Title: Method for hemming fabric using a hot melt adhesive

Abstract: A method and apparatus for forming a longitudinal hem along one edge of a fabric using a hot melt adhesive for securement of the hem. The fabric is advanced along a predetermined path of travel while one longitudinal edge portion of the fabric is directed through an elongate heating chamber and heated to an elevated temperature. The heated edge portion of the fabric then passes through a folding station and the fabric is folded to form a hem. A stream of molten hot melt adhesive is deposited between the overlying fabric layers which define the longitudinal hem and pressure is applied to the hem to cause the molten adhesive to spread and penetrate into the fabric layers and to also prevent relative movement between the fabric layers until the adhesive is sufficiently cooled to secure the hem together.
