Mill Duty Winders

Servall State of Art Winders

Servall state of art high speed winders are products of two decades of Research & Development as well as experience from past installations. With the ever increasing paper machine speeds and deckles, Servall winders have been built for maximum speeds up to 2300 mpm as well as widths up to 5 mtrs and are capable of handling wide range of papers literally from Tissue to Board. Each individual component & sub system has been designed, engineered and selected to obtain best performance levels from Servall Winders.

Servall winders are built around system integrating the best components & sub systems from abroad like Automatic slitting stations from Diennes Germany/ Tidland, USA, Linear Motion guides from Rexroth, Germany/ Thk, Japan, Hydraulic Cylinders from Rexroth, Germany/ Parker UK etc. ensuring best performances from the Winders. The equipments are provided with latest drive, automation and instrumentation technologies for scaling new levels of machine efficiencies along with strictly adhering to international standards.

Two Drum Winder

Servall Two Drum Winder achieves outstanding winding results even with large reel diameters. Servall Two Drum Winder has a simple and easy operation leading to several advantages such as high slitting quality, large finished reels, high output, low downtimes and auto set changes. They can handle a variety of grades such as Writing & Printing, Newsprint, Hard Tissues, Tetrapacks, AFP, Cigarette Tissues, Booklet Tissues, Copier Papers, Kraft and Coated Board.

High Winding quality is guaranteed by the shaftless rewind with positive guidance of the counter loaded rewind carriages and the auto controlled Rider roll nip relieving. In addition, the hardness (initial and final) of finished rewound reel can be adjusted through two motor digital drive controls. A solid and rigid structure and larger Winder drums ensure vibration free smooth winding of finished reels. A special surface coating on Winder drums ensures better winding. Linear guides and bearings ensure a longer, friction free and maintenance free life. Web threading equipment is provided for easy handling during threading. Tension control is ensured through Electro-pneumatic control systems and measurement through a pair of load cells. The auto set change of finished reels through PLC, reduces downtime on winding operation.

Salvage Winders

Salvage winders used for salvaging rewound reels and reduce losses to a minimum. Can also used as Rereelers.

Sheet Cutters

Servall's new Sheet Cutter has been developed to meet specific requirements of the finishing house. Servall Sheeter results in optimum productivity by reducing loss in the finishing house. The compact simplex sheeter has simple adjustment programme for sheet length and angle correction, which gives incredible sheet size accuracy, preventing wastage. Servall sheeter enables perfect piling in ready-to-deliver condition. The Modular system reduces erection and commissioning time and has easy operating procedures.
