The invention discloses an apparatus for regulating winding tension as function of bobbin (2) diameter in a slit film tape or yarn (1) winder system carrying at least one automated winder. It comprises a dancing arm (3) equipped with a tension setting means or device (3B) which regulates the yarn tension. The inventive feature of the invention is that tension setting means (3B) is capable of changing resistance R of the dancing arm (3) as a function of the bobbin (2) diameter D during the winding process. The invention also provides a method for regulating winding tension as function of bobbin (2) diameter. The invention helps overcome a number of problems related to uniformness and consistency of package the fabric making industry is currently facing. It solves technical problem of winding bobbin throughout using same tension adjusted for dancing arm, resulting higher tension during unwinding at low bobbin sizes. It also helps reduce the necking or shrinkage of the fabric produced due to varying resultant winding tension.

An improved system for handling delicate linear media and in particular to a method and apparatus for winding delicate linear media such as superconducting wire or tape or optical fibers onto a spool. A combination of direct closed loop control and media routing design facilitates the handling of the delicate media without causing damage. The axial tension in the linear media may be closely controlled during winding by means of feedback control loop using tension measurements to control the rotation speeds of the wind-from and wind-to spools. Further, during winding, the delicate linear media is only exposed to large radius bends with no reverse bending. Finally, output devices and features, commercial or otherwise, made possible by delicate linear media handling are revealed. This includes advanced SC devices and features.

The invention relates to a method for controlling rotation of a winding spool (30) onto which an optical fiber (100) is wound in a proof-testing machine, the optical fiber being guided in the proof-testing machine at a given line speed from an input pulling device (10) to an output pulling device (20), then to the spool (30), the input and output pulling device being arranged to subject the optical fiber to a predetermined tensile stress, the method comprising: upon detection of a break between an output point (A) of the input pulling device and between an input point (B) of the output pulling device, a step of controlling the rotational speed of the spool to bring it to a complete stop; a step of passing the optical fiber between an output point (C) of the output pulling device and an input point (D) of the winding spool in a fiber accumulation zone (90) adapted to accumulate a predetermined fiber length preventing an fiber broken end resulting from the break going beyond the input point (D) of the winding spool.

A capstan includes a lift motor, a flexible lifting member, and a tether assembly. The lift motor is operatively connected to a shaft. The flexible lifting member includes a first end and a second end. The first end is connected to the shaft. The flexible lifting member connects a lift assembly to the lift motor via the shaft. The tether assembly includes a switch arranged between a portion of the flexible lifting member and a portion of the capstan. The second end is connected to the tether assembly. The switch acts as a safety in case of a broken flexible lifting member and allows for an automated unloading cycle.
