  • Method and apparatus for producing a continuous web from a block of material
    Patent number: 6269724
    Abstract: An apparatus for forming a continuous web of material from a block of material is disclosed. The block is preferably a cylindrical block having a base and a generally vertical central axis extending generally orthogonally from the base. The apparatus comprises a rotatable platen such that the block may be rotatably supported, and a milling cutter for displacing portions of the block defining a displaced portion near the base of the block. A blade is positioned generally parallel to the central axis of the block, the blade positioned to cut into the block a predetermined distance from the central axis. The blade has a portion operatively disposed within the displaced portion of the block. The apparatus also comprises a drive mechanism for rotating the platen; as well as a linear drive mechanism for linearly decreasing the predetermined distance of the blade from the central axis.

  • Wipes having a substrate with a discontinuous pattern of a high internal phase inverse emulsion disposed thereon and process of making
    Patent number: 6168852
    Abstract: A wipe comprising a high internal phase inverse emulsion disposed in a discontinuous pattern on a substrate. The pattern provides areas coated with the emulsion and areas free of the emulsion. Preferably the emulsion is disposed so that the surface area to volume ratio of the emulsion is minimized. The emulsion locally expresses water during use upon the application of pressure to the wipe. The water is useful for cleaning. The discontinuous pattern of the emulsion provides regions of the substrate which are wetted during use and regions which may remain dry. The wetted regions transfer water to the surface to be cleaned. The dry regions then remove the water from the surface for more efficacious cleaning.
