Abstract

A facer for use in preparing the opposed ends of polyolefin pipes for fusion into a pipeline has a pair of cutting wheels which rotate in unison. A controller causes the cutting wheels to trace and face the pipe end walls in a closed loop path.

Claims (2)

1. For preparing opposed ends of polyolefin pipes for fusion into a pipeline, a facer comprising a pair of spaced-apart parallel vertically oriented cutting wheels on opposite sides of a boom and rotatable in unison about a common axis extending through a free end of said boom and a motor driving said pair of cutting wheels about said common axis, said boom being configured to enable said common axis to trace a thickness of the opposed ends of the polyolefin pipes in a closed-loop path whereby said pair of parallel cutting wheels will simultaneously face the opposed ends of the polyolefin pipes.

2. For preparing opposed ends of polyolefin pipes for fusion into a pipeline, a facer comprising a pair of spaced-apart parallel vertically oriented cutting wheels on opposite sides of a boom and rotatable in unison about a common axis extending through a free end of said boom and a motor driving said pair of cutting wheels about said common axis, a length and a width of said boom and a distance between said pair of parallel cutting wheels being coordinated to enable said common axis to trace a thickness of the opposed ends of the polyolefin pipes in a closed-loop path whereby said pair of parallel cutting wheels will simultaneously face the opposed ends of the polyolefin pipes.
