DRAFT CALCULATIONS.
The above figures are for Total Draft up to and including the 3-in. dia. Calender Rolls. When Graduated Pitch Metallic Rolls are used, and it is desired to figure drafts between them, the following equivalents are approximately correct:
1-3/8-in. dia. Roll, 32 pitch, taken as 11/6-in. or 1.83-in. dia.
1-1/4-in. dia. Roll, 32 pitch, taken as 10/6-in. or 1.67-in. dia.
1-1/8-in. dia. Roll, 32 pitch, taken as 9/6-in. or 1.50-in. dia.
1-in. dia. Roll, 32 pitch, taken as 8/6-in. or 1.33-in. dia.
1-1/8-in. dia. Roll, 16 pitch, taken as 10/6-in. or 1. 67-in. dia.
1-in dia. Roll, 16 pitch, taken as 9/6-in. or 1.50-in. dia.
