Abstract:
In apparatus for grinding one or more profiles in a length of an elongated article by advancing said article axially through a gap formed between continuously rotating work and regulating wheels during a grinding cycle in which said gap is adjustable according to the diameter to which said article is to be ground, the improvement comprising:signal-responsive means for incrementally adjusting said gap in a radial direction relative to axial advancement of said article through said gap;image detecting means upstream of said wheels through which said article is advanced including a series of image detectors for generating a succession of input signals in response to advancement of a trailing end of said article thereacross; andgap control means for generating and transmitting a plurality of output signals to said signal-responsive means wherein each of said output signals is generated in response to receiving a predetermined number of input signals from said image detecting means independently of the rate of axial advancement of said article.
