Roll Dimpler

Welker Auto-Indexing Dimpler

Welker Auto-Indexing Dimpler prevents sheet metal blanks from sticking together in stamping operations by producing small dimples in the trim edge that automatically index with the action of the press.
  • 7 indexes per revolution minimizes potential for dimple nesting
  • Protects dies by minimizing potential for multiple blank feeds
  • Can correct fan stack effect on tailor-welded blanks
  • Requires no air, hydraulic or electrical connections
  • Actuated by gas spring for superior reliability
  • Increases efficiency of part grippers
  • Suitable for aluminum or steel
