<p>The truss members and connector plates are assembled on a conveyor surface (19), which transports the truss members to a first pressing station (20 and 22) where the connector plates are partially embedded into the truss members and then to a second pressing station (24) where the connector plates are substantially completely embedded into the truss. The pressing rollers (20, 22 and 24) have substantially the same diameter and are sufficiently large to prevent the connector plates from rocking back and forth during the initial stages of the pressing operation.</p> |
