Lunn bar, fitted parallel to the mill rolls and positioned so that the operator works over it. The Lunn bar has proved effective in reducing the number of fata l and serious maiming injuries at two roll mills from their historical level of about 20 per year in the 1950s 60s,
The Two Roll rolling and curving machine is a machine that is aimed at the high production market. Since each diameter part must have an individual sleeve or shaft developed to produce this part, it is not feasible to use this style of machine in an atmosphere where there are a very low number of parts produced and a very high number of sizes.

The following is the working principle drawing of symmetrical 3 roll bending machine. Driven roller, is driven by motor and reducer, which rotates in the same direction at the same speed (or in the opposite direction). After the two ends roll out a certain length, then cut off the remainder (also known as the straightline segment).
The rolling process is shown in Fig. : Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
