UNITED STATES PACKAGING MACHINE.A

Application Med May 28, 1921. Serial No. 473,295.

To all whom it may concern:

Beit known that AI, A DoLrH CHARLES van Stura, a citizen of the United States, 4and a resident of Nashua, in the county of Hillsborough and State of New Hampshire, have invented an Improvement in Packaging Machines, 4of which the following descripti'on,"in connection with the accompanying drawings, is a-sfzpccificatiim` like characters on vthe drawings representingr like parts.

"This invention relates to packaging nuichines, being more particularly concerned with the art of rolling sheets of waxed paper -onlzoa core such as a cardboard tube `and wrapping thes'ame in a sheet ot paper suitably fastened in place as by being crimped vand ttucked into the ends of the tube.. Theinvention aims to provide a lnnchine to perform the rolling and wrapping ,operations which heretofore have been per- ''ormed byhand. 4

My invention will be best understood by reference to the. following taken in connection -witli the accompanying drawirigs'of one specific embodiment there-` of, while its sco e will be more particularly pointed out in t ie appended claims.

In tfhe drawings: Y.

Figi 14 and 1D together constitute a sido elevation of a packaging machine exempliiyingpmy invention;

Fig.- 2 is a, side elevation similar to Fig. 1^, but showing someof thc working parts in another position;

Fig; 3 is a plan partly in section on line 33 of Fig. 2; 4

Fig. 4 is a. plan partly in section on line 4 4 0f Fig. 2, but sliowing some of the part in another positionl;

Fig. 6. is a sectional View on line. (l-( of Fig. 1^; and

Figs. 7 to 10 inclusive illustratil various steps in the operation of crimping and turking the wrapper into the ends of ille lube.

Referring to the'drau'ings and to the cm- `the pile to apoint where description when bodiment of my invention which is-illusl trated therein, I have shown for purposes of exemplilication apackaging machine in which a pile `continuing the desired number of sheets of wnxed'paper is received by u paper feeding mechanism Vwhich conveys it is assembled with a suitable core such as n' cardboard tube by a feeding mechanism which deposits the tubes one by one onto the respective piles of paper. mechanism then seize the sheets und tube and 'rotate the latter thereby winding the sheets thereonto. A sheet of wrapping pa- Grippers of a winding per is then brought into the patti of the package and is wrapped about. the latter by a wrapping mechanism which then crimps the ends of the wrapper and tucks them into the ends of the tube. The packageY when thus wrapped passes from t-hev'rap- 4 ping mechanism to a delivery mechanism which conveys the packages to a convenient point for removal by an operative. lVhilethe present'l embodiment of-my invention requires the intervention of operatives, it should be understood that this is not 'at Vall essential, but is done forV the sake of simplicity. These .mechanisms will be dc scribed in the order in which they operate on n gilfen package. followed by a description of the general operation of the machine as a whole.

I will first describe the waxed papcrfeeding mechanism, reference being lad lirst to Figure l. A pile of sheets of the paper` usually a dozen, is laced upon n set of conveyor belts 12 winch connect pulleys 1l .and 16 (the latter being best shown in Fig.

5) and extend across a plat-en 18. YLateral guides 20 spaced apart u proper distance for the width of the sheets guide thc latter and insure a proper lateral registration. The 'conveyor belts carry the `pile of sheets forward and bring them against a stop 22 (ser the lou'rr lct't hand part of Fig. 5) which brings the sheets to a state of rest and proper front registration.

The feeding mechanism for the cardlmard tube will now be described, reference being had at lirst to Fi 1B. The tubes are placed in a chute 24 rom which they gravitatc onto a set of conveyor belts 26 connecting pulleys 28 and 30' (the latter being best shown in 5) and traveling across a lplat/en 32. ,i lle'conveyor bei. l advance a procession of the tubes with t eir periph- 0 cries in contact with one another to a downwardly inclined chute 34 down which they 4gravitate under the control 'of an escapement mechanismA now to be described..\

The esca ement herein shown comprises a rocker 3 Vhavin two arms Q8 and 40 which are alternate y-brought intmthe path ogthe tubes by a rockin motion. When the,v arm 38 is elevated, t e arm 40 is depred and serves as a stop to holdV back the'entire row of tubes by the foremost tube of the procession. When, however; the rocker is turned clockwise as viewed in Fig. 5 the arm 40 is elevated and Vthe arm 38,;1s

leases the foremost tube and permits the latter to gravitate down the chute, but the arm 38 prevents the next succeeding tube from following. When, therefore, the

rocker is again turned in the reverse direction to its initial position the arm 40 is depressed into thepath of the next tube and intercepts the latter when it is released by the elevation of the arm 38.

