A method for manufacturing a ring includes clamping a first region of a metal sheet against a mandrel, and, while the first region of the metal sheet is clamped against the mandrel, bending the metal sheet around the mandrel to join opposite end faces of the metal sheet and form the ring shaped to the mandrel. A system for manufacturing a ring from a metal sheet includes (a) a mandrel having a ring-shaped surface, (b) a clamp facing the ring-shaped surface and configured to clamp a first region of a metal sheet to the mandrel, and (c) a plurality of dies configured to bend the metal sheet around the mandrel, while the clamp clamps the first region to the mandrel, to join opposite end faces of the metal sheet and form a ring shaped to the ring-shaped surface.

A flanged ring connector (50) for connecting adjacent ends of HVAC ducting (52) includes an insertion flange portion to engage within the interior of the ducting. A mating flange portion (56) extends laterally or transversely to the insertion flange portion (54). A seat (58) is formed along the mating flange portion (56) to receive and retain a seal (60) and/or a reinforcing member or bead (90).

A die for attaching a washer to a grommet to create a grommet-washer assembly for use in a system for opening and closing window treatments is described. The die includes a top die and a bottom die. The grommet is placed onto a top surface of the bottom die, and the washer is placed on top of the grommet. When the press is actuated, the top and bottom dies press together to attach the washer to the grommet. A system and methods are also described that features the die and a press on which the top die and the bottom die are installed so that the combined grommet-washer assembly is creatable when the press is actuated to attach the washer to the grommet. The grommet-washer assembly does not rotate when used with a system for opening and closing window treatments.

An endless metal belt having an excellent abrasion resistance and a method for manufacturing such endless metal belts, capable of sufficiently reducing a tensile stress related to a metal ring in the innermost layer are provided. An endless metal belt includes a belt member formed by laminating a plurality of metal rings; and an element supported by the belt member, in which among the plurality of metal rings, a metal ring in an innermost layer is formed by a maraging steel plate, and another metal ring includes a nitride layer on its surface, and has a specific chemical composition; a tensile strength of the another metal ring is 1,700 MPa or higher; and a surface hardness of the nitride layer is HV800 to HV950.

For producing a welded ring, a band of a length corresponding to the circumference of the ring is bent into a ring and its two ends are welded together. The band ends to be welded together have an offset in the circumferential direction of the ring, the offset lying in the plane of the band. The welding is performed from both lateral edges of the ring, from the outside to the inside up to the offset. Welding having an overall improved welding quality and a higher tensile strength is thus obtained.
