ABSTRACT:
A conveyance arrangement for conveying planar circuit boards is characterized by a roller drive in which the individual rollers have an angled driving surface formed thereon. The angularity of the driving surface is selected such that when the surface engages the edge thickness of a circuit board the board, if otherwise unrestrained, is displaced at a predetermined rectilinear velocity. However, if the board is restrained, the driving surface slips with respect to the edge of the board.