The escapement rocker is actuated by a suitable mechanism herein a rocking shaft '42 to which is securedganarm 44 connected by a. pitman 46 to an eccentric strap 48 which encircles and is actuated by an eccentric 5 0, the latter bein" suitably secured as 0 by a ke 52 toa shall?T 140. Rotation of this sha t' therefore imparts a rocking motion to the esca ement rocker and insures the delivery of tlie tube'sfone at a time onto the successive piles of paper brought to the 5 `assembling point by the paper feeding mechanism. In Fi 5 a tube is shown resting upon pile of tie sheets l)reparatory to t ge operation of winding the atter upon the The winding mechanism w-i-ll now be described, r eferenee being had to Figs. 4 and 6. The winding mechanism is in duplicate, there being one for each end of the tubephence it Will be necessary to describe only o ne in detail. Adjacentto each end of the tube andaxially aligned therewith at the point where the latter is deposited onto the pile of sheets is a suitable holder 56. In the .present example the holder comprises a tapered plug 58 terminating in a cylindrical portion 60 whose diameter is. such that it snugly lits the internalsurtace of the tube. The tapered ortion insures easy entrance of the plug without danger of misalignment or lack of proper registration at the comengagement. with depressed. This action re-' ulencclncnt of its advance into the tube. rlhc holder is herein provided with a. shoulder (i2 which brings up against the end of the tube and thus the latter is clamped end Y wise betwt `n the shoulders of the two holders. Thedholdcr is carried by suitable4 means herein a plunger 64 preferably a rotatablespindle mounted to turn iu suitable bearings 66. A suitable plunger retracting compression spring 68 herein hclically coiled about the plunger and bearing against abutments 70 and 72, one secured to the plunger, constantly tends to urge the latter 1n an outward directiom-that is to say out of 'engagement with the tube. A suitiible latch, herein a lever 74 is adapted to enter a circumferential groove 76 in the plun fer and to retainthe latter in its inwa position in opposition to the force exerted )y the spring 68.

Inward movement of the plunger is herein eliectcd by the use of a lever 78 fulcrumed at 8O and operated by a caniroll 82 cooperating with a cam 84 lsecured to a cam shaft 86. A suitable sprin 88 maintains thccam roll in contact witi the cam and restores the cam lever to its initial position after each inward movement of the plunger.

One convenient way of Winding the paper on the tube is to rotate the latter While advancing it along and in Contact with a Suitable surface. To this end, each plunger is carried by a suitable carriage 90 of which the plunger bearings 66 in the present ihstance form a part (see Fig. 4). This car- 100 riage is guided by suitable guides 92, herein vertically arranged, that is to say perpendicularly to the path of feeding moyenient of the pile of sheets before the latter is assembled with the tube. The carriage 106 is reciprocated on the uideslby suitable mechanism presently to e described.

Since the sheets are to be wound upon a tube, there should be means provided to secure the forward edges of the sheets to the 110 tube preparatory to and during the rotation of the tube, while the sheets are being wrapped about the latter. To this end, I have herein provided a gripper 94 associated with each holder 56, said gripper in 116 the present example being in the form of a lever fulcrumed at 96 on a collar98 fixedly.' secured to the plunger 64. This gripper is actuated by suitable means herein a link 100 pivoted at.102 to the gripper 94 and at 104 *1,20 to a collar 106 mounted to slide'axially on the plunger -and normally held in a re` tracted position by a light spring 108,`here'` in helically coiled about the plunger andl resting at its opposite ends against the col` 125 lars 98 and 106, respectively.

