ABSTRACT:
A method for automatically controlling the operation of a rod-working apparatus of the type including a rod-feeding unit which feeds towards a cyclically operating work tool a certain length of rod per work cycle of the tool. There are selected a minimum and a maximum distance through which a rod to be fed towards the work tool is to be permitted to advance per work cycle of the tool. A rod is fed towards and into the range of operation of the tool. The actual distance advanced by the rod during a work cycle of the tool is determined. It is also determined whether the actual distance of advancement falls within the range defined between the preselected minimum and maximum distances. When the actual distance falls outside such range, operation of the rod-feeding unit is terminated.
