<p>A heating device for heating a substantially planar screed plate (24) for a paving machine comprising a plate (48) being spaced from the screed plate, a space (50) being defined therebetween. A heated gas inlet (28) feeds into a tunnel (36) connecting to the space. At least some of the heated gas is directed from the tunnel substantially parallel to the screed plate. The tunnel is formed from a plurality of tunnel branches (36, 40) with an orifice (46, 44) attached to the end of each tunnel orifice determining the direction where the heated gas will be directed. <IMAGE></p> |
