    摘要： A cutter for use in making plugs of wood or the like to be used in the insulation industry for plugging holes made in order to provide insulation in an existing structure. The cutter is adapted to be held in a chuck or the like for rotation about a central axis defined by a holder, with a pilot being spring biased in the holder and having a centering tit for locating the wooden plug as it is being cut. Four steel cutters are provided in circumaxially spaced relationship around the axis, and two of these are oriented at a slightly different angle than the other two such that the plug can be cut with two distinct tapers, such that the steeper plug taper permits the plug to be first located in the hole to be plugged, and a shallower slightly larger diameter tapered portion for securing the plug in the hole. Each cutter is adjustable in the holder, and is held in place by a screw with any number of shims being provided in order to cut plugs of different size.

    摘要翻译： 用于制造用于绝缘工业中用于堵塞孔的木材或类似物的切割器，以便在现有结构中提供绝缘。 切割器适于被保持在卡盘等中以围绕由保持器限定的中心轴线旋转，其中引导件被弹簧偏置在保持器中并且具有用于在被切割时定位木塞的定中心。 四个钢切割器围绕轴线以周向间隔的关系设置，并且其中两个被切割成与其他两个角度稍微不同的角度，使得插头可以用两个明显的锥形切割，使得更陡的塞子锥形允许塞子 首先位于待堵塞的孔中，并且具有较浅的较大直径的锥形部分，用于将插头固定在孔中。 每个切割器在保持器中是可调节的，并且通过具有任何数量的垫片的螺钉保持就位，以便切割不同尺寸的塞子。
