Abstract:
A multiple tool device, particularly adapted to prepare tubular elements to be welded by electrofusion, comprising a cup member which is associable with the end portion of a tubular element and is provided with motion transmission means adapted to turn the multiple tool device. The particularity of the present invention resides in that it comprises scraper means adapted to remove the outer surface layer of the end portion and facing means which have a working motion that is opposite with respect to the preceding means and are adapted to face the edge of the end portion so as to make it perpendicular to the axis of the tubular element.
