Abstract: The invention relates to a method for checking performance of the cutting-off operation on automatic lathes for working bar material or the like. In accordance with the invention, operating conditions are initiated at the end of a prescribed time interval for the cutting-off operation which result in relative rotation of the spindles in opposite directions in the event that the material has been completely severed at the cutting-off point. A discrepancy between the specified and the actual relative rotation is interpreted as a system failure due to the presence of a material link at the cutting-off point, whereupon a corresponding error signal is triggered.

Abstract: Relatively simple opener assembly structure for maintaining a generally constant vertical relationship between an opener and a trailing press wheel. The structure provides benefits of a parallel linkage design but obviates the extra links of, and provides better trash shedding and tripping characteristics than, a parallel linkage design.
