ABSTRACT:
A device for guiding objects such as printed circuit boards has a cooperating pair of spaced apart endless chain conveyors with leaf-like spring members connected to the links of each conveyor by holders such that free ends of leaf-like spring members of opposed conveyors are adapted to engage opposite edges of the object in order to grip the object for transporting by the conveyors. The end of each leaf-like spring member which is attached to a conveyor is provided with a reaction arm portion, angularly disposed relative to the free end thereof at a transition portion, and each holder has a recessed portion into which a reaction arm is form fitted and engaged by a retaining member so that the leaf-like spring member is tiltable about a front edge of the recessed portion of the holder generally at the transition portion of the leaf-like spring member.
