United States Patent "O SPLICING MACHINE Richard A. Butler, Jr., Palmer Road, Monson, Mass.
Filed Feb. 6, 1957, Ser. No. 638,613
1 Claim. (Cl. 154-423) My invention relates to new and useful improvements in a splicing machine and is directed more particularly to improvements in the means for preparing a web roll for splicing to a web running to a packaging machine, printing machine, box-making machine, or similar web consuming machine, and to the means for the making of the splice to the roll when thus prepared.
It is the principal object of my invention to provide a novel and improved construction of the type in which a web-renewing mechanism is employed for use in the supply of webs to a web-consuming machine wherein provision is made to enable the web-supply to be maintained without stopping the machine by arranging a replacement web-roll and the running web to engage and adhere to one another so that the web of the replacement roll commences to be drawn from the roll at which time the running and expiring web is severed or depleted, all of which eliminates objectionable inconveniences now present in the known prior art devices and which will operate with a maximum amount of ease and with a minimum degree of efiort.
One of the primary purposes ofmy invention is to provide structural and operational improvements in 'devices of the class to which reference has been made, which improvement-s not only simplify the structure as such, but also provide important distinct advanta es in strength, durability, elficiency and the like. I
Stated otherwise, herein as a mechanism iforrautomatically splicing the leading end ofone roll of webio the trailing end of a diminishing or an exhausted web supply as applicable for use in conjunction with web-consuming machines in such manner as to eliminate the necessity The paper or other flexible web which is fed to print- I ing presses or other web-consuming apparatus runs from web rolls which must be replaced periodically as they are consumed.
Successful operation of web-consuming machines depends in large measure on the maintenance of a continuous supply of paper thereto.
This invention envisions a high speed web roll replacement involving apparatus in which the web 'of a new or reserve roll bearing a layer of adhesive at its leading end is brought to a position adjacent the web. of a running roll running to the web-consuming apparatus. The leading end of the fresh roll web is then spliced to the running web which thereafter runs out or expires.
The fresh and running web rolls are rotatably carried by movable supports, such as the spider arms of;a.multiarmed reel which are rotatable to bring successive fres rolls to the splicing position.
. Itincludes means for-effecting a-splice-of'the leading end of the paper on the new or reserve roll to therunning web as the running web roll is about to expire so thatpa'pe'r supply to the web-consuming machine is funinterrupted.
Herein, the mechanism is provided with a-sensing device which automatically sets the, mechanism in motion as the trailing end of the diminishing roll from which the web is being fed passesjtherepast so as to make unnecessary manual intervention to accomplish the desired results.
Herein, a pair of spiders is employed, same having three roll positions, one for a running roll from which the web is drawn, a second for a replacement roll the Web of which is joined as described to the web passing from the running roll, and the third for a freshly loaded roll, the various rolls successively being brought into loading, replacement and running positions.
The spiders includes a plurality of angularly spaced arms for receiving the ends of the core shafts projecting from the rolls for thesupport thereof relative thereto.
These arms are arranged in such spaced relation that when one setof arms is in substantially upright unwinding position to support the roll therein for unwinding, the next successive set of arms is in generally horizontal positionto receive a fullreplenishing roll, and the next successive set ofjarrns is in the unloading position for the autornaticrelease of the core shaft of the exhausted roll.
Other prime objects of my-invention include; first, 'the securernent of a higher degree of accuracy aiid greater degree of variety in the manner of work performed therewith than has heretofore been possible with prior "device's known in the art; second, the a tainmemiera higher speed of construction [and assembly-of the device due to its simplification of design; third, the attainment of a flexibility or a capability of adjustment by which a large variety of work can be producedgby means of the same device; fourth, the achievement of a greater ease in adjustment and repairs; .fifth, the provisions .of a-cons'tructionwhich-may be readily installed with respect to the various purposes for which it is intended, and sixth, the provision of such other improvements in and relating to splicing apparatus of, the typeabove referred to as are hereinafter described-and claimed.
the above primary objects in view, it is, still. another object of my invention to provide a construction of the above described character in which the number of operating parts is greatly reduced and which is compact injaccordance with the demands and desires of manufacturers and purchasers alike and which is not only distinctive in its appearance and practical in itsvaluebut also reliable in its operation and eflicient in its use.
