Patent number: 10450161Abstract: A roll holder includes a plurality of holder members to fit in and hold axial ends of any of a first roll with a first inner diameter and a second roll with a second inner diameter greater than the first inner diameter. Each holder member includes a base opposed to an axial end of any of the first roll and the second roll; a plurality of support switches; and a lock. The support switch is movable in an axial direction between a support position to support the second roll with the second inner diameter and a retracted position retracted from the support position to support the first roll with the first inner diameter. The lock locks movement of the plurality of support switches and releases locking of movement of the plurality of support switches when each of the plurality of holder members is fitted in the first roll.Type: GrantFiled: January 17, 2017Date of Patent: October 22, 2019Assignee: RICOH COMPANY, LTD.Inventor: Ryo Honda

Patent number: 9662697Abstract: A take-up device includes a fluid-pressure device, a pressure detection device, a pressure calculation mechanism, and a controller. The fluid-pressure device is a device for expanding and contracting a mandrel. The pressure detection device detects a pressure of a hydraulic fluid in the fluid-pressure device. The pressure calculation mechanism calculates a tightening pressure acting on the mandrel, based on the pressure detected by the pressure detection device. The controller controls the fluid-pressure device. Also, the controller performs position control until the number of turns of a strip reaches a value. The controller performs constant-pressure control after the number of turns of the strip reaches the value.Type: GrantFiled: November 28, 2012Date of Patent: May 30, 2017Assignee: TOSHIBA MITSUBISHI-ELECTRIC INDUSTRIAL SYSTEMS CORPORATIONInventor: Minoru Tachibana

Patent number: 7947149Abstract: A web of a first sheet material and a web of a second sheet material are laminated together by a process wherein the sheet materials are wound, in an interleaved relationship, upon a roller having a radially displaceable outer surface. The roller and webs and then subjected to heating and/or a low-pressure environment so as to complete the lamination. A body of adhesive material, such as a hot melt adhesive, may be interposed between the webs and the heating or low pressure environment can activate this adhesive. Further disposed are particular configurations of rollers with radially displaceable surfaces.Type: GrantFiled: January 21, 2008Date of Patent: May 24, 2011Assignee: United Solar Ovonic LLCInventors: Arthur Myatt, Gregory Demaggio, Kevin Beernink, Kermit Jones, Kenneth Lord

Patent number: 7922114Abstract: A winder in which the jaws of the mandrel expand automatically by the weight of the reel, without introducing external energy. The winder has a mandrel of horizontal axis (A) whose jaws are expandable by means of links hinged to the end of a sliding pull rod and connected to the frame by a hinged connecting rod. The winder includes a rocker connected to the frame by a fixed pivot axis (D) and to the mandrel by the physical embodiment of the axis of rotation (A), the two axes (D, A) are parallel. The rocker moves the mandrel vertically between a raised loading position and a lowered use position under the weight of a reel and it brings about, simultaneously, sliding of the pull rod, automatic expansion of the jaws, and automatic clamping of the reel.Type: GrantFiled: July 4, 2007Date of Patent: April 12, 2011Inventors: Pierre Marcelli, Julien Marcelli

Patent number: 7905444Abstract: A carbon ribbon shaft is provided for a barcode printer and includes a shaft rod and at least one first rotation member and one second rotation member. The shaft rod has an end coupled to a housing of the barcode printer. The first and second rotation members are fit over the shaft rod. Arranged between inside of the first rotation member and the shaft rod is a resilient element that allows the first rotation member to effect resilient rotation with respect to the shaft rod. The first rotation member has an outer surface forming sliding-resistant resilient tabs. Arranged between inside of the second rotation member and the shaft rod is a resilient element that allows the second rotation member to effect resilient rotation with respect to the shaft rod. The second rotation member has an outer surface forming sliding-resistant resilient tabs. The surfaces of first and second rotation members receive a carbon ribbon roll of the barcode printer to fit thereon.Type: GrantFiled: January 7, 2009Date of Patent: March 15, 2011Assignee: TSC Auto ID Technology Co., Ltd.Inventor: Ching-Wen Chen

Publication number: 20090218434Abstract: An adjustable diameter tape roll cartridge core assembly which permits various different tape rolls, manufactured, for example, by various different tape roll manufacturers, and characterized by different internal diameter dimensions, to be fixedly and securedly mounted upon the tape roll cartridge core member of a tape roll dispensing cartridge assembly of a carton or case sealing machine. The core assembly comprises an expandable and contractible annular ring member whereby the external diametrical extent of such expandable and contractible annular ring member is adjustable so as to in fact be capable of tightly engaging the inner peripheral surface portion of any one of various different tape rolls having various different internal diameter dimensions.Type: ApplicationFiled: February 29, 2008Publication date: September 3, 2009Inventors: Bryce J. Fox, William J. Menta

Patent number: 7322761Abstract: A spool, such as supply for a wide-format printer, is provided. The spool comprises a spindle for slidingly receiving an outer shaft, which is typically the core of a roll of print media. A first resiliently deformable gripping ring is circumferentially mounted about the spindle, and a compression mechanism is provided for axially compressing the gripping ring. The axial compression causes radial expansion of the gripping ring, thereby urging the gripping ring into gripping engagement with the outer shaft received on the spindle.Type: GrantFiled: September 12, 2005Date of Patent: January 29, 2008Assignee: Silverbrook Research Pty LtdInventors: Kia Silverbrook, Nagesh Ramachandra, Jan Waszczuk

Patent number: 6623193Abstract: An ink ribbon cartridge has first and second tubes (130, 132) for holding an ink ribbon. The tubes have slots formed in each end. Spindles (140, 142, 162, 164) are attached at the ends of the tubes. The spindles have a disk portion and an end which is received by tube slots. One of the spindles has a cantilevered member (196) which engages a slot of a tube and allows rotation of the tube in only one direction. The cantilevered member has an end having a radial edge (200) and a ramp (202) adjacent the straight side. Rotation of the spindle in one direction abuts the radial edge against a wall of the slot thus providing a positive drive and allowing rotation of the tube with the spindle. Rotation of the spindle in a second direction opposite to the first direction causes the ramp side to contact and slide along a wall of the slot, thus deflecting the cantilevered member inward toward the center of the spindle.Type: GrantFiled: November 27, 2001Date of Patent: September 23, 2003Assignee: Nu-kote International, Inc.Inventor: Carl William Holland

Patent number: 6533214Abstract: A device to support and drive a winding bar or tube-shaped spindle designed to roll or unroll bolts of material of the type containing a guiding bearing and a guided bearing, each made up of a fixed casing in which a shaft can move axially, having an end designed to be able to butt against, at one of its ends which adapted for this purpose, the winding bar or the spindle, the shaft of the guiding bearing being driven to rotation by means of a sleeve rotating in the casing by a motor and the interior of the sleeve can move the shaft axially, all while being linked in rotation while the shaft of the guided bearing is mounted in free rotation. Each fixed casing is in the shape of a cylindrical casing of a jack in the watertight chamber which can move, under action of fluid, a piston attached coaxially to the guiding shaft or to the guided shaft such that the cylindrical casing is equipped at its lower end in a manner that allows extraction of the end of the shaft.Type: GrantFiled: April 25, 2000Date of Patent: March 18, 2003Assignee: Guttin Christian SarlInventor: Christian Guttin
