' 26 Claims. (Cl. 131-20) This invention relates to the machine manufacture of cigars and more particularly to reinforcing the head end of cigars.
With both naturaland processed leaf, it is frequently r ecessary or de sirable to provide a reinforcing strip at the head end of the cigar to guard the cigar against the teeth and saliva of the smoker. The practice has developed recently of applying a reinforcing strip to the 'head end of the cigar binder during manufacture so that the strip will be enwrapped about the head end of the cigar. Such reinforcing strips may be made of various materials both smokable and non-smokable in and of themselves. As for example, cellophane, Mylar, tinfoil and processed tobacco material are among suitable materials.
It is an object of this invention to provide anew method of so constructinga reinforced cigar.
It is also an object of this invention to provide a device which may accomplish the novel method as well as other methods that may be preferred by some.
More particularly, it is an object of the invention to provide a device that may deliver such a reinforcing strip to the outside of a cigar binder so that upon rolling the reinforced strip will be on the outside of the cigar bunch.
At the same time, it is an objectof the invention that the reinforcing strip, if desired, can be delivered to the inside of the binder where upon rolling it will be concealed by the binder.
It is an object of theinvention to provide a method for securing such a strip to the outside of the binder so that its proper position may be maintained during the rolling I operation and further that the reinforcing strip itself may secure the cigar binder about the cigar charge.
It is a further object of the invention to provide a device .for delivering a reinforcing strip from an endless source, severing predetermined portions from said source and positioning such portions on the rolling table in a suitable place, and providing adhesive means to retain it in place on the binder. It is a further object of the invention to provide a method and device for delivering such a strip of reinforcing material readily adaptable without the modelling of parts to various shapes and sizes of cigars.
A further object of the invention is to provide a method and a device as set forth above readily attachable to conventional cigar machines and operable therefrom and in timed relation thereto.
It is a particular object of the invention to devise a means for severing a predetermined length of reinforcing strip and applying a daub of adhesive to one side of said strip so that the strip may then be adhesively secured to the outside of a binder and thereby maintained in proper relative position during the rolling operation.

With reference to the drawings, the reinforcing strip web W is pulled from a reel R by means of a pair of intermittently driven feed rollers 10 and12 which advance the leading end of the web onto an intermittently oscillating conveyor and applicator platform 14. The upper feed roller 10 is rotatably mounted on a shaft 16 provided with the customary eccentric end extension, by means of which shaft 16 is supported in suitable downwardly spring-urged bearing blocks 18 slidably mounted in vertical slots in a bearing bracket 20. One of the eccentric ends of the upper feed roller shaft 16 carries a trip finger 22 (FIGS. 2 and 3) by means of which the roller carrying portion of shaft 16, and consequently the upper feed roller 10, may be raised out of contact with the lower feed roller 12 to permit threading of the web before starting the machine. Bearing bracket is secured to a supporting plate 24 which, by means of suitable slot 26 (FIG. 4) and screws 28, is adjustably mounted on a suitable bracket 30 and a supporting bar 32. The bracket 30 is mounted on a suitable lug 34 which is integral with and projects from a r 7' gearing housing 36 which is part of the cigar machine.
The supporting bar 32 is secured to the top end of a pair of suitable uprights 38 rigidly mounted on the bed plate 40 of the machine.
The reel R is supported by means of two conical flanges 42 and 44. Flange 42 is provided with a sleeve 46 (FIG.
,1) rotatably supported on a stationary stud shaft 48 sefree end of a threaded stud 58 held in a threaded bore in. bracket extension 50. Stud 58 is equipped with a suitable knob 60 provided for the purpose of turning said stud to effect a lateral adjustment of the conical flanges 42 and 44 and therewith a lateral adjustment of the reel R and consequently of the web W.
To prevent overrunning of the reel R during the intermittent feed motion applied upon the web W, the conical flange 42 is provided with an annular groove 62 which engages with a brake band 64, one end of which is an- 3 chored to the free end of a stud 66, while the other end is secured to a stud 68. Stud 66 is slidably held in a suitable bore of bearing bracket 51) while stud 68 is slidabiy supported in a suitable bore in the free end of a short arm of a bell crank lever 70 which is loosely mounted on a stud shaft 72 held by hearing bracket 50. To the free end of the long arm of the bell crank lever '70, by means of a pin 73, is pivotally attached one end of a link 74, while the other end of said link is provided with a slot 76 which engages with a pin 78 projecting from and held by an arm 80 mounted on a horizontal shaft 32 supported by suitable bearings of bracket 20. The free end of arm 80 carries a stud shaft 84 which rotatably supports a web control roller 86.
