Patent number: 7007581Abstract: A rotary anvil is outfitted with pins protruding from the base of an axially extending channel along the surface of the anvil. A cutting mat having a generally elongate body includes first and second locking members projecting from opposite axial ends thereof. The cutting mat is installed on the anvil such that the first and second locking members are positioned within the channel over one of the pins. The cutting mat may include a foot extending from the first locking member that includes a pin receptacle that seats down over the pin. Alternatively, a lockup device may be provided to temporarily secure the cutting mat to the rotary anvil. The lockup device includes a pin receptacle on the bottom surface thereof adapted to seat down over the pin. The first and second locking members of the cutting mat are then installed into the channel in cooperation with the lockup device.Type: GrantFiled: May 21, 2003Date of Patent: March 7, 2006Assignee: Day International, Inc.Inventors: John R. Elia, Jerry Shelton, Ronnie E. Bryson

Patent number: 7008513Abstract: The present invention is a method for making a roll cover and a roll cover, wherein at least one material is applied to the surface of the roll or a base substrate. In a first embodiment, a single material is applied as a flowable phase. A uniform coating of the material is applied to the roll, and upon setting of the material, such as by cooling, curing, or other means, a smooth and permanent roll cover is formed upon the surface of the roll. In another embodiment, at least two materials are applied in flowable phases to the surface of the roll. The first material may be a sacrificial, removable first material, applied to the surface of the roll cover in a preselected pattern. After the sacrificial material has been applied, a second material, such as a functional resin, is applied to the surface of the roll cover with the sacrificial material removed after the second material has set. In another embodiment, the use of sacrificial material is avoided and the material is applied in a predetermined pattern.Type: GrantFiled: December 31, 2002Date of Patent: March 7, 2006Assignee: Albany International Corp.Inventors: Francis L. Davenport, Maurice Paquin

Patent number: 6976284Abstract: The paint roller cover extender is a paint roller cover accessory that would allow the corner areas of a room to be painted in one motion using a conventional paint roller. The product would feature a cylindrical cap having the same diameter as a roller cover, a closed end, and an open end with an elastic band woven into the inner surface near the open edge. The elastic band would allow the unit to be easily snapped over and secured to the end of a roller cover. The paint roller cover extender would be made of the same material as the roller cover. In use, the standard roller cover would be used to apply paint to one section of a corner while the extender would apply paint at a right angle to the other wall of the corner. The paint roller cover extender could be sold as an after purchase accessory for conventional paint roller covers, or it could be packaged as a unit with a paint roller and cover.Type: GrantFiled: March 20, 2003Date of Patent: December 20, 2005Inventors: Peter A. Manfredi, Peter J. Pompeii

Patent number: 6942607Abstract: A charge roller utilizes a foam rubber substance where epichlorohydrin oxide rubber and an acrylonitrile butadiene rubber are mixed at a ratio of 5:95, or utilizing a crosslinking rubber substance made of epichlorohydrin oxide rubber and acrylonitrile butadiene rubber having a polar low molecular polymeric characteristic, thus allowing the charge roller to maintain a low volume resistivity of 107 ? cm to 108 ? cm. As a result, the surface of a photosensitive drum can be charged by a minimum charging voltage, to thereby significantly reduce an amount of ozone. Since a non-crosslinked low molecular polymeric substance existing at a resilient rubber is significantly reduced, the low molecular polymeric substance of the charge roller may not be migrated onto a surface of the photosensitive drum even if the charge roller is in contact with a photosensitive drum for a long time period during a stoppage of operation of an image forming apparatus.Type: GrantFiled: October 16, 2002Date of Patent: September 13, 2005Assignee: Samsung Electronics Co., Ltd.Inventors: Hae-Seog Jo, Hee-Won Jung

Patent number: 6932888Abstract: A flexible press cover which has an additional strengthening element in at least one of its two end regions. As a result, in the end region, the tensile strength and the tensile rigidity in the circumferential direction are increased with respect to that hitherto known in such a way that it is no longer necessary to clamp the press cover end region in between two components. Instead, the press cover according to the present invention is suitable to be fixed to the outer circumferential surface of a rotatable supporting element belonging to the cover carrying disk without the aid of an outer ring, a clamping band, clamping filament or the like. In the most beneficial case, the arrangement for fixing the press cover to the aforementioned supporting element is completely free of any kind of fixing elements which would be associated with the cover outer surface.Type: GrantFiled: February 5, 2004Date of Patent: August 23, 2005Assignee: Voith Paper Patent GmbHInventors: Uwe Matuschczyk, Andreas Meschenmoser, Joachim Grabscheid, Andreas Schütte

Patent number: 6918195Abstract: It is known from the art to mount a wire gauze (10) onto a drum (1) with a permeable drum jacket (8) under pretension, for example, for allowing air to flow through a web of material placed on said drum, said wire gauze optionally being disposed even at a distance to the drum jacket surface. The air thus flows more evenly across the surface of the web of material and no visible marks on the web of material, caused by the contact of the web with the intermediate space between the holes of the drum, occur. The wire gauze has to be elastically fastened on the front faces of the drum to compensate also for thermal stresses. According to the invention, preferably U-shaped spring elements (11) extending radially to the axis of the drum are fastened on the front face of the drum and on a tensioning ring (13) for the gauze provided on the level of the drum outer diameter.Type: GrantFiled: March 1, 2002Date of Patent: July 19, 2005Assignee: Fleissner GmbH & Co., MaschinenfabrikInventor: Gerold Fleissner
