are engaged by a forked lever 28 pivoted on a bracket 29 at the base of the frame A, and the lever is normally pressed inward toward the frame A by a coiled spring 30 secured to the frame and lever, and forced outward against the tension of spring 30 by adisk cam D carried by the main shaft (3 and engaging a bowl or roller on the lever 28.
  • the cam D is preferably formed as shown, so as to withdraw the ejector g from the end of the wrapped paper slightly for the delivery operation, and then release it suddenly so as to allow the spring 30 to draw the lever 28 intoward the frame A and actuate the ejector to give the end of the paper a sharp blow sufficient to drive it out from between the rollers at the opposite side of the machine.
  • the cam D may be formed, however, so as to hold the ejector against the paper until the lever is released for the delivery movement but the construction shown is preferable.
  • This interior guide may be formed and supported in anysuitable manncrand may be used at one or both side edges, but in the construction shown employing an ejector for removing the wrapped paper, it is preferably formed by a projection it carried by the ejector and may be made cone shaped, as shown, so as to guide the ejector during its delivery movement, when the latter is withdrawn from the paper before delivery as above described, and
  • Figs. 1 to 8 only the interior guide carried by the ejector is used, but in Fig. 13 is shown a modification employing a similar guide at the opposite edge of the paper, this guide h being carried by swinging arm lOl actuated by a cam D on the shaft 0, which is timed so as to withdraw the guide It just before the paper is delivered by the ejector.
  • this guide may be mounted and actuated "by any other suitable means.
  • any suitable paper and wrapper feeding devices may be combined to form a high speed automatic wrapping machine, and the wrappers may be previously pasted or a pasting mechanism added to paste the wrappers in the machine.
  • this wrapping mechanism is well adapted to be combinedwiththetinal foldingdevices of afolding machine or printing press of any of the commonforms sothat the papersarereceivedtherefrom by the wrapping mechanism, suitable wrapper feeding and pasting devices being added.
  • the holder E for the papers or pamphlets is mounted on the rear end of the machine, and the bottom paper is fed from the .holder over guides 40 to feeding belts 31 carried by rolls 32, and by these belts advanced to the wrapping mechanism.
  • the paper is fed from the holder by a series of pivoted lingers 33 carried by slide 34E moving'on rods 35 mounted in the frame of the machine, and pressed upward by springs so as to engage the bottom paper when withdrawn.
  • the slide 34 is reciprocated upon the rods 35 to ad- Vance the papers in proper time by means of slotted levers 36 carried by rock shaft 37 mounted in the side frames A, B and operated from the main shaft 0 by means of a pitmau 38 connected to one of the levers 36, and an eccentric 39 on the shaft 0.
  • the wrappers are cut from the web, pasted and fed to the wrapping mechanism by the following means:
  • the wrapper web y is fed from the web roll F at the top of the machine by a pair of feeding rolls 42 to a pair of cutting and feeding rolls 43 by which the wrappers are severed from the web and advanced downward to the wrapping mechanism between guides 44, a line of paste being applied to the rear end of each wrapper between the guides 44 by paster 45 co-acting with a roll 46, the paster receiving paste from a'fountain roll 47 mounted in fountain A8 in the usual manner.
  • the wrapper y is fed downward between.
  • rollers 49 are held against the lower belt roll 32 under yielding spring pressure, and that, when the guides eand rollers 49 are pressed backward slightly as the paper is rolled up, as previously described, the rollers 49 are raised slightly so as to relieve the feeding pressure between these rolls and the belt roll 32 and belts 31. It will be seen also that the upper forward belt roll 32 is so located as to press not uponthe lower belt roll but upon the lower series of belts 31 some distance from their belt roll, thus giving a yielding or elastic feeding hold upon the paper.
  • the feeding devices by which the papers or other publications are fed to the wrapping devices may be so nicely adjusted as to bind thereon with suiiicient force to insure the prompt and regular feed of the papers and still permit this slip above referred to, it is preferable to provide more positive means for feeding the papers into the control of the rolling devices, and provide for relieving the pressure, wholly or partially, at the proper time so as to permit the movement of the plies of the paper upon each other as they assume the cylindrical form.
  • rollers are raised to relieve the feeding pressure by m'ounting them on a spring pressed support, and raising them by the pressure of the paper, and this will be found a simple and efficient constructiomit will be understood that-the rolls may be mounted in any other suitable manner, and that any other suitable means may be used for moving the rolls so as to relieve the feeding pressure at the proper time.
  • the operative parts of the machine with the exception of the fingers for advancing the bottom paper w from the holder E to the belts 31 are driven from the main shaft 0 as followsz-
  • the shaft 0 carries a large gear 50 which meshes with a gear 51 on the shaft of the front belt roll 32, and the rear belt roll 32 is driven therefrom by the belts 31 and drives the shaft of the rear belt pulleys directly by gears 52.
