The line is suitable for the production of heat treated prestressed concrete wires with plain or profiled surface and low relaxation. Starting with wire rod, the finish product i.e. either coils or bars, is manufactured „in-line“. The finish product conforms to all standards set by German and International standard authorities.

• By means of the very large capstans of 1.200 mm dia. On the drawing machine, the wire will be cooled down in a very short distance of time to abt. 50 to 60° C after leaving of the drawing die; thus providing the required high quality standard of the finish products
• Traversing induction furnace for increase of quality and productivity
• Use of 2 individually driven, V-grooved capstans of 4.000 mm dia. on the stretching unit, thus providing a very straight wire or bar with deflection of
  < 1 mm/m
• Automated operation for the production of coils by use of double take-up collectors with wire cutter installed in front and automatic switch-over after cutting
• Automated operation for the production of bars by use of a looping floor and intermediate accumulator at the bundling station of the bar cutter
• Rectangular and burr-free cutting of bars by using cutter bushes
• Safety devices for the total unit according to UVV/VBG7E and characterizing to CE-standard

• Rod wire pay-off with capacity of 3 coils with incorporated flyer and coil pushing device
• Straight-line drawing machine for max. 5 drafts, capstan dia. 1.200 mm
• Combined drawing, profiling and straightening unit
• Traversing induction furnace with following water quenching section
• V-grooved capstans of 4.000 mm dia. on the stretching unit
• Caterpillar take-off with individual drive of both flat belts
• Wire cutter with rotating cutting knife
• Double coil take-up collectors with automatic switch-over device
• Looping floor with internal width of 4.000 mm
• Bar cutter with cutter bushed and attached bundling station with incorporated intermediate accumulator

• AC three-phase induction motors, water- cooled, i.e. low-noise level, environment-friendly
• Frequency converters SIEMENS with control system „VECTOR control“
• Profi-Bus connection
• Stored-program computer control SIMATIC S7
• Operator panel OP for drawing machine and stretching unit
• Computer control for induction furnace
• Central control desk for the entire line
