ABSTRACT:
A reinforced viral resistant seam for an article of protective apparel constructed by arranging first and second thermoplastic webs and at least one reinforcing strip thermally bondable with the webs along a common seam edge. An ultrasonic welding wheel having a cutting edge immediately adjacent to the welding surface is used to form a viral resistant, comfortable, high tensile strength seam suitable for articles of protective apparel.
