Abstract
Abstract Tools mounted on swinging arms are fixed to a rotating head which, in turn, is carried by a front casing. A rear casing is coupled to the front casing and forms a chassis through parallel longitudinal members which are fixed to the front casing and are slidably received by the rear casing permitting relative longitudinal movement between the front and rear casings. A guide carriage is slidably coupled to the ends of the parallel members which protrude rearwardly of the rear casing. The head is selectively rotated and the arms carrying the tools are oscillated by a drive mechanism carried by the rear casing. Bearing jacks carried by the guide carriage selectively fixes the carriage at a given longitudinal position, while pushing jacks carried by the carriage and acting on the front casing advances the front casing when the carriage is longitudinally stopped in fixed position by the bearing jacks.
