Slitting Winder Rebuild
Slitter winders are under the heavy stress due to continuous acceleration and deceleration, mechanical movement of equipment and winding of paper in high speed. When the winders are getting old there exists mechanical play, wear and tear of parts, leakage of hydraulic oil and difficulty to get certain spare parts.
Winder efficiency can be improved with smaller investment than having totally new winder. Changing of new slitting knives, new core chuck guides, bearings and improving of roll hardness control are typical parts of winder rebuild.
Sometimes the paper grade has been changed and there is lighter or heavier web grades more numbers of knives and higher requirement of production tons. Getting off from the dust generating D-bar spreader system by new rotating section spreader rollers. All these can be considered in rebuild project. Roll hardness control together with automation system upgrade will give more value to production and improve shipping roll quality.
Take care of safety
At same time with rebuild the winder safety system is taken under the new requirement. Safety fences, safety carpets, E-stop buttons and -wires will take care of operators safe work environment.