  • the shaft of the forward belt roll 32 carries outside the frameA a gear 1 by which the shaft lO-carrying the first sew ries of rollers a is driven through an intermediate 2 and a gear 3 on shaft 10.
  • This gear 3 on shaft 10 meshes with a gear 4 loose on the shaft 11 carrying rollers b, and this gear 4 engages a gear 5 carried by shaft 12 of rollers c.
  • the gear 5 on the shaft 13 meshes with a broad faced intermediate 6 which meshes also with a broad faced gear 7 carried by shaft 13 of rollers
  • the broad faced gear 7 on shaft 13 meshes with a gear 8 loose on shaft 12, and this loose gear 8 meshes with a gear 9 on shaft 11.
  • shaft 13 For driving the wrapper feeding, cutting and pasting mechanism, shaft 13 carries outside the frame B a small gear 53 which drives the feeding and cutting rolls 43 through intermediates 54, 55, and gears 56 on the roll shafts.
  • the feeding rolls 42 are driven from one of the feeding and cutting rolls 43 by gear 57 on the shaft, intermediate 58 and gears 59 on rolls 42, and the paster 45 and fountain roll 47 are driven from gear 57 through intermediates and gears 61, 62 on the shafts of the paster and fountain roll respectively.
  • the wrapper may be led in with the paper or at any suitable point in the wrapping, but the parts are preferably timed, as shown, so that the paper a: is advanced to the wrapping mechanism and partially rolled and as the rear end of the paper is about to be drawn in, the wrapper y is led in beneath the pulleys 49 and thus held between the layers of paper, the length of the wrapper being such that the rear pasted end of the wrapper-overlaps upon the layer of wrapper previously upon the paper for pasting after the paper and wrapper are fully rolled.

It will be understood however, that the timing of the parts may readily be varied, so as to roll the paper and wrapper during more or. less rotations of the rollers.
  • paper a is just being advanced to the wrapping mechanism by the feeding belts 3l,belt roll 32 and pulleys 49, the guide 71. is in position so that the leading end of the paper is led beneath the same inside the ejector g, and the guides e,f are held in the proper position to aid in rolling the paper by the spring 19 acting on the rock shaft 15, the bowl 23 on pitman 21 being now on the lowest part of the cam 22.

  • the guide 6 guides the leading end of the paper under spring pressure, and that the paper is thereby held under spring pressure during the entire rolling operation after the leading end of the paper has reached the guide e' on its first rotation, the guide ebeing then pressed back slightly by the leading end of the paper As shown in Fig. 4 the so as to put the spring 17 undertension, if the matter being wrapped be of some thickness and rigidity, as in the case of publications having a number of leaves or plies.
  • the feeding rollers L9 are raised slightly so as to relieve the feeding pressure upon the body of the paper,- thus permitting the slip of the plies upon each other required for the unequal movements of the inner and outer portions of the paper as above described. If the paper be of such length that the roll is still within the range of action of belt roll 32, the slight yielding grip of this roll and belts 31 upon the rear end of the paper also permit this slip.

  • the wrapper y is fed' in between the layers of paper so as to be rolled up therewith during the whole or a part of the second rotation.
  • the paper is fully rolled and the wrapper partially wound during the second rotation of the feeding rollers, and as the wrapper is fully wound and secured by the pressure of the guides and rollers thereon, the higher part of the cam 22 engages the bowl 23 on pitman 21 and rocks shaft 15 against the tension of spring 19 so as to carry the arms 14:, 24:, and guides e,f to the left from the position shown in Figs. 5 and 7 to that shown in Figs. 6 and S the guides 6 thus being carried away from the pulleys so as to enlarge the wrapping space and loosen the paper while at the same time the guides f operate to move the wrapped paper slightly out of the grip of the rollers a, cl, so that the wrapped paper then rests freely on the lower rollers a.
  • the frames 63 are rocked at the proper time by the following means:
  • the main shaft 0 carries a large face cam G provided with a groove in which runs a bowl 64 carried by a pitman 65 connected to a crank arm 66 on a rock shaft R mounted in frames A, B.
  • This rock shaft carries at each side of the machine a segmental gear 67 which meshes with a segmental gear 68 on the frame 63 on shaft 10 carrying shaft 11, and this frame carries similar segmental gears 69 which engage corresponding gears 70 on the upper frame 63 on shaft 13 carrying shaft 12 and rollers c.
