7 19 Claims. ((11. 140-93) This invention relates to machines for making wired tags, more especially the conventional identification tags, or markers, that are applied to plants and the like. Such plant tags, are each 5 composed of a rectangularv strip of thin wood about which is looped the midsection of a suitable length of wire whereof the legs are twisted together at their basal portions and are folded against and longitudinally of the tag.

10 The principal object of myinv-ention is the provision of a machine of simple and efiicient construction and operation whereby tie wires are rapidly and uniformly produced and at the same time are securely applied to the tag material.

Other objects Will hereinafter appear.

The machine herein illustrated as an embodiment of my invention includes an element constituting a strip and-wire carrier which is arranged in co-operative relation to aseries of 20 spaced stations atwhich the respective steps for the production of the, wired tags are successively performed, namely, a station having means for applying stripsin succeeding order to and upon a series of spaced parallel'wires which are supported and lengthwise impelled by, the carrier; at station having means for cutting the leading ends of the wires to provide tie lengths at intervals along each succeeding strip, and also having means for bending such lengths about the strip;

Referring to the drawings, 25 designates spaced frame standards and 26 designatesa base there- 21 and 28 designate two spaced parallel shafts. having their bearings in the standards. The rear shaft 21, which is the main drive shaft is operatively connected with the forward shaft 28 by suitable intermittent motion mechanism,

such, for example, as a Geneva stop motion whereof the driving and driven

elements

29 and 30 are fast on the respective shafts. p

Fast on the shaft 28 and intermittently rotatable therewith, is a strip and wire support constituting a carrier by means of which associated strips of wood S and wires W are moved step by step to a series of succeeding stations hereinafter described.

In the present instance each strip S is of suiiicient length for subdivision into four uniform tags, its longitudinal edges having at suitably spaced points notches n adapted to receive and retain the respective tie wires when they are applied to the strip, and such edges being also suitably shaped, as at m, adjacent the notches, to afford chamfered or rounded ends for the respective tags which are severed from the strip. In pursuance of my invention the strip may be preformed to provide a single tag or any desired number of tags.

The carrier in the form illustrated comprises a pair of circular end heads 3| and therebetween a plurality of equally spaced disks 32, in the present instance four. In the periphery of each of the disks are a plurality of equally spaced rectangular recesses 33, in the present instance six. The recesses of the assembled disks are in longitudinal alignment with each other and each set of aligning recesses has loosely seated therein a radially movable bar 34 with extending end portions. This bar constitutes a strip backer mem-- ber between the respective end heads 3|.

Each end head has a series of equally spaced guide openings 35 corresponding in number and relation with the recesses in each of the disks. In each opening is mounted a radially movable plate 36 whereof the outer end extends beyond the periphery of the head and has a suitablydisposed rectangular opening 31 into which the end of the adjacent backer bar 34 extends. Thus the respective ends of the bar are seated within the aligning rectangular openings of a pair of slide plates mounted in the two end heads for limited radial movement therein. The openings 37 are of such form and dimensions that in the outward movement of the end plates 36 the bottoms of the openings bear against the respective ends of the backer bar 34 and push the bar uniformly outward a determined extent, and that in the succeeding inner movement of the end plates the bar is free to resume its position at the bottoms of the recesses of the disks.

Each plate 36 is slidably maintained in the proximate end head by means of gibs 38 which are affixed to the outer face of the head, and also by the flanges 39 of a bracket structure 40 which is fastened to the inner face of the head. The outer end portion of each plate 36 has formed therein adjacent the sides and top of the opening 31, a pair of oppositely disposed angular cam slots 4| in which are slidably fitted studs 42 on the outer faces of a pair of complementary slide blocks 43. These blocks are mounted to slide in an open transverse guideway formed by and between spaced parallel ribs 44 on the inner face of the bracket 40, the body of the latter having therein at the back of and parallel with the guideway a suitable slot 45 through which the studs 42 freely extend, and having also an opening 46 in register with the opening 31 in the adjacent end plate 36.

When the plate is radially shifted the companion blocks 43 are moved endwise a limited extent toward or away from each other by the action of the inclined portions of the cam slots 4| on the studs. The blocks are formed on or secured to the adjacent ends of a pair of complementary

parallel bars

41 and 48 which are slidably mounted on flattened peripheral portions 49 of the disks 42, and therefore as the two pairs of blocks 43 are actuated by virtue of the concurrent movement of the companion end plates 36 the bars 4! and 48 are simultaneously moved in parallelism toward or from. each other. These bars constitute complementary wire bend ing jaws.

