Abstract: A restraint system for a vehicle, includes a rotatable reel, a flexible tether, a first shaft and a conductor member. The flexible tether has a first end coupled to the reel and a second end. The tether is wound upon the rotatable reel and movable in both a winding direction and an unwinding direction. The first shaft is configured to be operably coupled to the rotatable reel, and includes a plurality of magnetic elements affixed thereto. The conductor member has a hollow interior. At least a portion of the first shaft and at least a portion of the plurality of magnetic elements are disposed within the hollow interior. Movement of the tether in the unwinding direction causes relative movement between the plurality of magnets and the conductor member. Eddy currents within the conduct member generate a retarding force on the first shaft.

Abstract: An electropolishing or electroplating system and method for metal conveyor belts is described. In some embodiments, the system has a metal conveyor belt held in constant tension; a tank for holding an electrolytic fluid, the tank having an interior space suitable to contain the fluid, a metal plate and the metal conveyor belt; and an electrical current supply. In an electropolishing application, the current passes from the metal conveyor belt, through the fluid and into the metal plate. In an electroplating application, the current passes from the metal plate, through the fluid and into the metal conveyor belt.

Abstract: A winding apparatus providing steady tension includes: a loading unit rotatably supporting a roll of a sheet, releasing the sheet, and outputting an angle signal and a torque signal; a winding unit adapted to collect the sheet into a roll form; a dancer roller and a tension sensing unit separately arranged between the loading unit and the winding unit and outputting a shift signal and a tension signal respectively; and a control module having a calculating unit and a command unit. The calculating unit electrically connects with the loading unit, the dancer roller and the tension sensing unit to receive the signals and generates a torque command signal. The command unit electrically connects with the calculating unit and the loading unit to receive the torque command signal and produces a control signal by the torque command signal or a velocity signal.

Abstract: This present invention relates to a process for winding tape to prevent or reduce telescoping of the tape (e.g., dental tape) as it is wound onto a bobbin spool. Dispensers comprising such bobbins are also discussed herein.

Abstract: A general winding and feeding apparatus includes a rotating shaft on the upper side of a standing wall of a base, and a motor is connected to the rotating shaft in the standing wall. A swing arm extends across a traveling material and is situated at a suitable position on the standing wall. Digital variable frequency methods may be used to drive the motor, which operates in conjunction with light-coupled sensors to detect the traveling speed of a material on the swing arm and sense a swing position of the swing arm. Feedback is generated in real-time to modify the speed of the motor, and the constant speed travel of the material can be achieved while being either wound or unwound.

Abstract: A variable representing runnability of a paper web to be manufactured with a paper machine or processed with a finishing apparatus is measured and the speed difference between operational groups of the paper machine and/or the finishing apparatus is adjusted on the basis of the measurement of said variable such that the moisture profile of the paper web is measured substantially along the entire width of the paper web, the minimum and maximum values for moisture are defined on the basis of the moisture profile, a drawing window describing the allowable tension to be directed to the paper web is defined, the lower and upper limits of the drawing window being defined on the basis of the minimum and maximum values for moisture, and the speed difference between the operational groups is adjusted so that the paper web tension is within the range defined by the drawing window.

Abstract: Apparatus and method for controlling the winding of a sheet of material such as paper and film finished consumer products into a log using an adjustable reference profile. The apparatus and method may provide improved process control, product quality, manufacturing production rate and/or process repeatability. The apparatus and method provide more consistent finished log properties by measuring at least one process parameter during the manufacturing process. The process parameter is then correlated with the desired finished product characteristics and an appropriate correction is made to the reference profile.

Abstract: A winding apparatus, such as a slitter rewinder, designed to shorten a distance between an unwinding shaft and a winding shaft, thereby downsizing the apparatus and attaining a significant cost reduction. To that end, in unwinding a web from the unwinding shaft, either to wind it onto the winding shaft or to slit it in the elongate direction into plural narrow-width webs and separate them alternately vertically or longitudinally, followed by winding onto respective winding shafts, the unwinding shaft is driven at a preset web speed, the winding shaft is driven at a preset web tension, guide rollers for guiding the web are disposed between the unwinding and winding shafts to thereby leave the guide rollers to rotate freely by contact with the web without their direct driving.

Abstract: A system and method is provided for developing speed and rotation count profiles for controlling the spindle drive on a towel winder system for winding rolls of paper, such as tissue or towel. The system and method monitors accumulated paper sheet length metered onto the winding spindle to control desired sheet count and finished roll dimension data. The system and method utilizes the accumulated paper sheet length and the desired finished roll data to calculate an instantaneous diameter. The instantaneous diameter calculation includes determining an effective thickness of the roll based on two forms of calculating finished roll cross-sectional area. The system and method also includes monitoring the actual line surface speed. The instantaneous diameter and the actual line surface speed are used to generate a speed reference signal and an inertia compensation signal. An outer compensation loop can be employed to trim the speed reference signal so that the revolution count can be controlled.

Abstract: Method and apparatus for monitoring a winding hardness of a winding roll when winding a material web. A series of marks are placed on the material web at a first location as it is wound onto the winding roll. The distance between two successive marks is detected at a second location. The detected distance of two successive marks is used to determine a stretch of the material web.
