The Relation between Spring Irregularities of the Spring-type Cradle and Yarn Irregularities

We tried to find the relation between spring irregularities of the spring-type cradle and yarn irregularities in spinning frame， and got the following results. Regular cradle springs can spin regular yarn. Irregular cradle springs spin comparatively regular yarn unless irregularities are on one side in both rollers. When one roller has an irregular spring， it' s cradle spins the most irregular yarn.
