  • the finishing machine 4 comprises a reaction element 50 operatively connected to machine 4 and to the smoothing device 20, so as to change the stand-by position of the smoothing device 20 relative to the machine.
  • the reaction element 50 comprises an anchoring bracket 54, integral with machine 4 and operatively connected to the connecting arms 42 by an adjustable bar 58, so as to change the orientation of the connecting arms 42 and thus the position of the smoothing device 20 relative to the surface to be covered 6 and to an abutment plane of the feeler pin 30 or reference plane 38.
  • the reaction element may comprise a screw and nut screw system or element or a cylinder and piston element.
  • Such systems may be manually, electrically, hydraulically or pneumatically actuated.
  • the support element 34 comprises a wheel 62 suitable for rolling on the reference plane 38 following a profile of the reference plane 38, parallel to the feeding direction X-X of the machine.
  • the support element 34 may comprise a sliding block suitable for abutting against the reference plane 38, following the profile of the reference plane 38.

  • the feeler means 30 are constrained to at least one of said panels 70, so as to change the cross position of the feeler means 30 adapting them to the cross dimension of the surface to be covered 6.
  • the distribution unit 12 comprises a pair of separators 78 arranged at an outlet portion 82 of the feeding means 16, so as to intercept the mix coming from the feeding means 16 and distribute it onto the surface to be covered 6.
  • separators 78 have smaller cross overall dimensions than the extension of the outlet portion 82 of the feeding means 16, said cross overall dimensions being measured perpendicularly relative to the feeding direction X-X of the finishing machine 4.
  • Separators 78 may be converging in a connecting zone 86 arranged in the proximity of the outlet portion 82 of the feeding means 16.
  • separators 78 may be both planar and curved so as to be convex on the side facing the outlet portion 82 of the feeding means 16.
  • separators 78 are arranged symmetrically relative to the outlet portion 82 of the feeding means 16.
  • the separators are turnably mounted relative to an actuating pin 90 arranged, for example, at the connecting zone 86 (figure 6) or at a crosspiece 94 arranged opposed to separators 78 relative to the feeding means 16 (figure 7).
  • the actuating pin 90 is arranged symmetrically relative to the outlet portion 82 of the feeding means 16, and the separators have the same dimensions so as to symmetrically divide the mix flow coming from the outlet section 82, into two side flows F (figure 7).
  • the actuating pin 90 may be arranged according to a direction substantially parallel to the surface to be covered 6, as well as to the feeding direction X-X, or the actuating pin 90 may be arranged according to a direction incident with the surface to be covered 6, for example on the smoothing device side; preferably, the actuating pin 90 is arranged on a plane parallel to the feeding direction X-X.
  • separators 78 are operatively connected to motor means suitable for operating the separators about said actuating pin 90.
  • the motor means may comprises a compound lever 98 provided with a screw and nut screw system.
  • the motor means may comprise an electrical or hydraulic motor.
  • machine 4 comprises first operating means 102, arranged on the side of smoothing device 20 and second operating means 106, arranged at the side opposite the first operating means 102.
  • the first operating means 102 comprise, for example, a pair of driving wheels, actuated by an electrical motor, a hydraulic motor, or by an internal combustion motor.
  • the second operating means 106 comprise a steering element arranged in a portion comprised between said first operating means 102 relative to the cross direction Y-Y perpendicular to the feeding direction X-X of the machine.
  • the second operating means 106 are comprised within the cross overall dimensions of the first operating means 102.
  • the second operating means 106 comprise a wheel 108 arranged at the same distance from said first operating means relative to a direction perpendicular to the feeding direction of the machine.
  • the finishing machine comprises a single front wheel 108 arranged symmetrically relative to the back wheels, within the cross overall dimensions of the same.
  • the second operating means 106 comprise a sliding block or a track.
  • the second operating means 106 are operatively connected to second adjustment means 110 suitable for adjusting the distance of the second operating means 106 from the surface to be covered 6.