The respective slide plates 36 are provided adjacent their inner ends with lateral studs 50 for rolls 5| which run in the races 52 of stationary face cams 53 located adjacent the respective end heads 3| and secured to and supported by the respective frame standards. The cam races are of corresponding contour which is such that during the intermittent rotation of the carrier structure the plates 36 are radially actuated in a manner to effect the periodical closing and opening of the respective pairs of wire bending bars. In the outer faces of these bars are transverse peripheral grooves 54 in alignment with circumferential wire guiding grooves 55 in the respective disks 32. The outer face of each trailing bar 41 has a series of projections 56 spaced from the respective grooves 54, which projections are constructed and arranged to encounter each opposing strip S presented thereto at the station (A) and then advance the strip step by step to succeeding stations.

In the present instance is provided strip-supplying means comprising a skeleton magazine which inclines downwardly to the front of the carrier. The magazine includes upper and lower longitudinal side members, 51, of angle iron, connected at intervals by side pieces 58 and cross-bars 59. The strips S are slidably stacked, face to face, in and between the side members of the magazine and are gradually fed toward the carrier, the lowermost strip being in advance of the adjacent bar 47 during each dwell of the carrier. The downward feeding of the strips contained in the magazine is preferably contributed to by underlying feed belts 60. In each succeeding step of the carrier the lowermost strip in the magazine is advanced by the contiguous projections 56 of the adjacent trailing jaw bar 41 until the strip is in horizontal position at the station B directly above and parallel with the axis of rotation of the carrier. guard bands 6|, which are supported by the magazine, overlie the ends of the strip during its travel to the station B, thus preventing outward displacement of the strip.

When the carrier is at rest, immediately pre- I ceding its step movement, the complementary bars 4'! and 48 which are located at the foot of the magazine are open, and the lowermost strip S in the magazine is supported by the portions of the spaced wires W which span the gap between the bars, the edge notches n of the strip directly overlying the spans of wire. (See Fig. 6.)

The wires, which are drawn from suitable reels (not shown), are directed to the peripheral grooves 55 of the respective disks by means of grooved wheels 62 loose on a shaft 63 which is supported at the front of the carrier and below the delivery end of the magazine. The shaft 63 is supported at its respective ends by suitable pedestals 54 rising from the bed 26. The series of wires as they pass from the wheels 62 are drawn upward within the grooves 55 of the respective disks; thence under and past the delivery end of the magazine to a determined cir- Curved cumferential location (0:) on the respective disks determined location 1/ beyond the strip.

'tionof thisstep of the carrier,

.end "of the .magazine are seated under tension in theitransverse grooves 54 of the adjacent bending-bars. and 48; In the present instance .thereare'six sets of equally spaced clamps which sets. are .arranged around the. disks in alternationwith thepairs of wire bending bars. Each set comprises four aligning members arranged laterally. of and in 'co-operative relation tothe'peripheries of therespective disks. Each clampvmember 65 consists of an angle lever pive oted on a suitably-disposed bracket 66 on one side of the adjacent disk 32, so that the lever can be'actuated to swing .its outer arm upon .or away from and below the periphery of the disk ina manner to clamp or release the opposing wire, as desired. l

fiThe inner arms-of. each set of clamp levers are pivoted, asat '67, to a. rod 68 which is parallel to the axis" of rotation of. the carrier. This rodfreely I-extends through aligning openings in the disks Sand is slidably supported at its ends in therespective end heads 11,. l2-and 13.) A spring 3|irof the carrier. (See Figs. 69 encircling the rod'68 and having its ends bearing against one of the enddisks. 32 and a collarifl on the rod,.norma1ly urges. such rod endwise in a manner to maintain the clamp levers :open or in unclamping position.

One end .of the rod 68 projects. outwardly through'the adjacent end head 3| and is provided' with a roll'il which at a determined interval in the rotation of the carrier rides against a 'suitably disposed cam 12 which is fixed on the adjacent frame standard in spaced relation-to the magazine;

;In the present instance the body of this cam is constituted by a guide block having inclihedend faces 13 and M, respectively. The iinclinedface leis so arranged as to ,force each succeeding roll 1| andits rod 68 inwardly against the action of the proximate spring 69 immediately .precedingthe dwell of the adjacent pair of open wire bending bars at the stripsupply magazine, thus simultaneously swinging to clamping positionupon'the respective disks and their wires the set of clamps which are pivotally connected to such rod. Thereupon in the step of the car- -rier to advance thestrip S from station A to stationB the wires W are drawn along by and with the carrier, thus positioning the strip in horizon-' tal position and with theleading extremities of the respective :underlying wires. extending 12% a ee Coincident with the comple-r the roll I .of the next succeeding clamp actuating rod 68 encoun- Figs. 3; 6 and 7.)

