A winding tension measure device (85) measures the winding tension to the POF (17).
Consequently, the occurrence of wrinkles and baggies can be suppressed during the winding-up operation and a winding collapse can be prevented from occurring by increasing a winding tension.
The winding reel is easily carried and stored, and has a sufficient strength to stand against the winding tension of the wound photosensitive film.
The interactive effects are a criterium for the winding tension.
The aim of the invention is to measure the resulting winding tension, which varies along the radius, whereby physical interactive effects can be measured.
Since winding cores (33) can be individually rotated, a web can be taken up with stable take-up tensile force.
prestressing: The process of applying auto-frettage or controlled tension winding.
The gate windings (16, 18) are driven by an oscillator driver (24) that generates a gate winding current and a gate winding voltage.
When the gate winding voltage becomes equal to the reference voltage, the feedback circuit (42) is stable and the gate winding current is set to a desired zero current operating point.
The coiling device may include a feedback loop braking one or both spools and allowing the coiling tension to be programmed to a desired level.
The coiling device may include a feedback loop braking one or both spools and allowing the coiling tension to be programmed to a desired level.
The system control (116) includes an electronic voltage measurement circuit to measure a winding voltage (113, 114) of the motor winding (102, 103).
A reference voltage and the gate winding voltage are applied to a feedback amplifier (44) in the feedback circuit (42).
And the windings form Wi (current winding of the electric meter) and Wu ( winding of the voltage of the electric meter).
The present invention provides a center feed roll (10) including a wound sheet material having lessened wound tension due to exposure to moisture.
Threads are wound onto a warping drum (3) at a constant winding tension by a warp creel (C) and via a deviating roller (1), forming a warp section (M).
Disclosed is a reel for winding photosensitive film (6) which stabilizes the winding shape of the film and minimizes the deformation of a photosensitive layer caused by the winding tension.
In a subsequent winding step, this film is wound on a cylindrical core at a film winding tension of 5-40 kgf per meter of the width to form a roll.
For fans and pumps and other variable-torque applications, the power supply (1) maintains approximately a constant ratio of main-winding voltage to the square of frequency.
In one embodiment, a switching controller uses an auxiliary winding voltage of a transformer to form a signal representative of current flow through a secondary winding of the transformer.
