ABSTRACT:
An apparatus for preparing the welding region on the outer surface of plastic pipes, comprising elements for anchoring to a pipe; a threaded pivot being coupled to the anchoring elements to perform a longitudinal, rotary and translational motion; supporting elements for a tool being jointly coupled to the threaded pivot, that can be arranged so as to interfere with, and remove material from, the outer surface of the pipe. The anchoring elements comprise a central body with longitudinal sliding guides thereon for rod-like elements, which protrude partially from the central body, do not intersect each other, and support at ends feet for resting against the inner surface of the pipe. Respective racks are provided longitudinally on the rod-like elements and are kinematically connected to a common actuation gear system.
