MACHINE FOR GRIMJPING PAPER AND THE LIKE.

Application filed June 26, 1913. Serial No. 775,e95.

To all whom it may concern Be it known that T, HARRY Q. BAs'rnn, a

citizen of the United States, residing at Benton Harbor, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Ma chines for Crimping Paper and the like, of which the following is a specification.

My invention relates to improvements in machines for crimping paper and the like, to prepare the same for use in a loose leaf book having mechanical bindings, the book being built up as occasion demands and the leaves therein being removable at pleasure. The loose leaf system is'well known and need not therefore be described herein.

To derive satisfactory results froma loose leaf book, the paper sheets being usually more or less stifi', it has been found necessary to give a high degree of flexure to the lead adjacent to its binding edge, and accordingly that portion of the leaf must be treated to accomplish that end; the width of the treated portion is somewhat dependent upon the thickness of the book. The purpose is to provide a leaf which will lie comparatively flat when the book is open, so that writing thereon maybe readily and satisfactorily done. The treated portion of theleaf is parallel with the binding edge and far enough removed therefrom to permit the mechanical binding to beapplied to the leaf between the edge and the treated portion thereof.

The preferable treatment of the leaf consists in forming a crease therein by folding in one direction along a line parallel with the binding edge, reducing the crease to flattened form, forming a crease along the same line in the opposite direction, and reducing said creased portion to a flattened form. As many such creasing operations as may be desired are performed, the creases being as close together as conditions may warrant or require, and formed with sufiicient pressure to break the calendered surface of the paper along the lines of creasing; the result is a comparatively flat portion of the sheet which has a high degree of flexure in the region thereof which is used as a hinge in turning the sheet to an open or closed position. The most satisfactory means for performing this operation, which as a Whole is given the name crimping, has hitherto required separate and distinct operations for producing each line of crimp; this is Specification of Letters Patent.

slow and consumes much time in performance. Much time is consumed also in feeding in the sheet to the mechanism and removing it, both of which take place from the same point; each sheet must be placed in the machine by the operator and retained there during the performance of the crimping,and then removed before another sheet can be inserted for treatment. Further, when the treated sheet comes from such machine it is ridged along the line where the crimping operation has taken place, and must then be placed into a press for flattening and restoring it toia comparatively smooth surface. Further, the adjustment required in adapting such machines to different thicknesses and degrees of stidness of different grades and kinds of paper, is difficult; also machines of the mentioned types are subject to such stresses in operation that their maintenance is expensive and their period of efficiency comparatively short.

My invention, hereinafter described, relates to a machine for performing the operation of crimping by a new and better process of rotary action. The machine is built preferably on the unit plan. One unit as hereinafter described will make one complete line of crimp.

The complete machine will usually comprise five units connected together. A feed table will be placed on the front of the first unit and a receiving table on the rear of the last unit, where several units are employed. The creasing mechanisms of these associated units are so placed that a sheet of paper passing through them will have formed upon it, parallel to its line of travel, a crimped or flexed area composed of five creased or folded lines, equidistant from veach other and parallel with each other. It

is understood, however, that as many units as desired may be employed to produce a crimped area of any given. number of creased lines at one feeding of the sheets, or that a crimped area of any number of creased lines parallel with each other and any desired distance apart, may, be produced with one unit only, by feeding the sheet through the machine for each lineof crimp wanted, the feed guide being adjusted each'time to secure the proper position of each of the desired lines."

