(54)	Process and machine for manufacturing shaped profiles in curved plywood

(57) A process and a machine for manufacturing shaped profiles in curved plywood are described. A plurality of several flat wooden sheets (1) with interposed adhesive (2) is subjected to temperature and pressure by means of a shaped press (3) at high temperature, which makes the sheets themselves adhere with each other and bend up to a desired shape. Said pressure is obtained by inflating flexible pipes (9,10) placed parallel to each other along the longitudinal extension of the flat sheets (1).
