As corrugated packaging continues to evolve, more demands are being placed on diemakers to produce dies that cut everything from F-Flute to Triple Wall. We understand that proper rule selection plays a vital part in the successful diecutting of any grade of corrugated. We offer fourteen styles of rotary cutting rule; each specifically engineered to provide optimal diecutting performance.
Every style of rule designed is evaluated to see how it performs using the following criteria:
- Pressure required to cut a given material.
- Penetration into the blanket.
- Appearance of the edge after diecutting.
- Longevity (wear) of the rule.
It is very easy to design a product that will provide maximum performance on any one of these variables. The challenge comes in engineering products that excel in a given area while performing well on the other four elements.
There are four characteristics of all rotary rules that determine how well a product will perform:
- Pitch - Pitch refers to the number of teeth per inch. Generally speaking less teeth per inch will cut with less pressure while more teeth per inch will result in increased pressure.
- Geometry of Tooth - The geometry or shape of the tooth will affect both the cutability and bendability of the rule.
- Depth of Gullet - Gullet depth is a key factor in determining the longevity of the rule.
- Hardness - The temper of the rule will determine the formability of the rule as well as affect longevity
- Straight rule is available in coils, 30", 36", 48" and one meter lengths.
- Standard curvatures: 37 1/2" (257 mm), 38" (279 mm), 50" (360 mm) and 66" (487 mm).
- Standard back notch: N1, 1/2" (12.7 mm) centers, 1/2" (12.7 mm) deep.
