Roll Forming: Automatic Top-Shaft Positioning

 
Driven Roll Stand with SPA and ATP Features

The Yoder ATP system is designed to be an extension of Yoder's popular Single-Point Adjustment (SPA) feature to automatically and repeatedly position the top roll shafts of each driven roll stand during mill setup.


  • Since the system does not rely on pre-set shaft positions, the program does NOT need to be changed when the rolls are reground.
  • The motors can be moved without resistance when idle. This means that for on-the-fly adjustments, each stand can still be adjusted by hand as easily as with only conventional SPA.
  • System utilizes off-the-shelf components with no custom hardware so that the system can be easily maintained during the long-term.
  • System can be retrofitted to any mill.
  • Good alternative to rafted mill design, especially on smaller machines where roll tooling can easily be exchanged by hand.
