    • A retractable cutter for cutting an indefinite length strand of suture material to a definite length while the strand is suspended under tension along a first axis, comprises a cutting blade mounted for at least reciprocal movement transverse to the first axis, from a first retracted position to a second cutting position. A support block is actuated to position the indefinite length strand for cutting thereof, and to support the strand as the cutting blade traverses the first axis as it reciprocates from the retracted position to the cutting position. The cutting blade is angled with respect to its reciprocating motion to effect a slice ratio of at least 1:1 as the blade cuts the supported suture strand at the cutting position to obtain a clean, broom-free cut.
    • 一种可缩回切割器,用于在股线沿着第一轴线的张力下悬挂时,将不定长度的缝合材料股线切割成一定的长度,包括一个切割刀片,其安装成至少相对于第一轴线的往复运动,从第一缩回位置到 第二切割位置。 驱动支撑块以定位用于切割的不确定长度的线,并且当刀片在从缩回位置向切割位置往复运动时横切第一轴线时支撑线。 当刀片在切割位置切割支撑的缝合线时,切割刀片相对于其往复运动是成角度的,从而达到至少1:1的切片比,以获得清洁,无扫帚切割。

    • In an apparatus for spreading and cutting layups of sheet material pin mechanisms (72) are distributed over the supporting surface of the table (12) and include pins (74) moveable between raised and lowered positions to enable selected portions of the supporting surface to be adapted, or not, to a spreading procedure involving the pinning of each layer as it is spread. The supporting surface (20̸) is divided into sections (70̸) and the pin mechanisms (72) of each section are operated in unison by a control element (114) located on the side wall of the table with each control element (114) being aligned with its associated section (70̸) of the table so as to be quickly and easily operable by an operator without the operator having to give great thought or attention to which pin mechanisms (72) are operated by which switch. The pins (74) passing through a layup being cut by the cutter (24) are automatically lowered upon the cutter (24) approaching the pins to avoid collision between the pins and the cutter. This latter function can be defeated, if desired, to allow the cutter (24) to be passed over a layup in a noncutting mode without pins (74) being withdrawn from the layup.

    • The vertically reciprocal upper blade assembly of a sheet metal squaring shear is activated in a substantially vertical path past a fixed lower blade (16) by means of one or more reciprocal rotary hydraulic actuators (19). The output drive shaft (18) of the hydraulic actuator(s) (19) is connected to one or more drive straps (26) by an eccentric cam (30) which is keyed to the drive shaft (18) and rotatably received within the straps (26). The horizontal gap between the upper blade (25) and the lower blade (16) is precisely controlled by suspending the blade supporting gib bracket (20) from pins (50-52) on the side walls (10-12) of the apparatus housing and adjustably connecting the gib plate to the pins by eccentric cams (58). The gib mounting system also provides for adjusting the angle of the upper blade (25) with respect to the lower blade (16). An improved hold down assembly limits the stroke of the hold down pins (116) to maintain a slight clearance (z) between the hold down pins (116) and the bed surface (14) at all times. A unique hydraulic actuator mounting bracket (150) facilitates alignment of the actuator (19) with the drive shaft (18) by permitting adjustment of the actuator (19) relative to the shaft (18) after the shaft (18) is properly mounted and aligned in the machine frame (10).
    • 通过一个或多个往复式旋转液压致动器(19),通过固定的下叶片(16)的基本上垂直的路径激活钣金平切剪的垂直往复上刀片组件。 液压致动器(19)的输出驱动轴(18)通过偏心凸轮(30)连接到一个或多个驱动带(26),所述偏心凸轮(30)键合到驱动轴(18)并可旋转地接收在驱动轴 皮带(26)。 上刀片(25)和下刀片(16)之间的水平间隙通过将刀片支撑臂架(20)从销(50-52)悬挂在设备壳体的侧壁(10-12)上而被精确地控制 并且通过偏心凸轮(58)可调节地将前桥板连接到销上。 前桥安装系统还提供了调节上刀片(25)相对于下刀片(16)的角度。 改进的压紧组件限制了压紧销(116)的行程,以始终保持压紧销(116)和床表面(14)之间的微小间隙(z)。 独特的液压致动器安装支架(150)通过在轴(18)被正确安装之后允许致动器(19)相对于轴(18)调节,便于致动器(19)与驱动轴(18)对准, 在机架(10)中对齐。
