When sewing stretch binding the unit is adjusted to move the folder in snychronization with the feed dog. The distance of movement should be greater than the stitch length. This movement allows the binder to draw additional material from the roll and feed fullness under the foot. This relieves the tension created by the binding turning the 90 degree corner, and reduces the pucker and waving resulting from that tension.
