    • A sewing needle is used in a sewing machine. The sewing needle has a working portion with a needle eye and a region which tapers into a needle tip. The needle eye passes through a needle body in a transverse direction perpendicularly to a longitudinal axis of the needle body. A twist groove is recessed in a front face of the needle body relative to the outer contour of the needle body, the twist groove extending in the direction of the needle tip from the needle eye. The twist groove is formed by a thread groove. The twist groove is preferably symmetrical relative to a first longitudinal central plane spanned by the longitudinal axis and the transverse direction. The thread groove has a groove portion adjacent to the needle eye and two end portions, each having a thread groove opening, remote from the needle eye.
    • 在缝纫机中使用缝纫针。 缝针具有针眼的工作部分和逐渐变细的针尖的区域。 针眼在与针体的纵向轴线垂直的横向上穿过针体。 扭转槽相对于针体的外轮廓在针体的前面凹陷,扭转槽从针眼的针尖方向延伸。 扭转槽由螺纹槽形成。 扭转槽优选地相对于由纵向轴线和横向方向跨越的第一纵向中心平面对称。 螺纹槽具有与针眼相邻的槽部和两个端部,每个端部具有远离针眼的螺纹槽开口。

    • A manually operable needle threading device comprises a housing having a recess for positioning the eye of a needle to be threaded in alignment with the path of a displaceable thread pusher member in the housing, whereby displacement of the pusher member from a retracted to an extended position pushes a portion of a thread between the needle and pusher member through the needle eye. The pusher member displaces the portion of thread between gripping fingers on the housing which hold the thread portion upon displacement of the pusher member from the extended to the retracted position. The portion of thread remains attached to the threading device upon separation of the needle therefrom until a loose end of the thread passes through the needle eye to complete the threading operation, after which the thread portion is released from the threading device. In one embodiment the housing is of pistol-like configuration facilitating handling and operation of the threading device.
    • 一种可手动操作的针穿装置包括一个壳体,该壳体具有用于定位针眼的螺纹的凹槽,所述孔的螺纹与可移动的螺纹推动器构件在壳体中的路径对准,由此推动器构件从缩回位置到伸出位置 通过针眼推动针和推动器构件之间的线的一部分。 当推动器构件从延伸到缩回位置的位移时,推动器构件将保持螺纹部分的壳体上的夹持指状物之间的部分螺旋移位。 螺纹部分从针头分离时保持附着在螺纹装置上,直到螺纹松动的一端通过针眼完成螺纹操作,此后螺纹部分从穿线装置中释放出来。 在一个实施例中,壳体是类似手枪的结构,便于穿线装置的处理和操作。

    • A looper for a tufting machine for producing cut-pile has a base portion, a forward hook-shaped end and a yarn engaging portion around which a loop of yarn is formed extending between the base portion and the forward end, the yarn engaging portion having smooth contours adjacent only the forward end of the looper, the remainder of the length of the yarn engaging portion having a cutting edge formed thereon for effecting the cutting upon cooperation with an independently operable cutting blade of at least one of a series of accumulated loops collected on the yarn engaging portion. Thus, any catching, cutting or breaking of the loop of yarn before being cut by the cutter blade is avoided.
    • 一种用于生产切割绒头的簇绒机的活套具有基部,前钩形端和纱线接合部分,在基部和前端之间形成有一条纱线环绕的纱线,纱线接合部分具有 平滑的轮廓仅与弯针的前端相邻,纱线接合部分的长度的其余部分具有形成在其上的切割边缘,用于在与一系列累积的回路中的至少一个的独立可操作的切割刀片协作时进行切割 在纱线接合部分上。 因此,避免了在切割刀片切割之前纱线环的任何捕获,切割或断裂。