It is still a further object to provide a device which is constructed of relatively simple parts which are. adapted to be readily assembled and which when once assembled are positively and securely retained in operative relationship and which cannot be readilyseparated from each other, either accidentally or otherwise.
In the accompanying drawing, I have illustrated a complete example of a physical embodiment of the inventioh in which the parts are combined and arranged in accordance with one mode which I have devised for the practical application of the principles of the invention. It will be understood however that changes-and alterations are contemplated and maybe .made in these exemplifying drawings and mechanical structures, within the scope of the claims, without departing from the principles of the invention.

These names however are intended to be as generic in their, application as the art will permit.
Referring now to the drawing more in detail, in which similar characters of, reference indicate corresponding parts'in thesjeveral figures andreferring more particularly 1Transverse1y spacedsideframes, such as 2, are connectedby an upper member 4, and a lower floor member 6. Members 4 and 6 are secured at opposite ends to the walls 8 of the frames, as by rivets, weldments, or the The frames have inwardly turned flanges 10 on the formerly occupied by the arms 23 and the empty arbor 30 of the now exhausted roll is free to drop away from the arms and onto the wall member 6, it being appreciated that no clamps or the like are employed in connection with the arms so as tohoId-the arbors relative to the arms.
; The arms 23 may now be called empty.

Atsaid table, the endof the web is pre pared by mechanism associated therewith for subsequent releasable attachment to T the applicator whereby the leading end may be eventually secured to the trailing end of a web being'fedthrough the feed rolls. 7 T Webs of material such as paper used in' wrapping machines are sometimes printed or are otherwise provided with panels of indiciawhich are so arranged that when wrapped around object orflarticle. the printed matter or the panels. fit the object in a predetermined manner so that the printed matter. or' the panels register with the sides of the object. Accordingly the webs have printed matter or. panels spaced-longitudinally thereof in such 'frontQrear and upper edgesthereof. The forward side =orjfront of the machine is indicated by F.
An upper. rock shaft or transfer arm shaft 12 is oscillatablein bearings secured to the walls 8 ofthe frames 2, as are an upper, feed or pull roll shaft "14 having an upp er feed or pull roll 16 and a lower feed or pull roll "shaft 181havinga lower feed or pull roll 20.
The lower'shaft 18 is driven from the web consuming machine, such as a wrapping machine which uses the web of wrapping material fed thereto by the machine hereof. A pair of spiders, each having a plurality of angularly 'spaced arms or paper reel carriages 22, 23 and 25 which are fixed to a carriage shaft 24 having its opposite ends =journalled in suitable hearings in the walls 8 of the side frames2.-
f Outer ends of the arms 22, 23 and 25 are provided with sockets 26, as shown to receive and support oppo site ends. of arbors'28 and 30 of rolls of web material such as wrapping paper.
v The web W from the roll on the arbor 30 is shown as extending upwardly from the arms 23 to the bite of the feed rolls 16 and 20. From the feed rolls, the web W passes to the web consuming machine in the direction indicatedby the arrow b. Such web W is identified herein asthe running web roll.
The web W from roll 32 thereof on arbor 28 extends to an applicator or transfer device which is generally indicated by the letter A. Said applicator functions as a web delivery device which is swingable betweena non-operative position when it supports the leading edge of the web W in a ready-to-splice manner to an operative position 'where it secures the leading edge of'the web W to the trailing end of the web W. 1 1
; jT s the final end of theweb W arrives at the feed rolls of the said leading edge of thenew web is applied by theapplicator in substantial register with a panel at the a manner that they are of a width to correspond with the width of the sides of the object or article being wrapped. According to this invention, the panels of the leading edge of the web of the new or replenishing roll register with or, match thepanels of the final end of the old or' exhausted web being fed fromthe machine. The web W extends through a sensing and paper tension means generally indicated by the letter S which con trols the operation of the applicator A.
By preparing the leading edge of the new or replenishing web in a certain way, subsequently to be described,
and by driving .the machine hereof from the web-consuming machine and in timed relation therewith, the panel end of the web about to become exhausted. The applicator is actuated into operating position as the trailing end of the web W passes through and past the sensing mechanism.
' Opposite ends of therock shaft 12 are journalled in bearings, such as 12', fixed to the walls 8 of the side frames, as will be observed by reference to Fig. 8.
