Apparatus and method for manufacturing masks

An apparatus for manufacturing trapezoid-shaped masks, each mask comprising an opening along a wide base of the trapezoid and a continuous joint along two sides and a narrow base of the trapezoid, the apparatus comprising:

• a first feeding unit, for providing three or more rolled fabrics;
• a second feeding unit, for providing one or more rolled materials, simultaneously to the providing the three or more rolled fabrics;
• a first folding and joining unit, for folding and joining together edges of three or more fabrics provided by the first feeding unit to form a joint multilayered fabric;
• a second folding and joining unit, for folding and joining the edges of one or more materials provided by the second feeding unit to form folded material;
• and
• a joining unit configured to join together the joint multilayered fabric and the folded material, by forming the continuous joint, thereby forming at least two adjacent masks in relatively alternating positions, such that the open side of one mask is pointing in an opposite direction from the open side of the adjacent mask.
