Abstract: An apparatus for fabricating gasket pads for sealing a drum of a drier and a gasket pad fabricated. The apparatus automates the operations of guiding a strip of felt textile, cutting a portion of the felt textile by a predetermined length, butting both ends of the cut felt textile portion to each other without a difference in height, and sewing the both ends of the cut felt textile portion. Since gasket pads are fabricated by the automated operations instead of manual operations dependent of the experiences of workers, the same gasket pads can be fabricated with high-quality.
