摘要
A ring spinning frame has a drafting station with a variable-length cage to alter the length of the upper belt or the position of a roller. The distance (L) from the clamping line between the first pair of drafting rollers (62, 71) and the previous set of rollers (55) is adjustable. A ring spinning frame has a drafting station with a variable-length cage to alter the length of the upper belt or the position of a roller. The distance (L) from the clamping line between the first pair of drafting rollers (62, 71) and the previous set of rollers (55) is adjustable. The distance (L) is between 3% and 21% greater than the length of the longest fiber in the incoming material (54). In the case of a two-inch fiber the gap (L) is 53-57 mm. The fiber open transfer zone between the mid roller pairs (55) and first pair of drafting rollers (62, 71) is optimized by an upper belt cage (77), in conjunction with adjustment of the upper rollers.
