ABSTRACT Apparatus for making a disposable headdress in which the edge of the cap fabric has been folded inward around the peripherally extending elastic cord to provide a smooth edge which contacts the wearer, and provides superior adhesion between the elastic cord and the cap fabric by utilizing an elastic cord and fabric which are coated with or made of thermoplastically compatible materials. The elastic cord and fabric are assembled by passing the fabric and the cord through a guide system which turns the fabric side edges down from a horizontal plane to a vertical plane while an edge guide lays the elastic cord under the fabric, and then turns the fabric under the cord to sandwich in the folded edge. Warm air preheaters heat the elastic cord and the fabric before completing the fabric fold around the cord. The folded edges with the cord inside pass between dual heat wheels which physically press the fabric to the cord and also seal the fabric edge to the inside of the crown. Pres- sure rollers press and cool the corded fabric contact to seal the cord and fabric together before then can separ- ate. A cool air generator is utilized after the pres- sure rollers to more firmly set the bond between the cords and the fabric. Finally, the sealed elastic cord fabric edge is raised slightly in the region where the end of the cap is formed just prior to transverse end sealing to insure capture of the cord end in the end seal and to eliminate any inward protrusions of the gathered sealed end which would press against the head of the wearer.
