SHEET WINDING AN D WRAPPING MACHINE Application filed May 9,

This invention relates to machines for winding lengths of sheet material into rolls and wrapping them with paper and then sealing, and has been more particularly de signed for handling roofing -;nater1al such asis formed of felt impregnated witlras' phalt or similar material, although 1t-1s not restricted to such use.

Roofing materialof this nature is made in various thicknesses and widths, and, as it is desirable to roll in each package material suilicient to cover definite areas of a roof, this invention provides means by which the roofing is automatically measured 5 01? in such various lengths as may be desired. Means is also provided for slitting the roofing into stri s of the widths desired. It is also desirable to measure off the wrapping paper to conform .to the various sizes of completed roll, and mechanism for accomplishing this function has also been provided. The material should be wound under the proper tension, it being evident that, as the roll, increases in size, the rate of rotation thereof for a given linear speed of the material decreases.-

Winding mechanism, conforming to these requirements, has been provided by this in rention.

fingers be which are rotated to wind the same, together with means for removing these fingers when the roll is completed so that it These fingers are so constructed and actuated that, before a new roll is to be made, they are presented in correct position to receive the roofing sheet. Sheet-guiding devices, which direct the sheet between the fingers but which do not interfere with the subsequent winding, are also a part of this invention.

in order to ensure proper wrapping of the roll, one end of a sheet of wrapping paper is wound into the roll just prior to its completion, the other end of the paper having glue applied thereto so that, by continuing the Winding operation after the completion of the roll of roofing, the wrapping thereof and fastening of the wrap ping paper is effected.

For a more complete understanding of this invention, together with other objects and advantageous details and combinations 1921. Serial No. 467,799.

Referring to these drawings,1 and 2 indicate a pair of side frame portions carrying the mechanism for handling the roofing material, and 3 and 4 indicate side frame portions superposed on the portions 1 and 2 and carrying the wrapping paper holding and feeding mechanisms.

Roll winding mecizwnism.-As shown more particularly in Figures 1, 2 and 3, positioned adjacent the frame portions 1 and 2 are a series of pedestal blocks 5, 6 and 7. The pedestal 5 is preferably'in fixed relation to the frame portion 1, but the pedestals Hand 2 are preferably adjustably mounted relative to the machine toward and from the frame portion 2 to adjust for different widths of rolls. As the exact method of mounting these pedestals for such adjustments is immaterial to this invention, no detail showing thereof has been made.

Referring to Figure 9, pedestal 5 carries at its upper end a bearing 8 within which is journaled a hollow sleeve 9. Fixed to the sleeve 9 at one side of the bearing 8 is a second sleeve 10 terminating at its end opposite to the bearing 8 is a flange 11. A collar 12, fixed to thesleeve 9 adjacent the opposite face of the bearing 8, holds the sleeve 9 from axial movement in this hearing. Journaled on the sleeve 10 adjacent the flange 11 is a gear 13 which is pressed against the flange 11 by means of a collar 14: surrounding the sleeve and uiged axially of this sleeve by means of a series of springs shown at 15 surrounding guide pins 16 made fast in a ring 17. Ring 17 is held in position by a split collar 18 internally threaded to engage the threaded extremity of the sleeve 10. A tightening; bolt 19 may be used to draw tother the split ends of the rin g 18 to hold he same in adjusted position. If desired, "s may be interposed between the the gear 13 and the gear 13 a rivets as 20 being shown e washers are made fast to the By this construction, the .u irictional driving relation to vs 10 which in turn is keyed by the so the sleeve 9. The frame portion 1 bearing 22 in alinement with the bear- 8 receive the sleeve 9 adjacent the inwardly of the bearing 22, a collar 23 is made fast to the sleeve 9 and adjacent thereto is made fast a spool flange 2 1 having a cover plate 24'. Within the sleeve 9 is carried a block 25 into the end of which are screwed a plurality of winding fingers 26, preferably four being; employed which projithrough perforations in cover plate oe inner end of the block 25 has fact there's the end of a shaft '27 this shaft oeconcentric with the sleeve 9 and projecting outwardly therethrough. The pedestal 5 28 having at 'ts outer end a. vertical journal bearing 30, and adjacent thereto a horizon-- tal guideway for the reception of a hollow bar 31. his rack bar projects within .eeve 9 the shaft 27 passes theren and is free to rotate therein. This is prevented from axial movement relae to t" he rack bar 31 by means of a collar s t thereto outwardly of the rack bar cam block 33 made fast by a pin 34: aft 27 at the other end of the rack bar.

