Abstract

Grading apparatus is provided for use in associating one of a plurality of a grade with each of a plurality of articles travelling in succession along a feed path. The apparatus comprises a grading station of sufficient length to accommodate at least two articles at any one time, a control unit, and at least two means of feeding a grading signal to the control unit. Although the same amount of work is involved it is easier for an operator to grade say four articles at a time over a distance of say 2 feet, rather than to grade one article at a time over a distance of 6 inches.
