Yarn Tension PID Control of Air–Jet Texturing and Twisting Machine Using a Programmable Logic Controller (PLC)

This paper defines a PID type yarn tension control run by a PLC system that is used to control the yarn tension below the twisting head of the novel air jet texturing and twisting (AJT) machine. In the standard sequence of the AJT, if the yarn is transported to the twisting and winding head with a low tension value, the yarn is bound to wrap around the shoulder below the twisting head and break...

Propagation of tension along a polymer chain.

We study the propagation of tension caused by an external force along a long polymeric molecule in two different settings, namely along a free polymer in three-dimensional (3D) space being pulled from one end, and along a prestretched circular polymer, confined in a narrow circular tube. We show that in both cases, the tension propagation is governed by a diffusion equation, and in particular, ...

On the Mechanical Analysis and Control for the Tension System of the Cylindrical Filament Winding

The constant winding tension can make the filament arranged in order. The stress distribution between the filament balance fully gives play to the enhancement of filament, and increases the intensive workload of the composite winding material. This paper conducts the mechanical analysis for the unwinding roller and tension measuring roller of the cylindrical winding machine so that gets the mec...

Wilson Loop on a Light-Cone Cylinder

QCD without matter and quantized on a light-cone spatial cylinder is considered. For the gauge group SU(N) the theory has N − 1 quantum mechanical degrees of freedom, which describe the color fux that circulates around the the spatial cylinder. In 1+1 dimensions this problem can be solved analytically. I use the solution for SU(2) to compute the Wilson loop phase on the surface of the cylinder ...
