Perforation /

Here is another in our line of innovative products for use with the Scheffer inline rotary cutter:

The molded perforation (Snap-Pak) knife system. Our molded, perforation knives can be made to incorporate any combination of cut and perforation rule with some of the more popular configurations pictured above. Paper Benders Supply, Inc. is the exclusive manufacturer of this innovative system that saves make ready time and labor costs. Operators save valuable time as they do not need to mount cutting knives into holders. Made from high strength, flexible polyurethane, all chip knives are molded with the correct spacing which eliminates the possibility of operator spacing errors.

Molded Snap-Pak steel rule knives for use with the Scheffer inline rotary cutter have these benefits and features:

  • Manufactured for any combination of chop (single) / perf or chip (double) / perf knife
  • Designed to simplify setup and dramatically reduce make-ready time
  • No need for separate spacer blocks between knife mount
  • No need for “special" mounting hardware - knives and shells mount with standard cap screw, lock
  • washer and brass dovetail nut.
  • Can be reused for multiple jobs