  • the guides e carried by arms 14 on rock shaft 15 are pressed forward toward the beltpulleys by spring pressed rod 17, and the guides e and rollers 49 are pressed back by the paper during wrapping and operate as in theconstructiou previously described, but the guides are not positively withdrawn as before but are so mounted and arrangedflthat as they are pressed rearward and the spring 19 put under tension as the paper is rolled up, the tension of the spring thus produced is utilized in delivering the paper by throwing the guides forward as the wrapped paper is released, thus forcing the wrapped paper out sidewisefrom between the separated rollers b, c.
  • any suitable means may be used for this purpose, but I have shown a pair of rolls H mounted respectively above and below the lower set of feeding tapes 31, one of these rolls being provided with a blade 71, and the other with a groove 72 to receive the blade, so that the leading end of the paper is pressed into the groove as it is advanced to the wrapping mechanism and thusbent upward slightly.

I may, however, emwrapping, or folding and wrapping machine, ploy feeding belts in place of the rotating rollor the wrapping mechanism may be combined ers, these belts being combined with suitable with the ordinary forms of folding and delivering mechanisms now in use in printing presses, so that the papers may be printed, folded, wrapped and delivered by a single machine, my improved wrapping mechanism being of sufficient capacity to be applicable to high speed web printing presses.
In the accompanying drawings forming a part of this specification, I have shown for the purpose of illustration a complete independent wrapping machine which will be found a simple and eflicient embodiment of the present invention, and certain modifications of the wrapping mechanism, and a detailed description of the same will nowbe given, and the features forming the invention specifically pointed out in the claims.
In the drawings-I igure 1 is a side elevation of the machine. Fig. 2 is a horizontal section.
vation. Fig. 4 is a section taken inside the Figs. 5. and 6 are detail views similar to Fig. 4.011 an enlarged scale, showing the wrapping ands, respectively, of Figs. 5 and 6. and 10 are sections showing in different positions a wrapping mechanism of a modified form in which the paper is delivered sidewise from the separated rollers. Figs. 11 and 12 are sections showing in different positions a wrapping mechanism in which belts are used 3 as the feeding devices, and the paper is de- "livered sidewise from the separated belts.
Fig. 13 shows a modification hereinafter re-v throw the guides e inward toward the rollers,
ferred to.
Referring to said drawings, the frame of the machine may be of any suitable form to support the operating parts. As shown, it consists of the two side frames A, B in which the wrapping mechanism is mounted at thefront or delivery end of the machine, the pa- 1 per feeding mechanism at the rear end of the 1 machine, and the wrapper feeding and pasting mechanism in the upper part of the machine so as to feed the wrapper downward between the paper feeding and wrappingmechanism.
In the construction shown in Figs. 1 to 8, in which rollers are used as the feeding devices for rolling the paper and the paper is delivered endwise, the feeding rollers consist of four series of narrow rollers or pulleys a, b, c, d, mounted respectively on shafts 10, 11,
12,13, and arranged in circular form so as to provide a wrapping space between them within which the paper is wrapped. The feeding rollers rotate in the samedirectiomas shown by the arrows in Figs. 4, 5 and 6, so that the paper is constantly advanced thereby, and the rollers are. preferably rubber faced or roughened, corrugated, or otherwise formed so as to give a better hold upon the paper. The rollers may be arranged without overlapping but preferably are arranged to overlap each other slightly, as shown, less space being thus. left between the surfaces of successive series of Fig. 3 is a front or delivery end elerollers onthe line of engagement of the paper so that the paper is thus engaged through a greater portion of its length and a better feed secured. The rollers may be arranged so as to form a complete or substantially complete circle, and engage the rolled paper on all sides,
but I preferably inclose the wrapping space by the rollers only sufficiently to secure the proper feeding of the paper and combine them with one or more guides by which the paper is properly directed.
In the construction shown, I arrange on the side at which the paper is received a series of curved guides e which act to guide the leading end of the paper onward in the circular path as it is advanced to the guides from I the rollers at and direct the leading end to rollers a for the commencement of the second rotation. These guides may be rigid and mounted in fixed positions but preferably are spring pressed so as to yield slightly as the paper is rolled up and thus hold the paper uu-,
der constant pressure, and mounted andactuated so as to be withdrawn slightly from the fully wrapped paper, the wrapping space thus being enlarged and the paper .loosened for delivery. It will be understbod that rollers may be used with or in place of the plate guides shown, if desired.
As shown, the guides e are carried by arms 14 on a rock shaft 15, which has upon one side a crank arm 16 connected toa rod 17 sliding in bearings 18 in the frame and spring pressed by a spring 19 soas to keep the shaft 15 under constant spring pressure tending to and the shaft is rocked in the opposite direction against the tension of spring 19 so as to enlarge the wrapping space and loosen the wrapped paper for delivery by means of a crank arm 20 carried by the rock shaft and actuated through a pitman 21 by cam 22 carried by the main shaft 0 of the machine, the
pitman 21 being provided withka bowl 23 engaged by the cam 22 in its rota ion.
