ABSTRACT:
A combination of an apparatus or an extrusion for lengthwise movement of the elongate metal extrusion. The extrusion having therein a lengthwise cavity which has a central portion and two pockets disposed on opposite sides of and opening into the central portion. The apparatus has a tool disposed in the cavity and supported for eccentric rotation about an axis extending perpendicular to the direction of movement of the extrusion, the tool having abrading points which are spaced angularly about its centerline and which engage and physically roughen a surface in one of the pockets. The degree of eccentricity is adjustable. In a variation, the apparatus effects movement of a first member having two pegs which engage angled slots in a second member supporting a tool in the extrusion cavity, the tool being moved rectilinearly into and out of engagement with the extrusion surface in a manner physically roughening the surface.
