Abstract
The device presents a number of supports associated with a number of machining heads and located at the front of the machine. For each machining head, the supports are located on two superimposed surfaces for respectively supporting a pack of boards for loading and a pack of boards unloaded off the work table. The supports are fitted to a frame which is moved vertically to position the two surfaces at the table, and which is also movable laterally for enabling access to the machine. The device also presents a cross member movable along the Y axis; and a number of arms for alternately engaging two opposite edges of the packs and transferring them between the table and the supports. The arms are connected to a common connecting rod which is moved to rotate and withdraw them clear of the packs during the idle movement of the cross member.
