摘要：
Systems are provided for fabricating a plurality of possible pleat packs used in the formation of circumferentially pleated filter sleeves comprising a substantially horizontal contact surface, a pleating machine having cutting structure, operatively positioned proximate the substantially horizontal contact plane, for delivering continuous upstanding pleat packs of a predetermined pleat formation to the horizontal contact surface, structure for guiding the upstanding pleat packs received from the pleating machine into a flattened condition, structure for securing the pleat packs in the flattened condition and structure for forming the flattened pleat packs into a predetermined length for subsequent formation into sleeves of circumferential pleats. Methods for fabricating a plurality of possible pleat packs used in the formation of circumferentially pleated filter sleeves are also provided.
