Abstract

Die Erfindung betrifft eine Einbaubohle für einen Straßenfertiger mit einer gegebenenfalls mit einem Vibrationsantrieb gekoppelten Bodenplatte (1), vor der in Einbaurichtung gesehen mindestens eine sich quer zur Einbaurichtung erstreckende, durch einen Antrieb (5) auf- und abbewegliche Stampferleiste (4) angeordnet ist, die elektrisch beheizbar ist. Hierbei ist mindestens eine benachbart zur Stampferleiste (4) angeordnete Spule (10) vorgesehen, die über eine Stromquelle (11) mit einem hochfrequenten Strom beaufschlagbar ist, der Wirbelströme in der Stampferleiste (4) induziert.

Figure 00000001
The invention relates to a screed for a road paver with a base plate (1), optionally coupled with a vibration drive, in front of which, when viewed in the installation direction, at least one tamper bar (4), which extends transversely to the installation direction and can be moved up and down by a drive (5), is arranged, which is electrically heated. At least one coil (10) is arranged adjacent to the tamper bar (4) and can be acted upon by a current source (11) with a high-frequency current that induces eddy currents in the tamper bar (4).
