Door leaf and production method

摘要

The door leaf (10) is formed from two metal sheets (200,202) forming a cavity (204) between the metal sheets and a door panel (206) in the cavity. The door panel is bonded with the metal sheets. The former metal sheet is bonded with the door panel in certain areas with a bonding pattern (208) formed from bonded- and unbonded areas. The latter metal sheet is bonded with the door panel in certain areas with another bonding pattern (212) formed from bonded- and unbonded areas. The two bonding patterns are formed in a different manner. Independent claims are included for the following: (1) a door with a frame; and (2) a method for manufacturing a door leaf.