may slide axially of the sleeve 9. but are prevented from rotation relative thereto by means of slot 9 in the sleeve within which rides a pin 27'. The rack bar 31. however, is held from rotation within its guideway.

Referring to Figure 10, it may be seen that cam block 33 has formed therein a series of notches 35 terminating at the end adjacent the rack bar in outwardly flaring portions 36, thus forming a series of pointed teeth 37 projecting toward the end of the rack bar. Fixed to the bracket 23 adjacent I the end of the sleeve 9 is an upstanding pin 38 having journaled thereon at its upper end roller 3.9,this roller being of a diameter to pass within the slots 35 of the cam block. this construction, on movement has "fixed on its outer end a bracket of the rack bar in a direction to retract the fingers 26, the cam block 33 impinges against the roller which enters between the teeth 37 and guides the shaft 27 in order to position the fingers 26 angularly so that the spaces therebetween may be properly presented to receive the sheet of rooting material, as will later be described.

In order to move the rack bar, a pinion 40, meshing with the teeth thereof is carried by a vertically extending shaft 41 journaled at its upper end in the hearing 30 and journaled at its lower end in a bearing 42 supported adjacent the foot of the pedestal 5. Within the bearing 42, shaft 41 carries a pinion 43 which meshes with a rack bar 44: projecting toward the center of the machine. The actuating mechanism for this rack bar 4 will be described later.

Pedestals 6 and 7 carry a mechanism in all respects similar to that just described supported by frame member 1 and the pedestal 5 except that it is reversed end for end so that the fingers 26 for supporting the roll extend in the opposite direction. This construction is shown in elevation in Figure 3.

Roofing feeding and mittingmechamsm. Referring now to Figures 1, 2 and 4, the frame member 1 at its forward end has an angular depression shown at and adja- 9 cent the upper end thereof the lower half of a shaft hearing as at- 51. The upper half 52 of this hearing is formed as a. bracket member having at its upper end a vertical slotin which is slidab-ly mounted a bearing, 100 block 53. This block has journaled therein a shaft 54 and a spring bears against the upper face of the block 53 and against the under face of aretaining member 56. The shaft 54 is journaled in a similar manner in 105 a bracket carried by the frame member 2 and has fixed thereon a pressure roll 57. This pressure roll is urged by the springs 55 into contact with the periphery of ameasuring roll carried by a shaft 61 journaled no in the bearing blocks 51 and 52. The bearing block 52 has pivoted thereto at 62 a bracket 63,. Near the apex of the angular recess 50. this bearing bracket 63 has journale'd a shaft 61 which carries an idle tenl sion roller 65,'it being understood that a similar bracket 63 is carried by the frame portion 2 and carries similar bearing portions forthe various parts On the horizoutal lower face of the bracket 63 is journaled a shaft 66 which may have fixed thereon one or more circular slitting knives, as shown at 67 Cooperating with these knives in shearing relation thereto are similar knives 68 carried by a shaft 69 journaled in the frame portions 1 and 2. The outer end of the bracket 63 has a pair of pedestal jaws for the slidable reception of a bearing block 70 urged downwardly therein by a. spring 71 hearing between its upper face and a pedestal closing block 72. This shaft carries an idler roll 73. Fixed outwardly of this idler roll is a guide plate 74. The outer face of the bracket 63 bears against the up per face of the frame portion 1 at and an eye-bolt 76 pivotally mounted on the portion 1 on a pin 77, (see Figure carries a nut 78 on its upper end which may be moved into engaging relation to the bracket 68. A similar construction is employed in connection with the frame 2 and allows the brackets 63 to be swung upwardly so that access may be had to the various rolls and the slitting knives for ease in threading the material in the machine.

