The LR250 Label Inspection Rewinder can process label rolls up to 250mm wide (up to 9.8 inches) at a high production speed of 200m per minute (656 feet per minute). It comes with two-way rewinding capability, integrated web guide and a label counter as standard. The adjustable splice table features pneumatic splice clamps and can be fitted with a splice detector.
The product has been built as a flexible entry-level model to boost everyday productivity and comes with a built-in sensor for missing label detection. For more demanding applications, such as pharmaceutical labels, the LR250 can be configured with a video camera for 100% advanced print inspection and verification.
‘The LR250 is a versatile machine with some innovative built-in features that will ensure all your rolls are delivered in top condition with all labels present and correct,’ said CEO Uffe Nielsen. ‘We have developed the rewinder with different inspection options, so there is a version that suits every budget without compromising on quality.’
The missing label feature works with a sensor. Any missing label that is detected will cause the machine to stop. The computer will then calculate the position of the error and reverse the web until it is aligned with the splice table. Once the missing label has been replaced, the web is re-checked and the rewinder completes the job at full speed.
The option to integrate a video camera upgrades the capabilities of the machine to include full print quality inspection. Grafisk Maskinfabrik (GM) has partnered with BST-Eltromat and Nikka Research to offer the latest in 100% quality inspection for printed labels. The camera will be connected to an external system, which checks the print for faults and verifies it against the master PDF file.
The LR250 has further been developed with tension separation for working with thin, sensitive materials and PET liners. Thanks to the centrally placed nip roller, the web can be unwound with one tension and rewound with a different tension to avoid stretching the material. A capacitive sensor for clear-on-clear labels can further extend the range of materials that can be processed.
For customers requiring variable data, there is space to add a full UV inkjet printer for coding and marking. GM works directly with leading suppliers Domino, Markem-Imaje and Rea Jet, but systems from other manufacturers can also be fitted on demand.
‘As fault-free label production has become the norm. Our customers want machines that enable them to deliver perfect rolls of labels to their customers, every time,’ said Nielsen. ‘This little label inspection rewinder is the perfect solution for that, but don’t let the size fool you. We have built the LR250 with so many clever options that it can grow with our customers’ business and tackle a wide range of label requirements.’
