Note: This presentation shows numerous concepts and<br />
innovations that illustrate many trials to reduce labor for<br />
stripping, some that can be used now, all in hopes of advancing<br />
more techniques for improved methods.
A perplexing question:<br />
How many grades?<br />
4 Grades?*<br />
3 Grades?*<br />
2 Grades?<br />
1 Grade?<br />
*Note:<br />
Current Marketing Contracts require 4 or 3 grades.
