Application led December 20, 1926. Serial No. 155,804.

rlhis invention relates to the production of shipping tags or the like, which are characterized by rhaving string-receiving openings that are reinforced by patches or washers.

The present invention discloses means whereby patches may be continuously cut from a sheet or strip of patch material, preferably being first divided into longitudinal ribbons having iiiteritting marginal undulations7 these ribbons in turn being guided to the opposite faces of a strip of tag stock and individual patches being separated from the Wstrips and applied to opposite surfaces of wetand the longitudinal ribbons passing through a suitable factor for wetting the saine7 the patches being so located upon the tags that the protuberant undulatory marginal portions thereof are locatedat either side of the string-receiving openings in order to provideasiificient amount of reinforcing' material about the same. The individual patches are preferably severed from -the longitudinal strip or ribbon alongl a straight edge'which is in substantial alignment with the edge of the tag stock, whereby the patch as applied to tiie tag may have its edge in substantial registration with the edge of the and the entire area between 'the stringreceiving opening and the adjoining edge of the ta g may be reinforced by patch material.

The above andfurther objects of the in.-

vention will become apparent to `those skilledv in the art upon a reading of the subjoined description and claims in conguiiction with the accompanying drawings, which illustrate one forni of apparatus for 13erforming the desired series of'operations.

ln the drawings, Fig. 1 is a side elevational view of the apparatus; Y

Fig. 2 is an end elevational view of the same, with parts broken away and parts shown in section;

Fig. 3 is an elevational side View of the patchffeed mechanism andthe die which cooperates therewith;

Fig. l is a top view of similar mechanism;

Fig. 5 isa detailed elevational View;

Fig. 6 assembly; Y f

Fig. VZ is a section online 6 6 of Fig'. k5 showing the die members `mutually apyproached;

Fig. 8 isa similar'vie'w showing the same spaced apart; and y Fig. 9 isa plan View of a porti-on of the patch'stoclr, the dot and dash lines showing the way the separate patches are cut from the same.

While the accompanying drawings illus-l trate one ,form of apparatus which is adapted continuously to receive'strips of patch material and tag stock to form the patches and to apply the same to the tags while forming string-receiving openings in the superimposed patches and tags, it is to be understood l is an elevational view of the die that this concrete embodiment of the apparatus is merely shown for purposes of illustration and the steps, and operations occurring in conjunction with this method and apparatus need not exactly coincide with the illustrated method nor occur continuously as shown.

Referring more particularly to Figs. and- 2, the patchnstock 7, which is vpreferably gummed,' may be received in a continuous numeral L and comprising a series of' disks with undulated peripheries adapted to rotate in closejuxtapositio'n to a plain roller in orderto cut the strip of Vpatch material intoy longitudinal ribbons,v edge' portions of which are provided with undulations which are adapted substantially to interfit, The ribbons asthus lcut are directed in any suitable manner to 'a moistening factor 10 which is adapted to render the gum or mucilaginous readily adhesive.

substanceV upon one surfaceofthe ribbon The ribbon is then drawn tothe guidev element lwhich isv adapted to guide'onel stripl of ribbon in a lpath above andparallel f 210.5.

to the path of the other strip, the lower strip being twisted so that its moistene'd face is eob vstrip from the reel 1, passing under and over suitable guide members 3 and 2 respectively to a cutter of the'type Yhaving disks with wavy or Zig-Zag edges, indicated byv the.

- may be connected by suitable linkage to the Vlever 27 which is adapted to reciprocate the and the corresponding apparatus, it is to be understood that the guiding mechanism 13 comprises superimposed plates having Vchanl nels lil, designated by dotted lines (F ig. 3), which are adapted to receive the ribbons of patch material above each other.

Preferably the patch ribbons are moved in synchronized relation with the movement of the tag stock itself, this movement being impartedY by means of a shaft 2O having suitable eccentrics 21, 22 and 23v for driving various parts of the mechanism in synchronized relation. As shown, the eccentric 22 patchefeeding mechanism through link 2,8.

