ABSTRACT:
A process for combining layers of aramid waterleaves into a multi-ply structure wherein the layers are brought together in closely spaced relationship while being forwarded under low tension through a heating zone, the layers are heated, the layers are separated by mechanical means and purged by a stream of dry air to expel moisture-laden air from between the layers in a transverse direction while preventing moisture-laden air from moving along with the layers in the downstream direction, the layers are brought together, further heated and compacted under heat and pressure.
