Abstract
A device for applying adhesive to the wrapper in a cigarette making machine (particularly upstream of the garniture) includes a conveyor for conveying the wrapper web (18) along a path between two guides (24, 26), a pair of nozzles (28, 30) each of which is movable into and away from contact with the wrapper web, and a device (36) for controlling the positions of the nozzles so that one nozzle at a time is brought into contact with the wrapper web and that the inoperative nozzle lies in a retracted position at which a brush (32) is provided for automatically removing the adhesive string from it, the arrangement being such that movement of the thus-cleaned nozzle towards the wrapper web is continued so as to displace the wrapper web from the previously active nozzle, which is then retracted for cleaning, whereupon the newly active nozzle is slightly retracted to assume its normal operating position adjacent to the wrapper web at which it will apply adhesive until the other nozzle, in a similar manner, displaces the web from it to allow a similar cleaning operation.
