pletedbox flange; andFig, 9 is a detail of the dauber shaft andbeari-ngsls f' ",As tending to a more ready unde' ing of this invention, reference isxltiere to my now pending application, Seria No 492,029, filed April 24-,-1909,,Wherein if closed a machine and method forthe duction of a box, consisting "substan 1a of. afiat head or body, a marginal flangegeir tending around the edge of the headafi but if desired, other terials may be used. Referring tofth'e flange, towhich, in, the present 'sp'ecifi bodiment, this invention more particul relates, it will be seen to consistoffa ;s 1p. 1. having a central section 1, two intermed e 0. its central section and two end section '3 transverse front scores or grooves 51,14 lb tween the centralsection and the ,mtermef tivelv, and the ends of-the flange are.

eled to form scarfs, as shown a outer'side thereof. In its. completed, ;fo the scarfed portions of the endsectio the flange overlap one anotherland united by paste, cement, 'glue, or ene a;-

hesive which will answer the purpose, andiQO each groove or score are folded ,towardge other in bending the sections of the flange t form a corner, thereby causing the outer, s1 of the corner to be sharp and square should be noted'that the said groove is preferably formed with" straigh proximately in contact withteaclf QtbQl'e-thu I i suhstantiallyclosing th I et ,el) 1t isalso ,to be/n'oted the to form the grooves,

the material, from which the flange is made it will be found that, when the sections of the flange are bent to form the corners thereof, there willbe an excess of material, HHS- ing blisters or wrinkles in the material=and uneven corners.

In carrying out the present art, scores or grooves are formed by abrading the web to positively removematerial therefrom, preferably by means of suitable grinding mechanism, thereby insuring smooth. square corners on the complete flange. It is to l i also noted that byforming scarfs on the flanges on opposite sidesof the ends thereof the said ends may be neatly and effectively joined together and the flange will have the same thickness of material at the joint as throughout the other portions thereof. It is worthy of note that when anattempt is made to secure the adherence of two surfaces, as the SC'M'fQll ends described herein, by application of glue thereto. immediately before the surfaced zire lapped one over the other, that the same do not reliably stick to each othe' and that this'dillieulty is oven come by applying the glue to these scart'ed edges for a sufficient length of time before the scarfed joint is formed to enable the glue, to become partly dried or tacky. This (ifficnlty is overcome iii carrying out the prisent art by coating one of the scarfed edge. of the web with glue a suliiciently long time before it is desired to complete the flange to en-able the glue to become dry, or nearly so, whereby this preliminary gluing operates as a sizing and :auses said edge to become firmly united with the other seal-fed edge of theflange blank when the two are subsequently brought together, glue being applied to said other edge just beforedhc two are brought together, so that it will be-sulliciently moist to permit of a reliable joint between the ends of the flange blank. [t is to be understood, liowerelgtlmt the present invention relates specifically to the treatment of the web, feedin scoring, trimming,

scarfing and the application ofjglue to one of its scarfed edges, and that no claim is herein made to the subsequent severing of the flange blanks and their utilization in forming a box. Although various means may be employed for scoring and snarling the flange web and,performing the various other steps hereip desrribed in. relatirm to the present art, it is rueferred to use for this purpose the meeluuusm which is shown in the accompanying drawingsand which is.

construetml as follows: I

T representsiafhorizontal arbor, shaft or mandrel wh ch is pmrnaled transversely on the frame of tlnrmaehine and upon which is mounted a roll i! ofllange web. From this roll the flange web is unwound from the rear side thereof and with its inner 015' front Sit e over the rear asses upwardly side of a support 10 which is constructed as an upright plate formed on the fame S.

The flange web may be propelled upwardly along this supporting plate or table by various means, but, preferably, by means of two feed rollers 11, 11 mgaging with opposite sides of the central part thereof and 'mounted on transverse shafts 12, 12 which are journaled in suitable hearings on the rear part of the frame. These feed rollers are compelled to turn in unison by means of intermeshing g ar wheels '1 1 secured to rorresmanding ends thereof. as shown in Figs. 1. 2 and -l. and motion is transmitted to these feed rollers from an overhead driving shaft 14 by means of a counter shaft .15 provided with a pinion It at one end which meshes with a gear wheel 17 on one of the feed roller shafts 12. and a belt 18 passing around tight and loose pulleys 15), 20 on 'the counter shaft and a pulley 21 on the driving shaft.

in order to prevent the roll of flange web from unwinding too freely. a retarding or dunking device is provided which preferably consists of one or more brake bands or straps 22 engaging with the front side of the roll of flange web and eonnerted at their upper ends with the adjacent part of the frame while their lower-ends are provided with weights :2 whereby these straps or hands are held 'l'rirtionally in eontai-t with the llange web roll and prevent turning thereof. except when the web is unwound therefrrnn by the action of the feed ltllltllS to the action of the devices which produce the outer or rear longitudinal scores-'3, then to the devires which produc-e the inner or front longitudinal scores -I. l. and then to the devices which pl'mllu'e the searfs (i. U at the opposite edges thereof.

