1. A heating apparatus to heat a screed for a paving machine comprising:
- a screed plate having a substantially planar surface;
a second plate being spaced from the screed plate defining a space therebetween;
a heated gas inlet; and
a tunnel communicating the heated gas inlet to the space, at least some heated gas being directed from the tunnel substantially parallel to the surface.

Abstract
A heating device for heating a substantially planar screed plate for a paving machine comprising a plate being spaced from the screed plate, and a space being defined therebetween. A heated gas inlet feeds into a tunnel 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 with a orifice attached to the end of each tunnel orifice determining the direction where the heated gas will be directed.

10. A heating apparatus to heat a screed for a paving machine comprising:
-
a screed plate having a substantially planar surface; an inlet means for supplying heated gas; a second plate being spaced from the screed late defining a space therebetween; and a tunnel means for directing at least a portion of the heat gas substantially parallel to the surface within the space.

11. A heating apparatus for heating a screed for a paving machine comprising:
-
a screed plate having a substantially planar surface; a heated gas inlet; an insulator retainer, being spaced from the screed plate defining a space therebetween; a tunnel means for directing at least a portion of the heated gas substantially parallel to the surface within the space; and insulator means, being inserted on the side of the insulator retainer opposite the space, resisting heat transfer from the insulator retainer and the tunnel means.

12. A method of heating a screed for a paving machine comprising the steps of:
-
providing a screed plate having a substantially planar surface; spacing an insulating means a distance from the planar surface; creating a space between the insulating means and the planar surface; supplying a heated gas to a location distant from the space, in a non coplanar direction relative to the planar surface; and directing the heated gas from the heated gas supply to the space in a direction substantially parallel to the planar surface.
