Abstract: 366,662. Packeting cigarettes; making boxes. UNIVERSELLE CIGARETTENMASCHINEN-FABRIK J. C. MœLLER & CO., 48, Zwickauerstrasse, Dresden, Germany. Dec. 18, 1930, No. 38204. Convention date, Nov. 8. [Classes 18 and 94 (i).] In a machine for packeting cigarettes &c. in drawer and shell boxes, the drawer blank, adapted to carry the cigarettes, is superposed on the partly folded shell blank and is then charged with cigarettes, after which the folding of the drawer blank is completed, and the shell is folded around the drawer. The shell blanks 62 are fed from a magazine 61, Fig. 1, over a recess in a rotating turret 63, into which they are thrust by a plunger 64. The turret rotates and a folder 74 turns down the upstanding part so that the blank now has the form shown in Fig. 3. A blank 76 to form the drawer is taken from a magazine 75 and is thrust into the recess and upon the partially folded shell blank as shown in Fig. 4. The flap 76a is turned down and a charge of cigarettes 87 inserted at the next position. At the next station a card 95 is superposed on the charge and the assembly is now as shown in Fig. 6. During the succeeding movement, the flaps 76a, 76b are turned upwards and downwards respectively, and a ram 103 forces the packet on to a belt 71. A finger 104 turns down the upstanding portion of the flap 76a and folding members 105, 106 complete the application of the shell to the drawer. Before the folder 106 has acted, a wheel 107, Figs. 1 and 11, applies adhesive to the last flap 62b, and a thin flat rib 108 is disposed at the side of the packet so as to take the pressure caused by the action of the folder 106. The rib is withdrawn by the movement of the packet. The Specification as open to inspection under Sect. 91 (3) (a) describes also a machine in which the shell is formed separately and the charged and folded drawer is inserted therein. In this modification, the shell is formed from a blank 1, Fig. 1 (Cancelled), which is brought above a channel 2 and pressed thereinto by a block 3. The folded blank is fed by projections 12 on a chain 9 so as to embrace a core 16, a fixed curved folding member 17 turning the portion 1a of the blank into a horizontal position. A wheel 18 applies gum to the edge, which is then turned down to complete the shell. The blanks 25, to form the drawers, are fed beneath a block 28, which forces them into a recess 26 in a rotating wheel 27. The wheel then rotates in an anticlockwise direction, folders 38 turning the part 25a vertically downwards, At the next position of rest, a batch 41 of cigarettes is thrust into the blank, the assembly being as shown in Fig. 6 (Cancelled). At position 45, a sheet 46 from a magazine 47 is placed on the cigarettes, and during the next quarter revolution folders 48, 49 turn the ends 25a, 25b up and down respectively into the plane of the top of the packet. The completed shell is at position 24 and is held there by a plate 55 while a plunger 53 thrusts the drawer and contents into it through a mouthpiece 54. A plunger 60 thrusts the completed packets out of the machine, and the plate 55 rises to allow another shell to occupy position 24. This subjectmatter does not appear in the Specification as accepted.
