Variable up to
Cartons per minute

The Vari-Straight is a straight-line closer for tri-seal topload cartons. It features Kliklok’s patented variable pitch technology, which uses pop-up lugs to create infinitely variable flight centers. This combines the benefits of lugged carton control and random infeed timing in a full servo motor platform. The constant carton control eliminates the inherent slip and timing issues of lugless carton closers.

  • Patented pop-up lug technology for constant carton control
  • Easy operation with Insight® color touchscreen HMI
  • Absolute cover registration with prefold wheel
  • Repeatable changeovers with CheckPoint system
  • Sanitary IP65 stainless steel construction
