摘要： A special yarn spinning apparatus adapted for use in a spinning machine includes a plurality of apron draft devices that are configured to switch fiber bundles to be fed, respectively. The special yarn spinning apparatus further includes a joining device and an anti-twist device. The joining device joins a training end of the fiber bundle fed from at least one of the apron draft devices which has operated before switching the feed and a leading end of the fiber bundle fed from another of the apron draft device which has started after switching the feed. The anti-twist device holds and delivers the fiber bundle at a position downstream of the joining device to prevent propagation of twist from a twist device to the joined fiber bundles in the joining device.

摘要： A spinning machine (1) includes a roving-supply stop device (3) that includes a roving-supply stop member (30, 32) shifted between a first position for allowing the supply of a roving (9) to a drafting device (2) and a second position for stopping the supply of the roving (9) to the drafting device (2), and a holding member (38) for holding the roving-supply stop member (30, 32) in the first position against an urging force of an urging member (34). The spinning machine (1) further includes a return mechanism (41, 71) including a moving member (42, 72), a drive part (43, 73a, 73b, 74), and a return member (44, 44a-44e, 75). The return mechanism (41, 71) engages the return member (44, 44a-44e, 75) with two or more roving-supply stop members (30, 32) in the second position when the drive part (43, 73a, 73b, 74) moves the moving member (42, 72) together with the return member (44, 44a-44e, 75) in a base longitudinal direction (X), and returns the two or more roving-supply stop members (30, 32) from the second position to the first position through the engagement of the return member (44, 44a-44e, 75).

摘要： A drafting device includes a pressing portion that increases the contact pressure between a back bottom apron and a back top apron without changing the contact pressure between a middle bottom apron and a middle top apron. This does not hinder feeding of fibers of a first roving that are held by a front bottom roller and a front top roller. Additionally, separation of fibers from a second roving and breaking of the second roving may be limited between the holding position of the front bottom roller and the front top roller and the holding position of the back bottom roller and the back top roller.

摘要： In a method for controlling a drafting device of a spinning frame, the drafting device includes a front bottom roller 12, a middle bottom roller 13, a back bottom roller 14, and motors (15, 16a, 16b, 17a, 17b) that independently drive the bottom rollers. The method includes changing a break draft ratio of the drafting device in a deactivation process of the spinning frame so that a load torque of the drafting device is smaller than when the break draft ratio is set to a value for normal operation to limit untwisting of the bottom rollers. The method further includes changing a main draft ratio when a fiber bundle, which has passed by the middle bottom roller 13 during a period the break draft ratio is changed, passes by the front bottom roller 12, to cancel influence on the fiber bundle of the changing in the break draft ratio.

摘要： A method for controlling a pot spinning machine (1) includes spinning a yarn (20) supplied from a drafting device (2) in a pot (5, 5-1, 5-2, 5-3) of each of spindles (61, 62, 63), rewinding the yarn (20) spun in the pot (5, 5-1, 5-2, 5-3) onto a bobbin (25), and inspecting each spindle (61, 62, 63) to determine whether a remaining yarn exists in the pot (5, 5-1, 5-2, 5-3) between the end of the rewinding performed after the spinning and the start of next spinning. The method further includes starting a roving-supply stop device (3) of the spindle (61, 62, 63) that is determined in the inspecting as the spindle in which the remaining yarn exists to prevent the yarn (20) from being spun in the pot (5, 5-1, 5-2, 5-3) in the next spinning.

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).
