TWIST OF YARN.

37. To know how to get the exact twist in yarn. Have your roll belt tight, and band also. Count the revolutions of the spindle to the rollers once. Divide that by the circumference of the roll, which is 3-14/100 inches. Example. Say 86 turns to the rolls once. (3-14/100) 86.00 turns, (27-38/100) twists to the inch.
