    • A machine for cutting blocks of natural or similar types of stone includes a plurality of diamond-wire loops, wound about an assembly for the support and transmission of the cutting motion to said diamond-wire loops and at least one assembly for supporting, tensioning and guiding the diamond-wire loops; said assemblies move vertically in unison on the structure of the machine; and presents said supporting, tensioning and guiding assembly comprising a set of pulleys for the support and return of each diamond-wire loop, which are mounted and registered, for wire tensioning, on a movable tensioning means whose registration movement is actuated by a tensioning control means, independently of the movable tensioning means of contiguous diamond wires. In its preferred embodiment, the machine also presents an assembly for the support and transmission of the cutting motion to the said diamond-wire loops which includes a wide-diameter wheel about which a belt is wound that is provided with races for housing the diamond-wire loops and which is tensioned by means of a tensioning wheel.
    • 用于切割天然或类似类型石头的块的机器包括多个金刚石线圈,绕组组件缠绕,用于将切割运动支撑并传递到所述金刚石线圈,以及至少一个用于支撑,张紧和 引导金刚石线环; 所述组件在机器的结构上一致地垂直移动; 并且呈现所述支撑,张紧和引导组件,其包括一组皮带轮,用于将用于线张紧的每个金刚石线环的支撑和返回放置在可动张紧装置上,所述可动张紧装置通过张紧控制 独立于相邻金刚石线的可动张紧装置。 在其优选实施例中,机器还提供用于将切割运动的支撑和传递到所述金刚石线环的组件,所述金刚石线环包括宽带轮,围绕所述宽径轮缠绕带,所述宽带轮设有用于容纳金刚石 - 线环,并且通过张紧轮张紧。

    • Saws (1) for cutting or sawing harder materials, such as concrete, concrete structures, brick and stone, have an endless cutting member (4) that is driven through a transmission assembly (11, 20) being supported in the saw and having a drive member and that is guidingly supported on a cutting member supporting portion (3). In such a saw a clamping member is provided that for providing a friction drive contact between the drive member, the clamping member and the cutting member is biased in a direction towards the drive member with driven parts (7) of the cutting member introduced there between, whereby an essentially reduced load on the actual saw, its parts and the cutting member is obtained as well as an improved functionality in the form of an increased flexibility and safety during operation of the saw. The invention also relates to a transmission assembly as well as a cutting member for such a saw.
    • 用于切割或锯切诸如混凝土,混凝土结构,砖和石头的较硬材料的锯(1)具有通过支撑在锯中的传动组件(11,20)驱动的环形切割构件(4),并且具有 驱动构件,其被引导支撑在切割构件支撑部分(3)上。 在这种锯中,提供了夹紧构件,用于在驱动构件之间提供摩擦驱动接触,夹紧构件和切割构件之间沿着朝向驱动构件的方向被偏压,其中在其间引入的切割构件的被驱动部分(7) 从而获得实际锯,其部件和切割构件上的基本上减小的载荷,以及在锯操作期间增加的灵活性和安全性的形式的改进的功能。 本发明还涉及传动组件以及用于这种锯的切割构件。

    • A knife for disk type chip cutter machines with a circular rotatable cutter disk (10) on its first axial side being provided with several knives running from the disk centre to its periphery. An opening (14) is provided in the disk in connection with each knife. The opening (14) has a chip guiding surface to guide separated chips to the other axial cutter disk side. The knife includes a knife carrier, on which the knife Is fixed between a first carrier part (18) provided essentially in line with the first axial cutter disk surface and second carrier part (16) extending downwards in the opening from said cutter disk surface into the cutter disk inside and being a part of the chip guiding device. The knife (12) is on its side facing the other carrier part provided with a chip breaking surface (22) passing the other carrier part (16) into the opening and protecting said carrier part from wear in that the separated chips by means of the chip breaking surface are guided in a direction away from the carrier part.
    • 一种具有圆形可旋转切割盘(10)的圆盘式切割机的刀在其第一轴向侧上设置有从盘中心延伸到其周边的若干刀。 一个开口(14)设置在盘中,与每个刀相连。 开口(14)具有芯片引导表面,以将分离的芯片引导到另一个轴向切割器盘侧。 刀包括刀架,刀固定在基本上与第一轴向刀盘盘表面成直线的第一承载部件(18)和从刀盘盘表面向开口处向下延伸的第二托架部分(16)之间固定 刀盘内部并且是芯片引导装置的一部分。 刀具(12)位于其另一个托架部分的一侧,该托架部分具有通过另一托架部分(16)进入开口的破碎表面(22),并且保护所述载体部件免受磨损,从而使分离的碎片借助于 切屑断面在远离载体部分的方向被引导。