The essential features of my invention confi fitfili t- In the use of two comparatively small creasing wheels which, rotate one against the other and between which the partiall folded paper is passed to complete the fol ing process with sufiicient pressure to produce the desired amount of flexure in the paper along the folded line, very similar in effect to the process of rubbing a bone folder along theline of fold; Second. An attachment for readily adjusting the amount of pressure exerted by the creasing wheels upon the line of fold in the paper whereby the pressure may be quickly and easily regulated to suit the needs for varying thicknesses and strengths of paper or other material to be treated. Third. A series of grooved and ribbed rollers employed to form a fold of. increasing depth and narrowness without damage to the sheet, whereby the fold is given the shape required to enter successfully the creasing wheels. Fourth. The attachment hereinafter referred to and described as the forming guide, designed to guide the sheet from one forming roller to the other and from the last forming rollers to the creasing wheels and to cause the sheet in its passage .to retain the form effected by the forming rollers. Fifth. An"; attachment which for the purpose of description is called the flattening or unflexin form; The function of the flattening or un exing form is to receive the folded portion passes from the creasing wheels, and to open the sheet out to a comparatively fiat position preparatory to entering the flattening or unfle ring rollers. In thea ccompanying drawings which are hereto attached and hereby made a part of this specification, Figure 1 illustrates the forming rolls and the creasing wheels; Fig; 2 shows the lateral guides for maintaining the fold given to the sheet of paper by the forming rolls; Fig. 3 is a view showing the vertical guide, and Fig. 3 is-a side view of the guide contained in Fig. 3; Fig. 4 is a view of a machine'unit with the left side as seen from the front removed to illustrate the general arrangement of the guide and forming means, and the creasing devices both upper and lower; Fig. 5 is an elevation of a unit as seen from the left; Fig. 6 is a vertical transverse section through a unit, the middle portion thereof being broken out, to illustrate the construction and operation of the lower creasing wheels; Fig. 7 is a vertical transverse section through a unit, bein broken away in the middle portion, to il ustrate the mounting and operation of the upper'creasing wheels; Fig. 8 is a top plan view of a unlt; Fi 9 is a top view of an enlarged detail of t e flattening form; Fig. 10 is a side View of the flattening form illustrated in Fig. 9; Fig. 11 is a magnified view of the forming rol s engaging a sheet of paper to show the grip by one sideof the of the sheet as the same rib against the adjacent wall of the groove so as to leave play on the opposite side of the rib which permits the paper to feed into the groove under the pressure of the rib entirely from one side.

Referring to the drawings, the supporting frame of a machine unit is clearly seen in Fig. 4 wherein 1 is the member resting upon the floor; 2 and 3 are the legs on one side of the machine at the ends, and 4 forms the body or bed of the machine. This may be formed in one piece or several pieces as desired; a similar supporting frame is located on the opposite side of the machine and the supporting frames are connected by means of the cross bars 5, 6, 7 and S which are secured to the legs in any desired manner. At the front end of the machine is the feeding table 9 having the adjustable guide 10 thereon, the table being supported on the bracket 11. At the farther end of the machine is a delivery table (not shown), and as hereinbefore stated the machine completed for operation may consist of a single unit, which is illustrated in the accompany-- ing drawings, or it may consist of a number of like units arranged tandem, the formin members of succeeding units being locate slightly out of line with the preceding ones, whereby as a sheet of paper passes from one unit to another the crimping operation takes place-along a line parallel with that operated upon in the last unit, and at such dista-nce therefrom as the desired arrangement provides. This arrangement of units will be clearly understood without illustration, inasmuch as all of the units are formed alike and operate in the same manner. It will be understood that a delivery table is placed at the rear end of the last unit of the series, and it is attached in the same manner as if there'were only a single unit I employed.

Mounted upon the frame work just described and journaled at 13 and 1a in the frame of the machine at one side, and at 15 and 16 on the opposite side are the feed rollers 17 and 18 which receive between them the aper being fed from the feeding table 9. aid rollers advance the sheet of paper horizontally to the first set of forming rolls 19 and 20, which are appropriately journaled on ofie side of the 22 in said frame, and on the opposite side of the machine at 23 and 24.

