MACHINE FOR MANUFACTURING PACKETS, FOR PACKING CIGABETTES 0B OTHE MATTERS.

Application filed July 7,

To all whom it may concern:

Be it known that we, GUNNAR CHRISTIAN EKSTRiiM, a subject of the King of Sweden, and resident of Eriksbergsgatan 14, Stockholm, in the Kingdom of Sweden, and GUS- TAF ORsTRGM, a subject of the King of Sweden, and resident of Palsundsgatan 6, Stockholm, in the Kingdom of Sweden, have invented certain new and useful Improvements in Machines for Manufacturing Packets, for Packingicigarettes or Other Matters, of which t e following is a specification, reference being had therein to the accompanying drawing.

For packing cigarettes or other matters double capsules, packets, boxes or the like sometimes are used, the inner capsule or lining being generally of tinfoil. This invention relates to an arrangement in machines specially of the, type, stated in the U. S. Letters Patent No. 1,379,254, by means of which the said machines may make also double packets etc.

In the accompanying drawing Figs. 1 and 2 show diagrammatically so much of a machine arranged in accordance with this invention, as is necessary to explain the invention; the said figures show the parts of the machine in different positions. I

1, 1 are mandrels, which are moved in an endless path in the direction indicated by the arrow and around which the sheets of tinfoil and the sheets of pasteboard, paper or the like are folded to form capsules etc. For making the inner capsule of tinfoil or the like the machine according to this invention is provided with an additional foldin device, which, in relation to the motion irection of the mandrels, is located before the ordinary device folding the sheets of paper round the mandrels. In the drawing the two folding devices, desi ated by A and B, are of the same constructlon. A strip of tinfoil 2 together with a strip of thin paper sustaining the tinfoil strip are pulled by two feed rollers 3 and 4 from a reel 5 and are placed in the front of a support 6 and two folders 8 and 9 located at the same flush with the said table, the said strips being then cut off by a knife 7 fixed to a swingable arm and actuated in any suitable manner. The sheets of tinfoil and papers thus cut from the strips are moved by one of the mandrels 1 into the 4 20 and 21 1921. Serial No. 483,084.

space between the two folders 8 and 9 and are forced against the sides of the mandrel, as shown in Fig. 2, during which operation two rollers 10 and 11, carried by swingable spring actuated arms 12 and 13 bear against the sides of the mandrel and force the sheets against the same. During the folding operation a third roller 15, carried by a swingable, spring actuated arm 14, forces the sheets against the front side of the mandrel. When the mandrel has arrived to the position shown in Fig. 2, it stops, whereupon the folder 9 forces the one edge part of the sheets respectively inwards to the mandrel 1. The other edge parts of the sheets are then forced inwards by the folder 8, so that the said edge arts are brought into the position shown at t e position at of the mandrel, Fig. 2. A presser 16 belonging to the mandrel and partaken in its motion, is then forced towards the mandrel and keeps the edge parts of the sheets in folded position. When the mandrel has arrived to the position a, which takes place, as the nextmandrel arrives to the position, in which the edge arts of the next sheets are folded by the 0 ders 8 and9 three of the bottom flaps of ca sule are folded by folders 17, 18 and 19. F0 ders 17 and 18 are carried by swingable arms,

which are provided with toothed segments meshing with each other, and are actuated by an arm 22, acted u on by a spring and cam disk, not shown. older 19 is carried by a swingable arm, which is actuated by an arm 23, acted u on by a s ring and cam disk, not shown. Folders 1 and 18 force inwards the narrow bottom flaps, whereupon the folder 19 forces inwards one of the broad bottom flaps. The second broad bottom flap is left in outstanding position, while the mandrel together with the capsule passes to the folding device B. On the folders of the said device B a sheet of paper 24, adapted to form the outer capsule, revious- 1 has been placed. The folding o the said sheet 24 around the mandrel carrying the capsule of tinfoil is effected in just the same manner as described above with reference to the sheet of tinfoil. While the paper sheet is folded round the mandrel the presser 16 is removed from the mandrel in order not to be in the way of the folders. When the mandrel leaves the folding device B, the paper sheet is folded round the mandrel, as shown in the position b of the mandrels, and the presser 16 keeps all the edge parts forced a ainst the mandrel. One of the edge parts 0 the paper sheet is provided with aste, so that.the capsule is closed permanent y. .The bottom flaps of the paper capsule are then folded. Preferably the folding device adapted therefore is so arranged, that it first folds the narrow paper flaps and then the unfolded tinfoil fla together with the adjacent paper flap, and finally the second paper flap, which, provided with paste, is fixed to the aper flap previously folded, one of the tinoilfiaps being thus simultaneously fixed so that it holds the tinfoil capsule in its position inside the paper capsule.

Owing to the fact that the folding oper ations are effected simultaneously at A and B and the folding of the bottom flaps of the tinfoil capsule takes lace, while the mandrels are at a standsti l at a and b, the additional folding device does not cause any delay in the o eration of the machine,-but the output of t e machine is the same as when sin 10 capsules are made.

e invention may, evidently, be modified in some respects without exceeding the limits of the same. The machine may be used' In a machine for making packets for containing cigarettes and the like, the combination of a plurality of mandrels movable in an endless path, and two sets of folders, one set of the folders being located behind the other set in the path of the mandrels, the mandrels successively passing through the said folders and the first set of folders serving to fold a sheet of tinfoil around each of the mandrels and the second set of folders serving to fold a sheet of paper around each mandrel carrying a folded sheet of tinfoil. In testimony whereof we have afiixed our signatures in presence of two witnesses.