The strip of roofing, shown at A, passes downwardly between the guide plate 7-1 and the idler 73, and from thence past the slitting knives 67 and 68 around the idler roll 65, around the measuring roll 60, beneath 'the pressure roll 57, across the upper surface of a table 80 and beneath a guide plate 81, and across the upper face of a shear.

block 82 to a supporting table 83 toward the winding mechanism. Pivoted at 84, between the frame portions 1 and 2, is a sheet guide 86, which may, if desired, be forined of a series of spaced links carrying at their outer ends a roller 87.- The table 86 has a rearwardly projecting lug S8 to which is attached the end of a coiled spring 80 made fast at 90, (see Figure 4,) to the machine frame. This spring normally holds the sheet guide 86 in the position shown in full lines in Figure 4 where-it furnishes a continuation for the table 83 and over which the sheet A is guided between the fingers 26. As the material is wound, however, the roller 87 bears thereon and is moved downwardly, as shown in dotted lines, carrying the outer end of the table. to avoid interference with the winding of the roll, this action being effected against the tension of the spring 89. This construction not only serves to present the sheet A in position to pass between the fingers 26, but exerts pre sureon the outside of the roll as it is formed, aiding in the closewinding thereof. This action is further aided by means of a pressure roll 91 carried by apair of arms 92 (see Figures 3 and 4) which are fixed to a shaft 93 journaled above the fingers 26 and to which is fixed an arm 94: normally drawn inwardly by a. spring 95 engaging over a hook 96 to the frame 1.

Cooperating with the shear block 82 is a cutting blade 100 fixed to a slide 101 guided in vertical slideways in the frame portions 1 and 2. The upper end'of these slideways are closed by retaining plates 102 through which project vertically-extending posts 103 fixed at their lower ends in the slide 101 and having a pair of check nuts 101 threaded on their upper ends. A cushioning spring 105 surrounds each post 103 and cushions the blow as the slide 101 descends, this descent being accomplished by gravity, as will later be explained.

For the purpose of actuating the mechanism so far described, the following driving connections have been provided. Referring to Figures 1 and 2, at is positioned a hearing bracket which carries journaled therein a shaft 111, having afiixed thereto a driving belt pulley 112. Also fixed to the shaft 111 is a gear indicated at 113, meshing with a gear 114 fixed to the main drive shaft 115. Above shaft 115 are three shafts arranged in a horizontal plane atillG, 117, 118, which will be referred to hereafter as the main cam shaft. the secondary cam shaft, and the clutch shaft respectively.

Referring more particularly to Figures 1 and 8, the frame portion 2 carries a bracket 110 having journal bearings for a shaft which has fixed thereon between the bearings a worm 121. 'This worm meshes with a worm gear journaled on the secondary cam shaft 117. At one end, shaft 120 has a bevel gear 123 which meshes witha bevel gear 124 fixed to the drive shaft 115. Outwardly of the frainc2, a gear 125 is fixed to the clutch shaft 118, and meshing therewith is a. pinion 126 (see Figure 1) carried by the drive shaft 115. It will thus be apparent that shaft 118 will be driven continuously by the drive shaft 115, and that shaft 117 may be driven through the worm 121 and the worm gear thereon when the worm gear-is in driving relation thereto, as will later be explained.