The rollers a, b, c, at will advance the paper without guides between the different series, but to secure greater certainty of action, especially at high'speeds, I preferably use guides bridging over the narrow spaces between the parts of the. rollers by which the paper is engaged. It is desirable also that means should be provided for moving the wrapped paper sidewise out of thegrip of the rollers for delivery, and in the construction shown I employ a series of curved guides extending from rollers 12 to rollers d, and use these guides with suitable actuating devices as a convenient means for releasing the wrapped paper from the rollers. These curved guides f, as shown in Fig.4, extend very slightly inside the space formed between the rollers a, b, c, d so as to guide the leading end of the paper between the rollers b, c, d, and are thrown inward so as to movethe wrapped paper sidewise for its deliver being mounted upon arms 24 carried by rock shaft 15, previously described, so that as this shaft is rocked by cam 22 against the tension of spring 19 and theguides c are thrown outward to loosen the wrapped paper, the guides 24 are simultaneously thrown slightly inward so as to press the paper out of the grip of the rollers, as shown in Fig. 6. Itwill be understood however, that the guides f may be stationary, and other means be used for releasing the paper from the rollers, or either feature may be used'without the other, although both are desirable.
In the construction now being described, the rollers 60, b, c, d are mounted in fixed positions relatively to each other, and the wrapped paper is delivered therefrom by moving it endwise from between the rollers. Any suitable device may be used for this purpose, but I have shown a simple and efficient construction in which the end of the wrapped paper is engaged by an ejector g carried by a sliding bar or plunger 25 mountedin the side frame A and a bracket 26 supported thereon.
' This plunger 25 carries pins 27 which are engaged by a forked lever 28 pivoted on a bracket 29 at the base of the frame A, and the lever is normally pressed inward toward the frame A by a coiled spring 30 secured to the frame and lever, and forced outward against the tension of spring 30 by adisk cam D carried by the main shaft (3 and engaging a bowl or roller on the lever 28. The cam D is preferably formed as shown, so as to withdraw the ejector g from the end of the wrapped paper slightly for the delivery operation, and then release it suddenly so as to allow the spring 30 to draw the lever 28 intoward the frame A and actuate the ejector to give the end of the paper a sharp blow sufficient to drive it out from between the rollers at the opposite side of the machine. The cam D may be formed, however, so as to hold the ejector against the paper until the lever is released for the delivery movement but the construction shown is preferable.
If the paper or pamphlet to be wrapped has unfolded or trimmed side edges no interior guide is required and it will be found also that such a guide is not essential even in wrapping publications with folded side edges. In the latter case, however,I prefer to use an interior guide projecting within the folded edge slightly, thus preventing the objectionable buckling or creasing which might otherwise occur, especially at high rates of speed. This interior guide may be formed and supported in anysuitable manncrand may be used at one or both side edges, but in the construction shown employing an ejector for removing the wrapped paper, it is preferably formed by a projection it carried by the ejector and may be made cone shaped, as shown, so as to guide the ejector during its delivery movement, when the latter is withdrawn from the paper before delivery as above described, and
insure its proper engagement with the paper,
the apex of the cone entering the space left in the interior of the paper in rolling.
In the construction shown in Figs. 1 to 8, only the interior guide carried by the ejector is used, but in Fig. 13 is shown a modification employing a similar guide at the opposite edge of the paper, this guide h being carried by swinging arm lOl actuated by a cam D on the shaft 0, which is timed so as to withdraw the guide It just before the paper is delivered by the ejector. It will be understood that this guide may be mounted and actuated "by any other suitable means.
With this wrapping mechanism any suitable paper and wrapper feeding devices may be combined to form a high speed automatic wrapping machine, and the wrappers may be previously pasted or a pasting mechanism added to paste the wrappers in the machine. It will be understood, also, that this wrapping mechanism is well adapted to be combinedwiththetinal foldingdevices of afolding machine or printing press of any of the commonforms sothat the papersarereceivedtherefrom by the wrapping mechanism, suitable wrapper feeding and pasting devices being added. For the purpose of illustrating a complete machine, however, I have shown paper and wrapper feeding and wrapper pasting devices of a common form, the previously folded papers being fed from a box or holder, and the wrappers fed from the web. In this construction the holder E for the papers or pamphlets is mounted on the rear end of the machine, and the bottom paper is fed from the .holder over guides 40 to feeding belts 31 carried by rolls 32, and by these belts advanced to the wrapping mechanism. The paper is fed from the holder by a series of pivoted lingers 33 carried by slide 34E moving'on rods 35 mounted in the frame of the machine, and pressed upward by springs so as to engage the bottom paper when withdrawn. The slide 34 is reciprocated upon the rods 35 to ad- Vance the papers in proper time by means of slotted levers 36 carried by rock shaft 37 mounted in the side frames A, B and operated from the main shaft 0 by means of a pitmau 38 connected to one of the levers 36, and an eccentric 39 on the shaft 0.
