Abstract
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 so as to heat up a heating surface facing a road subsurface, and wherein the heating element comprises a heating layer at least partially 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. Further, a tamper bar for a road finisher and a method of manufacturing a tamper bar are provided.

2. A method of manufacturing a tamper bar, comprising the following steps:
-
forming an upper tamper bar member; forming a lower tamper bar member; forming a groove in either one of an upper surface of the lower tamper bar member or a lower surface of the upper tamper bar member; applying a heating layer of a heating element to a surface of the groove via thermal spraying; and assembling the lower tamper bar member and the upper tamper bar member so as to form the tamper bar. - View Dependent Claims (3, 4)