The shaft 116 is driven from the clutch shaft through change gears as follows. Shaft 116 projects outwardly of the frame portion 1 and carries on its end a gear 127 (Figures 1 and 2) which meshes with a gear 128 carried by an arm 12$) pivoted or a shaft 130 journaled in the frame portioi 1. The arm 129 has an arcuate slot 131 concentric with the pivotal connection 130. A stud 132 passes through this slot and is fixed to the frame 1, and threaded on its outer end is a nut 133 which may be screwed down against the arm 120 to hold it in position. This construction permits the use of various sizes of gears 127 by which the speed of the shaft 116 may be varied, the arm 129 being adjusted to bring the gear 128 in mesh with the gear 127 whatever size of gear may be used. The shaft 130 carries a gear 135 meshing with the gear 128. As shown in dotted lines in Figures 2 and 4-, the shaft 130 also carries a spiral gear 136 meshing with a spiral gear 187 which is carried by a vertical shaft having at its upper end a bevel gear 138. This gear meshes with a bevel pinion 139 on the shaft 01 which carries the measuring roll (30. A large sprocket wheel 140 is also carried by the shaft 61 and over this sprocket is passed a drive chain 141 which engages a sprocket wheel 149; journalecl on the shaft 118. The shaft 61 also carries a sprocket wheel 1 13 over which passes asprocket chain 14% engaging a sprocket wheel 145 fixed to the shaft 9 for rotating the splitting knives 68. The winding mechanisms are actuated from the clutch shaft 118 as' follows: Arranged beneath the she 118 is a vertically-extending shaft 146 (see Figures l and 8) which carries at its ier end a oevel gear 117 meshing with a r of bevel gears 148 and 149 (see Figure et on the shaft 118. The lower it 1413 carries a bevel gear 150 a similar gear 151 fixed to a shaft carries a pinion 1:33 in i 1.54 and 155 ositioned above and er bar 1- being fixed to ioned, by which mech- 2-6 are moved axially plaincd.

At opposite ends of this shaft are carried the snail cams 184 which are adapted to impinge against posts as 185 fixed to the knife slide 101. In order to ensure a free movement of the slide 101, opposite ends thereof are provided with series of rack teeth 186 which mesh with a pair of spur gears, 187 carried at opposite ends of an equalizing shaft 188 journaled at its opposite ends in the frame portions 1 and 2.

The mechanism thus described is timed to obtain the following sequence of operations, as will be more fully described later. The feed roll is turned to feed a length of roofing over the tables and 83 and between the fingers 26 as shown in Figure 1. When the strip is in proper position between these winding the roofing in a roll, preferably one roll being formed on each of the op posed series of fingers, the roofing having been split by the knives 67 and 68 on its passage thereto. 1V hen suflicient roofing has been wound on these lingers, in accordance with the setting of the change gears above mentioned, the rotation of the measuring roll 60 and the winding fingers 26 is stopped, and further action of the machine causes the snail cams to allow the knife 100 to drop, thus severing the strips. This having been accomplished, rotation of the fingers again started to complete the winding of the roll. When this has been completed, the rotation of the fingers is stopped and they are then retracted axially from the rolls by the'action of the clutch mechanism '17 3 through which motion is imparted to the chine causes the roll fingers to return to their former position and stop, while the measuring roll 60 is again actuated to feed the material in position between these fingers for a repetition of the same cycle of operations.

Wrapping paper mecimnism.-5ust prior to the completion of the winding operation a strip of wrapping paper is fed to the roll by mechanism which will now be described. Referring more particularly to Figures 1, 8, 4, 5 and 6, the frame portions 3 and i carry, above the measuring roll, in sockets, a shaft 200 for supporting the wrapping paper roll or rolls. The paper is led up from the inner side of these rolls, over a feed roll 20% positioned near the upper part of the machine, and as shown more articularly in Figure 4 down through a guideway 202 having a shear blade 203 at its lower ed e, past a cooperating shear blade 204 carried by the upper end of a rocking brackst 205, a clamping plate 206 being positioned opposite the bracket 205 and cooperating The paper then passes over an abutment roll 207 arranged totake the pressure from a glue-applying roll 203, thence down in.