The wrappers are cut from the web, pasted and fed to the wrapping mechanism by the following means: The wrapper web y is fed from the web roll F at the top of the machine by a pair of feeding rolls 42 to a pair of cutting and feeding rolls 43 by which the wrappers are severed from the web and advanced downward to the wrapping mechanism between guides 44, a line of paste being applied to the rear end of each wrapper between the guides 44 by paster 45 co-acting with a roll 46, the paster receiving paste from a'fountain roll 47 mounted in fountain A8 in the usual manner. The wrapper y is fed downward between. the guides 44.- so as to reach the paper a: just above the lower front belt roll 32, and a se- ITO ries of rollers or pulleys49 carried by the arms 14 oo-act with this belt roll to advance the paper to the first series of rollers a, and to advance the wrapper with the paper until it is securely held between the layers of the partially wrapped paperso as to be drawn forward therewith. I
It will be seen that the rollers 49 are held against the lower belt roll 32 under yielding spring pressure, and that, when the guides eand rollers 49 are pressed backward slightly as the paper is rolled up, as previously described, the rollers 49 are raised slightly so as to relieve the feeding pressure between these rolls and the belt roll 32 and belts 31. It will be seen also that the upper forward belt roll 32 is so located as to press not uponthe lower belt roll but upon the lower series of belts 31 some distance from their belt roll, thus giving a yielding or elastic feeding hold upon the paper. While any other suitable construction of feeding devices for advancing the papers to the rolling devices may be used with matter consisting of a limited number of leaves or plies, this construction of feeding mechanism has a special function in connection with the rolling and wrapping of matter having many leaves or plies. In rolling such matter, it is obvious that the outer and inner surfaces must travel unequally, and in rolling a paper orother publication of many plies into a cylinder of small diameter, this difference of travel is so great as to render it important that the machine should be so constructed that the outer portion of the publication may slip upon theinner to permit'this difference of travel during rolling. While the feeding devices by which the papers or other publications are fed to the wrapping devices may be so nicely adjusted as to bind thereon with suiiicient force to insure the prompt and regular feed of the papers and still permit this slip above referred to, it is preferable to provide more positive means for feeding the papers into the control of the rolling devices, and provide for relieving the pressure, wholly or partially, at the proper time so as to permit the movement of the plies of the paper upon each other as they assume the cylindrical form. This result is attained in the construction shown, in which the rollers 49 00-21011 as'feeding rollers with the belt rolls 32 and belts 31 to advance the paper positively during the first part of the rolling of the paper, but are slightly raised from the belt roll and belts to relieve the feeding pressure, as soon as the leading end of the paper has been curved and directed against the guide e, at which time it is desirable that the outside plies should be free to move faster than the inner plies, and thus this raising of the rollers '49 permits the unequal movement of the plies of the paper-betweenthem and the rolls 32 and belts 31, while at the same time the-yielding pressure between the upper fed machine, as otherwise the paper must be held and fed forward by hand a considerable length of time to insure its proper advance by the rollers a, b, 0, d, while by the use of the rollers 49,32 it is necessary only that the leading end of the paper he presented thereg to, and in such hand fed machines, also, it is evident that this special feature of the release of the pressure of the rollers 49 should be included if thick publications are to be wrapped.
While I have shown only a construction in which the rollers are raised to relieve the feeding pressure by m'ounting them on a spring pressed support, and raising them by the pressure of the paper, and this will be found a simple and efficient constructiomit will be understood that-the rolls may be mounted in any other suitable manner, and that any other suitable means may be used for moving the rolls so as to relieve the feeding pressure at the proper time.
