Abstract: An improved hemming die fixture, used in conjunction with a sheet metal press, is disclosed. The fixture is attachable to the ram, or ram assembly, of a metal press and carries with it a hemming die. The fixture is automatically displacable between working and standby positions. When not in use, the hemming die fixture is placed in a standby position wherein it is placed parallel to the ram of the press, and away from a primary die on the bottom of the ram. When required, the fixture may be actuated to place a hemming die parallel to, and below, the primary die located along the bottom of the ram. The hemming die then coacts with the work table, or second flat hemming die, of the press to form a hem along a longitudinal edge of a piece of sheet metal in a plane other than the plane in which a full bend is first formed along the edge of the sheet metal.

Abstract: An improved clip for supporting standing seam roofing panels on purlins or joists is disclosed. When used, this unique clip will not only support a standing seam, formed by two adjacent, connecting roofing panels, on a purlin, but will also accommodate both rotational and translational movement of the panels relative to the purlin. The disclosed clip is formed with several basic components: a base which is attachable to a purlin or joist; a middle piece which is capable of rotational displacement relative to the base; and a moveable top piece which is capable of translational, sliding movement relative to the middle piece. When in use, the top piece of the clip will coact with the interior of the standing seam to form a substantially tight, non-moving union with the seam. The base of the clip will be attached to the joist or purlin to support the roofing panels.