The relationship between the described -pivotal connections is such that when the sliding collar 106 is thrust forward in. opposition to the slight resistance presented "0 by the spring 108` the pivot 10ft crosses a. dead renter, so to speak, by passing the pivot 10;)1 .thus preventing backward Inovement of the sliding r-olla r and heure ioeking the gripper $14 after the latter has been brought into grippingy engagement with the eheets. Since the evlindrieal portion 6() of the holder .'Tti snugly tits4 the interior of the tube, the hitter cannot eollapse and hence the Sheets are iirnily griiped against the outer circumferential suriare ot the tube. lt Should be here understood that the Spring 108 is so weak that it is insullieient at this time to move the` eollar 10G in an outward direction. 'hen. hmvever. the proper moment arriveel for the release ot the grippers, this is effected by suitable means herein. a. stationary eam Vlill against whieh the inner end ot' the slidilnr Collar 106 is brought tol ward the close o1' tbe upward travel of the rarriage 90. By thi?4 means the pivot 104V 'eonneeting the sliding" Collar 106 and link 100 iS moved in the other direction past the dead center presented b v the pivot 102, and the eollar brings up against a 'suitable fixed stop 112. herein a eollar seeured to the plunger. The slidingy collar is held in this position by the spring 108 and the gripper is held in its outward or retravted position until such time as the collar isagvin thrust forward b v suitable mechanism sueh as that now to be described.

Referringr to Fig. 4, the collar 106 advanced alone: the plunger G4 b v a cam lever 114 fulernued at 116 and having: a cam roll 118 cooperatin;y with a earn 120 secured to the Cain shaft SG hereinbefore referred to. The cani is suitably shaped to canse the ad vanee of the sliding' eollar and a` consequent gripping movenu-nt of the gripper 94 at the proper time in the operation ot' the maehine.--that to sav at the moment after the tube has been deposited on the pile of sheets, as represented at the lower le'l't hand part ot' Figure lt should be understood, of eourse, that subsequently when the carriage eomrnenees its u )ward travel the collar 106 will move out o engagement with the eain lever 114 but that the collar will now be held in its advaneed position by the togglelike eteet of the link 100. lt should also be understood that. during: the upward vtravel ot the carriage the plunger will move out of registration with ita artuating lever T8. but that the plunger will be held in its advanced position by the engagement of the latch T4 with the groove T6. iVhen, however. the Carriage reaches the proper point in its upward travel and after the release ot the gripper from the paper the holder 56 should be withdrawn from the tube, This is areomplished lrv the engagement ot' the lati-h T4 with a fixed @lop 122 against whieh the lateh is brought toward the "lose of the upward movement otI the carriage.

Vertical movement of eaeh carriage is herein aeeompiisbed b v the use ot a pinion 124 meahinpr with a rat-li 126. The pinion 124 is nuitabljl nplined on the plunger ol and thu'n rotates the latter while till allow ing: it to slide lengthwise, the pinion in the meantime beingr held. against axial movi ment of the bearing-a liti between whit-h il is rereivml.y as beet shown in Fig. -l-. Assuming,r the raek to be held fixed and the rar riage advanced lengthwise of the ravit. naturall)7 the pinion would rotate an a consequenee of its advanoe along the rat-k and the plunger with its carrier and gripper would-rotate and Cause the windinl;r of the paper on the lube during the upward travel of the carriage. This is the artion whieh takes plaee duringr a part, ot the upward travel of the earriagfe. but the artion is modified h v stopping: the rotation olI the pinion at a eert-ain point through the intervention of mechanism which cannes'` the rack temporarilj,Y to advanee with the earriage and at the saule speed. This` naturally stops the rotation of the pinion.

lteeiproration of the earriafge in herein ad romplished b v the uw ol a lever 12H tulerunied a1 13H and provided with a forked end 13:2 in whieh in received a hlm-li 131 pivotallv mounted on the plunge: iS-l (eee Fig. i). ilvpward and downwaro ewingging movement of the lever is herein ellieried b v a link 136 pivoted at one end to the lever and at its other end to a crank 13S. the latter being Secured to and driven by a shaft 140. Rotation ot' the latter is therefore aeeornpanied by vertical reeiproeation o1 the carriage 90.