The operative parts of the machine with the exception of the fingers for advancing the bottom paper w from the holder E to the belts 31 are driven from the main shaft 0 as followsz-The shaft 0 carries a large gear 50 which meshes with a gear 51 on the shaft of the front belt roll 32, and the rear belt roll 32 is driven therefrom by the belts 31 and drives the shaft of the rear belt pulleys directly by gears 52. The shaft of the forward belt roll 32 carries outside the frameA a gear 1 by which the shaft lO-carrying the first sew ries of rollers a is driven through an intermediate 2 and a gear 3 on shaft 10. This gear 3 on shaft 10 meshes with a gear 4 loose on the shaft 11 carrying rollers b, and this gear 4 engages a gear 5 carried by shaft 12 of rollers c. The gear 5 on the shaft 13 meshes with a broad faced intermediate 6 which meshes also with a broad faced gear 7 carried by shaft 13 of rollers The broad faced gear 7 on shaft 13 meshes with a gear 8 loose on shaft 12, and this loose gear 8 meshes with a gear 9 on shaft 11. By this train of gears the series of rollers a, b, c, d are driven in the same direction and at the same rate of speed. 1
For driving the wrapper feeding, cutting and pasting mechanism, shaft 13 carries outside the frame B a small gear 53 which drives the feeding and cutting rolls 43 through intermediates 54, 55, and gears 56 on the roll shafts. The feeding rolls 42 are driven from one of the feeding and cutting rolls 43 by gear 57 on the shaft, intermediate 58 and gears 59 on rolls 42, and the paster 45 and fountain roll 47 are driven from gear 57 through intermediates and gears 61, 62 on the shafts of the paster and fountain roll respectively.
The operation of the machine will be understood from a brief description in connection with the drawings.
The wrapper may be led in with the paper or at any suitable point in the wrapping, but the parts are preferably timed, as shown, so that the paper a: is advanced to the wrapping mechanism and partially rolled and as the rear end of the paper is about to be drawn in, the wrapper y is led in beneath the pulleys 49 and thus held between the layers of paper, the length of the wrapper being such that the rear pasted end of the wrapper-overlaps upon the layer of wrapper previously upon the paper for pasting after the paper and wrapper are fully rolled. The cam Dis timed so as to hold the ejector in position with the guide 77. within the paper until the wrapping operation is substantially completed and then withdraw the ejector and release it for the delivery operation, withdrawing it again to its normal wrapping position in time for the next paperJ As shown the machineis adapted to roll the paper and wrapper during about two and one-half rotations of the rollers at, b, 0, (Z, the rollers rotating three times to each delivery movement andthe cam D is timed to de liver the paper and return the ejector and guide to position again during the other half rotation of the rollers so that the leading end of the paper is received on the guide. It will be understood however, that the timing of the parts may readily be varied, so as to roll the paper and wrapper during more or. less rotations of the rollers. paper a: is just being advanced to the wrapping mechanism by the feeding belts 3l,belt roll 32 and pulleys 49, the guide 71. is in position so that the leading end of the paper is led beneath the same inside the ejector g, and the guides e,f are held in the proper position to aid in rolling the paper by the spring 19 acting on the rock shaft 15, the bowl 23 on pitman 21 being now on the lowest part of the cam 22. As the leading end of the paper reaches the firstseries of rollers Ct, it is ad van ced thereby, together with the push of the feeding belts 31, roll 32 and the pulleys 4:8 co-acting therewith, and the leading end of paper fed to and by the successive series of rolls 1), c, 01, being guided in a circular path thereby and by guides e,f, and at the end of the first rotation the leading end of the paper is carried inside the rear end of the paper as shown in Fig. 5, the folded side edge of the paper being supported and buckling prevented by the guide It, as shown in Fig.7. It will be seen that the guide 6 guides the leading end of the paper under spring pressure, and that the paper is thereby held under spring pressure during the entire rolling operation after the leading end of the paper has reached the guide e' on its first rotation, the guide ebeing then pressed back slightly by the leading end of the paper As shown in Fig. 4 the so as to put the spring 17 undertension, if the matter being wrapped be of some thickness and rigidity, as in the case of publications having a number of leaves or plies. As the guides e are thus pressed back, the feeding rollers L9 are raised slightly so as to relieve the feeding pressure upon the body of the paper,- thus permitting the slip of the plies upon each other required for the unequal movements of the inner and outer portions of the paper as above described. If the paper be of such length that the roll is still within the range of action of belt roll 32, the slight yielding grip of this roll and belts 31 upon the rear end of the paper also permit this slip. As
the rear end of the paper is about to be drawn in, the wrapper y is fed' in between the layers of paper so as to be rolled up therewith during the whole or a part of the second rotation. The pressure of the rollers 49 upon the guides 44 and the slight pressure of the rollers 49 upon the wrapper on the paper a; being sufficient to secure the advance of the leading end of the wrapper until it is grasped be tween the layers of the partially rolled paper. The paper is fully rolled and the wrapper partially wound during the second rotation of the feeding rollers, and as the wrapper is fully wound and secured by the pressure of the guides and rollers thereon, the higher part of the cam 22 engages the bowl 23 on pitman 21 and rocks shaft 15 against the tension of spring 19 so as to carry the arms 14:, 24:, and guides e,f to the left from the position shown in Figs. 5 and 7 to that shown in Figs. 6 and S the guides 6 thus being carried away from the pulleys so as to enlarge the wrapping space and loosen the paper while at the same time the guides f operate to move the wrapped paper slightly out of the grip of the rollers a, cl, so that the wrapped paper then rests freely on the lower rollers a. Meanwhile the cam D has rocked the lever 28 so as to move the ejector g and guide 71 outward a short distance against the tension of spring 30, and as the paper is loosened from the rollers and guides for delivery as above described, the sharp side of the depressed portionofthecamDcomesoppositethe bowl on lever 28 and, the lever being thus released, the spring 30 returns it quickly to position moving the ejector g inward against the end of wrapped paper and giving the latter a sufficient blow to throw it outward from between the pulleys and deliver it at the side of the machine. The position of the ejector and paper as the delivering movement of the ejectoris completed is shown in Fig. 8. The paper having been wrapped and delivered as described, the parts are returned to their normal wrapping positions as shown in Figs. 1 to 4;, and another paper or having meanwhile been fed forward from the holderE to the position shown in Fig. 4: is taken by the wrapping mechanism, and thus the operation is repeated.
