Open the CIPO recordAbstract From the Canadian patent
In a double-band or similar press the pressure on the mat (10) that is being fed in is increased so rapidly as soon as this mat comes into contact with the heat-transfer surfaces (1 2) that, the outer areas of the mat (10) hardens under the great pressure whereas the heat has still not penetrated into the interior of the mat (10). This results in an enhancement of the surface quality of the panel (P). As an example to this end, a roller, gap (17) can be provided before the feed gap (13). (Figure 1)
