<p>The aim of the invention is to be able to quickly and inexpensively switch a finisher between a structure required for a single-layer application and a structure required for a two-layer application. Said aim is achieved by designing and further developing a finisher, in particular a concrete paver or slip-form paver, comprising a main frame (1), a front traveling gear (3) arranged at a front end (2) of the main frame (1), a rear traveling gear (5) arranged at a rear end (4) of the main frame, "front" and "rear" being in relation to the direction of operation of the finisher, and an additional device (6) for applying two layers of given substances, in such a way that the additional device (6) is arranged essentially in front of the front traveling gear (3) or essentially behind the rear traveling gear (5) in the direction of operation of the finisher.</p> |
