Abstract

A method and system are provided for placing nose wires in a facemask production line. A supply of individual pre-cut nose wires are supplied to a dispenser in the production line. With the dispenser, the nose wires are metered at a defined spacing and orientation onto a running carrier web that is conveyed past the dispenser. The carrier web and nose wires deposited thereon are conveyed to a folding station wherein a binder web is folded over an edge of the carrier web such that the nose wires are encapsulated between the binder web and the carrier web.

First claim

1 . A method for placing nose wires in a facemask production line, comprising:
providing a supply of individual pre-cut nose wires to a dispenser in the production line; and with the dispenser, metering the nose wires at a defined spacing and orientation onto a running carrier web that is conveyed past the dispenser; and conveying the carrier web and nose wires deposited thereon to a folding station wherein a binder web is folded over an edge of the carrier web such that the nose wires are encapsulated between the binder web and the carrier web.

2 . The method as in claim 1 , wherein the pre-cut nose wires are supplied in loose, unattached form to a hopper operationally configured with the dispenser.

3 . The method as in claim 1 , wherein the pre-cut nose wires are carried in a cartridge that mates with the dispenser.

4 . The method as in claim 1 , wherein the pre-cut nose wires are supplied in a strip form, and wherein the nose wires are aligned and attached along longitudinal edges in the strip form.

5 . The method as in claim 4 , wherein the dispenser separates a leading nose wire from the strip form for each metering of the nose wires onto the carrier web.

6 . The method as in claim 4 , wherein the nose wires are attached by an adhesive along their longitudinal edges in the strip form.

7 . The method as in claim 1 , wherein the nose wires have an adhesive pre-applied to a surface thereof that contacts the carrier web.

8 . The method as in claim 1 , wherein the carrier web forms an upper panel portion of facemasks produced in the production line.

9 . The method as in claim 1 , further comprising applying an adhesive to the carrier web along an edge that will contain the nose wires prior to placing the nose wires onto the carrier web.

10 . A system for placing precut nose wires in a facemask production line the method of claim 1 .
