Abstract
A textile fold control system (40) includes a hem engager (46) mounted to a downstream side of a sewing machine (42), and a roller (76) for engaging and moving a hem formed in a textile work piece slightly downward so as to bend the hem about a trailing edge (79) of a work surface (54) of the sewing machine, thereby applying increased frictional contact between an edge portion (88) of the work piece and the work surface, and additional surface-to-surface contact between the edge portion and an adjacent body portion (90) of the hem in order to avoid the curling or unfolding of the hem during a pre-feed portion of the sewing cycle of the sewing machine.
