Method for constructing panels for roller shutter boxes, a plant for implementing the method, and a panel obtained by the method

摘要

A method for constructing roll shutter box panels, comprising the following steps: forming a metal strip to obtain a continuous shaped strip (6). injecting a polyurethane foam into the shaped strip (8), applying a deformable film (12) onto said foam, deforming said foam in accordance with a defined contour (14), polymerizing the foam until it hardens (20), and cutting the shaped strip to obtain a panel of desired dimensions (22).