To assure smooth operation and prevent any jerky motion being transmitted to the brake linkage system during the intermittent feed action, a roller balance spring 88 is provided. The upper end of this spring in anchored to the pin 73 while the lower end of the spring is attached to the pin 78 on the roller carrying arm 86. It is evident that in case of a breakage of web W, the weight of the roller 86 forces said linkage downward and tightens the brake band 64 in the groove 62 of the conical flange 42, while during normal feeding operation, when the roller is partly supportedby the web W, the brake band receives only suflicient tension to effect a desired drag on the reel R. A suitable micro switch (not shown) may also be provided to effect a stoppage of the entire machine in case the web W breaks or runs out during operation.
As mentioned heretofore, the reinforcing strip W is fed and intermittently advanced by means of the upper and lower feed rollers and 12, respectively. The upper feed roller 10 is driven by means of a gear 90 (FIG. 1) which is loosely and rotatably supported by the upper feed roller shaft 16 and secured to the hub of said feed roller. Gear 91) meshes with a gear 92 mounted on the lower feed roll-er shaft 94 to which the lower feed roller 12 is secured. Shaft 94 is rotatably supported in bearings of bracket 20 and carries on one end a conventional onedirectional clutch 96 which, in turn, is connected to a gear 98 loosely mounted on the shaft 94. Gear 98 meshes with and is oscillated by a gear segment 100 (FIGS. 1, 2 and 3) pivotally supported by a stud shaft 102 held by a suitable bearing bracket 104 secured to the bottom side of the supporting plate 24. Integral with and extending from the hub of gear segment 100 is an arm 106 (FIGS. 1 and 2) which, by means of an adjustable rod 168 is connected to a crank pin 110 adjustably secured in a slot 112 of a cam 114 mounted on a cam shaft 116 driven from the main drive of the machine (not shown). By adjusting the crank pin 110 towards or away from the center of the cam, the length of the strip feed can be varied to any desired length. From the driving arrangement of the feed rollers described above, it is evident that although the gear segment 1% imparts oscillating motion to the gear 98, the one-directional clutch 96 permits only one-way intermittent motion to be transmitted to the feed roller drive shaft 94.
The leading end of the web W'is fed by the rollers 10 and 12 between an upper guide plate 117 and a lower web Supporting plate 118 onto the hollow transfer and applicator platform 14. Platform 14 by means of screws 12s (FIGS. 3 and 4) is adjustably secured to an enlongated slot 121 of a flange 122 which is integral with a hollow arm 124 loosely mounted on a hollow shaft 126. Shaft 126 isrotatably supported by bearing bracket 128 secured to the supporting plate 24. The bottom of the hollow platform 14 is provided with a slot 130 which registers with a hole 132 (FIG. 4) in the flange 122 of the hollow arm 124 thus providing air passage from arm 124 into platform 14. The hollow shaft 126 is also provided with two suitable cut-outs or ports 134 and 136 (FIG. 4). Port 134 connects the duct in hollow shaft 126 with the hollow arm 124 and platform 14 while port 136 conmeets the hollow shaft witha duct 138 Within the bearing 4 bracket 128. Bearing bracket duct 138 by means of a suitable tube 148 is connected to a properly timed valve 141 in a hollow suction chamber 143 which. is-connected by means of a hollow tube 145 to a source of suction, not shown. Valve 141 is connected through pin 147 to a bell crank, a portion 149 of one arm only is shown in FIG. 1. The be'llcr'ank is controlled by a cam, not shown, mounted onshaft 116, to apply suction to, and to disconnect suction from platform 14 at proper times. The duct within hollow shaft 126 is closed at both ends by means of suitable plugs 142. Thus suction may be applied to the holes 218 of platform 14 to retain the leading portion of web W after it is fed thereto and during subsequent movement of the platform with a severed strip S.
