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.
