摘要： An electro-mechanical machine for fusing small diameter polyolefin pipe includes a carriage and controls. The carriage has fixed and travelling jaws that grip a pipeline and a pipe stick and electrically driven screws that bring the jaws into and out of close proximity for performance of fusion process tasks. The controls include an electrical closed loop circuit that controls operation of the screws to transfer the travelling jaws to a base axial distance from the fixed jaws and an electrical load cell feedback circuit that controls operation of the screws to reciprocate the travelling jaws in relation to the base axial distance in response to feedback from the load cells so as to maintain a predetermined force between the pipes.

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.