To one end of hollow shaft 126 is secured a forked arm 144 which carries on each fork an adjustable screw 146 and 148, respectively. Screw 148 contacts one side of a lug 1511 (FIG. 1A) which is integral with and projects from the hollow arm 124 while the other side of lug 150 is contacted by a spring 152 confined between lug 150 and one fork of arm 144 and adjustably held in place by means of aforementioned screw 146. The hollow shaft 126 is oscillated by means of a bevel gear 154 secured to it and meshing with a bevel gear 156 mounted on a horizontal shaft 158 rotatably supported by suitable bearings in bracket 20.- Shaft 158 is actuated by means of an arm 160 fastened thereto. The free end of arm 160 by means of an adjustable rod 162 is connected to another arm 164 (FIG. 2) loosely supported by a stud shaft 166 (FIGS. 1, 2 and 3) held by a bracket 168 mounted on bed plate 40. Thehub of arm 164 is provided with a cam lever 170 which at its free end carries a cam roller 172 engaging with the earn 114 on cam shaft 116. A tension spring 174 anchored to a post and attached to arm 164 assures a continuous contact of the cam roller 172 with cam 114 as illustrated in FIG. 2.
From the arrangement described above, it is selfevident that cam 114 through cam lever 1'70, arm 164, rod 162 and arm 160 imparts oscillating motion to shaft 158 which through bevel gears 156 and 154 transmits the same to the hollow shaft 126 and forked arm 144 which, in turn, as described above, engages yieldingly with platform carrying hollow arm 124.
To the horizontal shaft 158 is secured another arm 1'76 (FIGS. 2 and 3) to the free end of which is pivotally attached a suitably shaped link 178 (FIGS. 2, 3 and 6). Link 178 at its free end is provided with a slot 180 engaging witha pin 182 projecting from and held by one arm of a bellcrank lever 184 loosely supported by a stud shaft 185 mounted on a bracket 186 fastened to the supporting plate 24. The second arm of said bell crank lever 184 by means of a twisted link 188 is connected to the free end of a knife actuating arm 1% which is rotatably supported by a stud 192 mounted on the bracket. 20. The hub of the knife actuating arm 190 is provided with a flange 1% to which is secured a suitably shaped knife blade 1%. A tension spring 198 (FIG. 3) surrounding stud 192 and confined between the head of the latter and the front face of the hub of arm 190 is employed to keep the desired tension between the knife blade 196 and the front edge of the web supporting plate 118 which also serves as ledger plate during web cutting operation.
Carried by and projecting from the knife actuating arm 190 is a pin 2% which engages with the forked end of alever 262 (FIGS. 1, 3 and 5) mountedon ahorizontal shaft 264 rotatably supported by the bearing bracket 186.
To shaft 294 is also adjustably secured a paster actuating arm 206 to which is adjustably mounted a paster bar 2138 the free U-shaped end terminating in a suitably shaped paste applicator point 210 (FIG- 5). The U- shaped end of paster bar 288 is so formed as to reach into a suitable paste pot 212 held by a suitable bracket 214 secured to the supporting plate 24. The paste applicator point 210 is so located and shaped so as to permit it to enter an open slot 216 provided in the forward end of the strip conveyor platform 14 and apply a daub of paste to the underside of a reinforcing strip when the paster bar 208 is raised. During the cutting and daubing operation the hollow platform 14 is supplied with suction.
The operation of the reinforcing strip Web feed is as follows: A predetermined length of reinforcing web W is pulled from the reel R by means of the intermittently actuated feed rollers and 12 and the leading end of said web is advanced over the plate 118 onto the hollow strip transfer platform 14 which at this time dwells at the forward end and in alignment with the web supporting plate 118. During the time the web W is advanced onto platform 14 no suction is admitted to the platform, but as soon as a predetermined length of web is fed onto it, suction from a controlled source, through tube 140, duct 126, hollow shaft 138 and hollow arm 124, is admitted to the platform causing the web to be held firmly. While the platform 14 dwells during web receiving operation, the cam roller 172 is in contact with the smooth concentric portion 220 of the cam 114 (FIG. 2).
As soon as the predetermined length of web W is advanced on the platform 14, suction is delivered to the platform to hold the end of the web and immediately thereafter the cam roller contacts and rolls onto a high spot 222 of cam 114, causing, through arm 164, a slight downward motion of rod 162 and arm 160 and a slight clockwise rotation of shaft 158 and arm 176. Since, as mentioned heretofore, the free end of arm 176 is connected to one end of the slotted link 178, the latter is moved to the right, causing the end of an adjustable contact screw 224 (FIG. 6) carried by the link and projecting into the slot 180 to engage the pin 182 which projects into slot 180 and moves the same and consequently the bell crank lever 184 which holds the pin in a clockwise direction. A clockwise movement of the bell crank lever 184, of course, effects an upward movement of link 188 and knife actuating arm 190 and a downward movement of the knife blade 196 to sever a predetermined length of strip S from the web W with the strip S held through suction by the platform 14 as described above.
