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.
Claims8
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;
- wherein the belt includes a first peripheral edge and a second peripheral edge extending along a longitudinal direction of the belt, the first peripheral edge being folded inwardly to a first width that does not reach a central line extending in a widthwise direction of the belt, and the second peripheral edge being folded inwardly to a second width that exceeds a central widthwise line of the belt;
- wherein the first and second peripheral edges are integrally sewn to the belt using a sewing thread coated with a polydimethylsiloxane adhesive, the sewing thread being manufactured by immersing a fiber thread in liquid polydimethylsiloxane to impregnate the fiber thread, withdrawing the impregnated fiber thread from the liquid polydimethylsiloxane, and subsequently drying the thread to form a dried polydimethylsiloxane adhesive coating thereon;
- a finishing space 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;
- an extension portion formed by the second peripheral edge extending over at least a portion of the first peripheral edge;
- a flexible band attached to a surface of the extension portion such that a distal end of the extension portion remains partially exposed, the flexible band being sewn to the extension portion using the sewing thread coated with a polydimethylsiloxane;
- and
- a binding portion formed by abutting both longitudinal ends of the belt without a height difference and sewing the abutted ends together using the sewing thread coated with the polydimethylsiloxane adhesive.
