ABSTRACT:
A flagging apparatus having non-contacting proximity switches emitting a directional energy field and producing a signal in response to an induced alteration of the energy field, a rotatable target element having target faces for engaging and altering the energy field and a probe attached to the target element and contacted by a surface of a workpiece is provided for repetitively positioning workpieces in the work space of a grinder in reference to a grinding wheel. Advantageously, the flagging apparatus is operative in either of two opposing directions without a mechanical and/or electrical change over or modification in the apparatus with a change in operating direction. To achieve the operation in either of two opposing directions the target faces of the target element are spaced apart from each other such that the sequence in which the energy fields are engaged and altered by the target faces remains independent of the direction of rotation of the target element.
