This invention is for improvements in 01 mounted on an endless conveyor 4 and arrelating to machinery for applyinglabelsto ranged to-automatic-ally move the box along packages, and more particularly to a machine the bed 5 of themachine' and into engageadapted to fold a label of paper about a ment withaweb ofpaper 6.

The box is then raised intofa. stacker 15 Fig. 7 shows a third method of folding a in the manner shown in'Figs. 2 and 3, and label around a box. the free endof the strip is folded downward- Figure 8 is a. diagrammatic illustration of ly so as to leave a portion protruding from a gum supplying device applicable to the the underside of the box, whereupon the next arrangement shown in Figure 5 of the drawoncoming box folds the protruding strip on ings.

plicable to the arrangement disclosed in In the modified form of folding shown in Fi 7, and I 7 Figs. 5 and 6, the box is arranged to meet Figure 10 illustrates asheet feeding mechathelabel-at about mid-way of its length so nism for carrying out the'labeling method that the label is formed into a shape with described herein, in the event that separate two over hanging portions at the rear of the sheets rather than a continuous web of labelpackage as shown in Fig. 5. When the packiing material issupplied. age reaches. the verticalstacker the bottom Referring to Fig. 1, a series ofboxesfl are overlapping flap is folded upwardly by an arranged in a vertical magazine 2 in such'a oscillating tucker 16, which may, necesmanner that the lowermost box is removed isary, apply gum to the flap, and the top flap is 60 from the magazine by a pusher. piece 3 folded down over the lower one as'the pacle loo age is pushed upwardly into the stacker 15.

One arrangement by means of which gum may be supplied to the tucker 16 is shown in Figure 8 of the drawings. It will be observed from this figure that a lever 16d carrying a gum applying roller 16a is oscillated by means of a cam 166 and the two cams shown in this figure are rotated in timed re; lation so that gum is supplied to the tucker 16 while it occupies a lower position away from the ackage. I

In anot er way of carrying the invention into effect, the package is arranged to meet the web of material immediately. after the latter commences to pass through the slot in the bed of the machine, and the long overhanging strip which is produced, is folded by rotating the package through a semi-circle during which motion the long flap is folded around the box. An apparatus for this purpose is shown in Fig. 7 and on reference to that figure it will be seen that after the folding operation the package is moved into a compartment 17 formed in a rotary member 18, and when the package has reached the position shown in Fig. 7 the member 18 is rotated through a semi-circle, during which movement theover hanging fiap is bent down by a plate 19. The member 18 may be rotated intermittently by any of the various types of mechanical movements commonly used for such a purpose. One such arrangement is illustrated in Figure 9 of the draw ings in which the shaft 18h on which the member 18 is mounted carries a gear 18a which is in turn driven by a gear 186. The latter gear is formed integrally with or is secured to a slotted disc'180. A. second disc l8e carries a roller 18d which is arranged to engage in the slots formed in the plate 180 so that on each rotation of the disc 186 the slotted disc 180 will be rotated through approximately 60. The disc 186 is preferably provided with a cam shaped periphery having a cam rise at the point 18;". A roller 18?? carried on a lever 18g is urged into contact with the periphery of the disc 18e by means of a spring 187' having one end attached to the lever and the other end to any convenient portion of the machine. A second roller 18% carried at one end of the lever 18g is thus caused to engage and disengage with the slots in the plate 180, thus locking the plate against rotation when it is not being positively driven by the roller 18d: It will be observed that the cam rise 18; is so positioned with relation to the roller 18d that one of these rollers is withdrawn from the slotted plate 180 as the'other roller moves into engagement with the plate.

When the package reaches the upper position it is removed from the compartment by a pusher 20 carried on a continuous con- 'veyor 21, and durlng this movement the long flap 1s folded smoothly down upon the packwrap a printed label around a box of cigarettes or like package.

It will be appreciated that instead of the web of paper being printed as it is fed through the machine, the same may be preprinted and provided with suitable holes whereby the pre-printed web may be fed into the path of the boxes, or if necessary, cut sheets may be fed from a magazine.

One form of mechanism suitable for feeding cutsheets is illustrated in Figure 10 of the drawings. Inthis figure the sheets 23 are shown asstacked in a magazine 24 and an oscillating suction tube 25 pivoted at 26 serves to pull the forward end of the sheets downwardly, one at a time. The suction tube may be oscillated in any convenient manner, for instance by means of the lever 27 and link 28 from asuitable cam, not shown.

A roiler29 is carried on a lever 3O which is integral with the lever 27", the arrangement being such that as the front edge of the sheet is pulled downwardly onto a continuously rotating roller 31 the roller 29 rocks into contact with the upper surface of the 'blank which is then fed by the roller 31 into engagement with the rollers 32. V v

I A cooperating roller 33 deflects the sheet vertically downwardsthrough guides 34 and the bed slot 35. Asupport roller 36 serves to carry the forward ends of the sheets.
