Abstract
A device for the automatic control of the feed of a tubular wire, made of precious or non-precious material, in goldsmith industry machine tools, that allows to maintain a predetermined orientation of the continuous longitudinal groove present on the wire itself. The device comprises the use of sensing means, in particular of the optical kind, for following the groove and its displacements within a predetermined operative band. Means are moreover provided for the rotation of the wire around its axis that are driven by said sensing means: when the groove goes out of said operative band, the wire is automatically rotated in one or the other sense up to bring back the groove within said band. This control is presently made upon sight by the operator.
