Abstract
An automated system and method wrap the fastening ties around the body of a continuous stream of facemasks in a facemask production line. The facemasks are oriented such that each facemask has a leading pair of ties and a trailing pair of ties extending from a body in a conveying direction of the production line. The leading pair of ties is drawn below the body as the facemask continues to be conveyed in the conveying. The body is conveyed through a plurality of conveyor sections oriented at angles such that the conveying direction of the body changes at a junction from one conveyor section to an adjacent conveyor section. At the junctions between conveyor sections, an impinging force is directed against the body that causes the body to flip, thereby causing the leading and trailing pairs of ties to further wrap around the body.
