Patent number: 11596995Abstract: A die assembly having a bending die and a clamp die. The bending die comprises one or more movable plates and a wedge plate. The bending die includes a channel formed in one or more of the plates configured to receive a pipe or other workpiece to be formed. The movable plates are movable between a first position wherein each plate is spaced from the adjacent plate a predetermined distance and a second position wherein each plate is compressed so there is less distance between the plates. Movement of the wedge plate from the retracted position to the engaged position causes the movable plates to move from the first position to the second position. Compression of the movable plates correspondingly reduces the width of the channel to help grasp any workpiece inserted therein.Type: GrantFiled: June 21, 2021Date of Patent: March 7, 2023Assignee: Morton Industries LLCInventors: Russ Argadine, Justin Barnewolt, Gary Schmitt, Curt Humes

Patent number: 11577292Abstract: Devices, systems, and methods are directed to formation of tubular structures, such as spirally formed structures, having spirally extending reinforcing material. In particular, tubular structures can be formed in a continuous process in which a first material is spiral formed along a first spiral and a second material is joined to the first material along a second spiral to reinforce the spirally formed first material. As compared to manual application of reinforcing material, such a continuous process can facilitate producing tubular structures at rates suitable for high-volume, commercial fabrication. Further, or instead, as compared to the use of circumferentially extending reinforcing material to support a spiral formed tube, reinforcing the spirally formed first material with a spiral of the second material may offer certain structural advantages, such as improved resistance to buckling.Type: GrantFiled: January 5, 2018Date of Patent: February 14, 2023Assignee: KEYSTONE TOWER SYSTEMS, INC.Inventor: Eric D.