contact with a feeding belt 209 passing over I an upper pulley 210 and a lower pulley 211,

a series of guide fingers 212 (see Figures 3, 4 and 6), being positioned in parallel re lat-ion to the feed belt to hold the paper in contact with the latter. The feed belt and the fingers 212 act as a chute to guide the lower edge of the paper closely toward the rollof roofing. In order to impart a positive feed for the paper the feed roll 201 is driven through a pair of meshing gears 213, 214 (see Figures f and 6) carried adjacent the frame member 2, gear 214 being carried on a shaft adjustably mounted in slots 215 in the frame portions 3 and 4. This allows gear-S214 of different sizes to be suhstitutedns desired in order to determine the amount of paper to be fed. This gear 214 is driven from a s rocket wheel 216 carried by the same sha t by a chain 217 which passes about a sprocket wheel 217 'journaled on a shaft 218. A second sprocket 219 fixed to this same shaft carries a chain 220 which passes downwardly around a .sprocketwvheel 223 carried by the main cam shaft 116-. As this shaft, as before described, is driven through a system of change gears, it is evident that the paper feed willbe subjected not onlyto the adjustment derived therefrom in conformity to the feed'of the roofing, but is also subject to further modification by the change gear 214. r

In order to properly feed the paper as is passes over the feed roll 201, it is held pressed thereagainst by means of a pressure roll 224 carried on a shaft 225 journaled in a pair of bell-crank arms 226 (see Figure 6)., these bell-crank arms having out wardly extending portions 227 to which may be attached weights as 228 (see Figures 1, 4 and 5).

The wrapping paper is cut into proper lengths by the knife 204 which is carried by the rocking bracket 205 fixed to a shaft 229 projecting outwardly of the frame 3 and having fixed at its outer end an arm 230. To the end of this arm is attached by a bolt and slot connection-at 231 the upper end of. a link 232 which is pivoted at 233 to the knife slide 101, it being thus evident that with each descent of the knife slide to out the roofing, knife 204 will also be actuated to cut off a section of the wrapping paper. The pressure plate 206 cooperating with the knife bracket 205 is normal 1y held in contact with the paper by means of a spring 234 fixed at one end to the frame' and engaging over an arm 235 fixed to a rock shaft 236 which carries this plate.

The glueapplying 1:011 208 is-carried by a pair of arms 237 fixed to a rock shaft 238 which carries at one end an arm 239 having a cam roll at its outer end in cooperative relation to a cam 240. This cam is carried by a shaft 241 extending across the machine, and outwardly of the frame portion 4 this shaft carries a sprocket 242 over which passes a chain 243 which leads downwardly to a similar sprocket wheel 244 carried on the secondary cam shaft 117. The cam 240 7b is so formed that the rotation thereof causes the glue-applying roll 208 to be moved at times away from the paper and into c0ntact with a. glue-applying roll 245 dipping down below the surface of gluecontained in a receptacle 246. The roll 245 is carried by a shaft 247 extending outwardly from the receptacle and through a pair of bearings 248 (see Figure 0) at either end "thereof. Outwardly of the bearing 248 adjacent the 8 frame portion '3, the shaft"247carries a sprocket wheel 249 overjwliicli passes a chain 250 which connects with a similar sn'ocket wheel 251 carried by'a shaft 252.