Likewise roll shafts 14 and 18 are rotatable in bearings 14 and 18 respectively fixed to the walls 8. See Figs.
9 and .10, V The shaft 18 is the driven shaft and has fixed thereto a sprocket 40, as shown in Fig. 6, for connection by a chain to the web-consuming machine to be supplied with the web material by the machine hereof.
The shaft '24 is journalled at opposite ends in suitable bearings of the side frames 2 and has a worm wheel or carriage worm gear 42 fixed to one end thereof. See Fig. 3. V f
i A carriage worm drive shaft 44, rotatable in a bearing 46 fixed to the adjacent side frame has a worm or carriage worm pinion fixed thereto which is in mesh with the worm 'A hand wheel so fixed to the outer than the shaft 44 facilitates the rotation of the shaft 24 and the counterclockwise movement of the arms 22, 23 and 25. See Figs.
3 and 6. 7 V
amazon Tension arms 52' are loosely-mountedon rock shaft-12 and have non-rotatable tension rolls on thelower depend-.. ing ends thereof for frictionally engaging-thewebbemg:
fed through the feed rolls 16 and 20. See:Fig.. 11;
The rolls 54 may be of rubber,- material adapted to keep the wehtaut:
Pins 56 extend outwardly: from the arms 52a Other pins 58 extend outwardlyfrom tension:wllars 601 fixedi to the rock shaft 12; Said pin's 56 andr8 areconnected by tension springs 61 andfunctioneto tensioncthead acent arm 52 and .to provide the-desired drag on theweb.
The applicator A includes "an elongated lowentransfen' tolower ends of relatively spaced 63: which" are'secured to the rock bar or plate 62 secured levers or transfer arms shaft 12.
An elongated presser ortransfe'r cushion-odwhich'may he formed from a'resilient material such as rubber-ortholike and is secured'to thebar 62 by an upper transfer bar orplate 66.
New web support pins 68 are secured to opposite ends of the bar 62 and extend upwardly therefrom as best shown in Figs. 2, 6 and 11.
A spring return arm 70 is fixed to one end of the rock shaft, as shown in Fig. 6, and a spring 72 hasone end thereof attached thereto. The opposite end of the spring 72 is attached to an anchor 74 of the frame, as will be observed by reference to Fig. 11. This springfunctions to yieldingly hold the applicator A away 'fromthe roll 20 in the non operative position substantiallyas-shown in Figs. 2 and 11.
The leading end of the new web W is represented by 76 in Fig. 2. Across thefree edge of the same is secured an adhesive material such as adhesive tape T of suitable type.
Opposite ends of the tapeT are caught on the pins 66-so that the end 76 of the Web W is supported by the applicator A. The side T of the tape adjacent the roll 20 and the portion extending upwardly beyond the end 76 of the web is tacky.
As the rock shaft 12 is swung clockwise, the pad 64 of the applicator presses the tape T against the web W hearing on the roll 20.
Thus the leading end of the web W is attached to the web W and the panels of the webs are related, as desired.
The applicator is operated as the last end of the web W passes through the sensing mechanism S which operates to bring about this movement of the applicator.
The sensing device includes a pair of parallel, vertically spaced, transversely extending rear sensing rods or arms having their inner ends fixed in a member '82 which is secured to the wall '8 of the adjacent side frame. See Fig. 6.
An elongated tubular, vertically disposed timing shaft 84 is reciprocable and oscillatable in bearings 86 which are fixed to an adjacent side frame, as may be observed by reference to Figs. 7 to inclusive.
A detector or forward sensing rod Or arm 88 has an inner end which is adjustably secured along a vertically extending slot 90 in the shaft The shaft 84 is urged in a clockwise direction, as shown by arrow a in Fig. 10, by a spring '92 having opposite ends attached to anchors '94 and 96 of the shaft 84 and the wall 8 of the adjacent side frame respectively.
Normally the web W being fed by the rolls 16 and '20 passes through the space between the pair of rear sensing rods 80 and 80 and the forward sensing rod 88, as will be observed by reference to Fig. l. The web W prevents counterclockwise movement of the rod 88 between the spaced rods 89. The rod 8 8 is swung to a position in juxtaposition with the front side of the web W and functions to provide a tension thereagainst.
