    • A strip (56) of non-metallic material and one (59) of a metallic material are wrapped simultaneously about an advancing cable core (32) to enclose partially the core. Then longitudinal edge portions (71, 72) of the strip of non-metallic material are separated by a shoe (150) which permits movement of the edge portions in a direction circumferentially of the core. One longitudinal edge portion (72) of the non-metallic strip becomes confined in a guideway (118) of a tool (99) and longitudinal edge portions (73, 74) of the metallic strip (59) are guided along guideways (117, 118) of the tool as the strips are moved through a converging passageway (103). This controls the relative circumferential movement between the edge portions as the strips are moved through the passageway to form a core wrap (33) and a shield (34). As a result, the longitudinal edge portions of the non-metallic and metallic strips are caused to form seams which are aligned radially of the core and which are overlapped in opposite circumferential directions. This arrangement obviates the necessity for binding the core wrap prior to the forming of the shield.
    • 非金属材料的条带(56)和金属材料(59)的一部分同时围绕前进的电缆芯(32)包裹以部分地包围芯。 然后,非金属材料带的纵向边缘部分(71,72)由允许边缘部分在芯部的圆周方向上移动的靴子(150)分开。 非金属条的一个纵向边缘部分(72)被限制在工具(99)的导轨(118)中,并且金属条(59)的纵向边缘部分(73,74)沿着导轨(117, 当条带移动通过会聚通道(103)时,该工具的工具(118)。 当带移动通过通道以形成芯包裹物(33)和屏蔽(34)时,这控制边缘部分之间的相对周向运动。 结果,非金属和金属带的纵向边缘部分形成接缝,这些接缝与芯的径向对准并且在相反的圆周方向上重叠。 这种布置避免了在形成屏蔽之前结合芯包裹的必要性。

    • A machine for applying tubing over any desired area of an object, including a supply of flat, flexible tubing having sharp creases on either side of the tubing, apparatus for reducing slightly the creases to open partially the tubing, a knife for cutting the partially opened tubing to provide a predetermined length of cut tubing, a mechanism to hold externally at the reduced creases the tubing which is being cut and to shape the cut tubing into any desired shape corresponding to the shape of the object which is to receive the cut tubing, and apparatus for moving the cut and shaped tubing around the object. In one embodiment, the holding and shaping mechanism is moved together with the cut tubing over the object, the mechanism then releasing the cut tubing around the object and returning to an initial position to hold and shape additional cut tubing. In another embodiment, the mechanism is held away from the object, but the cut tubing is caused to slide out of the mechanism and over the object. Two embodiments for feeding the flexible tubing in relation to the cutting knife are also disclosed, one embodiment including a shaft encoder-decoder and photoscanner technique which is used with tubing having printed matter, and the other embodiment including only the shaft encoder-decoder technique which is used with plain tubing.
    • 一种用于在物体的任何所需区域上施加管道的机器,包括在管道的任一侧上提供具有锋利褶皱的扁平柔性管道的装置,用于稍微减小折痕以部分地打开管道的装置,用于切割部分打开的刀 管道以提供预定长度的切割管道,用于在外部保持在被切割的管道的减少的机构并且将切割管线成形为对应于待接收切割管道的物体的形状的任何期望的形状, 以及用于使切割和成形管围绕物体移动的装置。 在一个实施例中,保持和成形机构与切割的管道一起移动到物体上,然后机构将切割的管道释放到物体周围并返回到初始位置以保持和形成另外的切割管道。 在另一个实施例中,机构被保持远离物体,但是切割的管道被引导出机构并在物体上方。 还公开了用于相对于切割刀进给柔性管的两个实施例,一个实施例包括与具有印刷物的管一起使用的轴编码器 - 解码器和照相扫描仪技术,另一个实施例仅包括轴编码器 - 解码器技术, 与普通管道一起使用。

    • An apparatus for transporting and wrapping pipe insulation comprising a frame and a pair of arms mounted on the frame for swinging movement about a longitudinal axis. A row of longitudinally spaced vacuum pads is suspended and on each arm a pair of transversly spaced rows of longitudinally spaced vacuum pads are suspended on the arms inwardly of the first-mentioned rows on said arms. Vacuum can be selectively supplied to the rows of vacuum pads. Means are provided for swinging the arms toward and away from one another whereby when the arms are extended and the vacuum pads are brought into engagement with a generally flat piece of insulation, the insulation is engaged and may be lifted and transported by manipulating the frame to bring the insulation adjacent a length of pipe and the arms may thereafter be swung inwardly to wrap the insulation about the length of pipe. Provision is made for rotating the insulation relative to the pipe to make the ends of the insulation panel more readily avaiable to form a seam.