Referring to Fig. 1 four pairs of forming rolls are shown including 19 and 20, 25 and 26, 27 and 28, 29 and 30, which are appropriately journaled in the side frame of the machine on one side at 21 and 22 as stated, and 21 and 21 21 and 21, 21 and 21', and on the opposite side of the machine at 23 and 24 as stated, and 23 and 23", 23 and 23",

The sheet of paper 31 is advanced by the feed rolls to the forming rolls machine at 21 and 19 and 20; on roll 19 is formed a circumferential rib 32 adapted to engage in a circum-L ferential groove 33 formed in the roll 20, and as the paper advances it is pressed by the rib 32 into the groove 33, ing a fold 34 therein. As appears by reference to Fig. 11, the paper is gripped between the wall 35 and the curved face 36 of the rib 32 and held thereby against movement laterally. The space between the opposite face of the rib 32 and the opposite wall of the groove 33 is wider than the mere thickness of the paper demands, so that the paper on that side of the rib is free to move laterally and be depressed toward the bottom of the groove; consequently, as the said forming rolls rotate the paper is fed from the right into the groove, under the influence of the rib. This feature of construction is maintained in the succeeding forming rolls, and the sheet leaving rolls 19 and 20 passes on under the direction of guides which will be hereinafter described to the rolls 25, 26 which contain a deeper groove and a correspondingly higher rib, whereby the fold in the paper is deepened, and inasmuch as the rib and the groove are narrower, the fold will consequently be not only deeper, but the sides thereof will approach each other more closely. The sheet is then advanced to be engaged by the formingrolls 27, 28, the groove innroll 28 being somewhat deeper and narrower, and the rib being formed to correspond, so that as the paper asses from this set of rolls the fold forme therein is deeper and narrower than it was before entering them. The sheet then is advanced to rolls 29, 30 in which the groove is deeper and narrower and the rib correspondingly narrower and higher, whereby the fold formed in the paper by the three preceding sets of forming rolls is here narrowed and deepened. An inspection of the succeeding rolls illustrated in Fig. 1 makes it clear that the sides of the fold as produced by the last set of forming rolls approach each other much more closely than in the preceding stages of the formation ,of the fold. The sheet is then advanced from the last set of forming rolls 29, 30 to the lower creasing wheels 37, 38 which are arranged to receive between their creasing faces the fold from the rolls 29 and 30 and press the sides thereof together so as to produce a decided crease in the paper, as may be seen at-39.

The sheet is fed to the creasing rolls and maintained in proper adjustment during the creasing operation by means of the rolls 39, 39', shown particularly in Fig. 6. Upon leaving the creasing wheels the crease takes over a flattening form 40 which gradually widens and flattens, as appears especially in Figs. 9 and 10, the rolls 40 and 40 carrying the paper forward, and in the movement over said form the crease is spread out so ing rolls t1; and 4&2, whereb thereby formthat it maybe received between the flattenthe sheet of paper is reduced to practica 1y its original flattened form. The sheet is advanced through these flattening rolls to a set of forming rolls d3, 44%, the circumferential groove being located in the upper roll 43, v

while the rib an is formed on the lower roll 44:. As the paper is received between this set of forming rolls a fold therein projecting upwardly is produced on the same line on which the downwardly projecting fold was produced by the passage over the front part of the machine. Thence the paper is advanced to a second set of forming rolls 45, a6 where the fold is deepened and accordingly narrowed, and the sheet of paper then passes on to a third set of forming rolls 47, 48 where a greater depth and narrowness are imparted to the fold. The sheet is then advanced to the creasing wheels 4:9, 50 where I the fold is given a sharper creased form, whereby the calendered surface of the paper is again somewhat broken; the sheet is received by the feed rolls 49, 4-9 at the time it enters the creasing wheels, and is thereby held in proper adjustment during the creasing operation. The said rolls are especially illustrated in Fig. 7. Thence the sheet is advanced into engagement with the flattening form 51 over which the crease takes, and as the paper is advanced along the gradually expanding formby the feed rolls 52, 53 the crease is opened and somewhat flattened and is received between the flattening rolls 5t, 55, whereby the paper is given practically its normal flattened form and is then advanced either onto a delivery table or into a second unit as desired. If a number of units is connected up in series the paper thus doubly creased and flattened in the first unit passes through a similar process in the second unit, the creasing, however, taking place along a parallel line. The same process is carried out in a third unit, and in the following units which may be provided, the usual number of units thus proion vided for giving to the sheet the required number of crimps being flve, but it will be understood that more or fewer may be provided as desired. The entire crimping op eration may be performed on a single unit, in which case the delivery table is at the rear end of that unit, and the sheet of paper after passing through once will have a line of crimp formed thereon, and in order to produce additional lines the paper will be passed through the unit of the machine as often as the number of lines required will demand, and the guide 10 will be appropriately adjusted to assure the desired location of the lines.

