NEOPRENE RUBBER
Or Polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene. Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. Also used to coat doctor or metering rolls.
NICKS
Small relief in cut edge of rule to interrupt cut. Used to hold blanks together after die cutting.
NON-METALLIC DIE CUTTING
Refers to the diecutting of all soft to semi-rigid materials such as leather, paper, plastics, fabrics etc. Not the cutting or blanking of metal parts.

NOTCHES
(1) Indentations in the bottom of rotary cutting rule to facilitate curving of the rule to conform to the die cylinder.
NOTCHING
(1) Cutting out a section on the back edge of rule to fit over a bridge left in the dieboard. Bridging sometimes used interchangeably. (2) Cutting or forming a notch into the edge of a cutting blade for use as a location indicator to match different component parts together for final assembly.
NUMERICAL CONTROL
The use of X, Y and Z coordinate data to position a two or three axis machine, such as a laser table mill, sample maker, or counter cutter.
