<p>A process for forming a belt for a press, such as a shoe press belt, include s the steps of: providing an elongate cylindrical core (20) having a longitudinal axis (A1); rotating the core (20) about the longitudinal axis (A1); providing a nozzle (22) movable along a nozzle path that is substantially parallel to and above the core longitudinal axis, the nozzle (22) having at least an upstream outlet (24) and a downstream outlet (26), t he nozzle outlets being longitudinally offset a distance from each other; and applying multiple strips of polymeric material to the core (20) through the nozzle outlets (24, 26) as the nozzle (22) moves along the nozzle path such that the downstream strip forms an overlapping spiral inner layer and the upstream strip forms an overlapping spiral outer layer that overlies the inn er layer.</p> |
