    摘要： One fusion machine can butt or socket fuse polyolefin pipes and fittings in straight alignment or at inwardly or outwardly mitered universal angles from 0° to 45° for butt fusion and from 0° to 10° for socket fusion. The machine is manually driven, hydraulically monitored and operated in all configurations from one side of the machine.

    摘要： A fusion machine (10) which can be top-loaded on very large polyolefin pipes and pipelines has jaws which consist of an upper half jaw (63/163) and lower left and right (65/165) complemental jaws which pivot on the half jaw. Left and right actuators (110) connected between the complemental jaws and the half jaw (61) operate in one direction to cause the complemental jaws to rotate to an opened condition in which the upper half jaw (61) can be lowered onto and lifted from the pipes to be fused and in the other direction to cause the complemental jaws to rotate to a closed condition in which the pipes to be fused are gripped so substantially around their circumferences as to resist their deformation from round during manipulation by the machine (10). The top-loading machine minimizes the need for heavy equipment to load and unload pipe to and from the fusion machine (10).

    摘要： A facer (F) facing the ends of polyolefin pipes for butt fusion is modular in the sense that it employs three types of modules, a drive unit (10), two blade holders (60) and a motor assembly (80), that are separable from one another and each independently light enough to be hand-lifted along walls and up to ceilings. The drive unit (10) module is adjustable to accommodate different guide rail (R) spacings. The blade holder (60) modules are interchangeable to accommodate different diameters of pipe. The motor assembly (80) module has multispeed capability to accommodate the total area of material to be faced. Each module can be exchanged or modified without use of tools to change the geometry of the assembled facer to accommodate different fusion machines and/or diameters of pipe within working spaces dictated by the diameter of the pipe and not by a fixed geometry of a facer.
