Rotary Slitters

Circle is an independent leader for rotary slit board. 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.

Equipment Highlights:

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


Round Corner Finishing

Circle’s round cornering equipment gives clean accurate round edges to the panels we produce. Typically used in 3-ring binders for vinyl sealed or laminated covers our round corner board is held to the same high quality standards as our other board products. Any of our board grades can have a round corner finish for any application.

Equipment Highlights:

  • 3/8″, 1/4″, 5/16″ Corners
  • Clean Edges
  • Any Board Grade


Groove Board

Circle’s Grooving capability goes beyond the industry standard “unitized board” or “routed board” and produces a product with a higher level of quality and performance.  Our “V” groove technology is used in specialty packaging applications by companies that want a sharp edge to promote their brand and separate themselves from the crowd.  Circle also has the capability to produce a wider “Flat Bottom” groove that can be used for products that may require a softer look.  Our unique process produces the cleanest and deepest groove available for maximum flexibility, sharp or soft looking edge.

Other applications include: carpet/flooring sample books, digital print canvas frames, chipboard easels, box wraps, slip case, binders, custom marketing pieces, or specialty grooved projects.

Equipment Highlights

  • Can groove .040 pt. – .140 pt.
  • Up to 39” wide with up to 8 Grooves
  • Cleanest and Deepest Groove available


Guillotine Trimming

Circle produces over 1 million chipboard pads a day!  Our cut to size chipboard pads are the cleanest in the industry and our cutting methods produce the most accurate and square chipboard pads possible.  With up to an 85” cutting blade there are very few jobs that Circle can’t handle on our trimmers.

Equipment Highlights

  • Up to 85” cutting blade
  • Trim calipers from .010-.300 pt.
  • Over 1 million chipboard pads/day


Sheet Laminating

Our ability to create Pasted Chipboard allows our customers to create unique packaging solutions for their applications. Heavy caliper chipboard is a great “Green Alternative” to using wood or other materials and Circle Inc. can produce board as heavy as your application requires. We can also produce Cross Grain sheets that provide excellent stiffness in each direction of the sheet. The even glue application combined with the 62” press section gives the flattest most reliable pasted chipboard due to curing under pressure.

Equipment Highlights

  • Unlimited Caliper Range
  • “Green” Alternative to Wood
  • Cross-Grain capabilities
  • 62” Press Section


  • Unlimited Caliper Range
  • Excellent “Green” Alternative to Wood
  • Cross Grain Laminating
