Abstract

A method and associated system for cutting and placing individual nose wires in a facemask production line include supplying a continuous wire from a supply source to a cutting station where the continuous wire is cut into individual nose wires having a defined length. The nose wires are then conveyed to a treatment station prior to being deposited onto a carrier web. At the treatment station, a surface treatment is performed on a side of the nose wires that results in an increased surface attachment of the nose wires to the carrier web.

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;
with a treatment station upstream of the cutting station treating the continuous wire with a surface treatment, or with the treatment station downstream of the cutting station, treating the nose wires with the surface treatment;
from the cutting station, conveying the individual nose wires onto a carrier web with a pair of delivery rollers that deposit the nose wires along an edge of the carrier web corresponding to a top edge of a facemask without reorienting the nose wires that leave the cutting station; and
wherein at the treatment station, the surface treatment is performed to an underside of the continuous wire or the nose wires such that the nose wires conveyed by the delivery rollers have the surface treatment applied to the underside thereof that lies against the carrier web resulting in an increased surface attachment of the nose wires to the carrier web.

2. The method as in claim 1 , wherein the treatment station is downstream of the cutting station and the surface treatment is performed on the individual nose wires.

3. The method as in claim 2 , wherein the carrier web and attached nose wires are conveyed from the treatment station to a folder and bonder wherein the nose wires are encapsulated in a binder web that is folded over an edge of the carrier material and bonded to the carrier material.

4. The method as in claim 1 , wherein the surface treatment comprises applying an adhesive onto the underside of the nose wires or the continuous wire, the adhesive having sufficient tack for the nose wires to adhere to the carrier web.

5. The method as in claim 4 , wherein the adhesive is a pressure-sensitive adhesive, and further comprising pressing the nose wires onto the carrier web after application of the adhesive.

6. The method as in claim 4 , wherein the adhesive is sprayed onto the underside of the nose wires or the continuous wire.

7. The method as in claim 4 , wherein the adhesive is coated onto the underside of the nose wires or the continuous wire.

8. The method as in claim 1 , wherein the surface treatment comprises altering a surface characteristic of the underside of the nose wires or the continuous wire.

9. The method as in claim 8 , comprising abrading the underside of the nose wires or the continuous wire.

10. The method as in claim 9 , wherein the abrading is done mechanically by contacting the underside of the nose wires or the continuous wire with an abrasion device.

11. The method as in claim 9 , wherein the abrading is done chemically by applying an abrasive chemical to the underside of the nose wires or the continuous wire.

12. The method as in claim 8 , comprising defining a pattern into the underside of the nose wires or the continuous wire that increases surface roughness.

13. The method as in claim 12 , wherein the pattern is etched with a laser.

14. The method as in claim 12 , wherein the pattern is defined by a crimp roller.