Since the pin 200 projecting from the upwardly moving knife actuating arm 190 engages with the forked end of lever 202, it also imparts upward movement to lever 202 which, in turn, through shaft 204 and arm 206, transmits upward movement to the paster bar 2198. The upward movement of the paster bar 208 causes the paster applicator point 219 to enter slot 216 of platform 14 to daub paste on the bottom side of the forward end of the strip S. Thus the paste applying, as well as the cutting operation, occurs simultaneously as the cam roller 172 rolls over the high spot 222 of cam 114.
It is evident that any motion imparted to the knife actuating arm 190 and pastor actuating arm 206 is transmitted through the shaft 158. Since shaft 158 carries the bevel gear 156 which meshes with bevel gear 154 on the hollow shaft 126 to which is secured the forked arm 144, counter-clockwise rotary motion is imparted to the forked arm 144. Since forked arm 144 engages with the lug 150 projecting from the platform carrying hollow arm 124, it follows that arm 124 would also be moved in a counter-clockwise direction. However, during strip delivery as well as during strip cutting and paste applying operations, an adjustable stop screw 226 carried by a suitable boss at the bottom portion of the hollow arm 124 is in engagement with a suitable lug 228 secured to supporting plate 24. Therefore, any counter-clockwise motion imparted to the forked arm 144 on hollow shaft 126, when platform 14 on hollow arm 124 is in strip receiving position, is taken up by the spring 152 by means of which the forked arm engages the upper side of lug 150 of hollow arm 124.
As soon as cam roller 172 rolls'oif the high spot 222 of cam 114, the knife blade 196 moves upward and the paster bar 208 moves downward again. During the continued downward movement of the cam roller onto lower portions of cam 114, shaft 158 is caused to turn in'a counter-clockwise direction which results in a clockwise movement of hollow shaft 126 and consequently of the hollow arm 124, until cam roller 172 reaches the lowest portion 230 of cam 114, at which point the platform carrying hollow arm has moved to a position indicated in dotted lines in FIG. 1 in which the strip carrying platform 14 contacts face down a rolling apron A of a conventional bunch rolling table T of the cigar bunch forming machine.
The rolling table T consists of a hollow chamber 232, whose top surface is provided with grooves 234 and the grooves communicate through holes 236 with chamber 232. Chamber 232 is connected through air duct 151 and valve 153 to hollow suction chamber 155 which in turn is connected by means of air duct 157 to a suitable source of suction (not shown). Chamber 155 is connected through valve 153 and flexible air hose 163 to binder transfer Z, shown in FIG. 8. The transfer Z, as is well known in the art, is employed to deliver cut binders from a source of supply to the rolling table T. Valve 153 is reciprocated through pin 159 and a bell crank, a portion 161 of one arm only of the bell crank being shown in'FIG. 2. The bell crank is actuated by a cam, not shown, mounted on shaft 116. As valve 153 is reciprocated, an aperture 165 is presented alternately in alignment with duct 151 and air hose 163 at proper times to transfer suction from the table T to the transfer Z. The rolling apron A, also well known in the art, lies flat over the top surface of the rolling table during strip and binder receiving operations. It is provided with suitably arranged holes 238 aligned with the grooves 234 of the rolling table T to apply suction to the underside of the strip and the binder placed on the rolling apron.
In the chamber 232 of the rolling table T, by means of screws 240, is adjustably secured an auxiliary suction chamber 242 mounted with its open top side against the bottom side of the top wall of the rolling table so that some of the holes 236 in grooves 234 are connected to said auxiliary chamber 242 instead of chamber 232. Chamber 242 by means of a suitable tube 244 is connected with a suitable source of suction which supplies suction to the chamber 242 at all times. Chamber 242 is located beneath the area where the strip S is delivered onto rolling apron A. Therefore, as soon as the strip carrying platform 14 contacts the top surface of the rolling apron -A as illustrated in dotted lines in FIG. 1, the suction supply to the hollow arm and platform 14 is shut off and the strip S is held through suction on apron A coming from the chamber 242. At this time, the knife blade 196 is in its upmost position while the paster bar 208 is in its lowermost position with its applicator point 210 submerged in paste pot 212. As soon as the strip S is deposited by the platform 14 onto the apron A, the hollow arm 124 swings upwardly due to the cam roller 172 rolling up the inclined portion 246 of cam 114. When roller 172 reaches the concentric portion 220 of cam 114 the platform 14 is in alignment with the web supporting plate 118 and ready to receive a new strip. During the upward movement of arm 124 and platform 14, the knife 196, of course, moves down a little without obstructing the path of the web to be fed onto the platform and the paster bar 208 moves up to dwell so that its applicator point 210 emerges from the paste to drain off the surplus paste.
