ABSTRACT:
A pipe scraper for scraping the end of a plastics pipe such as a plastics gas main or water main has a framework (10) in which is journaled a helically bladed rotary cutter (14) driven by means of a lever (17). On the shaft carrying the cutter is a pinion (16) which meshes with a larger pinion (19) driving a friction surface roller (21). The cutter is held in a Reed clamp and as the lever (17) is turned it rotates the helically bladed rotary cutter so as to scrape a low angle helical scrape approximating a longitudinal scrape. At the same time the rotation of the roller (21) causes the whole framework to rotate around the surface of the pipe so as to scrape the whole end peripheral surface.
