MACHINE FOR APPLYING BANDS OR STAMPS TO PACKETS Filed July 5, 1932 2 Sheets-Sheet 2 MW BJ MM AW Patented Dec. 12, 1933 PATENT OFFICE MACHINE roe APPLYING BANDS on STAMPS TO PACKETS James Mason, Deptford, London, England Application July 5, 1932, Serial No. 620,929, and

a in Great Britain July 13, 1931 16 Claims. (Cl. 216-55) This invention relates to .a machine wherein bands, stamps or the like are automatically wrapped around packets, for example, packets of cigarettes, and hasfor its object the'provision I :of .a machine wherein stamps maybe applied to the packets at a greater speedand more efficiently than has hitherto beenpossible.

The invention consists of an apparatus for applying bands, stamps or the like to packets which comprises a rotary suction device arranged to move past a magazine and remove a stamp therefrom and carry the same past a gumming device and thereafter deliver the stamp to a device which holds it across the path of a packet carried continuously along by a conveyor or the like.

The invention will be more particularly described with reference to the accompanying drawings, in which:-- i

Fig. 1 is a diagrammatic sectional elevation of a machine constructed according to the invention. 1

Fig. 2 is an enlarged view of a portion of Fig. 1. Fig. 3 is a plan of Fig.2. i Fig.4 is 'a perspective view of a packet having s a stamp applied thereto.

Fig. 5 is an end elevation of a movable stamp holder. V

Fig. 6 is a plan of a tucking device for the trailing ends of a stamp. -Referring to'the drawings, the packets 1 are placed in a magazine 2 and removed therefrom one at a time by pusher pieces 3 carried on a continuous conveyor 4. The pusher pieces carry thepacketsthrough guides 5 at the endof which 33 :.a stamp holding mechanism 6 is arranged. The stamps are stacked in a pile in a magazine 7 which is pivoted on a bearing bracket 8 above the bed of the-machine and they are removed from the bottom of the pile one at a time by a rotating -suction apparatus 9- The suction apparatus is mounted on pivots 10 and consists of two pairs of hollow members 1 1 and 12 mounted on a central hub 13, the pairs of i suct'ion members being disposed at diametrically of the stamps so that ungummed portions are swings on its pivot 27 and moves out of the way curely take hold of the stamp, the magazine which is pivoted atits upperend to the bracket. 8 is oscillated'by a cam 15and spring 16 so that the lowermost stamp. in the magazine moves in contact with the suction members for a short 6 distance beioreit is removed from the magazine. The outlet of the magazine is preferably provided with. a spring guardor'finger '7 which prevents more than one stamp from being removed at a time.

The suction members carry the stamp past a gum roller 17 which may have a series of ribs to apply the gum in streaks, the roller receiving itsJ gum from a gum feeding mechanism 18 in the usual. manner.

The stamp holding mechanism consists of two parts 6 which are arranged on the machine bed at either side of the conveyor. The stamp is stripped from the suckers by prongs 19 and retained in position against stops 19 until an oncoming packet contacts with it.

The suction members have grooves 20 formed in their faces to give clearance to the prongs 19 and preferably the gum is applied to the ends left where the prongs 19 will touch the stamp.

The stamp holders 6 have pivoted members 22 pressed by springs 23 and the stamp is lightly gripped between the'members ZZand prongs 19 so that as the packet pulls the stamp from the stamp holders it is under a certain amount of tension and is pulledtaut across the leading face of the packet and around the two side faces asshown, in Fig. 4. In order to permit thestampto enter the gripper formed by prongs 19 and member 22; the latter' are pressed back against spring tension by projections 9 :striking the members '22 as shown in Fig-3.

The packet is then carried betweena pair of guides 24 which firmly press the side extensions of the stamp on to the side'faces of the packet so that the stamp is neatly and securely attached to the packet; the guides being heated as usual if desired.

As shown in Fig. 1, the conveyor 4 finishes shortly after the stamp applying position 'and the packets are moved further alongthe guides by rotary pawls 25. s

In an alternative form the stamp 'may be'ap plied only to one face of the packet, in which as the'packet continues its movement.

The pivoted holder is operated by a cam 28 and spring 29, the lever 26 being furnished with a cam roller 30.

It will be understood that instead of having 5 the cam, the lever 26 may be held in the position shown in full lines by a spring of such strength that the pressure of the packet when moved by the conveyor will cause the holder- 25 to be pushed out of the way without injury to the packet. V

This form of the invention is particularly useful where a small stamp is to be placed on a packet, in which case only half of the suction apparatus is required, the particular suction case being made approximately the same size as the stamp.

Further, the stamp may be wrapped around the four sides of the packet with the ends overlapping by mechanism such as is shown in Figure 6.

' Referring to that figure, two folders or tuckers 31 are provided pivoted to the ends of levers 32" ment by means of guide blocks 35 and springs 36, the tuckers working one after the other by suitably displacing the two cams 34. The'springs 35 pleted. r 7