As the trailing end of the web W passes upwardly past the rods, spring 92 functions to turn shaft 84 in the direction of arrow a shown in Fig. 10 so that member 88 passes metal,-or other: suitable;
. 98 and alower (33111110111003.
A timin'greturns'pringwyis disposed around the; shaft-: 84 between the upper bearing 86..and the head; 96',- and: functions 1 to. resist .the. downward movement of: the: shaft from the normal positiomshown-in- Fig; 7 and toreturn; theshaft to saidnormal position when-releasedmswill be: shortly observed:
A timing cam 102-is-fixed toilthe uppenroll shaft 14 for engaging the cam roll"100iof the.head961soas to depress thehead and the shaft downwardly;
A transfer arm follower or lever-104 isfixed'to' the rock shaft: 12 and has a transfer'armfollower cam roll 106 pivoted thereto, as shown;
As :the head-396' is depressed downwardly the nose-97 thereof functions to earn the roll 106 as will be observed;
With web W disposedforwardly of the-pair of rear sensingrods and -80-and rearwardly of'the forward sensing rod 88, the shaft 84 and the-head 96 are disposed in the position shown in Figs. 8, 9 and 10. The upper por-- tion of thehead 96. is disposed at'a side-of the-cam 102 and the lever 1G4. on angularlyrelative thereto. In said position, the head 96 is not engagedby the cam 102 as it rotates with the shaft 14;
As the final end of. the web'W passesupwardly past thesensing rods, rod 88 is released by said web whereby spring: member 92 actuates shaft d-i in' a rotary manner so that roll 1000f the-head '96 is swung to and-through aposi-i tion inver-tical alignment with the cam 101.. which-.issimultaneously being rotatedclockwise.
Cam 102 engages the: roll 1% so'asto cam-thehead 96: and the shaft 8'4..downwardlyv against the action of =the spring 99.
As the head is turned as above referred to, the ledge 98 thereof overlies roll 106 of lever 104 fixed to the rock shaft 12.
As the head is depressed as aforesaid, the ledge 98 engages the roll 106 and earns it so as to actuate the lever 104 and in turn to rotate the rock shaft 12 and to swing it through such an angle as moves the applicator A inwardly toward the feed roll 20.
With the tape T attached to the end of the web W, samev is pressed against the web W so as to secure the leading edge of the web W to the web W.
In such operation, the tape slips off frornthe pins 68 or is ruptured thereby so as to be released therefrom.
The earn 102 quickly impacts the roll of the head I 96, and the spring 92 continues to turn the head to a position beyond and alignment of the cam and roll.
Thereafter the shaft 84 or the head 96' are manually grasped for turning counterclockwise, and the web W is looped outwardly to allow the rod 88 to be swung therepast so as to again be disposed on the outer side of the web. The head. or shaft is then released and the rod rides on the outer side of the web which is backed up by the rods 80.
Means for preparing the leading end of a new web, for its attachment to the trailing end of the web being fed, will now be described, with particular reference being made to Figs. 4 and 5.
Longitudinally spaced brackets 110 are secured to and depend from the transverse member 2. Upper and lower guide rods 112 extend between said brackets and have opposite ends secured thereto.
A slide 113 is slidable on said rods and a spring 114 is connected to anchors 116 and 118 of the slide and wall 8 of the right hand frame respectively. A knife 120 is secured to the slide 113 and has a slitting edge 122. A manually engageable member 124 is carried by the knife 120.
Spring clips 126 have outer ends secured to the upper side of the member 4, as by screws or the like, and are formed at their adjacent inner ends to receive thereunder.-" oppositesideportionsof the leading end of a new web;
soas t'o'hold the end of-the webton the member 4. V
The end ofth'einew w ebmay be shifted so that it .will: betrimmed squarely by the'kniie sas it isimovedto'the; right, and will be trimmedin the desiredrrelation-t'o the en'dmost panel of the old web. I A suppo'rt 128 is fixed to and extendsupwardly from; the transverse member4 and carries a spindle 130- fore the corei132 of a -roll of adhesive tape:134.wA plate 131 on the spindle '130 holds the core in place.
The endof the tape is drawn .under a roll 136 of the support and to theright for the desired length.'- A knife? 138 is provided for cuttingthe tape when the desired lengthhas-been'drawnfrom the roll. The'tapeis applied to the edge of the web at its end,
while the web is held by the'clips, so that approximately.
