jection 17 moved out of the path of the rod 18, see Figs. 3 and 5. The plunger 22 then moves five boxes from the channel 4 into the channel 7 and, it may be, also forwards in the channel 7 boxes previously pushed into the same. lPlunger 22 moves the boxes for a distance somewhat greater than the length of the boxes.

All vchannels 7, 8 and 9 are constructed in the same manner. The rst part of each channel is trunk shaped and helicoidal an angle of 90 so that the bottom and the top walls of the channel will constitute the side walls of the Jsame and one of the side walls will form the bottom wall, as shown in Fig. 6. Owing to this arrangement, the boxes a of each set instead of being located side by side in a horizontal row as shown in the part of the Fig. 6, will be located one upon the other in a vertical stack, as shown at the The sets of boxes located in the manner last mentioned are transmitted from the channels 7, 8 and 9 into the channels 10, 11 and 12 respectively by plungers 27, 28 and 29 respectively substantiallyof the same construction as the plungers 23 and actuated in substantially the same manner as the same. 31 and 32 co-operate with the plungers 27,

28. and 29 and prevent the same from operating until a'grop `of livesets of superposed boxes has been placed in front of the plungers respectively.

s seen from above, the boxes are placed on the table 13 in three rows, delivered by the channels 10, 11 and 12 respectively. Each row comprises live sub-rows located laterally of each other and each composed of sets of five superposed boxes. The channels 10, 11 and 12 terminate at different points b, c and d respectively. At each delivery point a pile f of paper sheets is located on the table and owing to the manner in which the boxes are delivered, a single operator will be able to wrap up all the boxes into packets each comprising, for instance, fifty boxes. The boxes delivered by the machine 1 for instance must not necessarily be of the same size as those delivered by the machine 2 or 3 and the cigarettes may differ in quality. A Owing to the fact that the channel 7 has a considerable length, the bottom of the last part of the said channel consists ofan endless belt 33, passing round rolls 34Vand 35. Roll 34 vis rotated by means 0f a ratchet wheel 36, connected with the said roll, and a pawl 37, provided on a swingable arm 38 and by means of a link 39 actuated by the lever arm 20 every time the plunger 22 transmits a set of boxes from the channel 4 into the channel 7 and forwards the set of boxes located in the firstpart of the channel, so

that the belt 33 forwards the sets of boxes Alocated in the last part of the channel simul- Feelers 30,

of the boxes would stick to one of the side walls of the channels and be spread on the same during the movement of the boxes, so that finally boxes can not pass through the channels. In order to remove the said disadvantage one 40 of the side walls of the channels 4, 5 and 6 is movable toward and from the opposite side wall 41 and preferably carried by two or more swingable arms 42. The side wall 40 is oscillated by any suitablemotion transmitting device actuated by the driving shaft of the machine. The said wall 40 is moved from the wall 41 each time the row of boxes contained in the channels 4, 5 and 6 respectively is fed forward in the channel, thus releasing the boxes. After the Vfeeding operation the wall 40 is again forced against the boxes.

In this manner the end flaps of the boxes are repeatedly forced against one another, their sticking together being thereby ensured. Besides a suiiciently great play is provided for the boxes during each feeding operation, which results in substantially no paste being spread on the side of the channel.

The transporting device may evidently be modified in some respect without exceeding the limits of the invention.
