ABSTRACT:
Apparatus for spreading a fluid or like substance, for example, an emulsion for bonding bituminous coated material on the surface of a road including a mobile machine, at least one spreading bar along which the spreading is at least partially effected, and at least one ejection nozzle associated with the at least one spreading bar. A supply circuit supplying emulsion to the nozzle. The at least one nozzle is associated with a mechanism for controlling delivery of the emulsion and a mechanism for controlling positioning of the nozzle relative to the machine. Both of the mechanisms are operated simultaneously, in dependence on the movement of the mobile machine, in such a manner that the nozzle effects spraying by sequenced jets of the substance to continuously cover the surface which is to be spread. The machine provided with this apparatus is of the finisher type.
