Publication number: 20110039672Abstract: Conventional art has a structure consisting of a roll axis incorporating a structure of fine pores, and a roll unit provided around the outer circumference of a roll axis, wherein internal pressure of the roll axis is dispersed to the roll unit to make a fluid (gas-liquid) suction action, thus reducing the pressure loss and obtaining even distribution of the fluid (gas-liquid). As such, instead of a tubular roll axis, the structure of a roll axis is made fin-shaped or groove-shaped to maximize the action surface area that works on the inner pressure of the roll axis of the roll unit. However, other problems such as inefficiency of the fluid (gas-liquid) suction action and lack of mechanical strength of the roll axis remains.Type: ApplicationFiled: August 12, 2010Publication date: February 17, 2011Applicants: MASUDA SEISAKUSHO CO., LTD., MASROLL SYSTEMS INC.Inventors: Masanobu Masuda, Noriaki Masuda

Patent number: 7881646Abstract: A developing roller suppresses scattering of toner during a developing process and provides a further higher-quality electrophotographic image. The developing roller has a mandrel, an elastic layer provided on the circumference of the mandrel, and a surface layer provided on the circumference of the elastic layer. The surface layer contains a urethane resin serving as a binder and urethane resin particles dispersed in the binder, for forming convex portions on the surface of the surface layer. The surface of the urethane resin particles is partly covered with fine inorganic particles containing at least one element selected from silicon, titanium and aluminum and the urethane resin particles are in direct contact with the binder at the surface onto which the fine inorganic particles are not attached.Type: GrantFiled: March 8, 2010Date of Patent: February 1, 2011Assignee: Canon Kabushiki KaishaInventors: Minoru Nakamura, Kazuaki Nagaoka, Yoshiyuki Takayama

Publication number: 20100298107Abstract: The present utility model is a nylon conveyance roller used for the lifting platform loader of aircraft cargo transit wagon, wherein there is a tunnel going through the said roller for placing the axle. The tip and toe of the said roller are provided with plane structure, and the outer surface of the said roller is frosted texture. The material Nylon, designed for making the said conveyance roller, is suitable. It can increase the friction between the roller and the floor of container and container plate during cargo conveyance, making skidding conditions or noise during rotating friction unlikely. By using nylon as material, the said roller can boast good wear resistance, low noise, a slim likelihood of skidding condition, and environmental compliance.Type: ApplicationFiled: June 24, 2009Publication date: November 25, 2010Applicant: EASYROLL TECHNOLOGY (HK) LIMITEDInventor: CHING FONG HON

Patent number: 7824514Abstract: A method of producing a stretch laminate exhibiting reduced defects from a mechanical activation process can include providing a nipping member. The nipping member can have a first nip region and a non-nip region adjacent to the first nip region. A first substrate and an elastic element are provided to the nipping member. The first substrate and the elastic element are joined in a face to face relationship with adhesive therebetween, thereby creating an intermediate laminate. The intermediate laminate has a first tack down region and an activation region adjacent the first tack down region. A portion of the first tack down region passes through the first nip region, and a portion of the activation region passes through the non-nip region of the nipping member. The activation region of the intermediate laminate is mechanically activated, thereby creating the stretch laminate.Type: GrantFiled: December 1, 2005Date of Patent: November 2, 2010Assignee: The Procter & Gamble CompanyInventors: Anand Rudra Venkitaraman, George Stephen Reising

Publication number: 20100210434Abstract: The present invention is a laser engravable embossing roll exhibiting improved wear characteristics and life span through the use of an epoxy resin based material. Specifically, the embossing roll according to the present invention can be produced using standard laser engraving techniques that have heretofore been applied to rubbers. Rubber rolls, while produced significantly faster than engraved steel rolls, have the disadvantage of poor life span due to wear. The epoxy based resin rolls of the present invention overcome these disadvantages by being quickly and easily produced using laser engraving but exhibiting significantly improved wear characteristics.Type: ApplicationFiled: October 30, 2009Publication date: August 19, 2010Inventors: Galyn A.

Publication number: 20100199868Abstract: A printing cylinder for a printing machine or printing sleeve for forming a printing cylinder that includes a plurality of cups for forming a supporting inner structure of the printing cylinder or printing sleeve. Each cup includes a central disc, a radially outer edge, and a first conical surface part. The first conical surface part of one cup at least partially bears against an adjacent cup in order to form a connection between the one cup and the adjacent cup. The radially outer edges of the plurality of cups together define a substantially cylindrical surface.Type: ApplicationFiled: September 2, 2009Publication date: August 12, 2010Applicant: Mueller Martini Druckmaschinen GmbhInventors: Michiel Van Der Meulen, Gerrit Wolters

Patent number: 7571542Abstract: A method of forming a roll for embossing aluminum sheet, and the associated roll, the method comprising subjecting a surface of a steel roll to at least the steps of, in order: blasting treatment, electrolytic treatment with 1,000 to 20,000 C/dm2 of electricity in which the steel roll is used as the anode, and chromium plating treatment. An aluminum sheet embossing roll produced by the method of the present invention has on the surface thereof peaks, or asperities, which are of uniform height and very numerous. As a result, aluminum sheets obtained using such a roll, when employed as lithographic printing plate supports, have excellent printing characteristics, particularly a long press life and a high sensitivity.Type: GrantFiled: January 21, 2005Date of Patent: August 11, 2009Assignee: FUJIFILM CorporationInventors: Atsuo Nishino, Hirokazu Sawada, Akio Uesugi