The platform 14 is inverted (FIG. 1) as it moves through about degrees to the rolling apron to deposit the strip S. Consequently, the daub of paste P (FIG. 4) is on top, so it will adhere to the overlying binder B (FIGS. 4 and 8) which is then deposited on the apron by the binder transfer Z. The motion of the mechanism comprising the conveyor and applicator platform 14 is timed to move to the rolling apron prior to the arrival of the binder transfer Z. At this time there is no suction in the chamber 232 but the chamber 242 underlying the strip S is always under suction as mentioned above. The binder transfer Z does not in itself form a part of this invention and may be of the type construction shown in the patent to Wheeler No. 2,287,004 dated June 16, 1942. For this reason further description of the binder transfer Z is; thought unnecessary.
The strip S is firmly united by the paste to the head end of the binder during bunch rolling operation without shifting or failure of pickup.
As illustrated in FIG. 4, the trailing end E of the reinforcing strip S projects slightly beyond the trailing end of the binder. A line of paste G is applied to this end by paste applying device D (FIG. 1) to seal the bunch after rolling, the strip S being wound outside the binder B as illustrated in FIG. 7. Paste applying device D, illustrated in FIG. 1, is substantially the same as the one shown and described in my Letters Patent 2,391,294 issued on December 18, 1945. A continuously rotating wheel 250 partly submerged in a paste pot 252 supplies paste to a suitable paste applying roller 254 loosely mounted on a shaft 256' adjustably secured to an arm 258 attached to a lever 26% mounted on an oscillating shaft 262 actuated through an arm 264 and linkage 266 by a cam operated driving mechanism (not shown).
After the binder B is placed over the strip S on the apron A by the binder transfer, the arm 26% swings in the direction of the arrow in FIG. 1 and thus brings the paste: applying roller 254 in contact with the end portion E of the strip S and applies a line of paste in the same manner as disclosed in the above mentioned patent 2,391,294. The arm 26%, of course, swings back again to permit the bunch forming operation which occurs immediately after the retreat of the paste roller 254.
The elongated slots 26 in the supporting plate 24 and the elongated slot 121 in the platform supporting flange 122 of hollow arm 124 permit the entire reinforcing stripapplicator apparatus to be adjusted and shifted to place the strip in any desired position on the rolling apron. This adjustability provides effective positioning of the strip S with various shapes and sizes of cigar bind-er. The length of the reinforcing strip, which varies with the diameter at the cigar head, can be regulated by shifting the. crank pin 110 in the slot 112 of cam 114. The top wall of the rolling table chamber 232 is provided with a number of additional threaded holes 268 (FIG. 3) permitting the auxiliary suction chamber 242 to be shifted for varied placement of the strip on the rolling apron.
't is evident that the device may be employed to place the reinforcing strip on top of the binder as shown in FIG. 4A. However, this results in the strip being located within the binder which I believe to be less desirable although it may be preferred by some. If desired, the paste would then be placed on the top of the strip, as shown in FIG. 5A, instead of the bottom as illustrated in FIG. 5. In any case, I know of no device that will with sligdlt modification as in timing apply the strip on either selected side of the binder.
Reference to FIG. 5A shows the arrangement for applying the paste to a spot on the upper surface of the reinforcing strip S while the strip rests on the carrier platform 14. The applicator 217 is secured through an arm 207 and a bearing to a shaft 2% which is rotatably mounted in a bracket 187 which is secured to supporting plate 24. The shaft 2tl5 may be rotated by a conventional linkage under control of a cam arranged to impart the required motion.
As seen in FIG. 4A, the reinforcing strip is applied to the upper surface of the binder Bl. Due to the inversion of reinforcing strip S during the transfer operation, the daub of paste which was applied to the upper surface of strip S now is sandwiched in a small localized area P1 between the strip S and the binder B1. The paster mechanism D of FIGS, 1 and 4 operates in the manner heretofore described. The strip S is now shortened to permit the application of the paste to the usual area of the binder, which is now the exterior element of the pair to permit the pasting of the binder upon itself at the finish of the rolling operation with the reinforcing strip S concealed within and on the head end of the bunch.
I claim:
ll.