, ters the cam 12 and is thereby lengthwiseshifted to effect the clamping of the wires at the location 0:. Hence the lengths of wire underlying the strip and extending between the points at and :11

are securely held under tension upon the respective disks by means of the adjacent clamps 65.

: While theyare thus held the wire lengths are severed .fromthe bodies of the respective wires,

at. points adjacent the location 0:, by. means of vertically reciprocating cutter blades 15 which are arranged and adapted to co-act with the walls of a row of suitably-disposed transverse slots 16 formed in the peripheries of the respective disks. The severed lengths constitute tie- Ewires. In the present instance the blades 15 are icarried by a cross-head Tl which is supported at .itsends on a pair of vertically reciprocating rods 5:118; One 'o f these rods" extends" through v and is brace and extend below the shaft 21.

@ends of the bars 86 are equipped with rolls 8'! guided in the cam block 12 and the other through i a guide block 19 which is supported by the opposite frame standard. Encircling the rod 18, in the space between the respective members 12 and 19 and the cross-head, are compression springs 8|], which maintain the cross-head and its cutters normally raised a suitable distance above the carrier. The lower ends of the rods 18 are fixed to vertically movable slotted bars 8| which freely embrace and depend below the driven shaft 28 and are jointed at their lower ends by means of links 82 to a pair of levers 83 fulcrumed on suitably-disposed studs 84 on the forward lower ends of the adjacent frame standards. The levers 83 extend to the rear of the standards and are there pivotally connected by means of links 85 to vertically movable slotted bars 86 which also em- The lower the cams 88 are fastened to the hubs of the cams.

In the step of the carrier from station A to station. B the effective straight face of the cam block 'IZmaintains the proximate rod 68 in its wire clamping position. At the end of the step the roll H of this rod bears against the opposing end of a reciprocable stud 89 which is mounted in and transversely of the cam extension 14, which stud, being then temporarily held, maintains the rod 68 in clamping position during the dwell of the carrier at station B and until the stud has been released as will now be described. Depending from a lug 90 on that end of the cross-head 11 adjacent the cam block 12 is a laterally recessed rod 9| which is slidably fitted in the adjacent frame standard so as to co-act with the outer end of the stud 89. The recess 92 of the rod is so located that in the downward stroke of the crosshead, immediately after the .Wires have been severed by the cutters 15, such .recessis positioned at the outer end of the stud 89, thus permitting slight outward retraction of thestud by the resilient pressure thereon of the opposing roll 1| of the rod 68, and consequently releasing the pressure of the clamps 65 on the leading ends of the wire lengths previously severed. Depending also from the cross-head 11 are a series of presser rods 93 which, corresponding in number and spaced relation with the disks 32, overlie the strip S at station E whenthe carrier is at rest. The relation of the presser rods 93, cutters 15 and the cam rod 9| is such that inthe downward stroke of the cross-head immediately following the release of the leading ends of the wire lengths, the presser rods 83 impinge against the opposing strip in a manner to press it and the underlying midsections of the respective wire lengths into the space between the adjacent openwire, bending bars, and also into the underlying recesses 33 of the respective disks and=. upon the backer bar 34, thus bending upward and into the adjacent edge notches n of the strip the respective end portions of the wires, as seen in Fig. 8, it being noted that the top of the strip thus depressed is slightly below the level of the :under faces of the bending bars 41 and 48.

:;: In the'upward stroke of the cross-head I1 virtue of the springs 80 the cutters 15. the presser rods 93 and the cam rod 9! are raised, the latter rod thus camrning the opposing stud 89 to and temporarily maintaining it in its inner or active position in relation to the path of the roll II of the next succeeding clamp actuating rod 68.

In Fig. 19 of the drawings are illustrated a portion of a strip and a length of tie-wire as they are relatively disposed at station B before the up-bending of the ends of the wire, and in Figs. 18 and 20 are shown a portion of the strip and the wire length after the bending operation at the same station.

