发明名称 Double plane bend former
摘要 A bending apparatus (10) for use in bending moldings (300 and 301) having a decorative outer surface (308) is described. The bending apparatus includes an upper bending member (12) and a lower bending member (52) which are moved together to form intricate compound bends in the molding. The bending surface (14) of the upper bending member has a variable curvature which is controlled by adjustment units (38). The lower bending member includes first and second outer tool members (54 and 56) and a middle tool member (120). The moldings are mounted onto the holders (102) of the tool members during bending. The outer tool members pivot along two axis in response to the pressure of the upper bending member during bending. The middle tool member pivots along one axis and is compressed downward during bending. The bending apparatus allows double plane bends to be formed in the molding without damaging the decorative outer surface of the molding.
