Road finisher with heated tamper bar
First Claim
1. A road finisher, comprising:
- a screed plate extending at right angles to the working direction of the road finisher; and
a tamper bar disposed rearwardly and/or forwardly of the screed plate in the working direction, wherein at least one electrically operated heating element is present, which is configured to heat up a heating surface facing a road subsurface, and wherein the heating element comprises a heating layer at least partially comprising a thermal spray coating obtained through thermal spraying onto a substrate surface, wherein the tamper bar is made from two parts with an upper tamper bar member and a lower tamper bar member assembled together;
wherein the upper tamper bar member has a lower surface which, in the assembled state, contacts an upper surface of the lower tamper bar member, wherein a groove is provided in the lower surface of the upper tamper bar member; and
