Rotoflex Printing Machines VSI – VERSATILITY
Rotoflex Printing Machines line of high speed, Inspection Slitting and Rewinding machines have earned the reputation of being robust and dependable. From the small VSI models to the larger, more sophisticated VLI models, ROTOFLEX International maintains the highest level of product quality to ensure trouble-free operation for years to come
With an emphasis on maintaining web control, through starts, stops and speed changes, Rotoflex Printing Machines integrates the latest web inspection and finishing technologies to continually improve machine performance and enhance product quality. Operator comfort and convenience are features integral to every Rotoflex Printing Machine.
Supported by a full electronics package, with quick setup features and easy-to-use controls, the operator maintains a full view and has total control of the three critical functions of inspection, slitting and rewinding.
Electronically detected or visually observed faults are easily remedied using an adjustable splicing table to ensure that only good product is rewound for shipment to your customer.
Using the latest in electronic web guiding technology, the web is precisely positioned for ultimate slitting accuracy and different rewind core size requirements are easily accommodated by the quick-change interchangeable rewind shaft design.
