NEW YORK — JPS Textile Group said Tuesday it is reorganizing its management personnel following the death last week of William Gray, chief operating officer of its subsidiary company, JPS Converter and Industrial Corp.

Gray, 63, died of a heart attack Jan. 9 at Greenville Memorial Hospital, Greenville, S.C.

Jerry E. Hunter, president of JPS Textile Group, has added Gray’s post of chief operating officer.

Carl Rosen, president of marketing and sales for the apparel and home furnishings group of JPS Converter and Industrial, will also be charged with yarn sales, cotton industrial fabrics marketing and sales, and fiber procurement. He reports to Hunter.

In addition, Reid McCarter has been named business manager for all JPS Converter and Industrial’s product lines.

Roger Muckenfuss will be taking on the post of director of manufacturing. McCarter has served in the firm in a variety of marketing, sales and product management positions. Most recently he served as director of manufacturing. McCarter reports to Rosen.

Muckenfuss, who reports to Hunter, had been a line manager.

Gray, who was slated to retire in June, joined the firm in 1959 as a sales and marketing associate for apparel and home furnishings fabrics, when the company was part of JP Stevens. When WestPoint Pepperell purchased Stevens in 1988, it sold several of Stevens’ apparel, home furnishings and industrial businesses to Odyssey Partners. Odyssey then formed JPS Textile Group.

Gray was named chief operating officer of JPS Converter and Industrial in May 1993.

Services for Gray were held last week in Greenville. He is survived by his wife, Patricia, and four sons, Richard, Lee, Andrew and David.