In order that the rack may he held sta-- tionary at timeev and at other times allowed to travel vertieallv as previously explained. the raeit is mounted to slide vertically in upper and lower guides 142 and 144 and there is provided a lsuitable ,apringpreesed detent, herein a roller 146 Carried b \y a lever 148 and arranged in rolling eontart with one`edge of the rari: bar. 'lhe latter is provided with a depression 150 whit-l1 the roller enters under the influence of a suitable spring 15:2. iter the sheets have been wrapped about the tube. it is desirable that the rotation oi1 [he latter hall vease during the applieation ol' a dieet ol wrapping paper an hereinafter explained. lrevioui;v to this.` the rack bar is held against vertical movement by the engagement of the springpressed roller 14o with the depression 150, the degree of resistance being Suttieient to enforce rotation ot' the pinion 124. W'hen, however, it is desired that the rotation of the pinion shall cease, the raek is advanced and the detent is thrown out by the mechanism wliieh l will now dearribe,

link lof-l pivoted at 151': to the raeh har is provided with a `alot 15H which reA oeives a pin 160 carried by the carriage reciprocating lever 12H. The length and location ot the slot with relation to the pin is such that during the first part of the upward travel of thi` carriage the pin travels idly in the slot and hence causes no movement of the rari; bar. During this period, the tube is rotated to wrap the sheets of paper thereon. by rolling the park age on a suitable platen herein a springpressed follower 1132. pivoted at itil and urged against the package by a sp1-lng ltt` its movement being limited by a suitable fixed stop 1Gb. (see Fig. 5). vWhen` however, the pin brings up against the upper end of the slot` the rarli bar is caused to rise at a speed equal to that ot the carriage. lt follows that there is no relative move ment of the rack and pinion,--hence the latter does not rotate and the holder .Viti and gripper ill are held against` rotatiolriluring the application of a wrapper. as will now be explained.

The wrapping mechanism willrnow be :lr-f scribed, reference being had to Fig. 5. Arranged transwrsely of the path of the parhr4 ageiis a platen 170. provided with lateral guides 172. A sheet of wrapping paper of the proper size is laid upon this platen between the guides and is advanced across an opening 174 provided in the platen until it brings up against a stop 11:6. Preferablyv the stop is so situated that the rear edge of Athe wrapping paper is somewhat farther from the renter of the tube than the forward edge. Above the opening l'f-l is a pair of v `rtical guides .1721, whose lower edges are spaced from the upper snrt'ace ot the platen a sutlieient distance to allow the wrapping paper to be introduced beneath the guides. The latter are simeed apart a distance slightly greater than the combined diameter of the tube and the sheets wound thereon. When, therefore, during the npward travel of the carriage, the package brings up against, the sheet of wrapping paper, the latter is removed from the platen and is wrapped part way around the parliage by being passed between the guides. 1111s leaves the wrapper with two depending marginal portions which must be brought together and lapped one over the other.

The first ste in this vr ii fr r i -tion p i app ig )pera is performed by one or more grippers 18o, pivoted at 182 on` a` horizontally reciprocating carriage 18a carrying a pair of 186 and 1R@ between which the package is received. A suitable spring 1.9() connected to the griliper iti() constantly tends to carry the latter into gripping engagement with the package. Assuming the ripper to have been opened against the action of the springr by Suitable mechanism presently to be den scribed, the package is inserted between the,

jaws 13G and 18H after which the gripper Intl closes on one flap of the wrapper and wraps the latter about the package, as shown in Fig. 5. The other iap is lapped over the iii-st during and as a consequence ot the travel of the carriage from the position shown in full lines in Fig. 5 to the position shown in dotted lines therein in a manner now to be described.

The carriage is mounted on suitable guides herein a pair of rods 192 on which it is reeiproeated by appropriate mechanism, herein a link 194 pivotally connected at one end to the carriage and at its other end to a iever 195 secured to a rock shaft 196 to which is also secured a segmental gear 19S meshing with another segmental gear 200. The latter is mounted to rock on a stud 202 and is provided with an arln 204 carrying a pin 206 received in a slot 208 provided in a linl El() pivoted at 2.12 to the lever 128 here- 'nbefore described. Rocking movement of the latter is therefore accompanied by reciprocating movement of the carriage on its: guides. but owing to the provision of the slot :20S the carriage has a period of rest at cae i cnil ot' its travel.

