T&H Lemont Inc. recently designed, built, and shipped a roll forming machine for a customer that specializes in retail displays. Because the customer focuses on the retail environment, the company is familiar with the daily use and occasional abuse that its products endure. Its reputation rests on designing and delivering products that are built to last, and it chose a T&H Lemont machine to fortify this reputation. The customer’s interest in investing in this machine involved producing a kick plate, a width of contoured steel that protects the base of most display racks and cabinets.
The unit, an RA11-18, is based on T&H Lemont’s standard model RA11. A robust unit from top to bottom, it has a welded steel base and uses plate-type construction. The shafts are made from high-strength alloy steel, carburized, and ground. It features precision tapered cup/cone bearings that can bear both radial and axial loads. The hardened gears run in an oil bath for smooth, quiet, trouble-free operation.
While the standard RA11 has 12 stations, 2-inch shafts, and 10-inch roll spacing, the RA11-18 was customized to 18 tooling stations, 1.50-inch shafts, and 14-inch roll spacing. The other critical dimensions on the RA11-18 are the same as on the standard model. These include 11-inch horizontal centers and vertical centers that are adjustable from 6¼ to 7½ inches. It processes mild steel, in thicknesses from 0.031 to 0.035 inch, at speeds up to 100 feet per minute.
T&H Lemont provides mills, components and services for making tube, pipe, and profile. Services include tooling designs, mill alignments, mill rebuilds, and operational troubleshooting. System components designed and built by T&H Lemont include strip accumulators, edge preparation equipment, entry equipment, seam orientation stands, weld boxes, bead scarfing systems, straighteners, cutoffs (saw and shear), and dedimplers. Nearly all of these subsystems can be designed with quick-change capability.
The company also makes consumables such as shafts, blades, and jaws.
