Automatic Paper Slitter and Rewinding Machine

Abstract

Nowadays, automation plays a key role in all over the industries. Due to the demand of using paper is growing day by day, efficiency and quality is need to be improved in the process of paper mill.  Although, paper making involves the use of several different processes and machines.  The slitter-rewinder is an essential part of any paper mill.  Unwinding of large, main freshly produced rolls from paper making machine, cutting it into smaller length, and rewinding it to smaller  rolls for delivery is the job of a slitter-rewinder machine. Any issue with the slitter-rewinder, which is one of the production process in the paper mill, will cause entire mill to shut down.  This paper explains how  the various stages in the process is converting the manually operating rewinding and slitter machine into fully automated rewinding and slitter machine. The basic concept uses load cell based tension controller, nip reliving rider roll using PID proportional valve, HMI, and PLC to carry out the process. The main idea is to automate the process to avoid paper breakage and bring in optimal time management and quality rewinding.
