    • A toolholder device for a machine tool comprises a holder body driven by a machine tool drive spindle, and a toolholder supported on the holder body so as to be circumferentially and axially displaceable. The holder body and the toolholder are provided with displacement detection elements which are arranged circumferentially in interdigitating relation. A support shaft extends from either member of the holder body and the toolholder toward the other member. The outer surface of the support shaft and the inner surface of a support hole of the other member to be fitted over the support shaft are formed with helical guide grooves which are opposite to each other and slopingly extends with respect to the rotational axis of the toolholder device. Balls are interposed between the opposite guide grooves to form a displacement translation mechanism which converts a rearward axial displacement of a tool and the toolholder due to overload axial thrust into a circumferential relative displacement between the adjacent detection elements. The relative displacement of the detection elements is detected by a detection unit which issues a warning signal. A compression spring in the device resists the axial displacement of the toolholder unless the axial thrust exceeds a predetermined value.
    • 用于机床的刀架装置包括由机床驱动主轴驱动的保持器主体和支撑在保持器主体上以便沿周向和轴向移位的刀架。 保持器主体和刀架设置有位移检测元件,该位移检测元件以交错关系周向布置。 支撑轴从保持器主体的任一构件和刀架朝向另一个构件延伸。 支撑轴的外表面和待装配在支撑轴上的另一个构件的支撑孔的内表面形成有彼此相对并相对于刀架的旋转轴线倾斜延伸的螺旋引导槽 设备。 球置于相对的引导槽之间以形成位移平移机构,该位移平移机构由于过载轴向推力转换成相邻检测元件之间的周向相对位移而转换工具和刀夹的向后轴向位移。 检测单元的相对位移由发出警告信号的检测单元检测。 装置中的压缩弹簧抵抗刀夹的轴向位移,除非轴向推力超过预定值。

    • An apparatus for producing special yarn made of a fiber strand in which a number of fibers are randomly arranged along the lengthwise direction thereof, in which special yarn at least one of the yarn structural parameters, e.g., yarn count number or number of twist, changes along the lengthwise direction of the yarn.A pattern of change of the parameters of the yarn structure with respect to the length of the special yarn to be produced is stored in a central processing device, while a spun length of the special yarn is measured by a sensor. The yarn structural parameters are changed to correspond to the pattern set to the central processing device and the special yarn is produced by the yarn forming device using another central processing device of the spinning frame.This apparatus can be used for a ring spinning frame, an open end spinning frame, a fasciated yarn spinning frame, and the like.

    • An ironing apparatus for forming a cup-like metallic article such as an one-piece metallic can body is provided. The apparatus comprises a punch provided on a tip of a ram adapted to reciprocate in the horizontal direction and a plurality of ring dies cooperating with the punch. In the apparatus, the punch reciprocates such that the center of the end face thereof moves along a locus curved downwardly with the gravity, and the die is disposed to be slightly inclined with respect to a vertical plane such that the axis of the die extends substantially in the tangential direction of the locus at the location of the die.
