  • Patent number: 8991737
    Abstract: A method and apparatus are provided for decelerating an inverter-controlled machine reel in a paper machine. The method includes detecting a break in a paper web from a machine reel, determining the inertia of the machine reel, determining continuously the angular speed of the machine reel, and determining continuously the torque required to decelerate the machine reel, on the basis of the determined inertia and angular speed, for the purpose of stopping the machine reel in a predefined time. The method also includes decelerating the machine reel electrically to stop the machine reel, in accordance with the determined torque, and using a mechanical brake when the rotation speed of the machine reel is lower than a predefined rotation speed and when the torque obtained by electrical deceleration is too small to stop the machine reel in a predefined time.

  • Patent number: 8939663
    Abstract: A ribbon tension control system for a printing system includes a ribbon tension control apparatus. The ribbon tension control apparatus is configured to engage a print ribbon that extends through the printing system for applying one or more inks in the print ribbon to one or more target objects as the print ribbon is pulled from an unwind spindle to a windup spindle in the printing system. The ribbon tension control apparatus also is configured to control tension in the ribbon in response to change in a torque applied to the windup spindle that is used to pull the ribbon through the printing system.

  • Patent number: 8695912
    Abstract: A reel comprises a motorized spool member about which a linear material can be wound. A housing surrounds the spool member and has a port through which the linear material extends. A motor controller detects when the linear material is pulled from the spool member through the port, and responds by operating a motor to rotate the spool member in an unwind direction. During this operation, the motor controller (1) uses a spool sensor system to detect an unwind rate at which the linear material is unwound from the spool member, (2) uses a translation sensor system to detect a pull-out rate at which the linear material is pulled through the port in the unwind direction, and (3) adjusts the motor speed based on the detected rates, to limit a length of unwound linear material between the spool member and the port to less than a predetermined length.

  • Publication number: 20040238677
    Abstract: Provided is a transfer device capable of maintaining a constant tension of band-shaped ribbon from the start till the end of operation requiring no action by a user. While band-shaped ribbon (F) is being supplied, a feed shaft unit (4) and a feed drive gear (3) rotate. In accordance with their rotations, a movable plate (6) screw-retreats so that the interval between the movable plate (6) and the surface of the feed drive gear (3) is increased in the axial direction. Consequently, the force of a coil spring (5) is reduced and the braking force (a force to press the surface of the feed drive gear (3) to stop its rotation) is gradually decreased.

  • Patent number: 6745976
    Abstract: A tape roller bearing is provided that prevents the development of an air film between the roller surface and the tape. The spool surface is made from porous material so that air flows through the spool surface. The porous material vents air uniformly over the roller surface, and the tape remains in direct contact with the roller, even at high speed. The speed of the tapes movement can be determined by measuring the speed of movement of the spool surface using an encoder disk and an encoder module.

  • Patent number: 6301862
    Abstract: It is desired to prevent disalignment of the edges of a folded sheet by smoothly feeding the sheet while keeping tension fluctuations to a minimum when the sheet is unwound from a paper roll set in a paper feed unit to a packaging unit even though the paper roll diameter decreases gradually as the sheet is unwound. A sheet length measuring sensor or rotary encoder is provided in the paper feed path through which the packaging sheet unwound from the paper roll is fed toward the packaging unit. An angle sensor is provided which comprises Hall element sensors provide on a support shaft and magnets provided on a core pipe of the paper roll. Any change in the signals from one of these sensors relative to the signal from the other sensor is used to calculate the paper roll winding length, and the sheet tension is adjusted to an optimum, constant level by controlling the sheet braking force stepwise according to the roll diameter measured by the sensors.
