Abstract

In the production of extruded plastics armoured board, stabilization of the board is effected by successively cooling and reheating the hot strip of armoured board issuing from the extruder die. The cooling is effected in a heat-exchanging thicknesser with the flow of cooling fluid passing counter to the direction of feed of the strip and branching laterally from central longitudinal ducting to outer longitudinal ducting so that the cooling is more intense along the centre of the strip than at the side margins of the strip. The cooled strip is then subjected to ambient air after which it passes into a heater where infrared lamps heat the strip more intensively at the side margins thereof than at the central longitudinal zone thereof.
