Filed: 1928-10-26
Abstract: 322,853. Marks, Sir G. C., (International Cigar Machinery Co.). Oct. 26, 1928. Packeting by wrapping-up.-A device for folding the overhanging end of a wrapper on a cigar, stick of candy, or similarly shaped article, comprises a number of fingers arranged about and reciprocated along the common axis, the fingers acting successively to fold the wrapper end during the withdrawal. Fingers 26 - - 29 are pivoted on the sides of a block 31 which is reciprocated by a shaft 33 and cam 41. The fingers are pressed towards the axis by springs 32 but are normally held in the inoperative position by a cam 42, sleeve 34, head 50, and projection 51 acting on the tails 55 of the fingers. The cigar C with its foil wrapper F is supported by jaws 25 on a turret, not shown, the block 31 &c. is advanced by the cams to the position shown, the head 50 is then withdrawn to release the fingers, and the block and head are withdrawn together to allow the fingers to operate. The block and head are then allowed, by the cams, to advance under the action of a spring 63 and cause the flat face of the finger 29 to press the folded flaps against the end of the cigar, the angle of said face being varied by adjusting the relative positions of the shaft 33 and sleeve 34 by means of a stop 66. One or more of the fingers may be held in inoperative position, after the withdrawal of the head and until said finger, say 29, is in position to fold, by a spring trigger 69, Fig. 6, which engages a pin 74 on the tail 55 until tripped by a fixed bar 75. The acting ends of all the fingers except the last, are narrower than the article. In a modification six fingers are employed and in another only two, in this case both the fingers operate on the wrapper two or more times, the block 31 being rotated about the axis after each operation through an angle of 90‹ for a square package P, Fig. 19, 60‹ for hexagonal, &c.