V"This patchfeeding mechanism preferably comprises a frame 39 slidable on guide element 13 kand having oppositely disposed diagonal fingers 29, juxtaposed ends of which are shaped to engage the undulated marginal portions of the patch ribbon and which are normally drawn towards each other by a spring 30. Reciprocation of the feeding mechanism results in the Vpinching of the margins of the ribbon by the ends of the fingers 29 and reciprocating movement of these lingers results in feeding of the patch material toward the die. In order to hold the patch material in advanced position in the manner indicated, suitable retention iing gers 33, which correspond somewhat indimensions and relation to each other with the arrangement of members 29 (Fig. 5), are supported upon the members 13, being -drawn toward each other by spring 32.

Any suitable guides 31 may extend from this portion of the mechanism towards the die assembly indicated in general by numeral 40. ThusA the ribbon is advanced by fingers 29 which grip the same, but lingers 335engage reentrant marginal portions of `the strip to retain it in advanced position,

being forced intomore firmV gripping relation with the saine by tendency of the strip to move backward when the motion of carrier 13 and fingers 29 is reversed, while retraction ofthe member 39 andthe angularity of lingers 29 cause them to be spread apart and the spring v to lbe expanded by the cam-like bearing of the former upon the curved marginal surfaces of the patch ribbon. l

The die assembly preferably comprises upperrand low-er die elements il and l2 respectively igs.l 41- and 5) and an intermediate fiXed guide piece 33 with related parts. Preferably this' guide piece is provided with suitableV slots for receiving the -paralflel ribbons of patch stock, desigi nated by numeral 63, and' is provided with suitable slots 34 for guiding the tag stock 50 in a plane parallel to and spaced between the planes of the patch ribbons. Above the plane of slots 34: is the die member l1 which is adapted to have an edge 62 pass downwardly in close alignment with the edge of the tag stock while die 42 has asimilar upward movement, The plate 37 projects from the mid portion of bracket and is adapted to cooperate `with the dies to sever or shear the individual patches from the patch strips. The die il is also provided with an intermediate plunger 43, which may be projected below the plane of the rest of the upper die. Preferably the die elements are operated by the eccentric mechanism previously referredto through suitable connecting rods i5 and l? respectively (Fig. 2), while the plunger is actuated through cam 23, being provided with a spring 57 normally to hold it up.

The die elements are thus preferably brought into juxtaposed relation, being spaced apart vat a distance (Fig. 7) which will permit their plane surfacestopress the patches into adhesive engagement with the tag lwithout objectionally crushing the same, while the plunger i3 is driven downward for a sufficientdistance to cutsmall disks` out of 'the superimposed patches and tags, these disks dropping from the machine through the bore i9 in the lower die. Thus between each step-by-step movement, flat adjoining surfaces of the die elements are adapted to press a'gummed patch upon each ofthe opposite faces of a tag element,r subsequentlyto the severing of the individual patches from the ribbons of patch material, and concomitantly with the cutting of the string-receiving openings in patch and tag `material. may be separated from the tag stock in any suitable manner.

j If desired, the original strip or sheet of patch material may be wider than shown and a sufiicient number of patch ribbons 110 may be cut by a single cutter having an appropriate number of disks to supply several patch-applying machines; it being under-y stood that in case the patch stockis slit in Y the samccontinuous operation with the 115 application of the patches to the tags asV i shown, for illustration, thecutter is driven at a speed proportional to that of the main shaft 2O by any suitable means. Y Y It is thus evident that a continuous 120 method `of making Vtags with adhesively of the patches to the tag may be accom 130 Subsequently the individual tags plislied in a single operation and in'synchronized relation with the cutting of the longitudinal ribbons so that 'production of tags of this type may take place with high etliciency and at nominal cost.
