Abstract
A device for simultaneously spreading cut fibers and binders on a roadway width, includes, in the longitudinal direction, a first binder spreading set, a second cut fiber spreading set and a third binder spreading set, the second set including cutting tools, which are driven by a torque transmission member. The device is modular, the modules being transversally arranged side by side and each allowing to spread on a longitudinal lane of the roadway binders and cut fibers. Each module has a first nozzle, a tool for pulling and cutting continuous fibers and throwing cut fibers to the roadway, a second nozzle, the nozzles being connected to a common binder dispensing member. Each tool is removably mounted in its module between a working position where it is in the module and driven by the driving shaft and a releasing position where it is available to an operator and at rest.
