Micro-perf is special, very fine perforation that tears clean when pulled apart. This perforation is used for stocks that need perforations and must be fed again through copiers and printers.
There are kits available for both 7/8” and 1-1/8” shaft sizes. The key to whether your machine can utilize a micro-perf is dependent upon if your machine has adjustable slitter shafts. The adjustment occurs in the center to center distance between the shafts. Because the micro-perf crushes the paper between a blade and a hardened metal ring, a fine adjustment is necessary to prevent tearing the paper or damaging the blade.
There is now an adjustable slitter shaft assembly available for 714 folders which can allow your table top machine to run a micro-perf assembly. This will work on certain 714 parallel machines starting with the “XE” in 1991. You can contact us to find out if your particular machine is capable of this upgrade.
