    • A method of producing a plurality of face masks is provided. The method includes the step of providing a continuous web that is of the same material throughout. A plurality of body portions are stamped from the continuous web so that each of the plurality of face masks has one body portion. A plurality of left extension portions are stamped from the continuous web so that each of the body portions has one left extension portion integrally attached thereto. A plurality of right extension portions are stamped from the continuous web so that each of the body portions has one right extension portion integrally attached thereto. A dispenser assembly for dispensing face masks is also provided. The assembly includes a core and a roll of face masks that are rotatably disposed on the core. As least one of the face masks includes a body portion and left extension portion that is integrally attached to the body portion. A right extension portion is integrally attached to the body portion.
    • 提供了一种制造多个面罩的方法。 该方法包括提供整个相同材料的连续卷材的步骤。 多个主体部分从连续卷材冲压成多个面罩中的每一个具有一个主体部分。 多个左延伸部分从连续腹板上冲压,使得每个主体部分具有一体地附接到其上的一个左延伸部分。 多个右延伸部分从连续腹板上冲压,使得每个主体部分具有与其一体地附接的一个右延伸部分。 还提供了用于分配面罩的分配器组件。 组件包括可旋转地设置在芯上的芯和一卷面罩。 至少一个面罩包括主体部分和一体地附接到主体部分的左延伸部分。 一个右延伸部分整体连接到主体部分。
