The application of (for example, elongated strip-shaped) spots of adhesive paste to successive objects (such as paper or cardboard blanks which are to be converted into soft or hinged-lid packs for arrays of cigarettes) which are advanced stepwise below the nozzle or nozzles of one or more pasters at an adhesive-applying station is regulated by a control unit which receives signals denoting the speed of the conveyor for the objects and the position of the object at the adhesive-applying station. The control unit regulates the operation of the valve for each nozzle of the paster by taking into consideration the inertia of electrical and mechanical constituents of the paster. This ensures the application of spots having an optimum shape and an optimum position relative to the respective objects and containing predetermined quantities of adhesive. The control unit ascertains a compensation interval for the inertia which is added to or subtracted from a system-dependent correction interval which reflects the pattern of advancement of the objects.

Method for the application of adhesive spots to intermittently transported objects

The pot of a paster, such as a paster which can apply a flowable adhesive to a series of coherent blanks or to successive discrete blanks in a cigarette packing machine, receives a suitable adhesive from the discharge end of a suction nozzle. The latter has an intake end which can be introduced into supplies of adhesive in successive vessels of a series of two or more vessels. The suction nozzle carries a container which is at least partially filled with adhesive while the intake end of the nozzle draws adhesive from a vessel, and the thus at least partially filled container supplies adhesive to the intake end of the nozzle during transfer of the nozzle from an emptied vessel into a filled vessel. This ensures that the nozzle can supply adhesive to the paster while its intake end dips into the supply of adhesive in a vessel as well as while the intake end is being advanced from an emptied vessel into an at least partially filled vessel.
