ABSTRACT:
An apparatus for producing girders, as for example I girders, from lengths of wood forming the flanges and the web of the girder has a carriage running on rails through a first station in which lengths of wood are placed thereon for forming the girder, a pressing station in which the so put-together girder is first acted upon by an upright force normal to its web and parallel to its flanges, and then by a greater force acting horizontally on the girder so that the parts of the girder are kept lined up and in righted, straight condition, and through a HF station in which the girder is moved past HF electrodes for acting on the glue in the joins of the girder.
