The invention concerns an automated device for maintaining wooden elements on a pressing table for assembling them. It is made up of a pressing table (1) with a wooden plate (3) and a mobile gantry (2) comprising a magazine for storing saw logs (4) consisting of vertical spindles mounted on a rail (9) laterally fixed on the gantry and on which can be strung the saw logs which comprise a vertical bore with spring balls maintaining them by means of grooves provided on the spindles, a motoring unit sliding along the rail for placing, removing and storing the saw logs, being equipped with a vertically mobile gripper comprising a lateral U-shaped opening for being inserted in ring-shaped grooves provided at the periphery of the saw logs. The invention is designed for making various types of assemblies such as frame elements, and particularly prefab main trusses of restricted dimensions known as "false gable trusses", and widely used in traditional construction for supporting sloping roofs. |
