Abstract: A line accumulation conveyor includes a secondary belt rotatably mounted to a frame so as to define upper and lower surfaces caused to move in opposite directions by rotation of the secondary belt. The conveyor further includes a product conveying belt that is rotatably engaged with the secondary belt at a first position on the first surface and at a second position on the second surface therebetween in an endless manner. The product conveying belt has an upper portion that extends from the first surface in an upper plane between the first position and a looping portion of the product conveying belt and a lower portion that extends from the second surface in a lower plane between the looping portion and the second position. The upper portion of the product conveying belt defines a product accumulation path that can be elongate or shorten by rotating the secondary belt.
