An optical fiber winding mechanism feeds an optical fiber from raw material bobbins and winds the optical fiber around a winding bobbin, and includes a first raw material bobbin-side unit to mount the first raw material bobbin thereon, a second raw material bobbin-side unit to mount the second raw material bobbin thereon, a winding bobbin-side unit to mount the winding bobbin thereon, and a controller to control each of the units. The first raw material bobbin-side unit includes a body device, a head capable of rotating with respect to the body device, a rotation assist device capable of engaging with the head, a rotation mechanism capable of rotating the body device around a Z direction, and a slide mechanism capable of moving the rotation mechanism.

Described are, among other things, methods and devices for providing a learning procedure in a yarn feeding arrangement (12). The learning procedure aims at providing control data to the controller (32) about system components and behavior of system components of the yarn feeding arrangement beforehand, such that the controller has knowledge of the system components before the weaving machine (10) is started to operate at full operational speed.

A baler twine tension control assembly including a displacement detector and elements defining a twine path. The twine path enters and exits the twine tension control assembly and within the twine tension control assembly extends across a first fixed location and a second fixed location as well as across an intermediate displaceable location located between the first fixed location and the second fixed location. The displacement detector is connected to the intermediate displaceable location and generates a signal indicative of the displacement of the displaceable location.

The invention discloses a rigid-flexible coupling mechanism with variable rod length for fibre bundle tension control. In the transmitting process, the fibre bundle passes through the front guide roller, the tension regulating roller and the back guide roller sequentially. The front and back guide rollers have fixed positions, while the tension regulating roller has an adjustable position to regulate the fibre bundle tension. The invention uses the variable rod length rigid-flexible coupling mechanism with a combination of a servo motor and an electric actuator in a dual drive control mode, which can choose to use either a four-rod fixed length mechanism or a five-rod variable length mechanism to regulate the tension under different working conditions. This provides a more flexible control method, increases the regulating range of fibre bundle tension, improves the system response speed and regulation accuracy, and effectively avoids the wear of fibre bundle caused by tension fluctuations.

A cable tension control device includes a pair of first active rollers clamping a cable therebetween, a first driver driving the first active rollers, a pair of second active rollers clamping the cable therebetween at an upstream position from the first active rollers, a second driver driving the second active rollers, a floating roller arranged between the first active rollers and the second active rollers and exerting a pushing force on the cable, and an actuator driving the floating roller to move vertically to adjust the pushing force exerted on the cable. A tension force applied on the cable is controlled to be equal to a predetermined tension force by controlling the pushing force and by controlling a speed difference between a first speed at which the first active rollers convey the cable forward and a second speed at which the second active rollers convey the cable forward.
