Method and system for manufacturing facemasks in a production line
An automated system and method for the manufacture of facemasks from a web of a textile product in a production line is provided. The web is conveyed in the production line along a machine direction. A first tie is attached at a tie attaching station to the web of the textile product, such that the first tie extends from the web in a cross-machine direction perpendicular to the machine direction. The web and first tie are cut at a cutting station in the cross-machine direction across a width of the web in the cross-machine direction to form a facemask separate from the web.
1. An automated method for manufacturing facemasks from a web of a textile product in a production line, comprising:
conveying the web of the textile product in the production line along a machine direction;
attaching, at a tie attaching station, a first tie to the web of the textile product in a cross-machine direction such that the first tie extends in the cross-machine direction, wherein the cross-machine direction is perpendicular to the machine direction; and
cutting, at a cutting station, the web and the first tie in the cross-machine direction across a width of the web in the cross-machine direction to form a facemask separate from the web.
2. The automated method of claim 1 , wherein the cutting station is disposed downstream of the tie attaching station with respect to the machine direction.
3. The automated method of claim 1 , wherein neither the web nor the facemask is rotated prior to attaching the first tie.
4. The automated method of claim 1 , wherein attaching the first tie to the web includes attaching the first tie to a bottom face of the web opposite a top face of the web.
5. The automated method of claim 4 , further comprising attaching a second tie to the top face of the web such that the second tie extends in the cross-machine direction and overlaps the first tie.
6. The automated method of claim 5 , wherein attaching the first tie to the web includes ultrasonically bonding the first tie to the web, and wherein attaching the second tie to the web includes ultrasonically bonding the second tie to the web.
7. The automated method of claim 4 , further comprising attaching the second tie to the first tie.
8. The automated method of claim 1 , further comprising feeding the web onto a circumferential surface of a rotating wheel at a web feeding station upstream of the tie attaching station with respect to the machine direction.
9. The automated method of claim 8 , further comprising temporarily securing the first tie to the circumferential surface of the rotating wheel at a first tie arranging station before feeding the web onto the circumferential surface of the rotating wheel at the web feeding station.
10. The automated method of claim 9 , wherein the first tie is temporarily secured to the circumferential surface of the rotating wheel by a section device associated with the rotating wheel.
11. The automated method of claim 9 , wherein feeding the web onto the rotating wheel includes conveying the web on top of the first tie such that the bottom face of the web contacts the first tie.
12. The automated method of claim 11 , further comprising arranging the second tie on the top face of the web such that the second tie extends in the cross-machine direction and overlaps the first tie.
13. The automated method of claim 11 , further comprising temporarily securing the second tie on the top face of the web using a suction device associated with the rotating wheel.
14. The automated method of claim 1 , wherein cutting each of the web and the first tie includes cutting the first tie along a center line of the first tie to form a trailing tie on a first facemask and a leading tie on a second facemask.
15. The automated method of claim 1 , wherein the cutting station is disposed downstream of the tie attaching station with respect to the machine direction such that the first tie is attached to the web before each of the web and first tie is cut across the width of the web in the cross-machine direction.
16. The automated method of claim 1 , wherein the step of cutting the web and the first tie to form the facemask is repeatedly performed at a rate such that facemasks are formed at a rate between about 200 facemasks per minute and about 700 facemasks per minute.
