A cartridge for a pagewidth inkjet printer has a body configured to fit in a cradle of the inkjet printer. The three spindles are positioned to form a triangle of platen supports where the rotational-centers of each of the spindles are positioned at the center of the annular width of the platen abrading surface. A pressing device presses the fed-in article to the adhering drum and adhering the label. The eccentric rotor includes a printed wiring board, a cylindrical bearing for insertion of a shaft, and a weight which are integrated to have a flat disk shape by resin molding. Also, the superabsorbent polymer thus formed tends to disperse better and remain adhered to the absorbent andor thermoplastic fibers, providing a stable and uniform absorbent composite for various end use applications.
