<p>System with 'ring - traveller' assembly for spinning frames or doubling frames, whereby the system comprises an outer ring (10) and an inner ring (11) positioned on the same axis and creating between them an annular gap (24), the outer and inner rings (10, 11) comprising annular protrusions (13, 14) and/or grooves (23, 29), and the outer ring (10) is substantially secured to a ring rail (26), while the inner ring (11) is substantially anchored by connecting bracket means (12) positioned below the gap (24), the traveller (15) having substantially a circular form and including a through central hole (16) for the passage of a thread (17), there being defined in cooperation with the annular gap (24) at least one rolling track associated with the outer ring (10) and having its plane of positioning parallel to the axis of the spindle, and also at least two annular tracks (28) positioned respectively on the inner ring (11) and on the outer ring (10) and lying on respective planes positioned in the vicinity of planes perpendicular to the axis of the spindle, the annular tracks (28) and the traveller (15) defining points of substantial contact (A, a; B, b; C, c; D, d) cooperating with the vicinity of the edges of the gap (24) and with the vicinity of the circumferential periphery of the traveller (15).</p> |