  • the second adjustment means 110 may comprise a screw and nut screw system or a cylinder and piston system; said systems may be manually, electrically, pneumatically or hydraulically actuated.
  • the second operating means 106 are driving; for example, they may be actuated by a mechanical transmission system or by a hydraulic transmission system.
  • the machine proceeds according to a feeding direction so as to move the distribution unit 12 and the smoothing device 20 at the portion of surface to be covered 6.
  • the actuation of the feeding means 16 makes the mix fall by gravity, at the outlet section 82, directly onto the distribution unit 12.
  • Separators 78 of the distribution unit 12 intercept the mix flow symmetrically conveying it from opposite sides relative to the unit itself.
  • the mix layer laid and distributed by the distribution unit 12 is then intercepted by the smoothing device 20 which is operatively connected to feeler means 30. Thanks to its weight or to the action of a special additional thrust device, the smoothing device 20 shaves and levels the mix evenly spreading it along the front of the connecting edge 24 and compressing it, levelling it below it.
  • the support element 34 of the feeler means 30, during the machine feeding, rests on a reference plane 38, so as to ensure a predetermined minimum distance between the connecting edge 24 of the smoothing device 20 and the reference plane 38, and thus ensuring a fixed level of the layer of laid mix based on the minimum distance set through the feeler means 30, arranged in contact with the reference plane 38, from the latter.
  • the support element 34 adjusted in position with the feeler means 30 forms an abutment that prevents the smoothing device 20 from compressing the mix layer laid by the distribution unit 12 beyond a certain predetermined level.
  • the support element 34 creates a stop to the approach movement of the smoothing device 20 towards the surface to be covered 6.
  • the feeler means it is possible to use the plane defined by the blocks or kerbs of the kerbstone that delimit the kerbstone on at least one side of the same.
  • advancing the finishing machine on the kerbstone surface it is possible to make the support element slide on the road surface adjacent the kerbstone itself.
  • the finishing machine according to the invention allows overcoming the disadvantages of the prior art.
  • the finishing machine according to the present invention allows being actuated autonomously by a single worker and does not require any manual laying that would be unavoidably slow and inaccurate.
  • the finishing machine thanks to the use of a single front steering wheel allows being moved in small spaces having a limited steering radius.
  • the height adjustment of the front wheel ensures regular levelling of the machine relative to the surface to be asphalted even when the front wheel covers an uneven and rough portion as not yet covered by the mix layer. Thanks to the levelling between the front wheel and the back wheels, a better control of the smoothing device position is ensured.
  • the distributing separator exhibits small overall dimensions and requires reduced actuating power as compared to the screw systems typically used in the prior art.
  • the floating movement of the separator ensures an even distribution of the mix on the entire cross extension concerned by the passage of the smoothing device. Thanks to the floating movement of the separator it is possible to use mix distribution means of reduced dimensions. In fact, also separators of relatively reduced extension when rotated allow transversally distributing the mix even beyond the cross overall dimensions of the mix outlet. Thanks to the small separator, a lower actuating power is further required.
  • the levelling device ensures a minimum and constant height between the working edge or wall of the smoothing device and a reference plane. In this way, the planarity of the asphalted surface as well as the levelling of the same relative to the reference plane are ensured.
  • the smoothing device is not subject just to the driving force of the machine and to the forces transmitted by the laid mix layer, but it is also forced to move towards the laid layer relative to a predetermined minimum distance relative to the reference plane.
  • the feeler means follow the profile of the reference surface during the laying operation, while the support element prevents the smoothing device from excessively compressing the layer of laid mix; in other words, a minimum distance is ensured between the smoothing device edge and the reference plane, and thus between the smoothing device edge and the surface to be asphalted, beyond which the smoothing device cannot sink.
  • the reference plane is given in case of kerbstones by stone blocks that laterally delimit the kerbstone itself.