It is evident that many modifications may be made in the construction shown and deused. Thus, while a simple and eflicientconstruction is produced by the end delivery, I may use a construction in which the papcris delivered sidewise from between two series of the feeding rollers, the rollers being separated at the proper time by suitable mechanism. Such a construction is shown in Figs. 9 and 10. In this construction the shafts '11, 12 of rollers or pulleys b, c are mounted in frames 63 formed by plates pivoted on shafts 10, 13 of rollers a,d at opposite sides of the machine, so that shafts 11, 12 may be moved in opposite directions in arcs concentric with shafts 10, 13 from which respectively they are driven. The frames 63 are rocked at the proper time by the following means: The main shaft 0 carries a large face cam G provided with a groove in which runs a bowl 64 carried by a pitman 65 connected to a crank arm 66 on a rock shaft R mounted in frames A, B. This rock shaft carries at each side of the machine a segmental gear 67 which meshes with a segmental gear 68 on the frame 63 on shaft 10 carrying shaft 11, and this frame carries similar segmental gears 69 which engage corresponding gears 70 on the upper frame 63 on shaft 13 carrying shaft 12 and rollers c. .In this construction, the guides e carried by arms 14 on rock shaft 15 are pressed forward toward the beltpulleys by spring pressed rod 17, and the guides e and rollers 49 are pressed back by the paper during wrapping and operate as in theconstructiou previously described, but the guides are not positively withdrawn as before but are so mounted and arrangedflthat as they are pressed rearward and the spring 19 put under tension as the paper is rolled up, the tension of the spring thus produced is utilized in delivering the paper by throwing the guides forward as the wrapped paper is released, thus forcing the wrapped paper out sidewisefrom between the separated rollers b, c. In this construction,I have shown also means forbendingthe leading end of the paperup slightly as itis advanced to the wrapping mechanism to aid in securing the proper advancement of the paper in a circular path by the rollers. This feature of bond ingthe leading end slightly may be used in connection with the guidef of the construction previously described, but I have shown a construction in which the guide f is omitted, the bending of the leading end aiding in securing the same results. Any suitable means may be used for this purpose, but I have shown a pair of rolls H mounted respectively above and below the lower set of feeding tapes 31, one of these rolls being provided with a blade 71, and the other with a groove 72 to receive the blade, so that the leading end of the paper is pressed into the groove as it is advanced to the wrapping mechanism and thusbent upward slightly. The operation of this construction will be understood from a brief description in connection with Figs. 9 and 10. In Fig. 9 the parts are shown on the second rotation of the rollers, with the wrapper just being fed in, the guide .9 having been pressed back by the rolled paper and the so as to rock the frames 63, and carry the rollers b, c apart, and the pressure upon spring 19 being thus released, the guides e are thrown forward slightly so as to aid in deliveringthe wrapped paper over rollers b, which operation is assisted also by the rotation of the rollers, the position of all the parts in thus delivering the paper being shown in Fig. 10. The paper having been delivered, the bowl 61 again passes onto the outer concentric part of cam G and the frames 63 and rollers b, c, are returned to and held in position for receiving and wrapping the next paper. I
In the constructions thus far described, roll: ers are used as the feeding devices by which the paperand wrapper are advanced and rolled during the wrapping operation, but any other suitable feeding devices may be used for this purpose, and the paper delivered either endwise or sidewiseas previously described.
