Abstract

A method and associated system are provided for cutting and placing individual nose wires in a facemask production line. A continuous wire is supplied from a supply source to a cutting station in the facemask production line where the continuous wire is cut into individual nose wires having a defined length. A first web is conveyed to a vacuum conveyor, and the individual nose wires are deposited from the cutting station onto the vacuum conveyor such that the nose wires are drawn by vacuum against the first web at a defined spacing and orientation. With the vacuum conveyor, the first web and attached nose wires are conveyed to a folding station wherein the first web and nose wires are combined with a second web such that the nose wires are encapsulated between the first and second webs.

First claim

What is claimed is:

1. A method for cutting and placing individual nose wires in a facemask production line, comprising:
supplying a continuous wire from a supply source to a cutting station in the facemask production line;
at the cutting station, cutting the continuous wire into individual nose wires having a defined length;
conveying a binder web to a vacuum conveyor;
conveying the individual nose wires from the cutting station to the vacuum conveyor such that the nose wires are drawn by vacuum against the binder web at a defined spacing; and

with the vacuum conveyor, moving the binder web and attached nose wires to a folding station wherein the binder web with attached nose wires are folded over an edge of a carrier web such that the nose wires are encapsulated between the binder web and the carrier web.

2. The method as in claim 1 , further comprising conveying the carrier web with attached binder web and nose wires to a bonding station where the binder web is bonded to the carrier web.

3. The method as in claim 1 , wherein the vacuum conveyor is a rotary wheel conveyor that draws the nose wires radially inward against the binder web as the rotary wheel conveyor rotates.

4. The method as in claim 1 , wherein the vacuum conveyor is a linear web conveyor that draws the nose wires against the binder web.

5. A system for cutting and placing individual nose wires in a facemask production line, wherein the system is specifically configured for practice of the method of claim 1 .

6. A method for cutting and placing individual nose wires in a facemask production line, comprising:
supplying a continuous wire from a supply source to a cutting station in the facemask production line;
at the cutting station, cutting the continuous wire into individual nose wires having a defined length;
conveying a first web to a vacuum conveyor;
conveying the individual nose wires from the cutting station to the vacuum conveyor such that the nose wires are drawn by vacuum against the first web at a defined spacing; and

with the vacuum conveyor, moving the first web and attached nose wires to a folding station wherein the first web with attached nose wires are combined with a second web such that the nose wires are encapsulated between the webs.

7. The method as in claim 6 , further comprising conveying the webs and encapsulated nose wires to a bonding station where the webs are bonded together.

8. The method as in claim 6 , wherein the vacuum conveyor is a rotary wheel conveyor that draws the nose wires radially inward against the first web as the rotary wheel conveyor rotates.

9. The method as in claim 6 , wherein the vacuum conveyor is a linear web conveyor that draws the nose wires against the first web.

10. The method as in claim 6 , wherein the first web is a carrier web that forms an upper panel portion of facemasks produced in the production line, and the second web is a binder web that is folded over an edge of the carrier web with the nose wires encapsulated between the carrier web and the binder web.

11. The method as in claim 6 , wherein the second web is a carrier web that forms an upper panel portion of facemasks produced in the production line, and the first web is a binder web that is folded over an edge of the carrier web with the nose wires encapsulated between the carrier web and the binder web.
