Abstract: A web folding apparatus including two pairs of creasing plates, a creasing bar or element, and cooperative mechanism causing the crease bar to move toward the plates to form a crease in a piece of sheet material, and causing the hinged pairs of plates to swing toward each other as the crease bar moves away, to fold the creased sheet material about a fold line substantially perpendicular to the crease line.The apparatus is particularly useful in folding the ends of flexible webbing preparatory to being grommeted, as for example in lawn furniture.
