ABSTRACT:
A merge conveyor comprising a timing conveyor feeding a singulating conveyor characterized by a transverse-roller conveyor belt having rollers with a high-friction peripheral surface. The timing conveyor delivers articles to the singulating conveyor one article at a time at precise intervals. The rollers in the transverse-roller belt rotate freely transverse to the conveying direction. A plow guides the timed articles received on the singulating belt into a single file. The high-friction rollers inhibit the rollers from sliding along the rollers in the conveying direction to maintain the precise timing established by the timing conveyor.
