ABSTRACT:
Prior to the forming of bar material, without creating internal stresses, on transverse transport presses, bars are sub-divided into sections of equal volume, the end-pieces of each bar having to be discarded before further processing. To provide for the automatic and material-saving discarding of the end pieces, two light barriers are installed in the feed zone of the bars, the distance (a) between these light barriers being newly stored in a microprocessor as each bar is fed in, and this distance being converted, by calculation, to three further distances (b, c, d). By reference to these data, the microprocessor controls the discarding operation, with one, or at the most two, section lengths being discarded per bar, according to whether the interface between two successive bars is located in the central region of the section length in question, or in one of its two end-regions.