Thus *far I have described the operation with particular reference to the formation of the crease and the flattening thereof, and

I shall now describe in detail the additional I wheels, 40

I cially in Figs. 3 and 3.

' 20 must be preserved features of the machine which contribute to the result above mentioned. The lower feed rolls, forming rolls and flattening rolls are mounted at their ends in fixed journals and are not therefore intended to have a sliding or adjustable movement. The upper feed rolls and flattening rolls, however, are intended to bear upon the paper with their weight and to be adjustable vertically to accommodate the machine to paper of varying thickness and quality. Consequently, sliding journals as shown at 56, 57 for the ends of roller 17 are provided, these journals being mounted in the side frame 58 of the machine in such manner that they are capable of a vertical sliding movement. If the paper fed into the machine is thin the toproll will occupy approximately the lowest limit of adj ustment, whereas if the paper fed into the machine be thicker the position of the top roll will be accordingly raised automatically. By the use of this construcupper rolls constantly. bears upon the paper, and as these rolls ro- I tion the weight of the tate the consequent gripping action between the rolls will carry the paper without slipping in the direction of the movement.

The fold imparted to the paper in passing through the first set of forming rolls 19 and as the sheet advances to the second set of forming rolls, and to accomplish this end I mount on the side frame of the machine a member 59 by means of the supports 60, 61. Projecting upwardly from member 59 between each set of the series of forming rolls, and between the last set of forming rolls and the creasing are standards 62, 62*, 63, 63 64, 64;, and 65, 65 on which are mounted guide members 66, 67, 68, 69, 70, 71, 72 and 73. As the fold issues from the forming rolls 19 and 20 it is received between the guides 66,

67. (see Fig. 2), and it is maintained in proper position between said guides by means of a vertical guide 74 shown espe- Guide 74 is mounted upon the lower end of the rod 75 which is in turn hung from a bar 76, which in turn is mounted upon the side frame of the machine at 77 and 78. A series of four of said vertical guides isprovided for the front portion of the machine appearing at 74, 79, 80 and 81. The function of this guide is made clear in Fig. 3 where the end view is presented, and referring to that figure especially the guide is shown penetrating into the fold, the fold being held laterally between the guide members 66 and 67. Therethe second set of forming rolls the fold is received therein practically as it comes from the first set of rolls. This operation is continned until the creasing wheelsare reached,

maaose the distance between the guide members gradually narrowing-to correspond with the groove in the preceding set of rolls, and the depth to which the vertical ide extends being also determined by t e de th of the groove in the preceding set of ro Is. The last set of guide members 72 and 73 with their vertical guide 81 maintain the form of the fold until the creasing wheels 37 and 38 are reached, wherein the fold is given a sharp creased form.

