For example, a single mill may be able to produce metal studs of different web (e.g. 3-5/8" to 14 inches), flange (e.g. 1-3/8" to 2-1/2") and lip (e.g. 3/8" to 5/8") dimensions, from different gauges (e.g. 20 to 12 GA) of galvanized steel sheet. Roll forming lines can be set up with multiple configurations to punch and cut off parts in a ...

This pushes the top work roll down and the bottom work roll up, which reduces the roll gap in the same manner as running the screws down. To compensate for this, most screw-down control loops include a feed-forward parameter derived from either; an equation of rolling speed, or a value extracted from a lookup table using linear interpolation .

Because chemical reactions are occurring during the process of mixing a rubber compound, the compound often heats up. To help keep the rubber compound cool, often one of the rolls is hollow and can be hooked up to a cooling water line which then allows cool water to flow through the roll, cooling the metal roll and therefore the rubber.

The tank could place demolition charges at heights up to 12 feet. The tank was driven against a wall, and the framework was lowered into the ground against the wall. The tank then backed up 100 feet, laying out an electric detonating cable. The explosives were then detonated by the tank driver. It was the successor to the single-charge device ...
A telescopic handler, also called a lull, telehandler, teleporter, reach forklift, or zoom boom, is a machine widely used in agriculture and industry.
