Book Binding Capabilities

Rotary Board Slitting

​Circle is an independent leader for rotary slit board in the book and 3-ring binder market. Our rotary slitting operation is the most accurate in the industry producing panels as small as 4″ and as large needed. The machines run calipers ranging from .055 pt. to .150 pt. and it is the most accurate way to convert board with tolerances held on squareness to .00075″. We ensure these tolerances are maintained by visually inspecting and checking each stack of board for dimension and squareness. This constant quality check means that only high-quality product ships to our customers.

 Equipment Highlights:

  • Caliper Range from .055 pt. to .150 pt.
  • Tolerances held to .00075″
  • Inspect In-Feed and Down Stack
