Each unit prism, when viewed in a direction parallel to the arrangement direction of the unit prisms, has an uneven polygonal-line-shaped contour and, with reference to raised portions (37) defined by the polygonal-line-shaped contour of each unit prism, the distance between a top (37a) of each raised portion, a farthest point from the body portion in the raised portion, and the body portion in the normal direction of the body portion is not constant. The optical sheet can prevent significant problems when it is superimposed on another member.Type: ApplicationFiled: February 25, 2010Publication date: December 8, 2011Applicant: Dai Nippon Printing Co., Ltd.Inventors: Hiroshi Kojima, Satoshi Goishihara, Satoko Maenishi

Patent number: 8051757Abstract: A method of cutting, simultaneously on two axes (X, Y) perpendicular to each other, of a sheet or web of paper and other graphic or photographic substrates (10) with series of images, comprising the steps of feeding forward the substrate sheet or web (10) to a direction (F), detecting the speed of sheet or web (10) feed and the speed at which the distance is varying between image reference marks (11) and the ideal feed direction, determining a correct cutting line (TX) in a transverse direction to the feed direction (F) of the sheet or web by data processing according to trigonometric relations through a microprocessor to obtain the angle of parallelism defect of the image with respect to the ideal feed forward direction, aligning suitable mobile means (4) of transverse cutting with the desired cutting line (TX) by means (5) for shifting the transverse cutting means.Type: GrantFiled: October 25, 2006Date of Patent: November 8, 2011Assignee: Fotoba International S.R.L.Inventor: Valter Maddalon

Publication number: 20110232440Abstract: An apparatus for slicing food products includes a product feed which feeds a product to be sliced along a product feed direction through a cutting plane in which at least one cutting blade moves. The position of the cutting blade is adjustable relative to the product. A control unit is provided which is designed to automatically adjust the position of the cutting blade for the optimization of the blade wear.Type: ApplicationFiled: March 25, 2011Publication date: September 29, 2011Inventor: Günther Weber

Publication number: 20110197728Abstract: Systems and methods are provided for cutting slices of food product from a larger portion of the food product, whereby the systems and methods can reduce down-time associated with some of the portions of the equipment during cleaning. Components of the system requiring more frequent cleaning can be readily disconnected from those components requiring less frequent cleaning. Further, substitute components can be connected to those components requiring less frequent cleaning to reduce their down-time while the other components are being cleaned.Type: ApplicationFiled: February 12, 2010Publication date: August 18, 2011Applicant: Kraft Foods Global Brands LLCInventors: Rory J. Redemann, Timothy T. Watson

Publication number: 20110179750Abstract: An improved net cutting assembly that may be used with an agricultural baler net wrapping system. More particularly, an up-cut net knife for improved cutting of wrapping material (e.g., a net) used to wrap bales of crop material in an agricultural baler. The up-cut net knife assembly improves net cutting performance by providing an up-cut net knife that moves in the same direction as the net whereby the motion of the net helps the knife get into the cut position. Further, embodiments of the up-cut knife assembly move the up-cut knife cutting edge at substantially the same speed and in the same direction as the net to be cut. This motion of the up-cut knife allows the up-cut knife to be lifted up into the net motion using a driver and then to continue on with no relative motion—or at least minimal relative motion of the knife to the net—until the knife gets into the cut position. In the cut position, the knife stops and the net is pulled against the knife blade resulting in cutting the net.Type: ApplicationFiled: January 22, 2010Publication date: July 28, 2011Applicant: CNH AMERICA LLCInventor: Kevin M.

Publication number: 20100322692Abstract: A sheet processing apparatus includes a conveying motor for conveying a sheet along a conveying path, a skew detecting unit configured to detect a quantity of skew of the conveyed sheet, a hole punching section arranged downstream from the skew detecting unit, an attitude control unit configured to carry out skew correction by changing tilt angle of the hole punching section in accordance with the quantity of skew, a detecting unit configured to detect the forward edge and the rear edge of the sheet conveyed into the hole punching section, and a control unit configured to control the conveying motor to control the conveying speed of the sheet. During a period from when the detecting unit detects the forward edge of the sheet until the detecting unit detects the rear edge, the sheet is decelerated from a first conveying speed to a second conveying speed.Type: ApplicationFiled: August 31, 2010Publication date: December 23, 2010Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA TEC KABUSHIKI KAISHAInventors: Ken Iguchi, Hiroyuki Tsuchihashi, Tetsuhiro Morita

Publication number: 20100147122Abstract: A torch guide device for cutting target material is presented, the torch guide device including a torch cradle assembly coupled to a rail assembly. The torch cradle assembly is configured for holding a torch to align a torch tip of the torch to the target material. The torch cradle assembly is movable along the rail assembly for cutting the target material along a cutting path. The connector member couples the torch cradle assembly to the rail assembly. The connector member comprises a pivot for pivoting the torch cradle assembly relative to the rail assembly. The torch cradle assembly, in a first position, pivots about the pivot to engage at least a portion of the rail assembly to establish an orientation of the torch tip relative to the target material.Type: ApplicationFiled: December 16, 2009Publication date: June 17, 2010Inventors: Netta Jewell Hurt, Mitchell Loyd Hurt