The creasing wheels 37 cially shown in Fig. 6 in which it appears that wheel 37 is mounted at the upper end of a shaft 83,. upon which shaft is carried the gear 84, and at the lower end of said shaft 83 is a bevel gear 85 adapted to mesh with bevel gear 86 on horizontal shaft 87 journaled at one end at 88 and at its other end at 89 in the transverse frame member 90 connecting the side frame members 91 and 92. The shaft 87 carries at its 0 posite end bevel gear 93 adapted to mes with bevel gear 94 carried on the longitudinal shaft 95 supported in the bracket 96, said the means described the creasing wheel 37 is rotated, and through the gear 84 which is adapted to mesh with gear 97 mounted on shaft 98 which carries the creasing wheel 38, the latter is likewise rotated. The shaft 98 carrying the creasing wheel 38 is mounted in a sliding journal 99 carried by the casing 100. he rear part of the casing 100 is attached to the frame member 90 by means of the screws 101 and 102; member 99 is cut away as shown to take over the heads of the said screws. The sliding journal member 99 permits of lateral adjustment of the creasing wheel 38, which ad ustment is performed automatically as varying thickness of paper operated upon. This adjustment is effected through the lever 103 pivoted at 104 and carrying at its lower end the roller 105 adapted to bear against the end 99 of the sliding journal member 99. Rod 106 passes through the standard 107 and carries between said arm and the end of the rod a spring 108 held on therod by means of the nut 109. The tension of the spring is regulated by means of the nut 109 as desired for any particular operation, and if there should be variations in the thickness of this paper the creasing wheel 38 will through the adjusting means described adapt itself so as not to crease the paper too sharply and injure it.

The second series of forming rolls, which produce an upwardly projecting fold in the paper, is mounted as above described, and in this-portion of the machine the vertical guides 110, 111, 112 are mounted below the forming rolls on the bar 113, which in turn is mounted upon the frame member 4 of the required by the i intense creasing wheels 49 and 50 are shown clearly in Fig. 7 in which it appears that wheel 49 is carried on shaft 119 journaled in the frame 120. Shaft 119 carries the gear Wheel 121, and in its upper end the bevel gear 122, adapted to mesh with bevel gear 123 can ried on the transverse shaft 124 journaled.

in the frame of the machine at 125 and 126. At one end said shaft 124 carries the gear 127 which is adapted to mesh with gear 127 actuated by gear 187 driven intermediately as hereinafter stated from the transverse shaft 128 which carries bevel gear 129 adapted to mesh with the bevel gear 130 mounted on the longitudinal shaft 95 supported by the bracket 131, said shaft 95 being driven from an appropriate source of power, as mentioned above. Creasing Wheel 59 is mounted on the shaft 132 which carries at its end the gear 133 adapted to mesh with gear 121 by which said creasing Wheel 50 is rotated. Shaft 132 is journaled in the sliding member 134 mounted slidably in casing 135 in the manner identical with that described above for the mounting of the creasing wheel 38. The sliding journal member 134 is adapted to be automaticallyactuated by the lever 136 mounted on pivot 137 and carrying roller 138 in engagement with the end 134 of journal member 134. The rod 139 mounted at the upper end of lever 136c'arries the spring 140 which is limited by the small plate member 41 and the nut 142, the latter being the means whereby said,

spring is te'nsioned. The creasing wheel being adjusted by this means for the kind of paper to be operated upon is thus automatically adjustable for-varying thicknesses of said paper, and consequently the degree of the creasing imparted to the fold is properly regulated.

llhe flattening form appears in detail in Figs. 9 and 10, in which the plate 40 is mounted on the frame of the unit at 40 and secured in place by the bracket 40 flange 40 is formed along one edge of plate 40, and receives the crease over the curving end 46 whereby the crease is opened as it travels along the curved flange. Plate 4O is mounted on the frame of the machine between feed rolls 40*, 40 and flattening rolls 41, 42, above the flange 40, to retain the sheet of paper in engagement with the flange 40 until the flattening rolls 41, 42 are reached, where the. opened crease is pressed out completely and the sheet is left comparatively fiat, to enter the portion of the machine wherein the creasing occurs in the opposite direction.

