Abstract
Abstract 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. Pressure rollers press and cool the corded fabric contact to seal the cord and fabric together before they can separate. A cool air stream may be utilized after the pressure 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 tranverse 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
198 words
A disposable headdress comprising in combination, (a) a crown portion formed from a web of fabric continuously reversely folded upon itself to form an elongated stacked plurality of pleats extending longitudinally from one end of said web to the other, which pleats are small in width compared to their length and to the length of the web forming said crown portion, the outermost pleats having longitudinally extending marginal edges folded inward and secured to the inner surface of the crown, (b) stretched elastic cords extending longitudinally the full length of said web and secured substantially continuously thereto within the folded marginal edges of the longitudinally extending outermost pleats, each of said elastic cords in unstretched condition being shorter than the length of web to which it is secured and being stretchable to the full length of the web forming said crown portion, whereby when said elastic cords contract from their stretched to their unstretched condition the crown portion of the headdress is peripherally reduced in size, and (c) securement means fixedly securing together all of said stacked plurality of pleats and said elastic cords closely adjacent to each end of said folded web which forms said crown portion.
Claim 2
Dependent Claim
198 words
A disposable headdress comprising in combination, (a) a crown portion formed from a web of fabric continuously reversely folded upon itself to form an elongated stacked plurality of pleats extending longitudinally from one end of said web to the other, which pleats are small in width compared to their length and to the length of the web forming said crown portion, the outermost pleats having longitudinally extending marginal edges folded inward and secured to the inner surface of the crown, (b) stretched elastic cords extending longitudinally the full length of said web and secured substantially continuously thereto within the folded marginal edges of the longitudinally extending outermost pleats, each of said elastic cords in unstretched condition being shorter than the length of web to which it is secured and being stretchable to the full length of the web forming said crown portion, whereby when said elastic cords contract from their stretched to their unstretched condition the crown portion of the headdress is peripherally reduced in size, and (c) securement means fixedly securing together all of said stacked plurality of pleats and said elastic cords closely adjacent to each end of said folded web which forms said crown portion.
Claim 3
Dependent Claim
39 words
A disposable headdress as set forth in claim 1 wherein said elastic cords are raised in the region where said stacked plurality of pleats and said elastic cords are fixedly secured together to overlie said stacked plurality of pleats.
Claim 4
Dependent Claim
35 words
A disposable headdress as set forth in claim 1 wherein said elastic cords are provided with a coating which is fused to the adjacent surfaces of said crown fabric within the said folded marginal edges.
Claim 5
Dependent Claim
47 words
A disposable headdress as set forth in claim 1 wherein the said longitudinally extending marginal edges of said outermost pleats which are folded inward and secured to the inner surface of the crown are secured at regularly spaced intervals continuously along the length of said outermost pleat.
Claim 6
Dependent Claim
63 words
A disposable headdress as set forth in claim 1 wherein said crown portion is a fabric having a thermoplastic surface and wherein the said longitudinally extending marginal edges of said outermost pleats which are folded inward and secured to the inner surface of the crown are fused to said crown at regularly spaced intervals continuously along the length of the said outermost pleat.
Claim 7
Dependent Claim
102 words
A disposable headdress as set forth in claim 1 wherein said elastic cords are coated with a thermoplastic material and said crown portion is a fabric having a thermoplastic surface compatible with that with which said elastic cords are coated, wherein said elastic cords are fused to the adjacent surfaces of said crown fabric within the said folded marginal edges, and wherein the said longitudinally extending marginal edges of said outermost pleats which are folded inward and secured to the inner surface of the crown are fused to said crown at regularly spaced intervals continuously along the length of said outermost pleat.
Claim 8
Dependent Claim
94 words
A disposable headdress as set forth in claim 1 wherein said plurality of pleats are of substantially equal width and are stacked directly one above another with the folded edges thereof disposed in substantially parallel planes extending normal to the flat surfaces of the pleats, and wherein the elastic corded fabric edges are positioned out of the said parallel planes to overlie the surface of the adjacent pleats so that the corded edges are secured by the said securement means at a position slightly away from the longitudinally extending edge of the stacked pleats.
