Abstract: 778,049. Making cartons. PACKAGE MACHINERY CO. Nov, 10, 1954 [Nov. 17, 1953], No. 32563/54. Class 18. [Also in Group XVI] In a machine for assembling a carton of the kind described in Specification 720,815, handle blanks 10 are fed to mandrels 13 on a rotating turret 14 at a station A, Fig. 1, the blanks 10 being drawn into the mandrels and carried to a station B where erected sleeves 11 are fitted into the mandrel, then to a station C where shell blanks 12 are folded round the blanks 10, 11 within the mandrel, and past devices for pressing the glued joints located at stations C, D and E to ejecting station F. The blanks 10, Fig. 85, are fed from a magazine 18, Figs. 1, 5, 10 by elements 21, 22 (see Group XVI) on rotating discs 25 to plates 34, 35, the trailing end of a blank being engaged by pushers 29 to force it between the plates and against stops 48 (shown withdrawn). The plate 34 is vertically moveable and descends to clamp the blank against the plate 35 while folders 52, 53 and 75, Figs. 5, 10, fold upwardly the tabs d and e respectively. The plate 34 rises and a shaft 49 rotates to raise the stops 48 to the position of Fig. 5 and cause pushers 51 to engage in the handle aperture of the blank 10 to force the blank between springs 95 carried on a mandrel 13. Pins 97, Figs. 5, 17, 19, pivoted on a bar 96 mounted in the mandrel, engage the handle aperture c and the bar 96 slides down slots 100 to draw the blank 10 into the mandrel. The bar 96 is operated by radial sliders 423 in guideways 414, Figs. 4, 17, engaging rollers 103 on the bar. The mandrel is then indexed to position B to receive the sleeve 11. The collapsed sleeves 11, Fig. 86, are each fed from a magazine 16, Figs. 1, 24, 31, by a reciprocating pusher 125 against a stop 123 where pivoted arms 129 set them up to tubular form. Plungers 140 advance through opposed walls of the sleeve to open out tabs g and a pusher plate 150 forces the sleeve into slots 148 in a mandrel 13 and into assembled relation with slots a of the handle blank already in the mandrel. Shell blanks 12, Fig. 87, are moved singly (as described in Specification 778,050 [Group II] from a stack in a magazine 17 to folders 329, 330, Figs. 1, 50, 52, which break the creases of the flaps j and fold the flaps i onto the panel A presser plate 842 clamps the panel m and the folders 329 swing the flaps j upwardly against spring hinged plates 1082. As the folders 329 withdraw, the plates 1082 return the flaps j to the full line position of Fig. 52. The folders 330 are similar to the folders 329 and press the flaps i onto the panel l after which a presser 308 descends to consolidate the folds. The blank is forwarded past glue applying means which apply glue lines y, y<SP>1</SP> to panels k, m, lines x to flaps h and lines to the margins of the underside of flaps j, Fig. 66, to rest on a platform 337 beneath the mandrel 13 at position C, Figs. 1, 66, 71, 72, flaps i being held in place by bars 754 and pivoted fingers 722 until the platform 337 rises to clamp them beneath the mandrel. Upward movement of a yoke 340 causes plates 266, 267 to hinge upwardly to fold panels k and m against the mandrel. Fingers 344 and sweeps 1078 fold in the flaps j so that they lie beneath tabs d of handle blank 10 within the mandrel, flaps h and tabs n, when there are folded against the mandrel by members 241, carried on arms 256, Fig. 1, and fingers 503 respectively. The carton is now completely assembled on the mandrel. The tabs n, and therefore fingers 503, are optional. The members 241, when aligned with the vertical side seams of the carton are forced inwardly by toggles (not shown) so that their rubber facings press the seam against the mandrel to consolidate the joint. As the mandrel moves from station C to station D, the arms 256 swing with it so that the members 241 remain in contact with the seams over a portion of the travel. At station D, pressers 402, 403, Fig. 80, swing against the mandrel sides to consolidate the joint between panels k, m, and the sleeve 11 at glue lines y, y<SP>1</SP>, and further pressers 241<SP>1</SP> press the side seams. At station E pressers 241<SP>11</SP> engage the side seams. The completed carton is ejected at station F by the rollers 103 on the bars 96, Figs. 4, 17, being engaged by radial sliders 424 which raise the bars to their handle receiving portion of station A. The rollers 103 are then aligned with tracks 680 and are guided by them onto the sliders 423 at station A. The cartons are tipped by bars 1121 on rotating discs 1124, Fig. 1, outo a conveyer shoot for discharge from the machine. All non-rotating parts of the machine are cam operated and all rotating shafts are chain driven from a single motor M.
