    • A biscuit cutter (20, 130) is provided for cutting an arcuate slot in the edge surface (26, 138) of a workpiece (22, 134). The biscuit cutter (20, 130) is made of a base (32, 142), a drive motor (30, 194), a rotary cutter blade (96, 192), and an adjustable fence (38, 148). The base (32, 142) is provided by the first planar surface (34, 144) having an elongated opening (36, 146) through which the rotary cutting blade (96, 192) is positionable in a plurality of extended positions corresponding to a selected one of a plurality of predetermined sized biscuits. The adjustable fence (38, 148) has a second fence surface (40, 150) for engaging the workpiece (22, 134) and has a centerline indicia (86, 174) and a plurality of slot length indicia (90, 90', 92, 92', 94, 94', 176, 176', 178, 178', 180, 180') spaced about the centerline indicia (86, 174) for providing a visual indication to the user of the length of the slot to be formed in the workpiece (22, 134) for each of the plurality of biscuit sizes.
    • 提供了用于切割工件(22,134)的边缘表面(26,138)中的弓形狭槽的饼干切割器(20,130)。 饼干切割器(20,130)由基座(32,142),驱动马达(30,194),旋转切割刀片(96,192)和可调整的围栏(38,148)制成。 基部(32,142)由具有细长开口(36,146)的第一平坦表面(34,144)提供,旋转切割刀片(96,192)可通过该细长开口定位在对应于多个延伸位置的多个延伸位置 选择多个预定尺寸的饼干中的一个。 可调节围栏(38,148)具有用于接合工件(22,134)的第二栅栏表面(40,150),并具有中心线标记(86,174)和多个槽长度标记(90,90'), 围绕中心线标记(86,174)间隔开的92,92',94,94',176,176',178,178',180,180'),用于向用户提供视觉指示槽长度的视觉指示 在多个饼干尺寸中的每一个上形成在工件(22,134)中。

    • The invention relates to a cutting-off apparatus, especially a circular saw, comprising two parallel circular disc-shaped, coaxially contra-rotating cutting-off elements (1, 2), especially circular saw blades, and a protective hood (3). In order to improve manual guidance and accident-free operation and positioning, the protective hood (3) can be moved in relation to the cutting-off elements (1, 2) and is loaded by a spring (4). The protective hood covers at least totally the cutting-off elements (1, 2) when it is placed in an inoperative position. When the protective hood (3) is supported on a workpiece that is to be cut-off or on a working surface, the cutting-off elements (1, 2) are moved (A, B, C) by the tension of the spring (4) into working position, in which the cutting-off elements (1, 2) partially come out from the protective hood (3) through an outlet (6).
    • 本发明涉及一种分离装置,特别是圆锯具有两个圆盘形的,平行的,同轴反向旋转驱动的分离元件(1,2),特别是圆锯片,带有防护罩(3)。 为了通过一个弹簧来改善手引导的和偶然的安全处理和存储,保护罩(3)的分离元件(1,2)可相对于和偏置(4)和在静止位置,所述分离元件(1,2)至少完全的存在覆盖 从,在支撑保护罩的是(3)抵靠待分离工件或工作表面,所述分离元件(1,2)抵抗弹簧(4)在工作位置移动(A,B,C),的力,其中所述分隔元件( 1,2)部分地从保护罩(3)(通过出口开口6)突出。
