Application of WECON VC Inverter in Uncoiler Machine

1. Industrial Introduction

An uncoiler is a mechanical device used to smoothly unwind and transport rolled materials (such as metal sheets, paper, plastic films, etc.), achieving continuous and stable material processing through mechanical transmission and control systems.

2. Control Progress & Requirements

This series of production lines is used to uncoil, level, set dimensions, and cut metal or other material coils of different specifications into flat sheets of the required length and width. It is suitable for processing cold-rolled sheets, galvanized sheets, color-coated sheets, stainless steel sheets, and other sheets.
