	Roll forming basics By: Dan Mennecke, Contributing Writer Roll forming, often called open-section forming, uses successive sets of roller dies to bend a strip of steel progressively until the desired shape is achieved. This process is very similar to traditional tube- and pipemaking, but differs in that it can form more complicated sections. Publish date: January 11, 2005 Tech cell: Roll Forming

	Finding the best splice for your light-duty conveyor: The mechanical fastener option By: Beth Miller and Jim Wingfield, Contributing Writers One way to increase your stamping operation's productivity is to get all the uptime you can from the belt conveyors that carry materials, parts, and finished and packaged products throughout your plant. As moving, wearing equipment, conveyors naturally demand a certain amount of downtime for maintenance and parts replacement. However, keeping those events as infrequent and brief as possible is what uptime is all about. Publish date: May 15, 2003 Tech cell: Coil Processing
	Getting it Straight: Understanding coil straightening in stamping operations By: Bruce Grant, Contributing Writer Before coiled material can pass through a die to produce an acceptable part, it must be straightened. Coil straightening is accomplished by bending a strip of material around sets of rollers that alternately stretch and compress the upper and lower surfaces so that the material's yield point is exceeded.

	Using finite element analysis to roll-form tubes By: Karan Shah, Yingyot Aue-u-lan, and Taylan Altan, Contributing Writers Roll forming is a common method for producing steel tubes. It is a continuous process in which a strip is guided through several sets of rolls that form the strip into the desired shape. After the final shape is achieved, tube edges are welded together to form a closed section. After the welding operation, the tube is sized through another set of rolls to obtain the required diameter. Publish date: October 9, 2003 Tech cell: Tube and Pipe Fabrication
