发明名称 Method for manufacturing a facemask structure
摘要 A method for manufacturing facemask structure includes following steps. A facemask with first folds is placed on a seat and a pressing body forces the facemask so as to form step-shaped structures. Then, two movable plates are used to form the step-shaped structures as second folds on the facemask. Thereby, the mask can be stretched both vertically and horizontally, in a way that the mask body becomes more three-dimensional, fitting more firmly to the contours of a wearer's face, and providing more comfort and convenience than the conventional facemasks.
