Modelling of the winding process on rewinding machines

Abstract

This paper presents a simulation of the rewinding process using SolidWorks Motion. The study focuses on the interaction between various rolling-in rollers and accumulated packages, comparing simulation results with analytical calculations. It includes determining the package stiffness experimentally and modelling the winding dynamics, considering factors like friction, roller radius, rewinding speed, and other parameters. Simulations were performed for four roller types and different package body thicknesses. The results demonstrated the model's accuracy, showing a 95% approximation to analytical calculations. Key findings include the reduction of slipping with element rollers and the effect of package body thickness on contact length. These results can help optimise rewinding processes and improve the design of rewinding machines and friction gears. Further research is needed to analyse the rebound or loss of contact between the roller and the package.
