  • Publication number: 20130232714
    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. The sheet is elastically contracted. The sheet may be elastically contracted by heat shrinkable material, by elastic strands and/or may be elastomeric. This arrangement allows the sheet to entangle and thereby fluff the tow fibers. Such fluffing is believed to improve cleaning performance.

  • Patent number: 6687943
    Abstract: The present invention relates to an anchoring device for the covering (9) of a fabric boom on its associated support, which provides for extraction of the totality of the piece of fabric (9), including its extremities. This extraction, accomplished by means of a roller extractor, is made possible by providing anchor studs (14) having an underlying recess and extending from the upper surface of the support (1-3), through the use of articulated lever-shaped connecting grips (5) on support (1-3) having an arm that exerts pressure on appendages (15) of the piece of fabric (9) without interfering with the heads of anchor studs (14), and lateral shoulders (13) on support (1-3) configured in such a way that they define between them a determinate space from which neither anchor studs (14) nor connecting grips (5) emerge.
