Patent number: 8763437Abstract: An apparatus includes a roll former with rolls configured to form a structural beam from sheet material, and a sweep unit for longitudinally sweeping a beam in any of vertical, horizontal, or combination directions. The sweep unit has a first pair of forming rolls positioned to engage first opposing sides of the structural beam and has a second pair of forming rolls positioned to engage second opposing sides of the structural beam. The sweep unit movably supports the first and second pairs of forming rolls so that any selected one of the forming rolls continuously engages an associated side of the structural beam while an associated one of the forming rolls opposing the selected one forming roll moves downstream and around the selected one forming roll. This provides a very stable beam-bending condition promoting dimensional stability during the sweeping process, and hence dimensional accuracy and repeatability.Type: GrantFiled: October 31, 2012Date of Patent: July 1, 2014Assignee: Shape Corp.Inventors: Richard D. Heinz, Bryan E. Gould

Patent number: 8151614Abstract: A cutoff unit for cutting a variably swept continuous beam extending from a roll forming mill includes a pickup subassembly for tracking a shape of the continuous beam, and a cutoff subassembly that engages and supports sides of the continuous beam while a blade slices transversely through the continuous beam. A controller connected to the roll forming mill and to the cutoff unit controls the cutoff unit to allow pass through of the continuous beam, and is configured to actuate the pickup and then actuate the blade to cut the continuous beam into longitudinally symmetrical beam segments, each having a center section (swept or not) and with mirror-image equally-swept end sections.Type: GrantFiled: May 29, 2008Date of Patent: April 10, 2012Assignee: Shape Corp.Inventors: Richard D.

Patent number: 7882718Abstract: A computer controlled roll-forming apparatus is adapted to provide a repeating pattern of different longitudinal shapes to a continuous beam “on the fly” during the roll-forming process. A sweep station of the apparatus includes a primary bending roller tangentially engaging the continuous beam along the line level and an armature for biasing the continuous beam against the primary bending roller for a distance partially around a downstream side of the primary bending roller to form a sweep. Actuators adjustably move the armature partially around the downstream side of the primary bending roller between multiple positions for imparting a series of different longitudinal shapes. Internal and external mandrels control wall stability to allow even sharper sweeps. In one form, the apparatus also includes a coordinated cut-off, so that when separated into bumper beam segments, the ends of the individual beam segments have a greater sweep than their center sections.Type: GrantFiled: March 21, 2007Date of Patent: February 8, 2011Assignee: Shape Corp.Inventors: Bruce W.

Publication number: 20100147728Abstract: An energy-absorbing bulkhead apparatus includes high-strength roll formed tubular bars, and a bar-supporting sheet to distribute stress from product shifting in large shipping containers during transport. Parts are re-useable and can be quickly installed into the shipping container at selected locations such as near the container's doors. The bars can be swept and/or have deformed/configured ends shaped to engage channel features in side walls of the large shipping container. The bars may define spaced tubes and a tie rod for added strength. For example, the bars can be steel having 120 KSI to 220 KSI tensile strength, and have a cross-section 2-3 inches in depth and 4-6 inches in height, a length of 94 long, and a longitudinal sweep of 6 inches curvature. A flexitank can be positioned in the shipping container and supported by a combination of the bulkhead.Type: ApplicationFiled: December 15, 2009Publication date: June 17, 2010Inventors: Melvin Guiles, Todd Armstrong, Richard D.

Publication number: 20080098601Abstract: A method includes steps of providing round tubing, providing a compression box and wedging dies, and reshaping the round tubing into a single or double-tapered rectangular tube including using the compression box to control an outside shape, while using the wedging dies to force material of the tubing outwardly toward the compression box. This arrangement minimizes material thinning. A tubular crushable structure is produced that is designed for longitudinal impact-energy-absorbing capability. The crushable structure includes a single or double-tapered rectangular tube made of material having a tensile strength of at least 40 KSI. In a narrower form the tensile strength is at least 80 KSI, though it can be 100 KSI or higher.Type: ApplicationFiled: June 21, 2007Publication date: May 1, 2008Inventors: Richard D. Heinz, Bruce W.
