Abstract
A cigarette making machine has a suction tape 10 for carrying the cigarette filler stream 18 onto a wrapper web 22, the tape being supported by a single cable 32 which extends above the edge portions of the operative lower run of the tape and crosses over (at 34 in FIG. 2) beneath the non-operative upper run of the tape. The cable is tensioned sufficiently to provide an adequate frictional drive from one of the pulleys (12) around which the tape and cable pass. The tape needs only slight tension, being driven partly by frictional contact with the cable.
Claims7
A cigarette making machine including an air-pervious tape which is arranged to carry a cigarette filler stream, with the aid of suction, towards a rod-forming device in which the filler stream is enclosed in a continuous wrapper web to form a continuous cigarette rod, the edges of the operative run of the tape being supported by an endless moving cable arranged to form two parallel lower runs which lie above and extend along edge portions of the operative lower run of the tape in contact therewith, and upper runs which cross over beneath the non-operative upper run of the tape.
A cigarette making machine including an air-pervious tape which is arranged to carry a cigarette filler stream, with the aid of suction, towards a rod-forming device in which the filler stream is enclosed in a continuous wrapper web to form a continuous cigarette rod, the edges of the operative run of the tape being supported by one or more cables including first tensioning means whereby sufficient tension is created in the cable or cables to produce a frictional device from one of the pulleys around which the tape passes, and second tensioning means whereby the tape is tensioned.