' utwardly of thev frame 3,sha ft 252 carries a belt wheel 253 whichmay .bedriven by a belt from any suitable source as a counter-shaft mounted above the machine, This shaft 252 alsocarries the feed belt roll 2'10. The'abutment roll207 for the feed belt 3*? is similarly carried on a shaft '2 54 which projects outwardly-from the frame 4 and has fixed at its outer end abelt ungyesa; which may also be drivenfrom the over head counter-shaft. f I f 10,

This mechanism is so timed. as to 'feeda" length of paper from theroll carried by shaft 200 in the path, as above described," during the feed of the roofing material As the roofing material is cut, the length of 0 paper is out also and the upper end thereof is held between the camplate 238 and the? rocking bracket 205. Thereuponthe glueapplying roll 208 is moved into" contactwith the paper near its upper end and the 9 ring to Figure 7, the main cam shaft 116 '125 carrying the cam 179 is in position to hold the clutch 178 in engagement with the worm 122, so that the secondary cam shaft 117 is connected for driving. The cam 174 on this shaft is in such a position that the clutch .the mai on acts to again throw clutch 178 into en- 170 is in engagement with the sprocket wheel 142 so that the measuring roll is connected in driving relation with the clutch shaft 118, as above described. The clutches 171 and 172 are out of engagement with the sprockets 160 and 161 and the clutch mechanism 173 is in mid position out of engagement with both bevel gears 148 and 149, so that the winding mechanism is ldle. On actuation of the machine, the measuring roll is then driven from the clutch shaft 118 and the paper feed is driven therefrom toward the fingers 26. The roofing material then feeds in between the pairs of fingers 26 into the position shown in Figure 4, whereupon the cam 175 on the secondary camshaft actuates the clutch 171 to rotate the fingers 26, as above described, in a counter clockwise direction as seen in Figure 4, thus starting to wind up the roofing. Just after-the clutch 171 is thrown in, cam 179 on the main cam shaft acts to throw the clutch 178 out of engagement with the 'worm 122, thus stopping the rotation of the secondary cam shaft, whereupon the cams 174, 175, 176 and 17 7 are idle. This condition of the mechanism continues until the main cam shaft 116 has made nearly a complete revolution, the time thereof depending on the size of the change gears used. Toward the completion -of this rotation of cam shaft 116, the earn 179 theregagement with .the worm 122, thus again starting the rotation of the secondary cam shaft 117. The cam 174 then acts to throw clutch 170 out of engagement with thesprocket 142,-which discontinues the rotation of the measuring roll, it having rotated sulficiently to feed out the required length of roofing for the roll and paper for wrapping it. At the same time that clutch l70is thrown out, clutch 171 is also dis connected from the sprocket 160 to discontinue the rotation of the winding fingers 26. At this pointin the cycle of operations, the snailcams driven from the' secondary cam shaft 117 allow the knife 100 to descend by gravity to sever the roofing material against the edge 82, and at the same time the wrapping paper knife 204 is actuated to sever the strip of wrapping paper. The rotation of the secondary cam shaft 117 also actuates the glue roll, as before described, to apply glue to theupper portion of the wrapping paper. As soon as this cutting of the strips and gluing of thewrapping paper has been effected, the clutch 172 is thrown'into engagement with the sprocket 161, by the action of the cam 176 on the secondary cam shaft, to start the rotation of the winding fingers 26. The lower end of the wrapping paper, passed downwardly through the machine by means of the belt 209, is presented to the roll by the time the second rotation shaft then disengages the clutch 172 by the I I action of the cam 176, and rotation of the winding fingers ceases. The cam 177 on the secondary cam shaft now acts to throw the clutch mechanism 173 into driving engagement with the gear 148, which acts through the horizontal bevel gear 147 to actuate the mechanism for retracting the winding fingers 26. The outer end of the roll being held by the spool flange 24, this motion of the fingers pulls them from within the roll, which thereupon falls from its position and may be received by any suitable conveyor, by which it may be removed from the machine. In case the roofing is split in two by the knives 67 and 68, it is evident that a pair of rolls are wound and wrapped to throw the clutch 170 into engagement with the sprocket 142 to start the measuring roll for a subsequent cycle of operations.

Having thus described an embodiment of this invention, it should be evident to those skilled in the art that many modifications and changes might be made therein without departing from its spirit or scope as defined by the appended claims.