In Figs. 11 and 12.1 have shown a simple construction in whichibelts are used as the feeding devices, suitable guides being combined therewith to secure the proper rolling of the paper-and wrapper, and the wrapped paper'is delivered sidewise between the separated belts, being I pressed outward by a guide as in the construction shown in Figs. 9 and 10. In this construction, the lowerset of feeding belts 31 arecarried downward from inner belt roll 32 so as to form a set of feeding belts 'm by which the paper is advanced and rolled in connection with the set of belts n running in the opposite direction on the opposite side of.
the wrapping space. a The feeding belts m are led from the inner feedingrolls 32 about a roll or series ofpulleys 71 and over a series of belt tightening pulleys 72 to the rear belt' roll 32. The belt roll 71 is mounted on arms 73 pivoted on and carried by arms74 on a rock shaft 75 mounted in the side frames of the machine and provided with a crank arm 76 attached to a pitman 77 which-slides in brackets 78 on the frame, and is pressed in one direction by a spring 79 and moved in the other-direction against the tension of spring 79 by a cam 80 carried by the main shaft C and engaging a bowl 81 on pitman 77. The ends of the arms 73 are connected to the lower ends of crank arms 74 by springs 82 by which the roll7l is drawn 'downward'so as to'hold the bolts 31 under tension, and the arms 73 normally rest on stops 83 carried by armsi74, this construcm in proper position as the roll 71 is withdrawn. The belts n are carried by belt rolls or pulleys S4, 85, the lower roll or pulleys 85 being mounted on arms 86 carried by arms 87 on rock shaft 88 and connected to the lower ends of arms 87 by springs 89, the arms 87 having stops 90, and the arms 86 carrying half of the guide 0, this construction corresponding to that previously described in connection with the roll or pulleys 71. The rock shaft 88 carries a crank arm 91 connected by aconnecting rod 92 to one of the arms 74 on rock shaft 75 previously described so that, as c the rock shaft 75 is rocked by cam 80 against the tension of spring 79 to carry the belt rollor pulleys 71 outward, the shaft 88 is rocked in the opposite direction so as to carry the belt roll 85 outward also and thus separate the two parts of the guide 0 and the belts, and permit the wrapped paper to drop or be pressed down-from between them. Another series of belts may be used running transversely to the belts m, n for advancing the paper from belts n to belts m, but I have shown and prefer to use a series of guides 19 by which the end of the paper is guided so as to be advanced and rolled properly by the two series of belts m, To. These guides 19 are carried by arms 98 on a rock shaft 9% provided with a crank arm 95 spring pressed by a spring 96 on a rod 97 sliding in brackets on the frame and connected to the crank arm, this spring operating to press the guides 19 normally downward against the paper being wrapped and the guides being pressed upward by the paper during wrapping so as to put the spring 96 under tension,'the operation being the same as previously described in connection with the corresponding parts in Figs. 9 and 10. The arm 93 also preferably carries a series of rolls 98 corresponding to rolls49 of the constructions previously described, which co-act with the belts m to aid in advancing the paper as Well as in feed-' ing the wrapper. A stop 99 is preferably used to stop the crank arm 95 as it is forced downward under the pressure of spring 96 and hold the guidesp and rollers 98 in proper position for the reception of the paper to be wrapped. The paper may be finally delivered direct-1y from the belts m, at, but I have shown a construction in which the wrapped paper is delivered upon a table H, preferably made hollow and heated in any suitable manner by steam or otherwise, over which the wrapped paper is advanced by a series of feeding belts 100, the-wrapper being thus thoroughly dried before final delivery by the heat, and the wrapped paper held in form and the wrapper pressed down during this operation by the pressure of the belts.
The operation of the construction will be understood from a brief description in connection with the figures. As shown in Fig. 11, the paperis nearly rolled and the rear end of the paper with the wrapper is just about to be drawn in, the guidesp have been pressed back so as to put the spring96 under tension and the bowl 81 is on the concentric portion of the cam 80, the two parts of the guide 0 being thus held together to form a guide extending between the belts m, n onthe lower side of the wrapping space. As the wrapping operation is completed and the pasted end of the Wrapper secured, the outer portion of the cam actuates the pitman 77 through bowl 81 so as to rock the shaft 75 and through the connecting rod 92 the shaft 88, and carry the belt rolls 71, and the two parts of the guide 0 in opposite directions from the position shown in Fig. 11 to that shown in Fig. 12
so as to separate the belt rolls and two' parts of the guide sufficiently to allow the paper to be delivered downward between them. As the wrapped paper is thus released the spring 96 through crank arm rocks the shaft 94 and throws the guides 19 downward so as to force the wrapped paper out onto the table II over which it is carried and delivered by belts 100. The bowl 81 then passes onto the lower concentric portion of cam 80, and the parts are all returned from the position shown in Fig. 12 to that shown in Fig. 11 .bythe pressure of spring 79 upon pitman 77.
It will be understood that other arrangements of the feeding devices for rolling the paper may readily be made by those skilled in the art without departing from my invention,and I am not to be limited to any of the specific arrangements shown.