In the initial movement of the carrier in its next following step to the station C the roll II of the clamp actuating rod 68 adjacent the stud I39 rides upon the opposing inclined extension 74 of the cam block 12, thus permitting the set of clamps to return to their fully open condition. They remain in this state until such roll II rides upon and is temporarily moved inward by a suitably disposed bridge-cam 939 on the adjacent frame standard. This cam bridges the proximate depending link 82 between the slotted bar SI and the side lever 83, so that when the roll escapes the bridge-cam the set of clamps resume their fully open condition, thus remaining until the roll II impinges against the inclined face 13 of the cam block I2.

The station C constitutes a wire twisting station to which the strip S with its looped wire associated therewith is advanced by the carrier. In such travel of the carrier the plates 36 adjacent the ends of the strips are gradually moved inward by the action of the stationary cams 53 on the rolls i, thus causing the inclined portions of the cam slots H of the slides to draw the complementary bars 4? and 48 toward each other. In consequence the bars simultaneously bend the basal portions of the upstanding ends of the tie wires toward each other and closely about the notched portions of the strip, as seen in Figs. 6 and 9. Hence when the strip is positioned at the station C the outwardly extending legs I of the tie wires are in close substantially parallel relation and the body of the strip is held between the closed bending bars and the backer bar 34, which latter at this period rests upon the underlying floors of the aligning recesses 33 of the respective disks.

In Fig. 21 are illustrated a portion of a strip and the tie wire having its up-standing legs inwardly bent upon the strip and extending outwardly in close relation preparatory to the twisting operation at station C.

Mounted at the station C are a series of inclined pincers corresponding in number and spaced relation with the disks 32, the jaws 94 of which pincers are arranged and adapted to receive the outwardly extending legs of the respective tie wires, and then clamp and tightly twist the basal portions of the legs which are embraced by the leading bars. The inner faces of the bars are appropriately grooved, as at 95, to permit the free twisting of the portions of the wires therebetween. The complementary members of each of the pincers are pivoted at points between their ends to the foot 96 of an inclined spindle 91 whereof the upper end has its bearings in a cross-bar 93 which is bolted to the upper rearward end portions of the respective frame standards. The jaws 94 on the lower legs 99 of the pincers are maintained normally open by means of a suitable spring, such as the hair-pin spring I00, which is secured to the foot 96, the

limbs of the spring extending to and bearing against the upper legs IUI of the pincers. These legs embrace the tapering face of a cone head I 02 slidably fitted 0n the spindle. Hence when the cone head is forcibly depressed the opposing legs ID! are spread against the action of the spring I06 in a manner to close the pincer jaws, and when such head is again raised the spring returns the jaws to their normal or open condition.

In the present instance the cone head for each of the pincers is provided with a circumferential groove I03 which slidably receives the coupling studs I04 of a bifurcated arm I05 fast on a rock shaft I06 having its bearings in forwardly extending brackets Ill! supported by the cross-bar 93. The respective end arms I05 of the series are provided with depending arms I08 having at their lower ends rolls I09 that are held in operative contact with counterpart cams II 0 on the drive shaft 21 by means of suitably-disposed springs I I I. The contour of the cams III] is such that the rock shaft I I16 and its arms are actuated to effect the closing and permit the opening of the pincers at determined intervals during the dwell of the carrier, the pincers being closed to grip the tie wires presented thereto, and being opened to release the wires after they have been twisted by a series of rotations of the pincers. In Fig. 22 are illustrated a portion of the strip and the tie-wire with its twisted projecting legs.

In the present instance the means for rotating the pincers is as follows: Fast on each of the spindles 97 is a spiral gear I I2 with which meshes a similar gear II3 fast on an upper shaft H4 which has its bearings in the respective frame standards. Mounted on the shaft IM adjacent the respective standards are pinions H5 in mesh with vertically reciprocative gear racks II6 rising from the slotted bars 86 hereinbefore referred to. Hence while the carrier is at rest, the bars 86 and gear racks IIG are vertically reciprocated. In their upward stroke the racks rotate the pinions II5 and therewith the shaft II4, which latter in turn transmits the motion through the gears H3 and II 2 to the spindles, thereby simultaneously rotating the spindles. In the downward stroke of the racks following the opening of the pincers the pincer spindles are idly rotated reversely and the pincers positioned to receive the next succeeding tie wires presented thereto.

In the next following step of the carrier the strip, with the twisted tie wires, is advanced to a station D constituting a wire folding station where the twisted wires are efficiently bent against and longitudinally of the outer face of the strip.

