TOP ROLLS.
6. See that your top rolls are kept in good condition. Look them all over once a month if that will do, if not look them over oftener. New rolls should always be put in the front, poorest ones in the back. New rolls should always be calipered at each end; if they do not caliper the same at each end of the roll, the roll should not be used, as it would spoil the yarn, and spinners could not keep up their ends. New rolls should be oiled when they are put in to run. Neck of front rolls should be oiled morning and noon. All of the rolls should be oiled once a week. The weight should be the same on all top rolls. In order to do this your saddles must be all alike, and must not hug the neck of the roll. Stirrups should be all of the same length and style. The levers should be all of the same length and style; and weights should be all of the same heft. Stirrups must clear the rolls, and use double saddles. Shell rolls should be cleaned and oiled once a month, with lard oil. Use vinegar with one-third water to clean top rolls. Roller hooks should not be used on steel rolls.
