摘要： A pot spinning machine includes a pot (1) that has a downward-facing opening (1a) and rotates, a yarn guide (5) that is inserted into the interior of the pot (1) through an attachment hole (1c) formed in an upper portion of the pot (1) in order to guide yarn (4) into the interior of the pot (1), and a yarn guide rail (6) that holds the yarn guide (5) and is capable of moving in an elevation direction, wherein the yarn guide (5) is held by the yarn guide rail (6) via a yarn guide holder (7), and a holding force (P1) of the yarn guide holder (7) is smaller than a resistance force (P2) that acts on the yarn guide (5) when a wound-up part (Y) formed as a result of the yarn (4) being wound around the yarn guide (5) contacts a non-elevating member (8, 2a). As a result, force generated when the yarn wound around the yarn guide (5) contacts another component can be alleviated even when the yarn (4) undergoes yarn guide wind-up.

摘要： A ring (11) of a spinning machine includes a sliding surface on which a traveler (12) slides, wherein the spinning machine is configured to wind a yarn (Y) through the traveler (12). The sliding surface has a texture having a plurality of recesses and a plurality of projections. Each projection has a curved shape and is located between adjacent recesses. The projection has a curvature radius of 40 to 400 µm. A method for manufacturing the ring (11) includes a step for forming the sliding surface. The step for forming the sliding surface includes: a first step for forming a plurality of dimples in a surface of the ring (11); and a second step for rounding a peripheral edge of each dimple and/or a portion between adjacent dimples.

摘要： A ring-traveler device with no liquid lubrication of a ring type spinning machine includes a ring 11 and a traveler 12 that is slidable along the ring. The ring-traveler device has a plurality of first recesses 15 and a plurality of second recesses 16 formed in at least one of sliding surfaces of the ring and the traveler. Each first recess has a width between 10 and 100 µm and is formed by an opening edge 15A and an inner surface 15B, Each second recess 16 has a width smaller than each first recess 15. At least one of the second recesses extends across at least one of the opening edges and the inner surfaces of the first recesses.

摘要： A bobbin (25) and rewinding means are inserted into a pot (12) through an opening (23) of the pot (12). Next, a contact step (S4) is performed. Respective elongated members (73) move in a horizontal direction. In a pot (12) in which yarn breakage has been detected, the elongated member (73) is lifted up in advance, and therefore the elongated member (73) is pressed into contact with an inner wall (22) of the pot (12). Next, a moving step (S5) is performed. The bobbin (25) and the elongated member (73) are raised. As a result, a tip end of the elongated member (73) is pressed into contact with a cake lower end (28b).

摘要： A ring (11) for a fine spinning machine is used in the fine spinning machine for winding a yarn through a traveler (12) sliding on a sliding surface of the ring (11) in a dry state. The sliding surface of the ring (11) is covered by chrome plating (13). In the chrome plating (13), a ratio of emission intensity of hydrogen atoms (H) to emission intensity of chromium atoms (Cr) determined by glow discharge optical emission spectrometry (GD-OES) is 0.1 or more.
