Abstract
A drive chain (38) disclosed is utilized with glass sheet processing equipment (10) to provide frictional driving of conveyor rolls (22) upon rolling movement of the drive chain over an associated support surface (30). Drive chain (38) includes antifriction rollers (40) supported for rolling movement on the support surface (30) and also includes interconnected links (42,44) supported by the antifriction rollers (40) for movement over the support surface in a spaced relationship and having upper surfaces (46) that support and frictionally drive the rolls. Connecting pins (48) interconnect the links and have opposite ends (50) respectively supported by an associated pair of the antifriction rollers (40). Chain links (42,44) are preferably arranged in a side-side relationship in alternating inboard and outboard pairs between the associated pair of antifriction rollers (40). The antifriction drive chain construction reduces friction to eliminate "stick-slip" motion and to also reduce power requirements.
