THE ROLE OF SPRING IN THE SLIVER HANDLING SYSTEM 1. Types of Springs Box Spring Pantograph Spring Spring Bottom
2. The Spring & Its Effect
It helps maintaining constant height between the top layer of sliver coils and lifting roller As the sliver is withdrawn, the pressure on the spring progressively reduces
3. Influence of Fibre Density The deformation of spring depends upon how much weight is acting on it While filling the can with voluminous fibre a stiffer spring will be beneficial as it will create more pressure on the sliver column
4. Effect of Spring Load & Storage Time on U% Because of being at high storage time chances of fibre leaking from adjacent sliver coils are high
5. Effect of Spring Load & Coil Position on Strength CV% Bottom sliver coils from reduced spring stiffness of older sliver can give higher strength CV% Long thin places may be introduced in final yarn and strengthen single combed yarn Source : https://cutt.ly/1XUVA08
