A method of measuring a length of sections of extrados or intrados curves of an elongated workpiece travelling in a bending machine along a forwarding direction, the elongated workpiece having cross-sections each of which is separated by a neutral axis in both an extended portion and a compressed portion when the elongated workpiece is subjected to bending, and at least a neutral cross-section, i.e. not subjected to bending, neutral cross-section beyond which the bending of the elongated workpiece begins along the forwarding direction thereof, provides a measuring instrument positioned so that it engages either an extrados or an intrados point of the elongated workpiece near the neutral cross-section, but displaced therefrom in the forwarding direction of the elongated workpiece. Further, a measuring instrument on a bending machine that embodies the method is described.
A method of measuring a length of sections of extrados or intrados curves of an elongated workpiece travelling in a bending machine along a forwarding direction, the elongated workpiece having cross-sections each of which is separated by a neutral axis in both an extended portion and a compressed portion when the elongated workpiece is subjected to bending, and at least a neutral cross-section, i.e. not subjected to bending, neutral cross-section beyond which the bending of the elongated workpiece begins along the forwarding direction thereof, characterised in that the length measuring is performed by a relevant instrument positioned so that, in measuring, it engages either an extrados or an intrados point of the elongated workpiece near the neutral cross-section, but displaced therefrom in the forwarding direction of the elongated workpiece.
A length measuring instrument for measuring sections of extrados or intrados curves of an elongated workpiece travelling in a symmetrical pyramidal roller bending machine having a movable upper deforming roller and at least a pair of lower input and output driving rollers along the forwarding direction of the elongated workpiece, a central axis of symmetry of the bending machine being a trace of a neutral cross-section, i.e. not subjected to bending, characterised in that the length measuring instrument is positioned so that, in measuring, it engages either an extrados or an intrados point of the elongated workpiece beyond the axis of symmetry of the bending machine toward the lower output driving roller.
