ABSTRACT:
In a ring spinning frame provided with two parallel alignments of bobbin hangers, a plurality of roving guides is arranged in an alignment at an intermediate position between the two alignments of bobbin hangers, wherein a first group of roving guides is formed by roving guides alternately positioned in the roving guide arrangement and a second group of roving guides is formed by the remained roving guides thereof, an improved creel mechanism for relatively displacing the first group of roving guides and the second group of roving guides whereby a first intervening space between two adjacent roving guides and a second intervening space between two adjacent roving guides are alternately formed along the alignment of the roving guides, wherein the first intervening space ensures a free passage of a full packaged roving bobbin but the second intervening space does not permit a free passage of the full packaged roving bobbin, the above-mentioned formation of two intervening spaces being created alternately, at each intervening space between two adjacent roving guides, by the reciprocal motion of the displacing mechanism.
