ABSTRACT:
A conveyor having a plurality of spaced rollers mounted between a pair of elongated horizontal frame members for supporting an article and enabling the article to be conveyed longitudinally of the frame members. The conveyor has a workstation formed by a plurality of interrupter strips extending in the spaces between rollers. Each interrupter strip has a plurality of lifting pads which are selectively movable between a lower position in which the upper surface of the pads are below the tops of the rollers and an upper position in which the upper surface of the pads are above the tops of the rollers for supporting the article and frictionally engaging the article to maintain the article in a stable position above the strips. The interrupter strips also have a plurality of balls mounted for omnidirectional rotation on the interrupter strip. Each ball is selectively moveable between a lower position in which the top of the ball is below the top of the rollers and an upper position in which the top of the ball is above the top of the rollers. The balls are selectively moved independently of the lifting pads so that the article can be supported solely by the balls or by the lifting pads.