In the initial movement of the carrier to ad- Vance its strip from station C to station D the slide plates 36 adjacent the respective ends of the strip are moved outwardly by the action of the stationary cams 53 on the studs 50 of the plates 36 thereby effecting the opening of the wire bending bars. In this movement the bottoms of the openings 31 of the slide plates gradually approach the opposing surface of the backer bar 3d and are in contact therewith when the wire bending bars are fully opened. In the remainder of the movement the cams 53 force the slides farther outward, and as a result the bottoms of such openings 31 similarly move the backer bar and the superposed strip into the space between the open wire bending bars until the outer face of the strip is flush, or substantially so, with the outer faces of the bars. (See Figs. 6 and 10.) At this time thecarrier is at rest and the bending of the twisted legs of the wires is effected by the action thereon of a series of inclined rolls II1 which are supported for reciprocation longitudinally of the strip and in proximity to the peripheries'of the'respective disks 32. These rolls are illustrated as journalled in the bifurcated forward ends of a series of horizontal arms II8 which are secured at their rearward ends to a slide bar II9 arranged below and parallel with the drive shaft. The slide bar, which is supported I and guided in standards I on the bed 26, is provided midway of its ends with an upstanding stud roll I2I operatively fitted in the peripheral groove of a cam I22 fast on the drive shaft.- The contour of the cam groove is such that during each movement of the carrier the rolls I11 lie laterally of the paths of the legs of the respective tie wires, and during each dwell of the carrier the slidebar vIIII isshifted endwise so as to move the rolls longitudinally of the strip and against the opposing wires, thereby folding the respective legs of the wires against the strip. This done the cam I22 returns the slide bar and the rolls to'their previous positions.

. In the nextsuccee ding step of the carrier, the strip with the series of spaced tie wires applied thereto is advanced to a station E constituting a cutting station where the strip is subdivided transversely into a series of separate tags each equipped with a folded tie wire. One of the tags is shown in Fig. 23. Suitable guard bands I23 to prevent'the outward displacement of the strip in its travel are supported adjacent the ends of the carrier and in the space between the twisting and cutting stations, the lower ends of the bands be-' ing supported by posts I24 on the bed 26.

In the present instance the strip cutters comprise a series of thin circular saws I25 fast on a shaft I26 located directly beneath and longitudinally of the carrier, which shaft has its bearings inibrackets I21 on the bed. This shaft is provided with a pulley I28 which is connected by a belt I29 with the pulley I30 of a small electric motor I3I conveniently located on the bed. The teeth of the saws rotate in the path of the strip S as the carrier approaches and reaches the end of. its step, the saws being arranged in such spaced relation as to sever the strip in the spaces between the adjacent tie wires, as seen in Fig. 4, thus subdividing the strips to provide a plurality of wired tags. The outer surfaces of the wire bending bars and the backer bar are appropriately grooved, as at I32 and I33. respectively, to afford clearance for the teeth of the saws at the cutting station. The sections of the strip when they have been severed by the saws I25 are supported by and upon a plate I34 which is located under the 'car-' rier and supported by the posts I24. This plate which is slotted, as at I35, for the passage of the saws has a forwardly and downwardly deflected portion I 36 whichoverlies a suitable take-off belt I31. In the initial movement of the carrier in its step to the following station F the wired tags resting on the plate I34 are advanced until they overlie the deflected portion I36, whereupon the action of the superposed backer bar 34 on the wired tags ejects them flatwise from the carrier, and they fall upon the take-off belt, thence being transported to a suitable point of discharge.

Uponleaving station F the empty strip receiving portion of the carrier progresses to the de livery end of the magazine at station A in readiness to engage and remove the lowermost strip preparatory to a succeeding strip advancingstep of the carrier.

The use and operation of the exemplifying form of machine hereinbefore described are as follows: The magazine at station A is supplied with the preformed strips S, and the series ofwires W, drawn fromsuitable reels, are seated in the circumferential grooves 55 of the disks 32 and also in the transverse grooves 54 of the wire bending bars which are located in close relation to the delivery end of the magazine, the free ends of the wires extending upward to the effective path of the cutters and being held on the disks by the adjacent clamps 65. The motor I3I for driving the saws is energized and power is applied. to the drive shaft 21. Intermittent rotary motion is transmitted through the Geneva stop motion 'to the shaft 28 and the strip and wire carrier thereon. During each dwell of the carrier in its intermittent rotation the sets of complementary wire bending bars are located at the respective stations around the carrier, and in each step of the carrier each set is progressively advanced to the next station. The bars at the delivery end of the magazine are in open condition, the projections 53 of the trailing bar 41 abutting the opposingedge of the lowermost strip in the magazine, and the strip being supported upon the portions of the.

wires that span the gap between the two bars.

