Abstract
One side of a running web of wrapping material of the tobacco processing industry is provided with adhesive by a nozzle which discharges a stream of minute droplets of liquid adhesive. The droplets are charged by a first electrode immediately after they issue from the orifice of the nozzle and the droplets of the stream are thereupon deflected relative to the running web by a pair of deflecting electrodes whose operation is controlled by an adjustable circuit so as to ensure that the application of adhesive can take place in accordance with variations of one or more parameters including the speed of the running web and/or the permeability of wrappers which are obtained from the adhesive-coated web.
