 7. Process

* The process of roll forming is one of the simpler manufacturing processes. 

1. It typically begins with a large coil of sheet metal, between 1 in. and 20in. in width, and 0.004 in. and 0.125 in. thick, supported on an uncoiler. 

2. The strip is fed through an entry guide to properly align the material as it passes through the rolls of the mill, each set of rolls forming a bend until the material reaches its desired shape. 

3. Roll sets are typically mounted one over the other on a pair of horizontal parallel shafts supported by a stand(s). 

4. Side rolls and cluster rolls may also be used to provide greater precision and flexibility and to limit stresses on the material. 

5. The shaped strips can be cut to length ahead of a roll forming mill, between mills, or at the end of the roll forming line.

8. Production rate of the double layer roof tile machine

*The production rate depends greatly on the material thickness and the bend radius, it is also affected by the number of stations or steps required. 

  

*For bend radii of 50 times the material thickness of a low carbon steel .07 in thick can range from 85 feet per minute through eight stations to 55 feet per minute through 12 stations or 50 feet per minute through 22 stations.

 *The time taken for one product to take shape can be represented by a simple function. 

  

*The function is as follows: Forming time=[ L+n(d)]/V

 where V is the velocity of strip through rolls (fpm), L is the length of the piece being rolled (ft), d is the distance between forming stands (ft), and n is the number of forming stands.

  

*In general roll forming lines can run from 5 feet per minute to 500 + depending on the application. 

  

*In some cases the limiting factor is the punching or cutoff applications.
