Publication number: 20160229215Abstract: A method for applying a security device (e.g., a micro-optic security thread) to a fibrous web during manufacture is provided. By way of the inventive method, the security device is preferably applied onto the fibrous web at or near a couch roll or similar tool of a paper machine when the fibrous web constitutes a sufficiently consolidated, fully formed wet web. Papers made in accordance with the inventive method, when subjected to the Circulation Simulation Test, showed minimal damage at the paper/security device interface. Moreover, the surface-applied security devices showed acceptable levels of intaglio ink adhesion, and the papers had higher cross-direction (CD) tensile strength and much less show-through on opposing sides thereof.Type: ApplicationFiled: February 11, 2016Publication date: August 11, 2016Applicant: Crane & Co., Inc.Inventors: Giles D.

Publication number: 20160216726Abstract: A force-sense-imparting operation device including a stationary section, a rotating section, and an operation member. One of the stationary section and the rotating section includes an excitation coil and a first magnetic pole section, and the other includes a second magnetic pole section capable of opposition to the first magnetic pole section in a specific opposing direction. The first magnetic pole section forms a magnetic circuit with the first magnetic pole section due to the second magnetic pole section being excited in a state that the second magnetic pole section opposes the first magnetic pole section. The magnetic circuit encircles a periphery of the excitation coil on the cross section, the second magnetic pole section being arranged to separate from the first magnetic pole section with rotation of the rotating section.Type: ApplicationFiled: August 25, 2014Publication date: July 28, 2016Applicants: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.), KOBELCO CRANES CO., LTD.Inventors: Koji INOUE, Takashi HIEKATA, Tatsurou ASANO

Publication number: 20150152602Abstract: The invention generally relates to a security sheet or document having one or more enhanced watermarks. In one exemplary embodiment, the inventive security sheet or document is a single-ply paper that is made up of a paper layer including one or more watermarks, and a micro-optic security device (e.g., a patch or thread) that at least partially covers an upper or face portion of the watermark(s). The overlying patch or thread increases the durability of the watermark(s), thereby allowing for the watermark(s) as well as reduced fiber density areas therein to be made larger, and further allowing for the reduced fiber density areas to be made thinner. In a preferred embodiment, the micro-optic security device projects one or more synthetic images that coordinate or link in with the watermark design(s). In a more preferred embodiment, the micro-optic security device offers a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission.Type: ApplicationFiled: December 2, 2014Publication date: June 4, 2015Applicants: CRANE & CO., INC., CRANE SECURITY TECHNOLOGIES, INC., CRANE ABInventors: William Blake, Jeffrey Boody, Kraig M.