The scoring devices whereby the longi tudinal scores or grooves are produced in the flange web preferably comprise a plurality of rotatable scoring wheelsor disks iii-b21127) which are roustrm-ted of emery. wirlmrl'unluru or other abrasive material and each of which is provided with a comparzr tively narrow peripheral edge. of convex or beveled form in'eross section. so that upon engaging the "rear or outer side of the flange web-a groove or score will be ground or cut in the little as the same isinoved past the seoring wheel, which groove is formed by particles abovh opening in the slide 40 and journaled on the islide 42 so as to be held against axialmove mcnt, wherebyupon turnmg this screw the respective grinding wheel will be moved toward or from the flat face of the web. The transverse movement of the slide 42 in its way 13 is eli'ectcd by hand pressure and after adjustment the same is held in place by tightening one side 45 of this guideway which for this purpose is made separate from the frame and secured thereto by a clamping screw -16.

As the flange web passes upwardly beyond the scat-ling devices the same is subjected to the action of a cleaning or a clearing device which operates to detach thercfrom the particles of dust or fiber which havebecn ground oil from the web by the action of thescoring and one of the searfing wheels but still remain stickingor adhering thereto. consists of a rotatable brush 4T horizontally supported in suitable bearings 48 in a position parallel to the web and disposed to sweep the rear or outer side thereof at a point above tlte scarling wheels. The bristics thereom which are preferably arranged in longitiulinally extending sinuous lines, clear said rear side of the web and the scores and rear scat-led edge thereof, of the mentioned. short brush, not shownfeither rotatable or stationary, may be secured to the front side of the support for removing adhering particles on the corresponding scarfed edge of the web. The brush 4? is drivenby means of a belt l9 passingaround a pulley 50 secured upon the sha'l'tlfi and the pulley 51, fastened to the brush shaft 52.

Means are provided for collecting the particles of stock or fiber. which are removed from the flange web in thelorm of dust by the scoring and scat-ling wheels, in order to prevent the same from collecting in the machine and interfering with its operati on and i also vitiating ii i air in the roomin which the machine is installcdf For this purpose a hood 53 is hinged to the supporting plate 10 at; 54- and extends outwardly and downwardly, completely covering the various web operating means hereinhelore described, and

resting at; its lower from the rear side of bent inwardly into. close said support, uportions moved for thetpassage'thcrethrongh ofthe on the adjacent part of i is adjusted on i is delivered deseribcrlabove.

This clearing device preferably If desired, a i

which is free thereof. The web is held in IllilffB various shafts disposed upon the outer side of the support. The sides of the hood are also cut away as at 56 to provide openings through which the web trimmings are discharged from the machine. An opening 5? indie plate 555 communicates by means of a down tube 58 with an exhaust pipe 59, from which the air isexhausted and the dust discharged in any convenient manner, but preferably by means of a fan 60 connected with the exhaust pipe, and iflischarging at any convenient place. As the tan operates the dust resulting from the grinding action of the scarfing and scoring wheels in forming the scarfs and grooves in the flange web is drawn through the space inclosed by the hood and exhaust pipe into the fan case and The blades of the fan may be rotated in any suitable manner, for instance by means of a belt (31 passing around suitable pulleys on the driving and fan. shafts.

Altcr the web has been operated upon by the brush it passes to the device for sizing the front scarfed edge. as hcrcinbcforc de scribed. This gluing or slicing dcdrc is preferably located on the frame above the clearing brush and is constructed as :lollows: 62 indicates a tank or pot arranged upon the upper part of the frame the front scart'cd edge of the flange is designed to contain a bath of liquid glue, which is retained in a liuid condition by a heating device. preferably consisting of a jacket (SI-5 arranged below the tank and through which a heating medium is cit-cw latcd. such as hot water or steam. Above this tank is arranged a horim'intal trans verse shaft (ll supported in suitable bearings ti? on the adjacent part of the machine and carrying a paste wheel or dauber 6G to turn on its shaft; with the lower portion thereof submerged in. the glue contained in said pot. The journals (3'? of the shaft are formed eccentric with the wheel carrying portion thereof, and a. crank 68 rigidly sciiurcd thereto is constantly acted upon by the springlll) to hold the periphery oi the pasting wheel in operative relation to the t'lange wcb. which passes rearwardly while the pasting wheel ordauber is engaging the foradjacent ward scar'led edge thereof by means of a fiber of the web and becomes and. merely acts as a sizing for subsei'piently insuring its firm adhesion to the front seal-fed edge when the la;

web and .scarfml'edge of the web picks up glue and deposits the same upon theweb.
