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.

A heat exchange assembly comprises a solar heat collector panel adapted to be mounted on a portable support. The panel includes a rigid frame portion, an upper planar surface portion, a bottom planar surface portion and a planar, continuous tubular coil formed by a single, continuous tubular coil formed by a single, continuous tube member disposed between the upper and bottom surface portions. The upper planar surface portion includes a sheet of solar ray penetrating material and the bottom surface portion includes a sheet of rigid backing material. The rigid frame portion extends around the entire periphery of the panel to define the outer profile thereof. The rigid frame portion includes a channel which receives the outer edges of the upper sheet of solar ray penetrating material and the bottom, rigid backing sheet with the tubular coil disposed therebetween to fix the sheet of solar ray penetrating material, the tubular coil and the bottom surface portion into a unitary structural configuration. Specific features of the invention are directed to the particular structure of the channel member, the specific structure of the portable support and the particular interrelationship between the various elements of the overall assembly.
