Process and machine for manufacturing shaped profiles in curved plywood for covering columns and the like

摘要

A process and a machine for manufacturing shaped profiles in curved plywood are described .A set of flat wooden sheets (1) with interposed adhesive (2) is submitted at temperature and pressure by means of a shaped press (3) at high temperature which determines the mutual adhesion of the sheets and their bending up to the desired shape. Said pressure is obtained by means of inflating an inflatable flexible sack (5) which substains said flat sheets (1) beneath said press (3). <IMAGE>
