Traverse Winding Lines

Traverse winding is the technology of winding narrow metal strips, with the goal of producing evenly cross windings on a predetermined spool’s width or directly on the rewind reel’s mandrel.

Precision traverse winding lines for metal strip production

Precision traverse winding lines are used where wide coils are slit into narrow strips and quickly wound into a spool to maximize the amount of material with minimal volume. Depending on the customer’s requirements, a slitting line can often be equipped with multiple traverse winders.

In a stand-alone system, individual coils are unwound, joint welded at each end, and then oscillating wound with the traverse winder.

Depending on requirements and material, recoiling is performed directly into the rewinder’s mandrel, on metal/cardboard cores, or into spools. We can further customize these lines by integrating secondary processes such as thickness measurements, precision straightening, edge conditioning, or static oiling devices.

Advantages of a b+s traverse winding line

  • exact winding pattern with increasing coil diameter due to high-performance winding algorithm
  • very good edge build-up from start due to the initial waiting angle,
  • very stable, uniform edge build-up due to automated program for the offset angle
  • fully automatic calculation of the optimum winding step
  • perfect winding pattern – independent of the line operator
  • reduction of setup times through innovative automation solutions as well as fast line speeds
  • high-precision cutting quality due to clearance-free slitter shaft bearings
  • minimization of the burr height with a simultaneously high number of strips due to the smallest possible deflection of the cutter shafts
  • experience in processing ultra-high-strength materials with a tensile strength above 1,500 N/mm² (0.22 pound/square inch) with yield strength above 1,100 N/mm² (0.16 pound/square inch)
