Winder

Winders (Fig. 3.19) are used to collect the wound roll packages. They generally operate in a manner that produces rolls of constant web tension, as opposed to operating at a constant winding (rotational) speed. There are two primary winder types surface winders and axial winders. 

Because of their simple, economical design, surface winders tend to be the more popular of the two. They operate by employing a motor-driven contact roll at the him roll surface. The contact roll essentially lays the him onto the rotating him roll. As the him roll diameter increases, the axis of the him roll moves in a path that separates it from the contact roll, maintaining pressure at the surface. This system is used mainly for medium- and high-tension rolls. 

Axial (or center) winders are often used when low-tension roll packages are required. In these systems, the central axis of the him roll is motor-driven rather than the contact roll. This type of winder tends to be more expensive than the surface winder.

In earlier years, the windup speed was 275—375 mpm (m /min) with 0.5 kg of yam per bobbin. In the 1990s, winders are designed for 10—25-kg bobbins, two or more bobbins per winder, operating at speeds up to 6000 mpm, and equipped with automatic bobbin changers.

There are many different equipment options avaQable to suit specific product needs including continuous winders for pipe, multiaxis winders for pressure vessels, and simple lathe-type winders for tanks and large pipe. Specialty machines combine a chopped reinforcement with continuous fibers for tank walls and large-diameter pipe where both stiffness and tensQe strength are required. Textile braiders have also been adapted for use as continuous... 

Typical applications for adjustable-voltage, adjustable-speed dc drives include winders, paper machines and auxiliaries, blending systems, feeders, extruders, calendars, machine tools, range and slasher drives, cranes, hoists, shovels and draghnes, and an almost unhmited variety of drives requiring the flexibility and efficiency possible with direct current. 

FOC drives are capable of providing precise speed control and are used for applications calling for high performance and precision (e.g. machine tools, high-speed elevators, mine winders, rolling mills, etc.). These drives are capable of regulating a number of variables at the same instant such as speed, position, acceleration and torque. 

I In both the above types of braking systems, a hand-operated device is also provided, to release the mcehanieal brakes in applieations such as lifts, elevators, cranes, and winders. This... 

As the basic fiber microstructure is determined during the spinning and drawing processes, several spinning process variables have a significant impact on fiber properties e.g., flow rate, winder speed, spinnerette geometry, etc.). Spinning... 

Most induction ac motors are fixed-speed. However, a large number of motor applications would benefit if the motor speed could be adjusted to match process requirements. Motor speed controls are the devices which, when properly applied, can tap most of the potential energy savings in motor systems. Motor speed controls are particularly attractive in applications where there is variable fluid flow. In many centrifugal pump, fan, and compressor applications mechanical power grows roughly with the cube of the fluid flow. To move 80 percent of the nominal flow only half of the power is required. Centrifugal loads are therefore excellent candidates for motor speed control. Other loads that may benefit from the use of motor speed controls include conveyers, traction drives, winders, machine tools and robotics. 

Filters of the automatic roller type need to have an independent manometer, which will give warning in the event of malfunction of the winder.

A numerically controlled filament winder has been designed and constructed. The distance between the head-stock and tail-stock is six feet. Clearance between the centers emd the body of the winder is adjustable, but a specimen several feet in diameter could presently be fabricated. The mandrel and carriage are each driven by one horsepower, direct current motors with a maximum 2000 revolutions per minute. Three phase, 480 volt alternating current is transformed to a 90 volt, direct current power supply. A gear... 

Additional patterns have been simulated, including near 0 to about 90 helices. Test cylinders have also been wound with roving. The graphical presentation is effective for conformation before winding and demonstrates the successful development of a numericeiUy controlled, filament winder.
