A method of continuously forming a mophead is disclosed for making a non-woven fabric mophead of a cellulose and synthetic resin fiber blend by sealing and cutting the non-woven fabric including: (a) combining a plurality of non-woven continuous fabric sheets together in a composite superimposed stack; (b) intermittently moving the superimposed stack to a sealing station and forming at least one ultrasonic seal transverse to the length of the sheet and in the center area of the superimposed stack; (c) intermittently moving the superimposed stack to a cutting station; and (d) dividing the superimposed stack into mophead widths and simultaneously cutting a saddle portion and plural strips.

The method of continuously forming a mophead made of a nonwoven fabric of a cellulose and synthetic resin fiber blend by sealing and cutting the nonwoven fabric comprising the steps of: (a) combining a plurality of nonwoven continuous fabric sheets having a length, a width and a center area together in a composite superimposed stack; (b) intermittently moving said composite superimposed stack to an ultrasonic sealing station and forming at least one ultrasonic seal continuously and transversely to the length of the sheet in the center area of said composite superimposed stack; (c) intermittently moving said composite superimposed stack from said ultrasonic sealing station to a cutting station; and (d) dividing said composite superimposed stack transversely into mophead widths while simultaneously cutting the mopheads to include a saddle portion defined by said at least one ultrasonic seal and a pair of plural strips extending inwardly from the ends of the mophead and communicating with the uncut saddle portion.
