Abstract
A portable apparatus including a four-legged support that is equipped with adjustable support bases. The apparatus also includes a centering mechanism that includes rotatable eccentric discs, and a modified rotating unit, the rotating arm of which is provided with an adjustment mechanism that is equipped with a sensing device, and with a tracing device that is equipped with various copying templates and is coupled with a machining or processing tool for machining the rim of a flanged, flat, dished semi-ellipsoidal head in preparation for a welding seam connection with a tubular member to produce a circular cylindrical reaction vessel. The apparatus is installed in the upwardly open head coaxial to the axis of the latter. During each rotation of the rotating arm, the machining tool experiences a feed movement and an adjustment movement that is corrected for the geometry of the workpiece or head.
