A fastening process uses multiple rollers to smooth material into a solid form.
The process can be used in place of other fastening methods. It is suitable for forming large-diameter and thin-wall materials, as well as rolling or closing a lip. It can also be applied in situations where the rollers articulate as well as rotate, allowing for access into grooves and other areas.
Crimping and pressing can be simplified using the roller forming process. Forming a curl or lip with the technique can take less than 20% of the force normally required for straight crimping or pressing. It also allows for precisely controlled cold forming and simultaneous formation of inside and outside diameters.
Roller forming can be used in work cells and automated assembly operations. The system is strong enough to use with metal and aluminum
parts and versatile enough for appearance-sensitive plastic parts. Medical applications include joints on surgical instruments, circuit boards, and casters.