The grippers 1H() having closed upon one flap of the wrapper, as represented in fail lines at the left-hand side of Fig, 5 should retain their grip thereon until after the completion of the wrapping operation and subsequently the grippers should open to release the completed package and should ber in readiness for the reception of a second package upon the return of the carriage toward the position shown in full lines in Fig. To this end, I have herein provided suitable means consequent upon movement of the carriage toward the left in Fig. 5 to cause the grippers to open, but on the other hand, to remain closed upon the package during the subsequent travel of the carriage toward the. right. In the present example, each gripper carries a rocking lever 214, pivoted at 216 thereon, and having an arm 21S which is normally held in an upstanding position by a spring 222. Movement of the lever under the influence of the spring is limited by a suitable stop, herein a shoulder 225i presented by the upper end of the gripper 180. On the other hand, the roeking lever is free to be rocked in the opposite direction in opposition to the spring by a plate 22S disposed in the path of the upper end ot' the lever, as shown in Fig. 5. The

length of the plate with respect to the travel ot the carriage is such that when the latter moves toward the right the lever is rocked idly in one direction in opposition to the spring as the lever passes beneath the plate, but on the other hand when the carriage travels toward the left from the positon rep resented in dotted lines in Fig. 5, the` upper end of the rocking lever, after traveling a 4 shown hanging .straight short distance, brings up against the right hand eiid of the plate and since tlielever cannot rotate clockwise, owing to the prov!- V sion of the stop 224, the lev'er and the gripper by which it is carried will be rocked as a unit about the fiileruni vot" the gripper. The gripper thus being opened, remains open iiiitil the rocking lever 2lH clears the lett-hand end of the plate 22H,`whereupon the gripper thus being released and allowed to swing under the 19t] closes upon the package and wraps one llap of the wrapper about the package as shown in full lines at the left-hand side of Fig.

ln order to enforce the period of rest provided for by the slot 208, I Vpreferably provide, suitable detent means herein comprisiiier a disk 230 secured to the rock shaft ltit and provided with two depressions 232 and 21H. either of which is adapted to receive a.

roller 22H3 carried by a lever 2258 provided wiili a spring 24.() which urges the roller into contat-t with the peri iheryA ot` the disk. When the roller is heh by the pressure of thil spring iii eitherdepression, sollicitent resistance is presented to prevent; the\Shaft roi-king until the pin 206 brings; up against one end or the other of the slot .tin as the ease may be. whereupon the roller rides out of the depression and` the rock shaft turns. thereby imparting the desired luoveiiii'nt to the carriage. i

During the travel ol' the carriage from the position represented i'n full lines in Fig. 5 toward the position shown in dotted lilies therein, the second Hap of the wrapper i downward at the should be. lapped over upon the first and held there until the ends of the. wrap ier have ,been ends of t ie tube. (lue accomplishing this is by 4 platen 242 arranged in the. path of the depending flap and haring a wiping action which wraps the saine over and laps itupon' the other edge of the wrapper. Preferably this platen is suitably mounted lo yield radially with respect to the tube and herein is mounted upon a pivot 241 about which it is rocked and urged in an' upward direction by a spring 2 46. suitable stop 24H' limits the upward iiiovement under the influence of the spring. If desired, the forward or free edge of the platen may be bevelled or curved in a downward direction as at 250 to make sure that the iackiige will ride up n the platen and (le-press the latter against the tension of the' spring.

Both margins ofthe wrapper-now having been wra` ped about the package and lapped Oii'e on tllie other and'be-in f firmly held in this position, the next ste is to crimp the endsof the wrapper andJ tuck them into the ends of the tube. I will now describe left of Fig.

convenient way of inlliicnce of its springl cooperating with crimped into the` simply providing a the crimping and tiieking mechanism, reference being had to Fig. 3. The crimping vand tueking is performed by a plurality of `lingers of any suitable number, herein four, fiilerunied on pivots 254 on a collar 2.36 likt-,illy secured to latter being mounted to slide horizontally in a guide 260. The lplunger is reciproeated by aV suitable mechanism, herein a lever 262 fiilcrumed at 264 and connected by a link 266 to. a lever 268, the latter being fulcriiined 4at 2T() and carrying a. cani roll 27,2 a cani 274 secured to a cani shaft 276.. A! suitable spring 278, herein encircling the/link 266, bears at one end againsta fixed abutment 280 and at its other end against an abutment 282 carried by the link, said spring servin, r to maintain engagement; of the. eanrroll `with the cam and to restore the plunger to its initial outward position after having been thrust iuwaidly bv the action of the cani.

