ABSTRACT:
A hem folding attachment (23) or former having a support plate (26), an underlay plate (29), a set of air nozzles (32) or air jets, and a vacuum chamber (35) having a reduced pressure area defined therein. The support plate (26) or tongue is adjustably mounted above the vacuum chamber (35) and the front edge (38) of the support plate (26) extends beyond and overhangs the edge of the vacuum chamber (35). An edge of a piece of material is folded around the front edge (38) of the support plate (26) and extends back toward the vacuum chamber (35). The vacuum chamber has a guiding surface (41) with a set of air intake orifices (47) defined therein for aligning the edge of the material. The orifices (47) receive air from a set of nozzles (32). The nozzles (32) and the vacuum chamber (35) assist the raw edge of the piece of material in being folded back underneath the rest of the material. An underlay plate (29) also guides the edge of the material toward the vacuum chamber (35).
