A heat transfer system in which a continuous web of material (13, 14) is carried past a hot plate surface (12) with one face of the web in contact therewith, and a series of fluid-filled vessels (15) above the web to apply a load on the upper surface thereof to maintain uniform contact between the web and the hot plate surface irrespective of any undulation thereof. A transport section to convey the web past the hot plate surface comprises upper and lower traction belts (16, 17) disposed entirely beyond the end of the hot plate surface (12) with a fixed plate (18) beneath the lower belt (17) and a series of fluid-filled vessels (19) above the upper belt (16) which serve to maintain adequate drive contact between the belts (16, 17) and the web (13, 14). By positioning the traction belts beyond the heating section of the system belt, wear is minimised when compared with known systems where an upper traction belt passes also through the heating section, and still further the length of the upper belt is reduced thus minimising manufacturing costs. |
