Abstract (en)
[origin: WO2009095146A1] The invention relates to a device for compacting road paving materials, comprising a screed board which is fastened on a road finisher and extends at a right angle to the direction of travel of the road finisher and a tamper that is mounted in front and/or behind the screed board. Said tamper has a tamper strip (9) that can be driven to perform a striking upward and downward movement and the interior of which is equipped with an electrical heating unit in the form of a rod-shaped heating element (12) that can be clamped into a recess of the tamper strip. The device according to the invention is characterized in that the heating element is a tubular heating unit the coil (20) of which is folded at least once on a free end of the tubular heating unit, thereby forming two adjacent rods (33, 34) that are connected to a power supply unit in a common terminal block (14).
