818,684. Delivering cigarettes in orderly arrangement. KÍRBER, K. Oct. 4, 1956, No. 30261/56. Class 130. [Also in Group XXX] So that all the cigarettes 1, 25, Fig. 13, on two parallel machine take-off belts may have tips or mouthpieces similarly directed, the cigarettes 1 are turned end-for-end by means 23 disposed to a helical path in the feed direction and which may deposit them on or between the cigarettes 25. The means 23 may be parallel to the belts so that the cigarettes 1 are gripped at their ends only, but as shown, they coact fully with an inclined means 23 after deflection by a sponge roller 24. The means 23 may be a single belt 2, Fig. 3, having an inherent twist of 720 degrees and looped into a figure-of-eight round four rollers (not shown); two belts 8, 9, Fig. 6, in mutually crossing relation, each of which may be a crossed belt, as shown, or an open belt having an inherent 180 degree twist; or a belt 8, Fig. 7, rolling cigarettes along a helical channel 12, or carrying them therealong by virtue of suction orifices or upstanding fins of the belt. The helical channel 12 may be used without a belt if the cigarettes are positively fed thereinto or if the channel is vertical or inclined so that the cigarettes feed through by gravity. The belts of Figs. 3 and 6 may be backed by twisted guides at their crossing portions, and rollers may be provided to adjust the spacing between the belt runs or to tension the belts, and rollers or rails to guide the cigarettes laterally near their ends. Rubber belts with a foamed rubber surface may be used. To ensure a symmetrical action the rollers at the outlet end in Figs. 3, 6 and 7 may be coned and turned slightly to one side in the conveyance plane. Reference is made to the use of a series of rollers as the cigarette-turning means.
