    Abstract: A rotary drilling machine for forming holes of selected size and spacing in continuous strip material such as elastomeric gasket stock used for the manufacture of gaskets for door openings and the like. This machine has a rotary drum unit which carries the strip material along a portion of its peripheral edges. A plurality of drilling units are mounted on this drum unit so as to move with the strip material. The drilling units are oriented toward the peripheral edge, and these drilling units are moved radially in a proper sequence whereby drill bits thereof move toward the strip material to dril the holes and then retract. Tensioning elements produce friction between the strip material and the periphery of the drum unit to accomplish the movement thereof in unison. The tensioning elements, in a preferred form, have signal generating elements whereby the speed of rotation of the drum unit is controlled to prevent sag in the run of the strip material. The radial movement of the drilling units is preferably controlled with a cam and cam follower arrangement. Air for driving driling motors and water for cooling the drill bits is fed to the machine through passageways in the drive shaft for the drum unit. The construction of this machine provides for very accurate drilling of the holes, and a high rate of production with very little maintenance.

    Abstract translation: 一种旋转钻孔机，用于在连续条带材料中形成选定尺寸和间距的孔，例如用于制造用于门开口的垫圈等的弹性垫圈坯料。 该机器具有旋转滚筒单元，其沿着其外围边缘的一部分承载条带材料。 多个钻孔单元安装在该滚筒单元上以便与带状材料一起移动。 钻孔单元朝向外围边缘定向，并且这些钻孔单元以适当的顺序径向移动，从而钻头朝向带材移动以钻出孔然后缩回。 张紧元件在带状材料和鼓单元的周边之间产生摩擦，以一致地实现其移动。 以优选形式的张紧元件具有信号产生元件，由此控制鼓单元的旋转速度以防止带状材料的流动中的松弛。 钻孔单元的径向移动优选地通过凸轮和凸轮从动装置来控制。 用于驱动电动机和用于冷却钻头的水的空气通过用于鼓单元的驱动轴的通道供给到机器。 这种机器的结构提供了非常精确的钻孔，并且生产速度很高，维护保养很少。

    Abstract: A hole drilling method includes a rotating step of attaching a workpiece to a rotary table to make the workpiece rotate in an opposite direction to the rotating direction of the rotary tool and a drilling step of making the rotary tool and the workpiece move relative to each other in a direction in which they approach each other so as to drill a hole. The hole drilling step comprises making a position of the rotary tool track the rotation of the workpiece while drilling the hole so that the rotary tool is arranged at a position for drilling a hole in the workpiece.
