  • Patent number: 11375867
    Abstract: A cleaning article defining an XY plane and a Z direction perpendicular to the plane. The cleaning article has discrete tufts of tow fibers bonded to a carrier sheet by primary bonds. The discrete tufts have secondary bond lines external to the tufts. The secondary bond lines interrupt the Z-direction thickness of the tufts, to provide channels for improved collection and retention of debris from a target surface. The tufts are created by slits between the primary bonds and secondary bonds, which yield plural tuft sizes. The slits may be transversely unequally spaced between adjacent bonds.

  • Patent number: 9198553
    Abstract: A cleaning article optionally removably attachable to a handle and comprising tow fibers and at least one sheet joined together in a layered construction. The cleaning article is generally planar. An elastically contracted panel is joined to the plane of the fibers or the sheet. The elastic causes the panel to contact and extend outwardly from the plane of the cleaning article. By extending outwardly from the plane of the cleaning article, the panel can directly entangle the fibers or disrupt the sheet, to promote fluffing of the tow fibers.

    Abstract: A structure for automatically rotating a spiral rod is provided. The structure allows a dusting cloth to be turned into a spiral shape along the spiral rod by rotating a rotating element, and, while the rotating element is being rotated, a torsion spring generates a restoring torque. Once the rotating element is no longer rotated, a pulling element pressing against the teeth inside the rotating element retains the rotating element and thus keeps the dusting cloth in the spiral shape. When the pulling element is subsequently pulled away from the teeth of the rotating element, the rotating element automatically rotates in the reverse direction due to the restoring torque of the torsion spring.
