METHOD OF' AND APPARATUS FOR ACTIVATING LABELS Filed Jan. 18, 1950 wwf if LLA TTV.
Petenta oef. 1, i952 UNITED STATES tn New wiiereiii uie'vi tiiereeil ieieiiilveiil e trolling a waive 3B provlided ion La :pipe Macommunicating "with Aa source of `hot air or steam. Connected-to pipe-Mis a'nozzle14l arrangedito direct thehot-airor steam passing through valve 3B `upon a label carried by drum B. The formationlof -nozzlel'lis such that the hot blast of air orstearndelivered thereby will progressivelyand entirely `subject an area of thedrum `B 'on `which af label is mounted, to '-heat `for a predetermined period of time during the rotational movement of thefdrum.` The period of time `that the hot air blast for =steam is directed against fa label 'mountedlonfthe 'drumfisfcontrolledlbythe length of time that the roller 3B is'in engagement with la portion offthe cam *Mintermediatethe raisedportio'ns 35 thereof.` When the `roller 35'comes linto engagemerit with the outer `edgefof a raised portion 35 of thecamfthe `linl: mechanism 3B will operate valvef39`to-cut off the flow of hot air or steam to the nozzle 4i on pipe l0, and =Wlll maintain such `valve shut during rtheperiod of engagement of roller 36 with such outer Aedge-of `raised cam por- -tion 35. l
- In the `event the machine shutsdown, thevalv may bemanually manipulated to` shut yoff the hot air-or `st'earn or-an interlock `may beprovided for 'such purpose. As is shown in'Fig. 2 ofthe drawings, `such an linterlock'may be composed of anar-m 45 fixed toarm 31 so as `-to rotate therewithyas `the 'roller 36 moves along the cam '34. The outer end of arm 45 is positionedadjacent to the outer end'of `a lever 46 whenthe `cam roller 36 is engaging'a portion of the cam intermediate the `raised portions 35 of such cam, and moves in `a `rrloclrwise direction, `as `viewed in Fig. 2, away from lever 46 "as the roller 36 `travels up "a sucneeding raised portion 35. During the ltravel of the-roller l36 from 'the outer or high Aedge vof a raised portion 35 to a cam portion intermediate -suchraised portions, theouter end of arm 45'will 4rotate Aina counter-clockwise direction toa position adjacent to the outer end of lever `46 `(note Fig. 12), and 'will remain in such position while #the roller is in vengagement with lsuch intermediate portion. The vlever 451s mounted ona shaft #'41 `to `rotate in the same plane as arm -4'5 and is connected through such 'shaft to "suitable clutch mechanism (not shown) Aarranged and constructed to rotate-shafi'ffl andconsequently lever 451m -a` counter-clockwise'direction `as lindicated by the arrow'w-hen the `machine is shut down. "Ihe amount of rcounter-ciockwse rotation of lever46 is such that whether roller 36,at the time Vof such shutdown, -is 'in engagement `with Aeither 4a raised o'r "intermediate-portion -of cam 34, the outer end Aof 'lever 46 will `engage arm 45 and rotate the latter in -a clockwise direction as to move the roller 436 -outwardly beyond the outer or `high edgesof vthe raised` portions 35 of cam 34, and thereby operating valve 39 to `prevent the passage of hot-air or steam "through the nozzle 4l.
In order to immediatelycoola label `which has Abeen subjected to ablast of 4hot `air or steam, cool air is blown against it soon after such label has :moved past the nozzle 4l in "the Arotativeimovement `of the drum '13. The lcoolair is directed against the label byfa'lnozzlel located approxi-` mately the length of aiabel -in advance of nozzle -4`I and connected `to `a 1source of continuous cool air-supply.
l From the foregoing, itwil-l be understood that *the `pick-up cylinder `IHl of `the label transfer mechanism engages nindividual rlabels from the lstack Gand transfers them in rapidsuccession to rdrumB. -As each =labe`l -is delivered to drum B,
itis abutted ilrmlyfagainstfoxiemf thepositioning ribs 3| and is "retained in :this 'position nnfthe causing lthe latter to actuate '.thewalve `control mechanism ito :openvalve 395. Uponvthe `opening of valve 39, a'blast `of ,hotfair''or steam fhav'ingfa temperature of approximately 1450 degrees is delivered by nozzle 4l `upon .the label. Thetarrangement and construction 'of the mechanismL-is irs `nozzle 4l. blast, the adhesive .coating 1:4 of thelabellissubsuch that .the hot fair Ablast nor :steam is directed against the peripheryof drum B justapriorto the passage of lthe'label .through thearea :covered-:by such blast. As the label passes 4into such area, the protective rib `or rguardyl will `prevent the leading edge of the labelzfrom being-picked lupl'by the blast. `As thellabel passesthroughthisarea of hightemperature air `or steam, the thermoplastic adhesive coating I4 thereof, will become, `advl'iesively actvatedin aprogressive uniform. man-` ner. 4After the label `.passes throughthe region of hot air or steam, it is subjected `to acooling :blast ofair from the succeeding rcnl'dzairinozzle "481. The activated label is then applied .iat station .Altman varticle passing thereby :in `the manner previously described.
It will thus be seen'that in accordancewith th present invention, the `laminatedsheets rorl'abels are fed from stack C tothe labelapplyingstation A by means of a cylinder 3U which is `at room temperature land drum B whichis maintained at room temperature for slightly cooler, .due to rthe cooling liquid .circulating therethrough. Thus.
'body results from such handling of thelabel.` The lapplication of the hot air or steam blast, whileit would tend to distort the label and even ydestroy the inks and varnishes` on the label if the latter `were subjected to it for any appreciable length `of time, is only eiective on each portion :of `the adhesive coating I4 just long-enough to activate -each such portion. Thehot air-or steam 4blast is in effect moved over the adhesive coating I4 of the label in a sweeping manner so that it :affects vonly such coating and does not substantially penetrate to the underlying "layers `of the `label. When steam is used, especially in thelcase oflaminated foil labels, sufcient'moisture is 'introduced `into the paper of the label to cause the latter to expand to an extent as to -minimizestressesin the label as has been explained. The amount 4of moisture introduced into the labelcan be controlled by controlling the composition of lthe steam and its supply through `the `valve 39 and Almost immediately after such hot jected to the cooling air blast frominozzle Bto reduceV it to roomv temperature and so that the heat in such coating is not substantially transferred to the laminated body of the label, thereby avoiding possibility of distortion of the label upon its release at the label applying station A. The minor portion of heat that may reach the body of the label from its heated adhesive coating I4 prior to the cooling blast, is not great enough to create suicient stresses therein to overcome the force exerted by the vacuum holding the sheet against the cylinder Wall. These stresses however, are of suicient magnitude to distort a freely supported label or sheetof laminated material. cordingly, it is importantY that the entire laminated body and adhesive coating of the label be brought to room temperature prior to the release of the label from drum B. Even though the adhesive coating-i4 of the label is cooled to room temperature prior to its complete attachment to the article by the belt 25 and rail 26, it will remain usefully adhesive until such means completes its attachment to the article.
While I have herein described and illustrated a preferred embodiment of the invention, it will be readily apparent to those skilled in the art that various modifications andchanges may be made therein Without departing from the spirit of the invention. Thus, a radiant heating means capable of producing directed heat Waves within a predetermined area may be substituted for nozzle 4l. In such construction, the valve 39 will be replaced by suitable switch means operable under the control of the previously described members 34, 35, 36, 31 and 38. It will thus be understood that I intend to include Within the scope of the invention, al1 embodiments of the invention coming within the terms of the appended claims,
