Abstract
Abstract A system for cutting curvilinear patterns in strippable films with a high speed computer controlled flat bed plotter having a diamond point cutter positioned in the plotting head. The scribe pressure is set between 200 and 300 grams with the plotter set to drive the plotting head at a speed between 20 and 30 inches per second and with the head acceleration set between 0.4 G's and 0.7 G's.

Claim 1
Independent Claim
106 words
The process of cutting curvilinear patterns in the plastic layer on a strippable material with a computer controlled X-Y flat bed plotter wherein the computer is programmed to move the plotting head over the strippable material with desired pattern, comprising: placing the diamond point cutter in the plotting head of the flat bed plotter; adjusting the scribe pressure on said diamond point cutter to between 200 and 300 grams; moving the plotter head over the strippable material in response to the computer command at a head speed of between 20 and 30 inches per second with a plotter head acceleration between 0.4 G and 0.7 G.