In some cases a creasing in both directions may not be desired, and in such case the operation may be stopped at this point, and the sheet removed and run through again to the same point to form a parallel creased line. lhe machine is intended for such use as may be desired, creasing in one or both directions, and using one or more units, as may be preferred. All work necessary to produce a sheet having a plurality of doubly crimped lines thereon may obviously be carried on one unit, but for each line or crimp the sheet will be taken on a separatetrip through the machine. And if crimping on y in one direction is required, the sheet will be retracted after the flattening rolls have operated.

Flattening form 51 need not be described, since its construction and function are the same as that of so, except that it operates upon an upward protecting crease.

The rotation of the feedrolls, the forming rolls, and the flattening rolls of the machine is effected in the. following manner: Along one side, in this instance the left side of the unit, is a horizontal shaft, which is above designated 95, journaled in the side frame of the machine at 143 in bracket 144, and at 145 in the bracket 146, and at the free end 147 said shaft is here shown broken, but at this point connection with the source of power may be provided or the shaft may be prolonged to drive subsequent units of the machine as desired. Said shaft 95 carries the bevel gears 94, 130 which are adapted respectively to mesh With bevel gears 93, 129', carried at the ends of the transverse shafts respectively 87 and 128. On the transverse shaft 87 is mounted gear 148 adapted to mesh with gear 149 mounted on the stub shaft 150 carried by the side frame 91 of the machine. Said gear 149 is adapted to mesh with gear 151 likewise mounted on stub shaft 152 carried by the side frame of the machine, and said gear 151 is adapted to mesh with gear 153 carried at the left end of the lower forming roll 30 of the last "set on the front portion of the machine. gear 153 meshes with gear 154 carried on the upper forming roll29 ofthe said last set. Gear 153 likewise is adapted to mesh with gear 155 which meshes with gear 156 carried on the lower forming roll 28 of the third set of forming rolls on the forward end of the machine, and gear 156 meshes with gear 157 carried on the upper roll 27 of said set. Likewise gear 156 drives gear 158 which in turn drives gears 159 and 160 on the second set of forming rolls, 25, 26. Gear 159 likewise drives gear 161 which in turn drives gears 162 and 163 on the first set of forming rolls, 19, 20. Gear 162 like wise drives gear 164 which in turn drive Said gears 165 and 166 on the w.

39 and ear 167 also drives gear 169 which.

in turn rives gears 170 and 171 carried on the set of feed rolls 40, 40 and gear 170 likewise drives gear 172 which in turn drives gears 173, 174, mounted on the flattening rolls 41, 42. The gearing construction just described imparts a rotary movement to the parts mentioned, and the manner of imparting movement to the creasing rolls 37 and 38 has been described above.

0n shaft 128 is mounted gear 175 which is adapted to mesh with gear 176 mounted on thestub shaft 177 in the side frame of the machine. Gear 176 meshes with gear 178 which drives gears 179 and 180 mounted at the ends of the last set of forming rolls 47 and 48. Gear 179 drives gear 181 which in turn drives gears 182 and 183 carried on the forming rolls 45 and 46, and gear 182 drives gear 183 which in turn drives gears 184, 185 carried on forming rolls 43 and 44. Gear 178 likewise meshes with gear 186 which drives gear 187, said two latter ears being mounted at the ends of feed rolls 49 and 49. Gear 186 likewise meshes with gear 188 which drives gears 189'and 190 mounted on the feed rolls 52, 53, and gear 189 drives gear 191 which in turn drives gears 192 and 'l93 mounted at the ends of the flattening rolls 54, 55. In this manner, the rotary parts ofthe upper creasing member of the unit are actuated. The mechanism for driving the upper creasing wheels has been described above. 1

The transverse rollers hithertodescribed are provided at desirable intervals with groovesshown at 194 and 195, and through these grooves is passed the string 196 which is endless and is carried by the top rollers from front to rear of the unit. A similar string or wire may be provided on the lower rolls. These strings aid in carrying and maintaining the adjustment of the paper, especially by preventing buckling between the successive sets of rolls.
