A paving machine (20) employs an electrically heated screed assembly (30) to uniformly heat a screed plate (46) of the machine. Uniform heating is achieved by inserting a thermally conductive plate (62) between electrical heating elements (60) and the screed plate (46). An insulation layer (68) may be provided above the heating elements (60) to direct the heat downward into the thermally conductive plate (62). The heat spreads relatively uniformly throughout the termally conductive plate (62), thereby uniformly heating the screed plate (46). A clamping mechanism (74) is also provided that, when tightened, provides a compressive force, thereby holding the assembly in place. When released, the pressure is alleviated, thus permitting a heating element to be removed for repair or replacement without the need to remove the screed plate.
L'invention concerne une finisseuse (20) utilisant un ensemble lissoir (30) à chauffage électrique afin de chauffer uniformément une plaque de lissage (46) de la machine. On obtient un chauffage uniforme en insérant une plaque thermoconductrice (62) entre des éléments (60) de chauffage électrique et la plaque de lissage (46). Une couche isolante (68) peut être placée au-dessus des éléments chauffants (60) afin de diriger la chaleur vers le bas dans la plaque thermoconductrice (62). La chaleur se répand de manière relativement uniforme à travers toute la plaque (62), chauffant ainsi uniformément la plaque de lissage (46). Un mécanisme de préhension (74) fournit, une fois serré, une force de compression qui maintient l'ensemble en place. Lorsqu'il est desserré, la pression est allégée, ce qui permet de déposer un élément chauffant en vue de sa réparation ou de son remplacement sans démonter la plaque de lissage.