lnwari movenient'of the plunger is utilized for two purposes, first to enlise the tin' gers to close upon and crimp the wrapper inwardly. and second, to thrust the crimped wrapper into the ends of the tube. l vement way of producing',r the closing and opening movement of the lingers ,is by utilizing the reciprocating movements of the plunger 25H. To this end, I have herein provided a collar 284 mounted to slide engthii'ise ot the plunger 258 and connected to the lingers 252 by links 286, the arrangeiutiit heilig such that slitting movement of the collar is areoiilpunied by Opening 0r closing niort-nient of the lingers aceordinr to the direction in which the collar is moved. A suitable spring-28H, herein lielically coiled about the plungeig'is interlxisedbetwee-n the' ixed collar 256 and the slidingv colla-r 284 alid constantly 4tends to a4 rearward or outward direct-ion; In other words. the fingers are opened by the action of the spring.

.The tingersare closed i'n opposition. vto the spring by a lever 290, one. end of which is forked and provided with ins 292 received in a groove 294A prt'ividedl in the sliding collar 284, While the other end carries it cani roll 296 cooperating -with a. fixed cam 298. The lever 29`is fulcrumed at 300 on a collar 302- securedto the plunger 258. It follows that reciprocating inovementof the latter is accompanied by opening or closing movement of the tinfvers according to the Adireetionrin \\l1icli-.tlie plunger is moved. 'l`l`ie shape ofthe cani is such that the plunger at first travels inward without closing movement of the fingers. The latter, therefore, ad 'ance until they are inwardly beyond' the end of the wrapper and adjacent the end of the tube. At this point, a Step in theveaui causes the sliding collar 284 to lie advanced faster than the plunger 258,

a plunger 258, theV One coninove thel latter yin thereby causing the fingers to be closed upon the wrapper andto,4 crimp the seme. The fingeis continue to close until they are closed sufficiently to enter-the tube,v whereupon the closing movement ceases and continued forward movement of the simply pushes the Crim edge o@ the peperlinto the interior of At e tube. This vhaving been done, the tin rs -recede andere restored to their initia, position b v a reversal of the foregoing movement. i f i The wrapping operation is now completed and nothing remains to, dene but to die` charge the finished` `l I Hfst StP is to move thel piu; Vege the position just described (iii alignment with the plungers 258) to a point above an entrence'i of e chute 306. Thiais accomplished dur.

ing the t'revel of the horizontal 1g'serriege'to ward its animi posities, (wwwa in@ im Fig. 5). It will beremembeed thptdiiring this movement ofthe'carriagetle grippers 180 are releasedf from-the -1 age by the action of the fixed on the rockers 218 carried bythefgrippers. This occurs lwhen the l jirlsj immediately above the entrance 304 o flhefchiite 306. .vilt

follows that the peckl is" 't into the chute and gravita down e latter onto a set of feed belts308 which qonnect pulleys 310 endl 312 1") end travel across a. platen 31 Fig. 5 Y. The chute is preferably'provide `vbitll'fsri e walls or guides 316 which are pfolo'i'i-' along the sides of the platen' Bl'tend tius guide the ends of the peck'kf tofafconvenieiit point of delivery. In e present example, the packages bring up agnst swell-318, at. which point they ma hund of im operative. might be omitted and the.packages allowed to fall into a. suitable receptacle.

The machine is provided with a Suitable frame, herein comprisingitu-pair Vo'f side frames 320 affording beeringsjor the several shafts and oonnectedjto eechother by several cross ties which will now de scribed, reference being had= -first to Fig,v 5.

, where the tube is deposited on the pile of ,alignment with the crimping and sheets. The tube and sheets are then grasped by the cooperative action of the carriers 56 and grippers 94, whereiiponthe tube commences to rotate and wind the sheets thereon. An operative feeds wrappers c one at a time at the proper instant into the path of the tube with the sheets wound thereon, and oontinued upward movement'of the latter results in the wrapper being wra ped part way about the sheets as shown at t e upper lefthand part of Fig, 5. The partially wra ipod package is then carried in a horizontal irection toward the right as viewed in `Fig. 5 into tucking mechanism. Toward the close of this movement the edges of the wrapper are lap ed one over the other and the wrapper is tiien in lreadiness to have its c nds crimped and tucked, which operation now takes place under the action of the crimping and tucking inechanism, and finally the completed package is deposited into the outlet chute and is carried away by the discharge feed thereto, what I axis of the belts to the point of delivery.
