Abstract
A press for making a continuous sheet from composite material has upper and lower press belts having respective lower and upper reaches that vertically spacedly confront one another across a press gap having an upstream inlet end and a downstream outlet end, and that have transversely spaced outer edges extending in the direction. The belts are advanced direction and thereby draw a mat of the composite material in the inlet end, compress it into the sheet, and expelling the sheet from the downstream end. Two transversely spaced elastic seal strips extend in the direction in the gap and are each engaged between a respective one of the outer edges of the upper belt and the respective outer edge of the lower belt. Each belt has at each of the edges a surface in engagement with the respective edge strip and having an average peak-to-valley height of less than 1 μm.
