Staple Conversion

Staple Cutter Blade Pitch & Fibre Length Calculator

Staple length is cut into the reel, not set on a panel. A different length is a different blade set.

Geometric length only. Real staple carries a length distribution around this figure because blade wear, tow tension and pressure roll slip all shift individual cuts — check the finished staple on a fibrograph rather than assuming the pitch.