In the first step of the carrier the projections 56 of the bar 41 advance the opposing strip to station B (as seen in Figs. 6 and '7) the series of wires which underlie the strip and are clamped at their leading ends, being concurrently drawn with the strip by the carrier. During this step the clamps 65 which are gripping the leading ends of the wires are maintained in clamping relation therewith by the action of the stationary cam 12 and its temporarily held stud 89 on the end roll of the rod 68 .for actuating such clamps. As the carrier approaches the end of this step the succeeding clamps, which are now adjacent the ver-. tical path of the cutters 15, are swung over upon the disks'so as to grip the opposing wires through the action of the stationary cam 12 against the end'roll of the clamp actuating rod 68. Thus the lengths of wire between the two sets of clamps are held under tension. In the dwell of the carrier with the associated strip and tie wires at station B, the cross-head 11 is lowered by the action of the counterpart cams 88 on the side levers 83 to which thecross-head is connected, thus causing the descending cutters 15, the cam rod 9! and the presser rods 93 to act in successive order, that is to say, 1) the cutters intersect and sever the tensioned wire lengths, (2) the depending cam rod presents its recessed portion to the stud 89 and so permits sufficient outward movement of the stud and the clamp actuating rod to release the leading extremities of the wires, and (3) the presser rods impinge the underlying strip in a manner to press the strip and the mid-sections of the respective severed tie-wire lengths into and cam actuated levers 83 and their adjuncts. The.

carrier is then moved to advance the strip and the associated wires to station C. In this step the roll of the leading clamp actuating rod 68 escapes the cam l2 and the clamps which are connected with the rod are swung fully open. So also the pair of slide plates 36 adjacent the ends of the strip are moved radially inward by the action of the stationary cams 58 on the stud rolls 5| of the respective plates, thus causing the inclined portions of the cam slots 4! of the plates to force the complementary bars 4'! and 48 toward each other. In their closing movement the bars bend the opposing upstanding legs of the wires toward each other and in embracing relation to the strip, the legs thus lying in close reiation and extending outwardly from the median longitudinal line of the strip, as seen in Figs. 6, 9 and 21. When the strip and associated wires reach and dwell at the station C the legs of the wires extend between the open jaws of the pincers, whereupon such jaws, being closed by the spread-- ing of the upper legs of the pincers by the respective cone heads IE2 through the agency of the cam H0 and intermediate connections described, grip the interposed portions of the legs. Several rotations are then imparted to the respective pincers through the gearing and cam operated connections, thus twisting in the space between the pincers and the strip the respective pairs of wire legs and tightly binding the loops of the wires about the notched portions of the strip, The cone heads are then raised to permit the pincer jaws to open and release the interposed wires.

In the next step of the carrier the strip with the legs of its tie-wires extending outwardly, are advanced to the station D, thus positioning the twisted basal portions of the legs laterally of the respective folding rolls I! I. In the first part of this step the end plates 36 through which the respective ends of the backer bar 34 extend, are moved outwardly by the action of the stationary cams 53 on the rolls 5| of the plates, thus opening the wire-bending bars. In the rest of the step the bending bars remain open and the hacker bar 34, together with the strip S thereon, is pushed into the space between the proximate bending bars until the strip is flush, or substantially so, with the outer surfaces of such bars.

In the dwell of the carrier at station D the slide bar I i9 which supports the arms I I8 for the folding rolls is longitudinally reciprocated by means of the cam I22 on the drive shaft 21, which rolls closely fold and iron the legs of the wires against and longitudinally of the strip and then return to their previous positions.

The strip with its attached tie wires are next advanced to the station E and in the effective path of the teeth of the saws I25, the backer bar 34 with the wired strip thereon remaining in its outer position by virtue of the action of the stationary cams 53 on the stud rolls 5! of the end plates 35, thus serving as a rigid backer for the strips during the sawing operation. The saws sever the strip transversely at the shaped portions m of the strip, thus producing a plurality of uniform short strips to which the respective tie wires are effectually secured. The thus completed tags rest upon the underlying plate.

In the beginning of the next step of the carrier the tags as they are being advanced toward the station F are moved along the supporting plate I34 until they pass therefrom and fall upon the take-off belt E37. The bending bars remain in open condition until they progress to the delivery end of the magazine at the station A, whereupon the succession of operations hereinbefore described are repeated with respect to each succeeding lowermost strip in the magazine.
