Patent number: 9670020Abstract: A reel unwinder including a first unwinding position, in which a first reel is positioned; a second unwinding position, to which the first reel is transferred when it is replaced with a second reel; a stand-by position, in which the second reel is kept in stand-by; a first unwinding member adapted to start rotation of the second reel when the first reel is replaced with the second reel. Moreover, the unwinder includes a second unwinding member, with at least one endless flexible element. The endless flexible element extends from the first unwinding position to the second unwinding position, and is adapted to maintain the first reel in contact with the second unwinding member and in rotation by the second unwinding member in the first unwinding position, in the second unwinding position and while it is being transferred from the first unwinding position to the second unwinding position.Type: GrantFiled: November 15, 2012Date of Patent: June 6, 2017Assignee: Fabio Perini Packaging S.p.A.Inventors: Roberto Morelli, Angelo Benvenuti

Patent number: 9566807Abstract: A printer takes up slack in media while suppressing excessive rewinding, and can check the movement of a movable member that moves following change in tension on the media. The printer drives the supply motor in a first operating mode in a slack removal operation that rewinds the recording paper (media) onto a paper roll 2, and stops driving the supply motor when the tension lever (movable member) moves from a slack-side first position toward a second position. In the movement checking operation, the supply motor is driven in a second operating mode with greater output than the first operating mode, rewinds the recording paper on the paper roll, and sets the tension lever to the second position.Type: GrantFiled: December 28, 2015Date of Patent: February 14, 2017Assignee: SEIKO EPSON CORPORATIONInventor: Yuki Takizawa

Patent number: 8915460Abstract: The invention relates to a device for feeding a quasi-endless material web (4) to a manipulation device (19) receiving the material web (4), wherein a feed tension unit (8) is provided, through which the material web (4) is fed in an S-shape. The feed tension unit (8) comprises a pivotal feed dancer roller (12), the angle positions thereof being captured by a feed angle sensor (34) and fed to a control unit (36), by means of which the material web (4) is fed or retracted by a dispenser roller motor (3) in the direction of the manipulation device (19), depending on the deviation of the angle position from a reference angle position. Substantially uniform tension in the material web (4) is thereby ensured, even under extreme operating conditions.Type: GrantFiled: April 9, 2010Date of Patent: December 23, 2014Assignee: A. Raymond et CieInventors: Martin Büsch, Tobias Buss

Patent number: 7067833Abstract: An apparatus for wrapping harvested crop material into bales wherein the wrapping material web is drawn off from a wrapping media supply which rotates about a vertical axis while, at the same time, the bale rotates about a horizontal axis. A sensor is provided which signals a tear in the wrapping media web or the absence of material media. The sensor may be optical ultrasonic or sense electromagnetic radiations of different frequency ranges, as appropriate for the media of which the wrapping media involved. A position sensor is provided which activates an evaluation of signals from the sensor that a signal is produced when the web tears or is absent.Type: GrantFiled: November 8, 2002Date of Patent: June 27, 2006Assignee: Lely Enterprises AG a Swiss Limited Liability Co.Inventor: Christoph Ramm
