<p>The system turns components such as profiled metal frame sections, resting on one face or on two edges, to allow drilling and welding operations to be carried out. While the component (15) is resting on a support (15), it is gripped above one of the edges of its supporting surface by a jaw etc. (38), and tilted about this edge by application of coaxial torque, without sliding it sideways. The jaw can be turned about its axis, while at the same time this axis pivots about a fixed point, so as to follow a conical trajectory.</p> |
