Three Knife Trimmer HD1680

The Accutrim HD1680 three knife trimmer is manufactured exclusively for Colter & Peterson. It features extreme flexibility, computer control, and quiet, efficient operation.

Perfect Binder
Key Features
  • Tremendous adjustability: Hydraulic, two-stage infinitely adjustable clamping is paired with an adjustable transport pile clamp to accommodate a wide variety of book dimensions.
  • Quiet, efficient, accurate trimming: A 5-degree swing angle cuts accurately and quietly, extending knife life. The one piece cutting table prevents the bottom book from marking and allows for faster cutting stick changes.
  • Easy, computer-controlled operation: With the help of the PC-based machine control and color touchscreen, one person can operate the Accutrim HD1680 comfortably. The controller remembers multiple jobs, and automatically sets the infeed cartridge, head stop and side knives for each.
  • Fast setup: You can make minor format changes in under 60 seconds, and complete format changes in under 3 minutes.
