Abstract
A method is described for drafting woollen slivers on a ringframe on which it was possible to vary many factors. It was found that the only factors that affected the irregularity were the draft and the twist inserted.
Separate experiments were performed to assess the effect of draft and twist. On the whole, the results obtained agreed with the findings of Martindale and his co-workers for the drafting of woollen slivers on the mule. Certain differences were noted, however, and it is suggested that these may be due to the fundamental difference between the frame and mule methods of drafting woollen slivers.
