Abstract
A method and an apparatus for manufacturing, in a continuous flow, face protection masks including a mask body and two U-shaped elastic thread portions, which are formed by bending respective elastic thread portions retained by a group of sectors including a fixed sector and two movable sectors rotatable with respect to the fixed sector.
Claims4
An apparatus for manufacturing face protection masks having mask bodies, comprising:
- an ear loop forming unit configured to form a first and a second array of ear loops, each including a U-shaped elastic thread,
- an application unit configured to apply and attach pairs of ear loops to respective mask bodies,
- wherein said ear loop forming unit comprises a movable structure carrying two arrays of holding sectors, and wherein said holding sectors are arranged in groups of sectors configured to hold respective elastic threads portions, and
- a cutting roller configured to cut successive portions of elastic threads between each pair of groups of sectors adjacent to each other to form respective discrete elastic thread portions, and
- wherein each of said groups of sectors comprises a fixed sector and two movable sectors disposed laterally on opposite sides of the fixed sector and rotatable with respect to the fixed sector to U-bend the respective elastic discrete thread portions.
