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： 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 bobbin replacement device (40) for a pot spinning machine (1) is configured to replace a full bobbin (30) with an empty bobbin (30). The pot spinning machine (1) includes a pot (16) and a fixed cover (18) surrounding the pot (16) and having an opening (28) that opens downward. The bobbin replacement device (40) includes a drive mechanism (46, 48), a movable portion (42, 44), and a lid (50). The movable portion (42, 44) is moved in a predetermined direction (A, B) by the drive mechanism (46, 48). The lid (50) is attached to the movable portion (42) such that the lid (50) is moved together with the movable portion (42, 44). The lid (50) is placed at a close position to close the opening (28) of the fixed cover (18) and placed at an open position to open the opening (28) of the fixed cover (18) according to the movement of the movable portion (42, 44) by the drive mechanism (46, 48).

摘要： A pot spinning machine (1) includes a pot (16), a yarn introduction pipe (14), a fixed cover (18), and a lid (50). The pot (16) has an opening (26) that opens downward. The yarn introduction pipe (14) introduces a yarn (25) into the pot (16) and has a yarn outlet (14b) from which the yarn (25) is discharged into the pot (16) at a bottom end of the yarn introduction pipe (14). The fixed cover (18) surrounds the pot (16) and has an opening (28) that opens downward. The lid (50) opens and closes the opening (28) of the fixed cover (18). The lid (50) has a projecting portion (52) that is inserted into the pot (16) through the opening (26) of the pot (16) when the opening (28) of the fixed cover (18) is closed by the lid (50). The projecting portion (52) guides the yarn (25) discharged from the yarn outlet (14b) of the yarn introduction pipe (14) at yarn cutting to an inside wall (29) of the pot (16).

摘要： A bobbin replacement apparatus (20) of a spinning machine includes a first bobbin support axis (J1) extending in parallel to a vertical axis (J5), a second bobbin support axis (J2) that is disposed at a position shifted from the first bobbin support axis (J1) in a horizontal direction, a holder axis (J3),and a lift axis (J4). When the lift axis (J4) and the second bobbin support axis (J2) are disposed in parallel, the angle between the holder axis (J3) and the lift axis (J4) is maintained at a first angle. When the lift axis (J4) of the lifting mechanism (25) is tilted by the tilting mechanism (26), the angle between the holder axis (J3) and the lift axis (J4) is maintained at a second angle, and the holder axis (J3) and the second bobbin support axis (J2) are disposed coaxially.

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.
