Converting Equipment by Winding Type
Center Winding Slitter Rewinders
Center winding is a common method of rewinding materials that may have varying thickness across the width of the roll. The material passes through both a nip and anvil roll is slit utilizing an appropriate slitting method, and is rewound onto a core that is driven by the shafts they are placed on. This method of rewinding is common for materials such as tapes, films, foils, foams, woven materials, and materials that may be sensitive to compression and higher tension settings.
Turret Winding Slitter Rewinders
Turret winding is is a variant of center winding that is designed to minimize machine downtime. This method of slitting utilizes multiple shafts and allows the machine to continue slitting on an active shaft while an operator or automatic mechanism unloads and resets the finished shaft. This method is designed to maximize throughput, minimize changeover time, and is commonly used for tapes, consumer goods, wipes, paper goods, and many other high volume products.
Surface Winding Slitter Rewinders
Surface winding, otherwise known as drum surface winding is a method of rewinding materials commonly used for rolls of extensible and non-extensible material with large diameters. Common materials that are better suited for the Surface Rewinding method include non-wovens and paper.
Center Surface Slitter Rewinders
The center surface winding method of rewinding combines elements from traditional surface rewinding and center winding. This method of rewinding is common in applications where materials such as non-wovens are slit to smaller widths. As the diameter of the slit rolls increase, the rewinding center shafts maintain tension, help to ensure contact with the drum, and help to ensure slit separation.
