Abstract
A drum sealing gasket of a washing and drying machine is disposed on an end of a drum. The drum sealing gasket includes a band-shaped belt manufactured by cutting a felt in which natural fiber and synthetic fiber are mixed. A finishing space is formed by folding both peripheral portions of the belt and sewing the peripheral portions to the body of the belt with an adhesive-coated sewing thread. An extension is formed on one of the folded peripheral portions to cover a portion of the other of the folded peripheral portions. A flexible band is added and sewn to the surface of the extension with an adhesive-coated thread. Both ends of the belt are bound without a height difference.

A drum sealing gasket of a washing and drying machine, the drum sealing gasket comprising:
- a band-shaped belt of a cut felt manufactured by mixing natural fiber that is a mixture of one or more among wool fiber, cotton fiber, hemp fiber, and silk fiber and synthetic fiber that is a mixture of one or more among polyolefin, polyester, polyamide, polyacrylic, rayon, and nylon;
- transverse-direction peripheral portions of the belt folded over the length of the belt, wherein one of the peripheral portions is folded such that the edge thereof does not reach the longitudinal centerline of the belt, the other of the peripheral portions is folded such that the edge thereof extends beyond the longitudinal centerline of the cut belt, and both the peripheral portions are integrally sewn with a body of the belt with a sewing thread coated with a polydimethylsiloxane adhesive;
- wherein a finishing space is provided in a transverse-direction central portion of the belt to extend in a longitudinal direction with a width of 2 mm to 15 mm such that a finishing portion provided on an end of a drum is tightly received therein;
- wherein the other of the peripheral portions is folded such that the edge thereof extends beyond the longitudinal centerline of the cut belt has an extension extending to cover a portion of the one of the peripheral portions folded such that the edge thereof does not reach the longitudinal centerline of the belt;
- and
- a flexible band added to a surface of the extension and sewn with the sewing thread coated with a polydimethylsiloxane adhesive so as to be integrated with the extension,
- wherein both ends of the belt to which the flexible band is sewn are brought into butt contact with each other without a height difference, and contact portions are sewn with the sewing thread coated with a polydimethylsiloxane adhesive to form a binding portion.
