DREISTERN - Number one in roller forming and welding


Production of profiles, using laser welding and start-stop® technology


Laser welding with the use of a start-stop® technology

DREISTERN developed the first profile forming line with the use of a start-stop® technology 30 years ago. Such technology is unique and enjoys its well-deserved success. The start-stop technology allows for including of the unlimited number of post-production processes, such as perforation, stamping, compressing, bending, punching, and other technologies in a production line. The result of such technology use is production of a finishing profile, manufactured in one piece. Secondly, it doesn't require expensive post-production processes, thus significantly facilitating assembly and connection operations. The process of profiles roll forming stops in a special position for a short period of time in the process of start-stop handling. It is necessary to complete all necessary operations. The profile is moved by the rollers, moving at the full speed, immediately after completion of the aforesaid operations. Addition of laser-welded profiles to the production process helped the company to perform a "quantum leap" in the sphere of this technology development. Nowadays, laser-welded profiles can be simply produced with the use of a start-stop technology.

Used for production of:

  • Ultra-light profiles for the automobile industry
  • Body parts for vehicles with certain characteristics of accidents protection
  • System profile, used for various applications
  • Separators of ball bearings / frame profile / shelving racks



  • Possibility to include virtually unlimited number of operations in the process of the profile roller forming
  • High speed roller forming of the average profile even with a short length
  • Exact positioning of the line (start-stop ®) with high tolerance of post-forming operations
  • Secondary preparatory operations are excluded, simplifying the assembly process
  • Additional nodes are built into the line with no additional costs
  • Cost reduction: no need to equip the line with a mobile machine for cutting of the continuously moving material


We provide:

  • Prototypes of the first and small series
  • "Turnkey" constructions for manufacture and assembly
  • Semi-automatic lines for economically sound profiles production in small and medium quantities
  • Fully automatic lines for production of large quantities of profiles
