摘要:
A yarn traverse apparatus which prevents adjacent blades from interfering with each other and breaking even if blades of any of traverse mechanisms are out of phase and which allows the traverse mechanisms to be installed and removed easily. The yarn traverse apparatus includes a plurality of traverse mechanisms arranged so as to be adjacent to one another with respect to a plurality of juxtaposed bobbins. Each traverse mechanism has a set of two shafts arranged upstream of a corresponding bobbin. The two shafts are orthogonal to a shaft of the corresponding bobbin and rotate in opposite directions. Each of the two rotating shafts has blades attached thereto, the blades serving to traverse a yarn. Each traverse mechanism is arranged to form two surfaces of rotation when the blades attached to the set of two rotating shafts rotate. The plurality of such traverse mechanisms are arranged so that loci of rotation of the blades belonging to adjacent sets partially intersect. When yarns are traversed by such yarn traverse apparatus, surfaces of rotation formed by the blades attached to the two shafts of rotation of each of the adjacent traverse mechanisms are uniformly as well as sufficiently inclined with respect to a surface formed by a yarn in a single direction as viewed in vertical directions, so that the surfaces of rotation formed by the blades belonging to the adjacent sets will not interfere with each other.

A draw-texturing apparatus comprises a heating device (3) for heating a running yarn (Y) and a false twisting device (5) disposed downstream of the heating device (3) for imparting twists to the yarn (Y). The apparatus further comprises a twist stopping device (11), disposed in the heating device (3), for stopping the run back of the twists imparted by the false twisting device (5). In the apparatus, drawing point of the yarn (Y) is not adversely affected by false twisting torque or vibration of the yarn (Y), and a textured yarn being free from unevenness in dyeability and having a high quality can be obtained by the apparatus.

A yarn twisting spindle device comprising two spindles (2,6), having yarn introducing holes (24, 25) formed therein, respectively, and coaxially disposed in an axial line rotatably in opposite directions, for twisting a yarn passed through the introducing holes. An end (2b) of one (2) of the two spindles is formed in a cylindrical portion and has outer annular members (7a) fitted inside thereof. An end (6a) of the other spindle (6) is formed in a shaft portion (6) and has inner annular members (7b) fitted outside thereof. Balls (8) are disposed between both the annular members (7a, 7b) so as to rotatably support the two spindles, and a prohibiting member is disposed for prohibiting revolution of the balls.

An apparatus for continuously winding a yarn (Y) comprises feed rollers (FR) for feeding the yarn (Y) at a predetermined speed, a reversing roller (15) for substantially reversing a moving direction of the yarn (Y) fed from the feed rollers (FR), and a take-up device (W) for taking up the reversed yarn (Y). A unit is portable and has the feed rollers (FR), the take-up device (W) and the reversing roller (15) integrally mounted thereon, the feed roller means (FR) is disposed above the take-up device (W), and the reversing roller (15) is disposed under the take-up device (W).

A machine frame (1) has a traverse device (6) and a frame (5) having a contact roller (7) movably mounted thereon. A first slider guide member (20) is substantially vertically disposed below the contact roller, and a second slider guide member (17) is pivoted on a shaft (18) spaced from the lower end of the first slider guide member (20), sliders (13, 14) are slidable along the slider guide members (17, 20), carriers (15, 16) are connectable with and detachable from the sliders (13, 14), and the carriers (15, 16) have bobbin holders (8, 11) rotatably mounted thereon. The bobbin holders (8, 11) move winding position, doffing position and stand-by position while the bobbin holders (8, 11) and carriers (15, 16) are transferred between the sliders (13, 14) of the slider guide members (17, 20).
